Massive Meteor Explodes Over Russia: Buildings Damaged, Hundreds Injured
2013-02-15 08:57:01

Lawrence LeBlond for redOrbit.com - Your Universe Online A meteor streaked across Russia´s early morning skies on Friday before violently exploding, sending a rain of debris onto the Earth below. The flash and boom shattered windows and meteor particles left damage in its wake, injuring more than 900 people in the Ural Mountains region. Marina Mokvicheva, regional health minister in Chelyabinsk, the Russian city that had felt the brunt of the impact, told the Washington Post that...

Meteorite Linked To Martian Crust
2013-01-03 13:08:12

Lee Rannals for redOrbit.com - Your Universe Online Researchers have identified a new class of Martian meteorite that they believe originated from Mars' crust. The team wrote in Thursday's issue of Science Express that this new meteorite contains more water than any other Martian meteorite ever found. The sample is the only one found that dates back to 2.1 billion years ago, which is an early era on Mars known as the Amazonian. The meteorite, known as Northwest Africa (NWA) 7034,...

Sutter's Mill Meteorite Under The Microscope
2012-12-21 05:32:02

Lee Rannals for redOrbit.com - Your Universe Online A meteorite study has led scientists to believe that asteroid surfaces may be more complex than previously thought. Scientists from around the world have come together to work on a meteor analysis of the Sutter's Mill meteorite that fell down to Earth in April 2012. The scientists reported in the journal Science that this particular meteor is an unusual example from a rare group known as carbonaceous chondrites. Samples from this...

Evidence Found That Exploding Star Gave Birth To Solar System
2012-12-17 15:00:11

Lee Rannals for redOrbit.com — Your Universe Online University of Chicago researchers wrote in the journal Earth and Planetary Science Letters that they found the radioactive isotope iron 60 low in abundance, and well mixed in solar system material, leading to the notion that the force of an exploding star prompted the formation of the Solar System. Scientists look for remnants of stellar explosions in meteorites to help determine the conditions under which the solar system...

Mars Inside And Out May Have Had Differing Geological Histories
2012-11-20 05:50:00

April Flowers for redOrbit.com - Your Universe Online A team of scientists led by the Carnegie Institution for Science recently studied the hydrogen in water from the interior of Mars and found that Mars was formed from similar building blocks to that of Earth. There are differences, however, in the later evolution of the two planets, which implies that terrestrial planets such as Earth have similar water sources — chondritic meteorites. Unlike Earth, however, rocks on Mars that...

Violent Collision Created Rare Meteorite
2012-11-16 11:32:50

April Flowers for redOrbit.com - Your Universe Online Some meteorites found on Earth contain strikingly beautiful, translucent, olive-green crystals embedded in an iron-nickel matrix. These "space gems," called pallasites, are only found in a tiny fraction of the total number of meteorites, but they have fascinated scientists since they were first identified as originating in outer space more than 200 years ago. A new study, published in the journal Science and led by John Tarduno at...

NASA Chat To Discuss Why Meteorites Matter
2012-11-07 15:43:24

NASA Meteorites are pieces of asteroids and other bodies like the moon and Mars that travel through space and fall to the earth. They are rocks that are similar in many ways to Earth rocks, but it is exciting to find a piece of another planet here on Earth. Meteorites fall to Earth all the time and are distributed over the entire planet, so you could even find one in your own backyard! Scientists believe the meteorites may hold answers to unsolved mysteries about our solar system and...

Mars Rocks Similar To Mexican Ones
2012-10-29 18:42:40

Lee Rannals for redOrbit.com — Your Universe Online A team of researchers is claiming gypsum rocks found at Cuatro Ciénegas in Mexico are similar to those NASA's Curiosity rover is sitting at on Mars. The team analyzed the bacterial communities that have survived after fire and water forged the rocks millions of years ago. "Cuatro Ciénegas is extraordinarily similar to Mars. As well as the Gale crater where Curiosity is currently located on its...

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...
