    A composite image showing Comet 12P/Pons-Brook (left) and a model of the Millennium Falcon spaceship from "Star Wars" (right). (Comet Chasers/Faulkes Telescope Project/Las Cumbres Observatory/Reuters/Insider) Astronomers have spotted a "once-in-a-lifetime" comet shaped like the Millennium Falcon – and sky gazers may soon be able to see it for themselves without a telescope. The comet, known as Comet 12P/Pons-Brooks, abruptly brightened 100-fold on July 20 as plumes of debris and ice were blasted off it into space. This gave it a horseshoe shape, which scientists likened to the Millennium Falcon spaceship from "Star Wars." The comet will make its closest approach...

    Tiny spheres of once-molten metal magnetically dredged from the seafloor could be pieces from IM1, a potential interstellar meteor that struck Earth in 2014 Over the past two weeks, I have circumnavigated the globe by land, air and sea. The reason? A kitchen sink–sized chunk of interstellar material that my colleagues and I believe collided with the Earth at 100,000 miles per hour nearly a decade ago. After years of effort, we may have finally found pieces of this elusive object on the bottom of the Pacific Ocean, about a mile beneath the waves. The story began In April 2019,...

    When Suzy Kop entered her father's bedroom on May 8, 2023, she was stunned to find a grapefruit-sized rock next to a big dent on the wooden floor. Upon further investigation, the New Jersey resident saw two holes in the ceiling. It appeared that the stone had struck the floor with such great force that it rebounded and punched a second hole before landing back.
  • The Heaven’s Gate Option: Congressional Democrats Beg Biden to Make Them Constitutional Nonentities

    Below is a slightly modified version of my column in The Hill on the call of Democrat members for Joe Biden to circumvent Congress and simply raise the debt limit unilaterally. It is more than a flawed constitutional theory. It is an abandonment of the core premise of our constitutional system that each branch would jealously protect its own institutional interests and powers. It is reminiscent of when Democrats applauded wildly when Barack Obama told them that he was going to circumvent Congress entirely after it refused to approve his immigration and environmental legislation. They were applauding their own institutional...
  • Scientists Reveal Interstellar Object ‘Oumuamua’ Has Organic Shell

    Observations of the oblong interstellar traveler Oumuamua have revealed an unidentified organic coating on it, igniting scientific and public curiosity alike. After “Oumuamua” was initially spotted by a telescope in Hawaii by the Pan-STARRS project on October 19, experts raced to gather all possible information on it before it passed beyond humanity’s collective reach. But, while they expected to find a comet-like chunk of ice passing by our sun, the object mysteriously failed to leave behind a vapor trail as it grazed our home star. Instead, the still-unidentified chunk of ancient space debris hurtling at 60,000 MPH through our solar...
  • First measurements of 'interstellar comet' [C/2019 Q4 (Borisov)]

    The team used the Osiris instrument at the 10.4m Gran Telescopio Canarias in La Palma, Spain, to obtain visible spectra - measurements of sunlight reflected by Borisov. By studying these spectra, scientists can draw conclusions about its chemical composition, including how it might differ from comets that were "born" around the Sun. "The spectrum is the red side of the comet's total spectrum, so the only thing we can see in the spectrum is the slope," said Miquel Serra Ricart, from the Instituto de Astrofísica de Canarias (IAC) in Tenerife. In coming days, the team will obtain measurements of the...

    It is the first known object to pass through the solar system from outside, but experts have failed to explain where the object, called 'Oumuamua' came from. The mysterious cigar-shaped projectile - formally named the object 1I/2017 U1 - defies description with characteristics resembling both a comet and an asteroid. Oumuamua...spins like a coke bottle and accelerates like a comet, but without the gas jets often seen trailing them. The study’s co-author, Dr. Matthew Knight, an associate research scientist in the University of Maryland Department of Astronomy, said: “The alien spacecraft hypothesis is a fun idea, but … our preference...

    `Oumuamua, pronounced oh-MOO-ah-MOO-ah – is moving away from the sun faster than expected. The Hubble Space Telescope made the discovery, in cooperation with ground-based telescopes... The measured gain in ‘Oumuamua’s speed is tiny, these astronomers said. Plus, our sun is still trying to drag `Oumuamua back; that is, the sun’s gravity is still slowing down the object, though not as fast as predicted by celestial mechanics. Marco Micheli of the European Space Agency led the team that explored several scenarios to explain ‘Oumuamua’s faster-than-predicted speed. The most likely explanation is that `Oumuamua is venting material from its surface due to...

