    Rattled outdoor furniture, frightened cats. We heard reports from several readers about the mysterious booms and flashes of light early this morning over Puget Sound: "I was watching late night TV when at exactly 2:42 p.m. I saw the sky light up like a nuclear bomb had exploded. The entire sky and my whole yard glowed a luminous red color. I went outside to investigate and could hear a loud rumbling noise."

    On Sunday, Dec. 16, the comet known as 46P/Wirtanen will make one of the 10 closest comet flybys of Earth in 70 years, and you may even be able to see it without a telescope. Although the approach will be a distant 7.1 million miles (11.4 million kilometers, or 30 lunar distances) from Earth, it's still a fairly rare opportunity. "This will be the closest comet Wirtanen has come to Earth for centuries and the closest it will come to Earth for centuries," said Paul Chodas, manager of the Center for Near-Earth Object Studies at NASA's Jet Propulsion Laboratory in...

    A new kind of giant dinosaur has been described in Russia. Dubbed Volgatitan, the herbivore belonged to a family of long-necked dinosaurs called sauropods. It weighed 17 tons and walked the earth 200 million to 65 million years ago. The enormous dinosaur was identified from seven of its vertebrae, which had been stuck in a cliff for 130 million years until they were discovered on the banks of the Volga river near Ulyanovsk in 1982. ..." The bones sat for 20 years until they were re-examined by Averianov. ..." “[After] checking the literature when I returned home, [I] confirmed that...
  • Gravity variations predict earthquake behavior

    08/04/2003 12:08:17 AM PDT · by LibWhacker · 12 replies · 155+ views
    In trying to predict where earthquakes will occur, few people would think to look at Earth's gravity field. What does the force that causes objects to fall to the ground and the moon to orbit around the earth have to do with the unpredictable ground trembling of an earthquake? Now, researchers at the California Institute of Technology have found that within subduction zones, the regions where one of the earth's plates slips below another, areas where the attraction due to gravity is relatively high are less likely to experience large earthquakes than areas where the gravitational force is relatively low....

    'Potato' Earth's deep secrets By Jonathan Amos BBC News Online science staff It is a map the like of which you have probably never seen before. Gravity highs are marked red; gravity lows are blue The sweep of colours shows minute variations in the Earth's gravitational field. If you were to fly over the red areas, you would be tugged ever so slightly downwards; the blues mark regions where the planet's attraction is much weaker. These gravity anomalies, as they are known, are imperceptible to the human senses, and so the scientists have wrapped the data on to a sphere...

    Astronomy Picture of the Day 2001 November 13 A Gravity Map of Earth Credit: JPL, NASA Explanation: Is gravity the same over the surface of the Earth? No -- it turns out that in some places you will feel slightly heavier than others. The above relief map shows in exaggerated highs and lows where the gravitational field of Earth is relatively strong and weak. A low spot can be seen just off the coast of India, while a relative high occurs in the South Pacific Ocean. The cause of these irregularities is unknown since present surface features do not ...

    The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We're doing it right now, aren't we? We are all traveling into the future one second at a time. But that was not what you were thinking. Can we travel much further into the future? Absolutely. If we could travel close to the speed of light, or in the proximity of a black hole, time would slow down enabling us to travel arbitrarily far into the future. The really interesting question is whether we can travel...

    At first glance it looks like a potato-shaped asteroid flying through space. But this multi-coloured image is actually the Earth - and shows how gravity varies on different parts of the globe. The images were unveiled today by the team behind the GOCE satellite at a conference in Munich and are the most accurate ever released. The 'geoid' map, as it is known, is used to illustrate how oceans would look in the absence of currents or tides. The bright yellow colours show gravity at its strongest, while it is at its weakest in the blue areas. There appears to...
  • Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos

    Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses 'negative mass." If you were to push a negative mass, it would accelerate towards you. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago. Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark matter and dark energy are like physically. We only know about them because of the gravitational effects they...

    Stargazers, get ready to bundle up as you catch one of the best meteor shows of the year — the Geminid meteor shower. A sprinkle of stars will be visible in the night's sky this week as the winter meteor shower makes its annual appearance. The meteor shower, which contains debris from 3200 Phaethon, is expected to peak Thursday night into Friday morning, shooting anywhere between 60 to 120 meteors per hour. The space rocks will zoom by, hitting Earth at around 22 miles per second, according to the American Meteor Society (AMS). ..."

    When it comes to alarming projections of global warming-induced sea level rise, veteran climate scientist Judith Curry says people need to cool it. “Projections of extreme, alarming impacts are very weakly justified to borderline impossible,” Curry told The Daily Caller News Foundation. Curry’s latest research, put together for clients of her consulting company near the end of November, looks in detail at projections of sea level rise. Curry’s ultimate conclusion: “Some of the worst-case scenarios strain credulity.” “With regards to 21st century climate projections, we are dealing with deep uncertainty, and we should not be basing our policies based on...

    On December 1, 2018, NASA’s InSight lander captured a haunting low rumble caused by vibrations from the Martian wind, estimated to be blowing between 10 to 15 mph (5-7 m/sec) from northwest to southeast. The wind was consistent with the direction of dust devil streaks in the landing area, which were observed from orbit. “Capturing this audio was an unplanned treat. But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves,” said InSight principal investigator Dr. Bruce Banerdt, a researcher at NASA’s Jet Propulsion Laboratory.The vibrations...

    NASA’s spacecraft that landed on Mars on Monday has beamed back its first clear photo of the desolate Red Planet. “There’s a quiet beauty here. Looking forward to exploring my new home,” NASA tweeted late Monday, hours after its new InSight lander touched down. The image came after the rover had earlier sent back a somewhat blurry photo. The space agency said that in the interim, the spacecraft had opened its solar panels, which allowed it to recharge its batteries for the mission.

    NASA's InSight Mars lander is scheduled to touch down on the Red Planet tomorrow afternoon (Nov. 26), and mission team members and agency officials are understandably nervous about the make-or-break moment. … The difficulty for landed missions stems chiefly from the fact that Mars features both a relatively strong gravitational pull and a wispy atmosphere, which is just 1 percent as thick as that of Earth, said Tom Hoffman, InSight project manager at JPL. So, approaching spacecraft get accelerated to high speeds and then have a hard time dissipating enough energy to slow down before landing, he explained during today's...

    The InSight (or "Interior Exploration using Seismic Investigations, Geodesy and Heat Transport") lander will push through Mars' thin atmosphere using small rockets, deploy parachutes to slow its fall to the surface, and then use retro rockets to finally stick the landing. It will take about 6 minutes from the time the lander reaches the Martian atmosphere until it touches down on the surface of the Red Planet. (Of course, this is if everything goes according to plan: For example, the lander may face dust storms in the northern hemisphere where it's aiming to land. According to NASA, these autumn Martian...

    All systems are go for landing on Mars on Nov. 26, NASA personnel affiliated with the InSight mission confirmed during a pair of news conferences held today (Nov. 21). As of that news conference, the spacecraft had traveled about 295 million miles (475 million kilometers) of the 301 million miles (484 million km) that will make up its total journey. But one of the most serious hurdles remains, the entry, descent and landing process, which will begin at about 3 p.m. EST (2000 GMT) on Monday (Nov. 26).
