Mercury, traveling in its 88-day-long orbit around the Sun with basically zero axial tilt, has many craters at its poles whose insides literally never see the light of day. These permanently-shadowed locations have been found by the MESSENGER mission to harbor considerable deposits of ice (a seemingly ironic discovery on a planet two-and-a-half times closer to the Sun than we are!*) But if there are places on Mercury where the Sun never shines (insert butt joke here) then there may also be places where it always does. That’s what researchers are looking for in illumination maps made from MESSENGER data…...

The green rock found in Morocco last year may be the first known visitor from the solar system's innermost planet, according to meteorite scientist Anthony Irving, who unveiled the new findings this month at the 44th annual Lunar and Planetary Science Conference in The Woodlands, Texas. The study suggests that a space rock called NWA 7325 came from Mercury, and not an asteroid or Mars. NWA 7325 is actually a group of 35 meteorite samples discovered in 2012 in Morocco. They are ancient, with Irving and his team dating the rocks to an age of about 4.56 billion years. Irving...

Did you know that consumption of high fructose corn syrup (HFCS) in the U.S. -- which can be found in a plethora of cookies, candies and fast-foods -- has increased by a a whopping 10,673 percent between 1970 and 2005? So reports the USDA Dietary Assessment of Major Trends in U.S. Food Consumption report. Are you one of millions, who, according to the USDA report, consume one-quarter of your calories from added sugars, most of which comes from high fructose corn syrup, as mercola.com pointed out? Meanwhile, have you heard about the a recent study, which reveals that a diet...

Explanation: The colors of the solar system's innermost planet are enhanced in this tantalizing view, based on global image data from the Mercury-orbiting MESSENGER spacecraft. Human eyes would not discern the clear color differences but they are real none the less, indicating distinct chemical, mineralogical, and physical regions across the cratered surface. Notable at the upper right, Mercury's large, circular, tan colored feature known as the Caloris basin was created by an impacting comet or asteroid during the solar system's early years. The ancient basin was subsequently flooded with lava from volcanic activity, analogous to the formation of the lunar...

Explanation: Have you ever seen the planet Mercury? Because Mercury orbits so close to the Sun, it never wanders far from the Sun in Earth's sky. If trailing the Sun, Mercury will be visible low on the horizon for only a short while after sunset. If leading the Sun, Mercury will be visible only shortly before sunrise. So at certain times of the year an informed skygazer with a little determination can usually pick Mercury out from a site with an unobscured horizon. Above, a lot of determination has been combined with a little digital manipulation to show Mercury's successive...

Scientists working on Nasa's Messenger probe to Mercury have shown off a stunning new colour map of the planet. It comprises thousands of images acquired by the spacecraft during its first year in orbit. This is not how we would see Mercury, which would look like a dull, brownish-grey globe to our eyes. Rather, the map represents an exaggerated view of the planet that is intended to highlight variations in the composition of its rock. "Messenger's camera has filters that go from the blue to the near-infrared of the spectrum, and we are able to use computer processing to enhance...

The import or export of mercury is set to be banned © ShutterstockAfter six days of complex discussions in Geneva last week, governments from around the world agreed to a global, legally-binding treaty on Saturday to limit mercury use. This is the first new major environmental treaty in over a decade.The Minamata Convention on Mercury – named after the Japanese city where thousands of residents fell ill with mercury poisoning in the 1950s – covers a range of products and processes where mercury is used or released. Countries will be invited to ratify the treaty, which took four years to...

While we all know mercury is poisonous it is methylmercury, the organic form, that bioaccumulates in food webs and is highly toxic. It's been acknowledged for years that methylmercury is produced by microorganisms far down the food chain, but what has not been known is how they do it. US-based researchers at Oak Ridge National Laboratory in Tennessee have now identified the genes, and hence the proteins, involved in mercury methylation and suggest that the pathway is common for all mercury methylating microorganisms.Using gene deletion, Jerry Parks' team showed that two genes are key components of bacterial mercury methylation, relating...

Explanation: Innermost planet Mercurywould probably not be a good location for an interplanetary winter olympics. But new results based on data from the Mercury orbitingMESSENGER spacecraft indicate that it does have substantial water icein permanently shadowed regions within craters near its north pole. The possibility of ice on Mercury has been entertained for years, inspired by the discovery of radar bright, hence highly reflective, regions near the north pole. Highlighted in yellow in this map based on projected MESSENGER images, radar bright regions are seen to correspond with floors and walls of north polar impact craters. Farther from the pole...

