    Videos of the event show a spectacular light with green and purplish hues flying across the sky for just a few seconds at around 2:30 a.m. local time, before the light fizzles out. The impact of what was likely a small asteroid colliding with our atmosphere was picked up by a few of the infrasound monitoring stations set up around the world and overseen by the Comprehensive Nuclear-Test-Ban Treaty Organization. The International Meteor Organization reports that the meteoroid was visible from a large part of Japan's Kanto region. The IMO estimates the space rock could've been around 5 feet (1.6...

    This latest flyover video from the European Space Agency's Mars Express spacecraft, provides a stunning view of one of Mars' most eye-popping craters. This movie was created using an imagery from Mars Express' High Resolution Stereo Camera (HRSC). The images are normally taken looking straight down (nadir), and the video combines topography information from the stereo channels of HRSC to generate a three-dimensional landscape, which was then recorded from different perspectives, as with a movie camera, to render the flight shown in the video. Korolev Crater is 82 kilometers (50 miles) across and at least 2 km (1.25 miles) deep....

    (CNN)The fastest-growing black hole in the universe is 34 billion times the mass of our sun and feasts on a meal the equivalent of our sun each day, according to a new study. This massive, hungry black hole was first identified and studied by researchers in May 2018. Previously, they believed it consumed the mass equivalent to our sun every two days. Now, they have a better understanding of this monster black hole and its gluttonous behavior. The study published Wednesday in the journal Monthly Notices of the Royal Astronomical Society. The black hole is known as J2157 and exists...

    Explanation: Sharp telescopic views of NGC 3628 show a puffy galactic disk divided by dark dust lanes. Of course, this deep portrait of the magnificent, edge-on spiral galaxy puts some astronomers in mind of its popular moniker, the Hamburger Galaxy. It also reveals a small galaxy nearby, likely a satellite of NGC 3628, and a faint but extensive tidal tail. The drawn out tail stretches for about 300,000 light-years, even beyond the right edge of the wide frame. NGC 3628 shares its neighborhood in the local universe with two other large spirals M65 and M66 in a grouping otherwise known...

    In a recent interview, Dr. John Ioannidis had a harsh assessment of modelers who predicted as many as 40 million people would die and the US healthcare system would be overrun because of COVID-19. =========================================================================== Dr. John Ioannidis became a world-leading scientist by exposing bad science. But the COVID-19 pandemic could prove to be his biggest challenge yet. Ioannidis, the C.F. Rehnborg Chair in Disease Prevention at Stanford University, has come under fire in recent months for his opposition to state-ordered lockdowns, which he says could cause social harms well beyond their presumed benefits. But he doesn’t appear to be...

    A giant star which was under the observation of astronomers for over ten years has suddenly vanished. The star in question was located in a dwarf galaxy 75 million light-years away, and was one of the largest stars in the known universe. The star, which was 2.5 times brighter than the Sun, left no trace behind The star was located in a very far off galaxy, making its detection and observation very difficult. The astronomers observed it based on its signature, which was picked up and then analysed, instead of a direct observation. A highly unstable blue star, researchers picked...

    On the night of July 4, the full moon will pass through part of Earth’s shadow, creating a lunar eclipse that will be visible across North America and South America. This will be the first lunar eclipse visible from this part of the world since 2019. People in some places in Africa and western Europe will also be able to see part of the eclipse. The eclipse will be the perfect celestial event for those across the United States staying up late after Independence Day fireworks, as long as clouds don’t interfere. In a penumbral lunar eclipse, the moon passes...

    Surely, Timothy Litzenburg is a wealthy man. As one of the lead plaintiffs' attorneys suing Monsanto over the alleged (but factually incorrect) claim that its product Roundup (glyphosate) causes cancer, he likely has had several nice paydays in recent years as the company has been slammed with one jackpot verdict after another. Lawsuits have cost its parent company, Bayer, billions of dollars. The trouble with money, however, is that no matter how much you have, you never really have enough. You always want more. Litzenburg wanted more, too, and he knew just how to do it. After seeing how easy...
  • Bright Planetary Nebula NGC 7027 from Hubble (Astronomy Picture of the Day)

    APOD.NASA ^ | 30 Jun, 2020 | NASA/Joel Kastner
    Explanation: What created this unusual planetary nebula? NGC 7027 is one of the smallest, brightest, and most unusually shaped planetary nebulas known. Given its expansion rate, NGC 7027 first started expanding, as visible from Earth, about 600 years ago. For much of its history, the planetary nebula has been expelling shells, as seen in blue in the featured image. In modern times, though, for reasons unknown, it began ejecting gas and dust (seen in red) in specific directions that created a new pattern that seems to have four corners. These shells and patterns have been mapped in impressive detail by...

