    A team of European researchers says that hundreds of thousands of meteorites, which may provide valuable information about the dawn of life on Earth, are disappearing from Antarctica at an alarming rate. Based on their research, the scientists behind the alarming findings say that as many as three-quarters of the approximately 300,000-800,000 meteorites resting on the surface of the Antarctic ice sheet could be lost by 2050. Published in the journal Nature Climate Change, the research says the culprit behind the wholesale disappearance is the steady rise in global temperature. “For every tenth of a degree of increase in global...

    Computer simulations reveal that the close flyby of Apophis, the "God of Chaos" asteroid, in 2029 still poses no risk to Earth, even when a worrying, previously unrecognized factor is taken into account. There is almost zero chance that the infamous city-killer asteroid "Apophis" will hit Earth when it zips closely past our planet in 2029 — even when a previously unconsidered factor is taken into account, a new study shows. Apophis is a peanut-shaped space rock spanning around 1,100 feet (340 meters) across that was left behind by the formation of the solar system around 4.6 billion years ago....

    Astronomers have detected water molecules on the surface of asteroids for the first time, a surprising find given that the space rocks were thought to be “completely dry.” ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Water molecules have been detected on the surface of asteroids for the first time, proving that these remnants from the formation of our solar system aren’t just dried-up space rocks. Astronomers believe that the impact of asteroids crashing into our planet may have helped deliver water and other elements to early Earth, so finding evidence of water on asteroids could support that theory, according to a new study. The data was...

According to the National Academies and their 2023-2032 Planetary Science and Astrobiology Decadal Survey, ground based astronomical radar systems will have a "unique role" to play in planetary defense. There is currently only one system in the world concentrating on these efforts, NASA's Goldstone Solar System Radar, part of the Deep Space Network (DSN). However, a new instrument concept from the National Radio Astronomy Observatory (NRAO) called the next generation RADAR (ngRADAR) system will use the National Science Foundation's Green Bank Telescope...

    Small asteroid hits Earth on January 21, 2024In the late-night hours of January 21, 2024 – 90 minutes before impact over European skies – NASA said a small asteroid would hit Earth’s atmosphere. And hit it did. The space rock struck on schedule above an area west of Berlin, Germany. The asteroid was only about 1 meter (3 feet) in diameter. It posed no danger to people on the ground. Yet it’s possible the asteroid might have spread small meteorites over the landscape.

    A very interesting space mission that is at the same time kind of frightening: A NASA spacecraft that recently returned from deep space has been relaunched for a mission to study the "God of Chaos" asteroid as it begins to near Earth's orbit. The agency's spacecraft OSIRIS-REx — now named the OSIRIS-APEX — has been sent off to study the asteroid Apophis' extremely close flyby of Earth in 2029, the likes of which "hasn't happened since the dawn of recorded history," NASA announced. Oh really, an asteroid is making an "extremely close flyby" of our fragile planet in 5ish years?...

    Scientists believe Kamo’oalewa will remain alongside Earth for millions of years. Could a near-Earth asteroid be a piece of the moon? Astronomers from the University of Arizona believe so. In a captivating cosmic discovery, scientists uncovered evidence suggesting that a near-Earth asteroid called Kamo’oalewa might be a fragment of the moon. The finding challenges previous assumptions about the origins of near-Earth asteroids and could have significant implications for our understanding of celestial bodies close to our planet.

  • A prehistoric cosmic airburst preceded the advent of agriculture in the Levant

    10/06/2023 4:16:13 AM PDT · by FarCenter · 27 replies
    Agriculture in Syria started with a bang 12,800 years ago as a fragmented comet slammed into the Earth's atmosphere. The explosion and subsequent environmental changes forced hunter-gatherers in the prehistoric settlement of Abu Hureyra to adopt agricultural practices to boost their chances for survival. That's the assertion made by an international group of scientists in one of four related research papers, all appearing in the journal Science Open: Airbursts and Cratering Impacts. The papers are the latest results in the investigation of the Younger Dryas Impact Hypothesis, the idea that an anomalous cooling of the Earth almost 13 millennia ago...

    oom At 12:37 a.m. EDT (10:37 a.m. MDT), a helicopter gently placed NASA’s OSIRIS-REx sample capsule, attached to the end of a 100-foot cable, on the ground outside a hangar on the Department of Defense’s Utah Test and Training Range. Two technicians on the ground helped guide the capsule down. Once the helicopter line was detached and the helicopter had departed, the clean room team removed the capsule from its metal transport cradle. They loaded the capsule onto a cart and wheeled it into the hangar where a temporary clean room had been set up. In the hangar, the capsule...

