Most people by now are familiar with the narrative that our planet faces a dire crisis due to rising temperatures.In January 2023, former Vice President Al Gore provided a graphic depiction during a World Economic Forum summit, informing attendees that greenhouse gas (GHG) emissions are “now trapping as much extra heat as would be released by 600,000 Hiroshima-class atomic bombs exploding every single day on the Earth.“That’s what’s boiling the oceans, creating these atmospheric rivers, and the rain bombs, and sucking the moisture out of the land, and creating the droughts, and melting the ice, and raising the sea level,...

Voyager 1 is once again returning data from two of four science instruments onboard. Things are looking better for one of NASA’s longest running deep space missions. After a several-month period of problems, engineers have announced that the Voyager 1 spacecraft is not only back online but also transmitting useful data from two of four science instruments. Work is now underway to bring the remaining two instruments up to operational status. Problems began last November, when Voyager 1 suddenly began sending a repeating gibberish signal instead of the science and engineering data it typically sends. Troubleshooting on the 46-year-old spacecraft...

Gliese 12 b is a newly discovered rocky exoplanet, between Earth and Venus in size. It orbits a red dwarf star 40 light-years away..."Transiting" means this world passes in front of its star from our earthly perspective. That fact makes it possible to observe with TESS, whose full name is the Transiting Exoplanet Survey Satellite...The uncertainties about Gliese 12 b center on its possible atmopshere. If it doesn't have an atmosphere, computer models indicate its average surface temperature are slightly warmer than Earthlike, with an average temperature of only around 107 degrees Fahrenheit (42 degrees Celsius). That's in contrast to...

Some store-bought chocolate desserts may contain dangerous chemicals that could damage your DNA and cause cancer, researchers warn. Scientists found that popular treats like crepes, waffles and cakes contained high levels of carcinogens released during the manufacturing process. These compounds are created when cocoa beans are roasted to help give desserts their chocolatey taste during preparation. The researchers warn they may be evading detection because they are not ingredients intentionally added to the products. The researchers from the Louvain Institute of Biomolecular Science and Technology (IBST) in Belgium said that molecules, called α,β-unsaturated carbonyls, form while roasting cocoa beans and...

Proving that unpaid anonymous review is worth every cent, the 217 year old Wiley science publisher “peer reviewed” 11,300 papers that were fake, and didn’t even notice. It’s not just a scam, it’s an industry. Naked “gobbledygook sandwiches” got past peer review, and the expert reviewers didn’t so much as blink.Big Government and Big Money has captured science and strangled it. The more money they pour in, the worse it gets. John Wiley and Sons is a US $2 billion dollar machine, but they got used by criminal gangs to launder fake “science” as something real.Things are so bad, fake...

A bright green fireball illuminated the night sky over Montana, U.S., at approximately 05:45 UTC on May 21, 2024 (23:45 LT, May 20). The American Meteor Society (AMS) received 65 reports from users in Idaho, Montana, Nevada, Oregon, Utah, and Washington, U.S., as well as in Alberta, Canada. This event follows an exceptionally bright meteor over Spain and Portugal on May 18. The meteor was described as unreal, massive, and a once-in-a-lifetime event. “That’s crazy! Mad props to the person that was able to get this footage,” one eyewitness wrote on X.

In 5,259 BC, our planet was bombarded with a shower of highly energetic particles resulting from a rare cosmic event of exceptional magnitude. Initially revealed through the discovery of carbon isotopes measured in ancient tree ring data, the event produced a roughly two percent increase in atmospheric Carbon-14 (14C), making it one of the strongest events of its kind known to scientists...The breakthrough relied on the combination of annual growth ring measurements with the measurable spike in cosmogenic radiocarbon that occurred during the 5259 BC event. This allowed them to establish a chronological reference point for producing accurate dates for...

Two dwarf galaxies (top and bottom) orbit the much larger Andromeda galaxy. DAVID DAYAG/WIKIMEDIA COMMONS ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When astronomers fret about the “missing satellites problem,” they’re not talking about spacecraft in Earth orbit. Their problem is much bigger: For decades, far fewer dwarf galaxies have been seen orbiting the Milky Way and other large galaxies than predicted by models of galaxy formation. But now, two groups of astronomers have found evidence for not just a sufficient number of satellite galaxies to satisfy the simulations—but too many. “Maybe we’ve oversolved the problem,” says Marcel Pawlowski, an astronomer at the Leibniz Institute for...

Scientists using the SPECULOOS (Search for Planets EClipsing ULtra-cOOl Stars) telescope network have reported the discovery of an Earth-sized planet orbiting the most common star type in the galaxy a mere 55 light years away. Given that the farthest star ever spotted by human scientists lies over 9 billion light-years from Earth, this newly discovered rocky world is one of the closest such space bodies ever spotted. Dubbed SPECULOOS-3 b, the planet orbits an ultracool red dwarf star, the most common star in the Milky Way galaxy. This type of star can live 100 times longer than our Sun, making...

A groundbreaking new pulsed plasma propulsion system could soon enable faster and safer crewed missions to planets like Mars, according to a leading developer of novel technologies aimed at advancing the next stages of human space exploration. Scottsdale, Arizona-based space technology developer Howe Industries recently announced that its Pulsed Plasma Rocket (PPR) could represent a game-changer in advanced propulsion for space travel, allowing crewed missions to significantly reduce the travel time required to reach Mars. According to current timelines, NASA aims to send the first crewed missions to Mars within the next two decades using habitat-like spacecraft paired with hybrid...

