Martian Meteorites Yield Clues to the Planet’s Early Atmosphere

April 17, 2014

1 Comment

Using data from meteorites that fell to Earth from Mars, scientists investigate the chemical composition of the Martian atmosphere throughout history, and learn whether the planet has ever been hospitable to life. Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of […]

New research from Arizona State University shows evidence that the Gusev Crater on Mars once held a lake. If desert mirages occur on Mars, “Lake Gusev” belongs among them. This come-and-go body of ancient water has come and gone more than once, at least in the eyes of Mars scientists. Now, however, it’s finally shifting […]

Using data from NASA’s Voyager 1 and 2 spacecraft and Galileo orbiter, scientists have produced the first global geologic map of Jupiter’s moon Ganymede. More than 400 years after its discovery by astronomer Galileo Galilei, the largest moon in the solar system – Jupiter’s moon Ganymede – has finally claimed a spot on the map. […]

NASA Scientists Determine Europa Likely Spun on a Tilted Axis

September 19, 2013

0 Comments

By using data from NASA’s Galileo spacecraft to analyze the distinctive cracks lining the surface of Europa, NASA scientists determined that Europa likely rotated around a tilted axis at some point. This tilt could influence calculations of how much of Europa’s history is recorded in its frozen shell, how much heat is generated by tides […]

A team of researchers has found evidence of water locked in mineral grains on the surface of the moon from an unknown source deep beneath the surface. Scientists have detected magmatic water — water that originates from deep within the Moon’s interior — on the surface of the Moon. These findings, published in the August […]

Martian Meteorite Almost 4 Billion Years Younger Than Previously Thought

July 26, 2013

0 Comments

A team of researchers has revealed that a common group of meteorites from Mars is almost 4 billion years younger than previously thought, providing scientists with a clearer picture of the Red Planet’s evolution. A team led by Western University’s Desmond Moser has solved a Martian meteorite age puzzle that paints a much clearer picture […]

“Hidden Flux” of Material May Help Explain Earth’s Origins

July 17, 2013

0 Comments

Scientists at MIT have discovered a “hidden flux” of material deep in the Earth’s mantle that would make the planet’s overall composition more similar to that of meteorites, supporting the theory that Earth arose from the collision of asteroids. It’s widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a […]

Cosmic Impact Sparked Devastating Climate Change, Caused Mass Extinctions

May 21, 2013

2 Comments

A newly published study reveals evidence of a major cosmic event near the end of the Ice Age, detailing how a cosmic impact sparked climate change that caused mass extinctions. Herds of wooly mammoths once shook the earth beneath their feet, sending humans scurrying across the landscape of prehistoric Ohio. But then something much larger […]