    Geologists have recently discovered two alien minerals unknown to Earth in a meteorite in Somalia. A small, 2.5 ounce (70-gram) fragment of the fifteen thousand kilogram fallen comet known as El Ali revealed the alien ore. Scientists stumbled upon the unknown mineral in the meteorite while sampling a slice. It was only after analyzing the segment in a lab that they realized they had discovered something completely new. Alien minerals in El Ali meteorite Researchers, scientists, and geologists are excited by the revelation, as it might help them understand more about asteroids and how they form as well as the...

    Early morning on Sunday, Sept. 24, the OSIRIS-REx spacecraft’s sample capsule will come face-to-face with Earth’s atmosphere for the first time since the mission’s 2016 launch. On board are an estimated 8.8 ounces, or 250 grams, of rocky material collected from the surface of Bennu in 2020 – NASA’s first asteroid sample and the largest ever collected in space. When it approaches Earth, the OSIRIS-REx spacecraft won’t slow down as it makes its sample drop-off. Instead, when it reaches 63,000 miles (or 102,000 kilometers) above Earth’s surface – about one-third the distance from Earth to the Moon – a message...

    Explanation: The OSIRIS-REx spacecraft's arm reached out and touched asteroid 101955 Bennu on October 20, 2020, after a careful approach to the small, near-Earth asteroid's boulder-strewn surface. Dubbed a Touch-And-Go (TAG) sampling event, the 30 centimeter wide sampling head (TAGSAM) appears to crush some of the rocks in this close-up recorded by the spacecraft's SamCam. The image was snapped just after surface contact some 321 million kilometers from planet Earth. One second later, the spacecraft fired nitrogen gas from a bottle intended to blow a substantial amount of Bennu's regolith into the sampling head, collecting the loose surface material. And...

    When the OSIRIS-REx spacecraft swings by Earth on Sunday, it is expected to deliver a rare cosmic gift: a pristine sample collected from the near-Earth asteroid Bennu If all goes according to plan, the spacecraft will release a capsule containing an estimated 8.8 ounces of asteroid rocks and soil from space toward a landing zone in the Utah desert. NASA will provide a live stream of the sample delivery beginning at 10 a.m. ET Sunday. The capsule is expected to enter Earth’s atmosphere at 10:42 a.m. ET, traveling about 27,650 miles per hour (44,498 kilometers per hour). It will land...

    NASA scientists have predicted there is a chance that a massive asteroid they have been tracking could smash into earth in the year 2182, potentially devastating an area the size of Texas. Bennu, a Near-Earth Object (NEO), orbits the earth roughly every six years and has been on the space agency’s radar since 1999 when it was first discovered. There have been three close encounters involving Bennu in 1999, 2005, and 2011, scientists said. On September 25, 2135, Bennu will make a close fly-by past Earth and has a miniscule chance through a pass through a “gravitational keyhole” that would...

    An asteroid hit during NASA’s successful DART mission in Sept. 2022 is acting mysteriously, and it’s not clear why. Back in 2022, NASA tested their DART mission to see if we’re capable of altering the trajectory of an asteroid. To do so, NASA crashed a probe into the target, Dimorphos, and successfully changed its trajectory. Dimorphos’s orbit around the larger asteroid, Didymos, was shortened by 33 minutes within weeks of the impact. But then, something else started happening. High school teacher Jonathan Swift at California’s Thatcher School and his students used an observatory at the institution to keep track of...