New observations by the MESSENGER spacecraft provide compelling support for the long-held hypothesis that Mercury harbors abundant water ice and other frozen volatile materials in its permanently shadowed polar craters. Three independent lines of evidence support this conclusion: the first measurements of excess hydrogen at Mercury's north pole with MESSENGER's Neutron Spectrometer, the first measurements of the reflectance of Mercury's polar deposits at near-infrared wavelengths with the Mercury Laser Altimeter (MLA), and the first detailed models of the surface and near-surface temperatures of Mercury's north polar regions that utilize the actual topography of Mercury's surface measured by the MLA. These...

Are kids' school lunches safe? A new report from the advocacy group Mercury Policy Project finds tuna served as school lunches in some states may contain levels of mercury that the organization deems toxic. Mercury is a naturally occurring neurotoxin in the environment that can be released into the air through industrial pollution. It builds up in water and streams and turns into methylmercury, a compound which is then absorbed by fish as they feed. The report, called "Tuna Surprise" is the first to test canned tuna sold to schools, according to its authors. "Most children are already consuming only...

As President Obama’s Environmental Protection Agency continues to receive much-needed scrutiny as it conducts its reign of terror (“crucifying”) on fossil fuel industries, yet another renegade regional administrator has been shown in full alliance with environmental extremists in pursuit of regulations to kill oil and coal. Natural gas isn't far down the hit list. This time it’s Region 5 Administrator Susan Hedman, a veteran attorney who has litigated environmental cases as part of the University of Maryland Environmental Law Center, as counsel for the Environmental Law and Policy Center, and as senior assistant attorney general in the Illinois Attorney...

Explanation: Can you spot the planet? The diminutive disk of Mercury, the solar system's innermost planet, spent about five hours crossing in front of the enormous solar disk in 2003, as viewed from the general vicinity of planet Earth. The Sun was above the horizon during the entire transit for observers in Europe, Africa, Asia, or Australia, and the horizon was certainly no problem for the sun-staring SOHO spacecraft. Seen as a dark spot, Mercury progresses from left to right (top panel to bottom) in these four images from SOHO's extreme ultraviolet camera. The panels' false-colors correspond to different wavelengths...

These days, most people consider themselves lucky if a new car lasts 5 to 10 years. Make it to 100,000 miles in your vehicle, and the car company might make a commercial about you. That makes 93-year-old Rachel Veitch a notable exception. Veitch is retiring her 1964 Mercury Comet Caliente after more than 576,000 miles on the road. "I am legally blind, so I can no longer drive my lovely Chariot," Veitch told FoxNews.com. "They don't have to take it away, I would not dream of driving that car again." The car itself is fine, but Veitch has macular degeneration...

After 576,000 miles--or more than a trip to the moon and back--in the same 1964 Mercury Comet Caliente, the 93-year-old Orlando grandmother is stepping on the brakes due to age-related macular degeneration in both eyes. She realized her vision had completely failed her in early March after running a "bald-faced red light," Veitch told FoxNews.com. "I am legally blind, so I can no longer drive my lovely Chariot," she said by phone. "They don’t have to take it away, I would not dream of driving that car again."

An interesting story surrounds last month's 50th anniversary celebration of the Mercury-Atlas 6 manned space flight... John and Annie Glenn with VP Johnson, 1962 John Glenn's own true heroFor half a century now the world has applauded John Glenn as a heart-stirring American hero. He lifted the nation's spirits when, as one of the original Mercury astronauts, he was blasted alone into orbit around the Earth; the enduring affection for him is so powerful that even now people find themselves misting up at the sight of his face or the sound of his voice. But for all these years, Glenn has...

Explanation: What are those unusual features on planet Mercury? The slightly bluish tinge of features dubbed hollows has been exaggerated on the above image by the robotic MESSENGER spacecraft currently orbiting Mercury. The rounded depressions appear different than impact craters and nothing like them has been noted on Earth's Moon or anywhere else in the Solar System. The above image is a section of the floor of Raditladi impact basin about 40 kilometers wide that includes the mountains of the central peak. One progenitor hypothesis is that the hollows formed from the sublimation of material exposed and heated during the...

Ten days before the 2008 presidential election, as blame was beginning to be laid out for John McCain’s “likely defeat,” a top communications adviser to the campaign wrote a detailed strategy memo focused on how to preserve the reputation of another key adviser, Steve Schmidt, POLITICO has learned. *** The protective maneuver sheds more light on the final days of the 2008 campaign, a period of low morale marked by tensions between the Palin and McCain camps and the expectation of defeat. *** “Thankfully, and rightfully so, some members of the political punditry are already coming his defense (Rove, McKinnon,...

