Latest Planetary geology Stories
In order to achieve its goals of conducting prolonged operations on Mars and sending astronauts on missions that would take them into deep space, NASA is investing in new technologies designed to help them find and use breathable air, drinkable water and other natural resources originating from places other than Earth.
The surface of Mars is pocked and scarred with giant impact craters and rocky ridges, as shown in this new image from ESA’s Mars Express that borders the giant Hellas basin in the planet’s southern hemisphere.
NASA’s Mars Reconnaissance Orbiter (MRO) continually makes high-resolution observations of the surface of Mars. Recent images have revealed that the gullies on the surface are mainly formed by seasonal freezing of carbon dioxide and not liquid water.
3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound.
Breaking research news from a team of scientists led by Carnegie's Ho-kwang "Dave" Mao reveals that the composition of the Earth's lower mantle may be significantly different than previously thought.
A new study from ETH Zurich geoscientists Giovanni Leone, however, suggests that lava, rather than water or tectonic plate activity, cut the gigantic valleys into the red planet's landscape.
Well preserved gullies and debris flow deposits in a crater on the southern hemisphere of Mars are providing new evidence through their geomorphological attributes that they were formed by the action of liquid water in relatively recent geological times.
Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles.
John Lennon was born on October 9, 1940 in Liverpool, England. He started his first band, The Quarrymen, while still in high school. After Paul McCartney and George Harrison joined the band the name was changed to The Beatles.
Scientists writing in the journal Nature Geoscience say that a similar process to that which allows water to yank oils from ground coffee in order to make a cup of joe in the morning, could be how the Earth's core formed.
Harrison Schmitt was a NASA astronaut, and is also an American geologist. He was born Harrison Hagan "Jack" Schmitt on July 3, 1935 in Santa Rita, New Mexico. After high school, he went to the California Institute of Technology and received a B.S. degree in science in 1957. He then went to Norway to study geology at the University of Oslo. In 1964, Schmitt earned a Ph.D. in geology from Harvard University. After receiving his doctorate, he worked at the U.S. Geological Survey's...
The Planet Venus is the second planet from the sun. It is often called the evening star or morning star and is brighter than any object in the sky except the sun and the moon. Because its orbit lies between the sun and the orbit of the earth, Venus passes through phases like those of the moon, varying from a large bright crescent when the planet is near inferior conjunction (nearest the earth) to a smaller silvery disk when it is at superior conjunction (farthest from the earth). Since...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
