Preston Dyches, NASA Jet Propulsion Laboratory Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter. Between July 16 and July 22, 1994, space- and Earth-based assets managed by NASA's Jet Propulsion Laboratory in Pasadena, California, joined an armada of other NASA and international telescopes, straining to get a glimpse of the historic event: -...

redOrbit Staff & Wire Reports - Your Universe Online The Moon was most likely formed by a collision between the Earth and a planet-sized object that took place roughly 4.5 billion years ago, a team of German scientists report in research published Friday by the journal Science. According to the Associated Press (AP), the study authors took an in-depth look at moon rocks that had been gathered during the Apollo 11, 12 and 16 missions. They discovered that moon rocks have a different...

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

Permian Mass Extinction May Have Happened In The Blink Of An Eye

April Flowers for redOrbit.com - Your Universe Online Approximately 252 million years ago, the largest mass extinction event in the history of animal life on Earth occurred — wiping out more than 96 percent of marine species and 70 percent of terrestrial species. This included the largest insects known to have inhabited the planet. Scientists have explored many theories to explain the cause of the end-Permian extinction, as it came to be known. Those theories include an asteroid...

[ Watch the Video: Divers Recover Huge Russian Meteorite Fragment ] Lawrence LeBlond for redOrbit.com - Your Universe Online Divers searching Lake Chebarkul in Russia have pulled from the lakebed a massive chunk of the Chelyabinsk meteorite that exploded over the Ural Mountains region earlier this year. On February 15, 2013 a massive meteor entered Earth’s atmosphere, traveling at speeds in excess of 30,000 mph. As it blazed a trail across the early morning sky, many videos caught...

Ancient Mammals Evolution Mass Extinction

Brett Smith for redOrbit.com - Your Universe Online With the continuous expansion of human activity around the world, many species are facing the increasing threat of extinction as their habitats shrink and shift. Yet life on planet Earth has faced even larger extinction threats in the past. A new study int the journal Proceedings of the Royal Society B examines how a group of mammalian relatives called anomodonts coped with a mass extinction event of the prehistoric past as a way to...

Meteorite Fragments From The Tunguska Event

redOrbit Staff & Wire Reports - Your Universe Online A Russian scientist has reportedly found meteorite or asteroid fragments potentially linked to a mysterious explosion that took place over Siberia more than 100 years ago. The Tunguska Event, as it is called, took place in June 1908. It featured a blast that was one thousand times more powerful than the Hiroshima atomic bomb and decimated approximately 80 million trees over an 800 square mile area, but resulted in only a single...

Mass Extinction Made Space Dinosaur Forerunners

April Flowers for redOrbit.com - Your Universe Online Approximately 252 million years ago, during the world´s largest mass extinction event, nine out of ten species vanished from the planet. Based on fossil records from sites in South Africa and southwest Russia, many scientists have long thought the predecessors of dinosaurs largely missed the race to fill habitat niches that were emptied during this event. However, according to an international team of scientists, it turns out...

ESA Discovers Origin Of Jupiter's Mysterious Atmospheric Water
2013-04-23 13:41:09

Lee Rannals for redOrbit.com — Your Universe Online The European Space Agency (ESA) says it has unraveled the mystery as to the origin of water observed in the upper atmosphere of Jupiter. ESA's Herschel space observatory found evidence that the water in this part of Jupiter's atmosphere was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994. During this collision, a string of 21 comet fragments pounded into the southern hemisphere of Jupiter, leaving dark...

NASA Says Russian Meteorite 1000 Times Larger Than Originally Estimated

Lawrence LeBlond for redOrbit.com - Your Universe Online Initial reports put last Friday´s (Feb 15) Chebarkul meteorite that exploded over Russia´s Urals region at about 10 tons. But after careful analysis, NASA released new information that puts the meteorite closer to 10,000 tons–1,000 times larger than the estimated size reported by the Russian Academy of Sciences (RAS). “My guess is that someone eyeballed the videos and made an educated guess,” said...

Comet Shoemaker-Levy 9 -- Comet Shoemaker-Levy 9 is so-named because it was the ninth short-period comet discovered by Carolyn and Eugene Shoemaker and David Levy. It was first detected in a photograph taken on the night of March 24, 1993 with the 0.4-meter Schmidt telescope at the Mount Palomar observatory in California, and subsequently observed by many other astronomers. The comet was extremely unusual because it was in fragments, evidently due to a close encounter with the planet...