    Meanwhile, the Doppler discovery of extrasolar planets orbiting very close to their parent stars has raised a different problem. Many of the planets are so close to their stars (<0.1 AU), and so hot, that they cannot be supposed to have formed where we now observe them. By inference, they could have formed at larger distances (several AU) and then migrated inwards. What would cause this inward migration? As with the solar system case, the root cause may be an exchange of angular momentum with material surrounding the planets at their formation. In particular, if the extrasolar planets formed in...

    Researchers say life-bearing planets may exist in vast numbers in the space between stars in the Milky WayA few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. So argues an international team of scientists led by Professor Chandra Wickramasinghe, Director of the Buckingham Centre for Astrobiology at the University of Buckingham, UK. Their findings are published online in the Springer journal Astrophysics and Space Science. The scientists have proposed that these life-bearing planets originated in the early Universe within a few million years of the Big Bang, and that...

    Astronomers used ESO's Very Large Telescope and the Canada-France-Hawaii Telescope to find CFBDSIR2149, a free-floating planet with the mass of Jupiter that seems to wander through space without orbiting around a star like most planets we know do. In addition, the planet is actually relatively close to our solar system, only 100 light-years away, and offers scientists a more intimate setting to study a planet and its atmosphere. This isn't the first time that a free-floating object has been found in space, but the previous discoveries haven't provided scientists with enough information to label the body as a planet. Instead,...

    Scattered about the Milky Way are floating, Jupiter-mass objects, which are likely to be planets wandering around the Galaxy's core instead of orbiting host stars. But these planets aren't rare occurrences in the interstellar sea: the drifters might be nearly twice as numerous as the most common stars. "This is an amazing result, and if it's right, the implications for planet formation are profound," says astronomer Debra Fischer at Yale University in New Haven, Connecticut. To find the wanderers, scientists turned their telescopes towards the Galactic Bulge surrounding the centre of the Milky Way. Using a technique called gravitational microlensing,...

    An international team of astronomers claim to have found free-floating "planets" which do not seem to orbit a star.Writing in Nature, they say they have found 10 Jupiter-sized objects which they could not connect to any solar system. They also believe such objects could be as common as stars are throughout the Milky Way. The objects revealed themselves by bending the light of more distant stars, an effect called "gravitational microlensing".Objects of large enough mass can bend light, as Albert Einstein predicted. If a large object passes in front of a more distant background star, it may act as a...

    An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago—a newborn in planet lifetimes. It was identified from its faint and unique heat signature by the Pan-STARRS 1 (PS1) wide-field survey telescope on Haleakala, Maui. Follow-up observations using other telescopes in Hawaii show that it has properties similar to those of gas-giant planets found orbiting around young stars. And yet PSO...

    Science and “Science” Politicians love to say that they are “following the science.” To hear them talk, you would think they spend hours poring over data and they go where the numbers drive them. If only.The COVID epidemic has brought out politicians’ faux reliance on “science” in spades. As good an example as any is my state, Minnesota, where our governor, Tim Walz, has offered one tribute after another to “science” as he has driven our state off the road and into the ditch with an irrational shutdown that protected all but the vulnerable.When Walz issued his harsh shutdown order,...

    Without warning, a mystery object struck Jupiter on July 19, 2009, leaving a dark bruise the size of the Pacific Ocean. The spot first caught the eye of an amateur astronomer in Australia, and soon, observatories around the world, including NASA’s Hubble Space Telescope, were zeroing in on the unexpected blemish. Astronomers had witnessed this kind of cosmic event before. Similar scars had been left behind during the course of a week in July 1994, when more than 20 pieces of Comet P/Shoemaker-Levy 9 (SL9) plunged into Jupiter’s atmosphere. The 2009 impact occurred during the same week, 15 years later....