In December 2011, the Environmental Protection Agency released new Clean Air Act “National Emission Standards for Hazardous Air Pollutants.” Once again, EPA Administrator Lisa Jackson touted the supposedly huge benefits of controlling emissions of mercury (Hg) and other air toxics from U.S. coal- and oil-fired power plants (or electric generating units, EGUs). The people of Idaho may welcome this new rule, since EPA’s miraculous modeling machine has promised to prevent “six premature deaths” and create “up to $54 million” in health benefits by 2016 – even though not one coal-fired EGU in Idaho fits the EPA’s final rules. Even the...

The is the first in a multi-part series of articles exposing the lies and misinformation behind legislation mandating the replacement of incandescent light bulbs with potentially unsafe compact florescent light (CFL) bulbs. ------- According to provisions of legislation passed by congress in 2007, the 100-watt incandescent bulb was to be off the shelves this January, followed by a phase-out of the 75-watt version in January 2013 and the 60- and 40-watt versions in January 2014. But last month congress granted consumers a reprieve by including in its spending bill a measure delaying enforcement of the ban until the end of...

By Kirk Myers, Seminole County Environmental News Examiner This article, the second in a series, focuses on the misleading performance claims surrounding the “more energy efficient” compact fluorescent light (CFL) bulbs now replacing traditional incandescent bulbs. These potentially harmful mercury-filled lamps (see my previous column describing the dangers) are being forced on consumers by the U.S. congress with support from the Green Lobby and light-bulb manufacturers like GE, Sylvania and Phillips. These and other manufacturers stand to make huge profits selling the more expensive CFLs (more on that issue in my next column). There is a growing body of evidence...

Scientists have uncovered a lot about the Earth's greatest extinction event that took place 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system. "No one had ever looked to see if mercury was a potential culprit. This was a time of the greatest volcanic activity in Earth's history and we know today that the largest source of mercury comes from volcanic eruptions," says Dr. Steve Grasby, co-author of a...

To understand how the Environmental Protection Agency operates, one must first understand that it lies all the time. Its “estimates” are bogus. Its claims of lives saved are bogus. It thrives on scare-mongering to a public that is science-challenged, but the science remains and the EPA must be challenged to save the nation from the loss of the energy it needs to function. It must be challenged to unleash the huge economic benefits of energy resources—coal, oil, and natural gas—that can reverse our present economic decline. The latest outrage is the MACT rule—an acronym for “maximum achievable control technology” intended...

A rider attached to the omnibus spending bill that will keep the government running through September 30 of next year contains language that would prevent the EPA from enforcing the ban on incandescent light bulbs. But this is only a short respite, as this Politico article explains: DOE's light bulb rules - authorized under a 2007 energy law authored signed by President George W. Bush - would start going into effect Jan. 1. The rider will prevent DOE from implementing the rules through Sept. 30. But Democrats said they could claim a "compromise" by adding language to the omnibus that...

Congressional negotiators struck a deal Thursday that overturns the new rules that were to have banned sales of traditional incandescent light bulbs beginning next year.That agreement is tucked inside the massive 1,200-page spending bill that funds the government through the rest of this fiscal year, and which both houses of Congress will vote on Friday. Mr. Obama is expected to sign the bill, which heads off a looming government shutdown.Congressional Republicans dropped almost all of the policy restrictions they tried to attach to the bill, but won inclusion of the light bulb provision, which prevents the Obama administration from carrying...

Compact fluorescent lamps, or CFLs, have been counted on to light the way to a more energy-efficient future. Compared to traditional incandescent bulbs, which will gradually be phased out starting in January, CFLs use about a fifth the power and have a life six to 10 times as great. However, since the U.S. Consumer Product Safety Commission launched its online safety complaints database in March, there have been 34 reports made by people about CFLs that emitted smoke or a burning odor and four reports of the devices catching fire. As perspective, though, 272 million CFLs were sold in 2009...

Last week the Environmental Protection Agency issued emission standards tightening the rules surrounding the output of mercury and other harmful pollutants. These standards will have the practical effect of making natural gas relatively more attractive than coal for electricity generation since coal-burning plants require the installation of expensive “scrubbers” to clean the emissions they generate. Converting older plants to operate more cleanly often fails to make economic sense and as a result new power plants are increasingly burning natural gas. The Wall Street Journal noted this in an article on Friday. .. But the longer term outlook is increasingly positive....