Why is the warm gas-giant exoplanet WASP-107 b so puffy? Two independent teams of researchers have an answer. Data collected using NASA’s James Webb Space Telescope, combined with prior observations from NASA’s Hubble Space Telescope, show surprisingly little methane (CH4) in the planet’s atmosphere, indicating that the interior of WASP-107 b must be significantly hotter and the core much more massive than previously estimated. The unexpectedly high temperature is thought to be a result of tidal heating caused by the planet’s slightly non-circular orbit, and can explain how WASP-107 b can be so inflated without resorting to extreme theories of...

Kelsey ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Featured in this new image from the NASA/ESA Hubble Space Telescope is a nearly edge-on view of the lenticular galaxy NGC 4753. Lenticular galaxies have an elliptical shape and ill-defined spiral arms. This image is the object's sharpest view to date, showcasing Hubble’s incredible resolving power and ability to reveal complex dust structures. NGC 4753 resides around 60 million light-years from Earth in the constellation Virgo and was first discovered by the astronomer William Herschel in 1784. It...

Nuclear power could be a game-changer for energy affordability, grid reliability, and carbon reduction. However, it's been stifled for decades based on one deeply flawed scientific model: the linear no-threshold (LNT) model. The theory underlying this model suggests that any exposure to ionizing radiation, no matter how small, increases cancer risks and that risks rise in a linear way with exposure levels. It's not true. The roots of LNT's dominance are more political than scientific. Its influence traces back to Hermann Muller, a geneticist and 1946 Nobel Prize winner. Muller's research in the 1920s and '30s claimed to show that...

A survey of five million distant solar systems, aided by "neural network" algorithms, has discovered 60 stars that appear to be surrounded by giant alien power plants...Ever since theoretical physicist Freeman Dyson first proposed the idea at Princeton in 1960, astrophysicists have speculated that advanced extraterrestrials might have constructed massive solar energy collectors around one star or more.

The celestial wonders of April's solar eclipse and the mesmerizing dance of last weekend's aurora borealis captivated millions, yet the cosmos has an even more elusive spectacle in store. Before the year's end, the night sky will unveil an astronomical phenomenon so extraordinary that it eclipses the rarity of both these events combined. A blazingly bright event known as a nova, a light show that happens approximately once every 80 years, is expected to be visible in the coming months. "This could be a once-in-a-lifetime viewing opportunity," NASA said. An animation showing a nova of a white dwarf that is...

Around a star in our Milky Way galaxy, astronomers have discovered an extremely low-density planet that is as light as cotton candy. The new planet, named WASP-193b, appears to dwarf Jupiter in size, yet it is a fraction of its density. CREDIT: K. Ivanov ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ A team of astronomers from the Massachusetts Institute of Technology (MIT) say they have discovered a distant planet that they can’t explain with current planet evolutionary theories. The newly discovered WASP-193b is a gas giant 50 percent larger than Jupiter, the largest gas giant in our solar system. However, it is only one-tenth as dense,...

Explanation: A familiar sight from Georgia, USA, the Moon sets near the western horizon in this rural night skyscape. Captured on May 10 before local midnight, the image overexposes the Moon's bright waxing crescent at left in the frame. A long irrigation rig stretches across farmland about 15 miles north of the city of Bainbridge. Shimmering curtains of aurora shine across the starry sky, definitely an unfamiliar sight for southern Georgia nights. Last weekend, extreme geomagnetic storms triggered by the recent intense activity from solar active region AR 3664 brought epic displays of aurora, usually seen closer to the poles,...

MIT astronomers discovered three of the oldest stars in the universe, and they live in our own galactic neighborhood. The stars are in the Milky Way’s “halo” — the cloud of stars that envelopes the main galactic disk — and they appear to have formed between 12 and 13 billion years ago, when the very first galaxies were taking shape. Credit: Serge Brunier; NASA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Astronomers discovered three ancient stars circling the Milky Way’s halo, formed 12-13 billion years ago. MIT researchers have discovered three of the oldest stars in the universe, and they happen to live in our own...

A solar flare measured at X8.7 on the strength scale just emerged from AR 3664, the sunspot region responsible for last weekend's solar storms that sparked vivid auroras.That's the most powerful solar flare of the current cycle, absolutely the most powerful since 2017, and comfortably within the top 20 solar flares ever measured.As AR 3664 made its way toward the edge of the Sun's disk, it wasn't just the X8.7 flare on May 14 that erupted from the solar limb. On May 15, an X3.4 flare followed suit, suggesting that the giant sunspot region is going to continue its party...

Just two weeks ago, the European Space Agency announced the discovery of a new black hole, the heaviest on the Milky Way, 33 times bigger than the Sun and 2,000 light years from Earth. Tel Aviv University’s Prof. Tsevi Mazeh, who was recently awarded the Israel Prize in physics, is among those responsible for the European Gaia spacecraft’s discovery. But if you ask him how excited he was that week, in which he both learned of his Israel prize award and his research on the new black was published, he’ll swiftly answer “The Israel prize wins bigtime.” “I cried a...
