[ Watch The Video: The Evolution Of Mars ] Lee Rannals for redOrbit.com - Your Universe Online NASA released a new video showing how its Mars Atmosphere and Volatile Evolution (MAVEN) mission will be able to look back at the history of the Red Planet. Mars is a cold and barren dessert with red soil and little atmosphere. However, scientists believe that billions of years ago this planet could have not only had a thick atmosphere, but was warm enough to support oceans of liquid water....

Newly Discovered Asteroid Has Slight Chance Of Impacting Earth

[ Watch the Video: Earth Receives A Quick Visit From Asteroid ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers working at the Crimean Astrophysical Observatory in Ukraine found a new asteroid on October 13, 2013 and NASA confirmed it came within about 4.2 million miles of Earth on September 16. While 4.2 million miles seems far enough away, experts said the rock, known as asteroid 2013 TV135, will have a slight chance of impacting Earth when it returns in 2032. While...

Just In Time For ISON: Scientists Discover Ancient Earth Comet Impact

[ Watch the Video: Ancient Earth Comet Impact Evidence ] Lee Rannals for redOrbit.com - Your Universe Online Comet ISON is getting closer to making its close pass by the sun, but what would happen if it had a brush with our planet instead? New evidence shows it would be devastating. International scientists have discovered the first ever evidence of a comet entering Earth's atmosphere and exploding. This celestial object rained down fire across the Earth, obliterating every life form...

New Evidence Indicates Moon Is 100 Million Years Younger Than Thought

[ Watch the Video: Moon May Be Much Younger Than Previously Believed ] Lawrence LeBlond for redOrbit.com - Your Universe Online Earth’s closest neighbor, the moon, has been studied intently by astronomers for centuries. In that time, we thought we had discovered nearly everything there is to know about the origins of our natural satellite. However, new research by geochemist Richard Carlson of the Carnegie Institution of Washington has shaken things up a bit. According to Carlson's...

Large Mammals Of Younger Dryas Wiped Out By Asteroid
2013-09-03 06:40:55

[ Watch the Video: Younger Dryas Impact Wiped Out Large Mammals ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists long fascinated with trying to understand a dramatic global climate shift have revealed new evidence that could explain a few things. A new study, funded by the National Science Foundation and to be published online in the Proceedings of the National Academy of Sciences (PNAS) Early Edition, has found that a cataclysmic asteroid or comet impact in the...

Chelyabinsk Meteorite Had Close Encounter In Space Prior To Earth Impact
2013-08-27 06:59:32

Lawrence LeBlond for redOrbit.com - Your Universe Online The Chelyabinsk meteor that exploded over Russia’s Ural Mountains region earlier this year was found to have either collided with another celestial body or had a close encounter with the sun prior to reaching Earth. Researchers from the Institute of Geology and Mineralogy (IGM) in Novosibirsk, Russia announced today fragments of the Chelyabinsk meteorite – the main body that fell to the bottom of Chebarkul Lake near...

Meteor Impact Crater Found Beneath Iowa Town
2013-07-11 04:39:36

Lee Rannals for redOrbit.com - Your Universe Online A meteor crater from 470-million-years-ago lies buried several hundred feet beneath the town of Decorah, Iowa, according to an airborne geophysical survey reported in EARTH Magazine. Geologists first hypothesized the crater's existence while examining cuttings from water wells drilled near the town. During this examination they discovered evidence of a previously unknown shale deposit that was nearly a perfect circle, roughly 3.4 miles...

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...

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...