The Environmental Protection Agency will unveil highly-anticipated regulations on Wednesday aimed at curbing mercury and other toxic air pollutants from power plants. The agency said Tuesday that EPA Administrator Lisa Jackson will make a “significant Clean Air Act announcement” Wednesday at the Children’s National Medical Center in Washington DC. A source closely following the issue confirmed to The Hill that the agency will unveil the final mercury and air toxics standards. Jackson will be joined at the event Wednesday afternoon by public health experts and industry representatives, EPA said. But the agency did not name the officials. The long-delayed...

Every day, Care2 members are my inspiration to tackle challenges. You have shown that when we all band together to create change, we can accomplish amazing things. Over the years I've asked you to take on huge issues, and today I am asking you to take on one of the world's biggest problems -- dirty coal energy that poisons the environment, and us. My children are healthy, which I am grateful for every day. But those of us who live near coal plants or down-stream from a waste site may not be so fortunate. Just because of the food we...

Is a giant, cloaked spaceship orbiting around Mercury? That's been the speculation from some corners aftera camera onboard NASA's STEREO spacecraft caught a wave of electronically charged material shooting out from the sun and hitting Mercury. Theorists have seized on the images captured from the "coronal mass ejection" (CME) last week as suggestive of alien life hanging out in our own cosmic backyard. Specifically, the solar flare washing over Mercury appears to hit another object of comparable size. "It's cylindrical on either side and has a shape in the middle. It definitely looks like a ship to me, and very...

Durham Crematorium wants to install turbines in two of its burners, which would use the heat generated during the cremation process to provide the same amount of electricity as would power 1,500 televisions. A third burner is to be used to provide heating for the site's chapel and its offices. The scheme would be the first of its kind in the UK but industry experts say that it could be followed by other similar projects. Many crematoria are currently replacing their furnaces, to meet government targets on preventing mercury emissions from escaping into the atmosphere. Up to 16 per cent...

Hot and heavy little Mercury is warming up to NASA's MESSENGER probe and revealing its true planetary colors -- in enhanced-color images. Among the spacecraft's finds are bizarre landforms (shown here in blue) tucked inside impact craters on the planet's surface. David Blewett of the Johns Hopkins University Applied Physics Laboratory and his colleagues report these puzzling scarlike hollows in the Sept. 30 Science, which features seven papers describing the compact world. The pits resemble sunken Swiss cheese holes -- smooth, rimless depressions that vary in size between several meters and a few kilometers across. Irregularly shaped, the clustered hollows...

Mercury's Fading Magnetic Field Fits Creation Model by Brian Thomas, M.S. | Oct. 26, 2011 Planets, including the earth, generate magnetic fields that encompass the space around them. Observations have shown that, like earth's, the planet Mercury's magnetic field is rapidly breaking down, and NASA's Messenger spacecraft confirmed that again earlier this year. If the planets in the solar system are billions of years old, why do these magnetic fields still exist? In 1974 and 1975, the Mariner 10 spacecraft measured Mercury's magnetic field strength with its onboard magnetometer and sent the data to earth. The astronomers analyzing the data...

Explanation: One solar day on a planet is the length of time from noon to noon. A solar day lasts 24 hours on planet Earth. On Mercury a solar day is about 176 Earth days long. And during its first Mercury solar day in orbit the MESSENGER spacecraft has imaged nearly the entire surface of the innermost planet to generate a global monochrome map at 250 meters per pixel resolution and a 1 kilometer per pixel resolution color map. Examples of the maps, mosaics constructed from thousands of images made under uniform lighting conditions, are shown (monochrome at left), both...

Washington, D.C.—Only six months into its Mercury orbit, the tiny MESSENGER spacecraft has shown scientists that Mercury doesn't conform to theory. Its surface material composition differs in important ways from both those of the other terrestrial planets and expectations prior to the MESSENGER mission, calling into question current theories for Mercury's formation. Its magnetic field is unlike any other in the Solar System, and there are huge expanses of volcanic plains surrounding the north polar region of the planet and cover more than 6% of Mercury's surface. These findings and other surprises are revealed in seven papers in a special...

Freddie Mercury Day - on what would have been the Queen singer's 65th birthday - has been celebrated with a new Google doodle on the web giant's homepage. In the animated Google Doodle, Mercury is shown singing on stage in front of screaming fans, sat on a throne wearing a crown and dressed as a woman, and strutting about with a hoover. The accompanying video, over 90 seconds long, is set to 1978 Queen hit Don't Stop Me Now. Queen guitarist Brian May, writing on a special Google blog, said: "Freddie would have been 65 this year, and even though...

