Russian Meteor Produced A Shockwave That Traveled The Globe Twice
2013-06-28 07:07:05

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteor that blazed a trail across the morning sky in Russia this past February left a shocking impact on not just the Ural Mountains region, but the entire world. A new report published in the journal Geophysical Research Letters states the shockwave from the meteoric explosion on the morning of February 15, 2013 traveled around the globe -- not once, but twice. Scientists, led by Alexis Le Pichon of the French...

Comets Brought Organic Ingredients For Life
2013-06-06 08:23:25

April Flowers for redOrbit.com - Your Universe Online When it came to jump-starting life, the early Earth was not a very hospitable place. New research from the Lawrence Livermore National Laboratory (LLNL) and the University of Ontario Institute of Technology (UOIT) reveals that life on Earth may indeed have come from outer space. LLNL scientist Nir Goldman and UOIT´s Isaac Tamblyn — a former LLNL postdoctoral researcher — found that billions of years ago icy comets...

Moon Mystery: GRAIL Data Show How Gravitational Anomalies Developed
2013-05-31 06:19:45

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Purdue University and MIT have solved the long-standing mystery of why the moon´s gravitational force is stronger in some areas than in others. This irregular gravitational force has been observed ever since the first satellites were sent to the moon, when orbiting probes would pass over certain craters and impact basins, and periodically swerve off course before plunging toward the lunar surface and then...

Slooh To Broadcast Moon's Asteroid Collision
2013-05-20 14:27:46

Lee Rannals for redOrbit.com - Your Universe Online An organization aimed at bringing celestial event programming to everyone with a computer, iPhone or iPad is planning to broadcast the fiery explosion that took place on the moon just a few months ago. On March 17 NASA astronomers witnessed how the Moon was rocked by a violent impact from an 88-pound asteroid, creating a flash nearly 10 times as bright as anything the space agency had seen before. Now Slooh says it wants to bring the...

Moon's Water Supply Came From Earth, Not From Comet Impacts
2013-05-09 13:34:08

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Prior to the Apollo Moon missions, scientists conjectured that the Moon would be extremely dry, that even below the surface of the Magnificent Desolation little or no water would be present. But the rocks brought back by the lunar explorers revealed that the Moon, while still dry compared to Earth, contained a surprising amount of water. Furthermore, the composition of the Moon led scientists to the current Big Impact...

At a major planetary defense conference in Flagstaff, AZ, last evening, the Planetary Society announced the winners of its 2013 Shoemaker Near Earth Object (NEO) grants and was recognized itself for the Society´s long history of international leadership in the detection and mitigation of threatening asteroids, and other planetary discoveries. “As the Chelyabinsk impact demonstrated, asteroid impacts happen; they are dangerous, destructive, with no regard for human life,”...

Asteroid Caused Massive Firestorm Leading To Global Extinction
2013-03-28 05:17:03

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Colorado claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet´s species. According to Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences (CIRES) and colleagues, the firestorm...

Comet May Have Caused Chicxulub Crater And Dinosaur Extinction
2013-03-24 05:34:56

Brett Smith for redOrbit.com - Your Universe Online One of the most popular theories on the disappearance of the dinosaurs surrounds the 110 mile-wide Chicxulub crater in Mexico. Many scientists believe the extinction was caused by an asteroid that crashed into Earth, leaving only a massive crater behind. However, a group of American scientists is presenting a theory that the culprit was actually a speeding comet, not a relatively slow-moving asteroid as many theories assert....

NASA Warns Lawmakers More Funding Needed To Protect Earth From Doomsday Asteroids
2013-03-20 09:23:02

Lawrence LeBlond for redOrbit.com - Your Universe Online The giant Chicxulub crater in Yucatan is evidence that sometime around 65 million years ago a massive asteroid smashed into the earth wiping out most life that existed at that time, including all non-avian dinosaurs. While it is hard to imagine a similar scenario taking place today, there is currently little that we could do but sit and “pray.” That is unless, of course, the government can do more now to ensure...

Software Helps Analyze Damage Caused By Chelyabinsk Meteor
2013-03-08 18:59:31

Lee Rannals for redOrbit.com - Your Universe Online On Friday, February 15, a massive meteor exploded in the sky over Russia's Ural Mountains region, injuring more than 1,500 people and at least 200 children. Now, a lecturer in Aerospace Engineering at the University of Southampton has released the results of a simulation of the Chelyabinsk meteor using high-tech software called NEOImpactor. Professor of engineering and environment Dr. Hugh Lewis was able to use the simulation tool to...

Crater -- A crater is a circular depression on the surface of a planet, moon, asteroid, or other celestial body. Craters are typically caused by meteorite impacts, although some are caused by volcanic activity. In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake. Ancient craters whose relief has disappeared leaving only a...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