    Nearly six years ago, a space object roughly the size of a football field baffled scientists as it zipped through our solar system. The irregular shape and motion of the object, dubbed ‘Oumuamua, led to one of the most controversial astronomical mysteries, with theories that ranged from asteroid to alien probe. But a study published Wednesday in the journal Nature offers another answer: ‘Oumuamua is a typical comet that expelled gas in an odd way as it traveled through our solar system. “We’ve gone through every weird, crazy, possible theory—ideas that stretch the imagination to match all of these observed...

    First detected on Feb. 27, the asteroid dubbed 2023 DW is estimated to measure about 165 feet (50 meters) in diameter, or roughly the length of an Olympic-size swimming pool. The asteroid is expected to make a very close approach to Earth on Feb. 14, 2046; as of March 8, the European Space Agency's Near-Earth Object Coordination Centre(opens in new tab) predicts a 1-in-625 chance of a direct impact, although those odds are being recalculated daily. "Often when new objects are first discovered, it takes several weeks of data to reduce the uncertainties and adequately predict their orbits years into...

    According to the Minor Planet Center, the comet C/2023 A3 (Tsuchinshan-ATLAS) was discovered on February 22 by the Asteroid Terrestrial-impact Late Alert System (ATLAS) telescope project in South Africa. When astronomers at China's Purple Mountain Observatory found the comet independently on January 9, both observatories are mentioned in the comet's complete name. Skywatchers throughout the world have subsequently seen it in fresh and old photos, with the first discovery being on December 12, 2022, in photographs obtained by a wide-field camera on a telescope at Palomar Observatory in California. Meanwhile, EarthSky reports that C/2023 A3 is currently between Saturn and...

    More than 1500 years ago, a vast culture known as the Hopewell tradition (or Hopewell culture) stretched across what is today the eastern United States. The cause of the culture's decline has long been debated, with war and climate change two of the possibilities, but now a new avenue of inquiry has opened up: debris from a near-Earth comet. Researchers working across 11 different Hopewell archaeological sites covering three states have found unusual concentrations of iridium and platinum in their digging – telltale signs of meteorite fragments. Meanwhile, a charcoal layer in the sediment suggests an intense period of high...

    Explanation: Can you still see the comet? Yes. Even as C/2022 E3 (ZTF) fades, there is still time to see it if you know where and when to look. Geometrically, Comet ZTF has passed its closest to both the Sun and the Earth and is now headed back to the outer Solar System. Its orbit around the Sun has it gliding across the northern sky all month, after passing near Polaris and both the Big and Little Dippers last month. Pictured, Comet ZTF was photographed between the two dippers in late January while sporting an ion tail that extended over...

    The origins of Comet 96P/Machholz (96P) have puzzled scientists for decades since its discovery. It is a four-mile-wide “sungrazer” object with a host of weird properties that suggest it may be an interloper from another star system. For instance, 96P’s composition is extremely unique and its orbit is highly tilted, causing it to pass closer to the Sun than almost any other comet. These features, among others, suggest that 96P may have been rerouted into our solar system by a chance encounter with Jupiter after its voyage across interstellar space. In an ironic twist, however, the comet's interactions with Jupiter...

    Explanation: The current darling of the northern night, Comet C/2022 E3 ZTF is captured in this telescopic image from a dark sky location at June Lake, California. Of course Comet ZTF has been growing brighter in recent days, headed for its closest approach to Earth on February 1. But this view was recorded on January 23, very close to the time planet Earth crossed the orbital plane of long-period Comet ZTF. The comet's broad, whitish dust tail is still curved and fanned out away from the Sun as Comet ZTF sweeps along its orbit. Due to perspective near the orbital...

    C/2022 E3 (ZTF) is set to pass by Earth for the first time since Neanderthals existed 50,000 years ago. Excitement among sky-watchers is building as a comet, not visible since the time of the Neanderthals, is heading towards Earth again. Formally known as C/2022 E3 (ZTF), the comet orbits the sun every 50,000 years and is set to make its closest approach to our planet on February 1, 2023. E3 was discovered in March, but scientists recently snapped the first detailed photo revealing its brighter greenish coma and a yellowy dust tail. While the comet is too dim to see...

    Two billion years ago a meteorite 10km in diameter hit the earth about 100km southwest of Johannesburg, creating an enormous impact crater. This area, near Vredefort in the Free State, is now known as the Vredefort Dome... The meteorite, larger than Table Mountain, caused a thousand-megaton blast of energy. The impact would have vaporised about 70 cubic kilometres of rock - and may have increased the earth's oxygen levels to a degree that made the development of multicellular life possible...