Researchers identify 26 past scares analogous to the global warming alarm.Polls show that roughly one person in two is concerned about manmade global warming. Why? Because vivid, alarming forecasts, even those based on weak foundations, are persuasive. For a while at least.We’ve seen this many times before. Take the alarm over mercury in fish: in 2004, an Environmental Protection Agency employee warned that 630,000 babies per year were born at risk of brain and nervous system damage due to “unsafe” levels of mercury in their mothers’ blood. Expectant mothers were discouraged from eating fish.Japan consumes a lot of fish, and...

In what critics call a classic case of the government working at cross purposes, Washington is forcing residents across the country to install mercury lighting inside their homes while phasing out mercury lighting outside homes to protect the environment. Yes, you read that right. In 2005, Congress passed a law banning mercury vapor streetlights – two years before it banned incandescent light bulbs in favor of mercury vapor compact florescent bulbs. Under the Energy Policy Act, signed by President Bush in August 2005, manufacturers cannot make or import ballasts for mercury vapor lights after Jan. 1, 2008. According to the...

With its traffic circles and tree-lined squares, America’s capital sometimes resembles a magical, otherworldly place. Maybe that’s why so many who govern here think they can wave their legislative wands and unleash beauty — free of costs and complications. Of course, reality rarely cooperates. Consider Washington’s still-unfolding ban on Thomas Alva Edison’s incandescent light bulb. What the Wizard of Menlo Park, N.J., required 10,000 experiments to perfect, Brooks Brothers socialist George W. Bush needed just one signature to make anathema. If the law is left unchallenged, Jan. 1, 2012, will bring stricter standards that Congress designed in 2007 to eliminate...

Explanation: Now imaging inner planet Mercury from orbit, the MESSENGER spacecraft wide angle camera has returned this impressive color view of Degas Crater, with a full resolution of 90 meters per pixel. Named for the impressionist painter, the 52 kilometer diameter crater is also shown in an inset context image from the Mariner 10 flyby mission in the mid 1970s. In MESSENGER's view, the crater floor is seen to be filled with an intricate series of cracks, formed as the molten surface resulting from the impact cooled and contracted. Starkly bright, patchy deposits, suggesting compositional differences and freshly exposed material,...

Explanation: The robotic MESSENGER spacecraft recently completed over 100 orbits of Mercury. Messenger's cameras have recorded detailed pictures utilizing eight different colors across visible and near infrared light, exploring the surface composition and looking for clues to the history and evolution of the solar system's innermost planet. This sharp image combines three of the MESSENGER wide angle camera's colors, but in exaggerated fashion. Otherwise, to the unaided human eye, Mercury's surface colors would appear comparatively muted. The image is about 1,000 kilometers across and features as small as a single kilometer are discernible at the original resolution. Today, the Messenger...

By WILLIE SOON AND PAUL DRIESSEN The Environmental Protection Agency recently issued 946 pages of new rules requiring that U.S. power plants sharply reduce their (already low) emissions of mercury and other air pollutants. EPA Administrator Lisa Jackson claims that while the regulations will cost electricity producers $10.9 billion annually, they will save 17,000 lives and generate up to $140 billion in health benefits. There is no factual basis for these assertions. To build its case against mercury, the EPA systematically ignored evidence and clinical studies that contradict its regulatory agenda, which is to punish hydrocarbon use. Mercury has always...

Vt. governor to sign mercury lamp recycling billMay 19, 2011 MONTPELIER, Vt.—Vermont Gov. Peter Shumlin is going to signed a bill calling on manufacturers of light bulbs containing mercury to set up and pay for a recycling program for the bulbs. When Shumlin signs the bill Thursday, Vermont will become the third state in the country -- behind Maine and Washington -- to pass what's called a producer responsibility law for mercury-containing products. Lamps containing mercury, including compact fluorescent bulbs, are praised for saving energy. But mercury is a known nerve poison and is a cause of concern when released...

This is an image of Mercury's tail obtained from combining a full day of data from a camera aboard the STEREO-A spacecraft. The reflected sunlight off the planet's surface results in a type of over-exposure that causes Mercury to appear much larger than its actual size. The tail-like structure extending anti-sunward from the planet is visible over several days and spans an angular size exceeding that of a full Moon in the night sky.

First, the bad news: the inner solar system is unstable. Given enough time, Jupiter's gravity could yank Mercury out of its present orbit. Two new computer simulations of long-term planetary motion — one by Jacques Laskar (Paris Observatory), the other by Konstantin Batygin and Gregory Laughlin (University of California, Santa Cruz) — have both reached the same disturbing conclusion. Says Laughlin, "The solar system isn't as stable as we'd thought." Both teams have found that Jupiter's gravity can increase Mercury's orbital eccentricity over time. Mercury's path around the Sun is already nearly as elliptical as Pluto's. But Jupiter can make...
