Latest Planetary geology Stories
The catastrophic melting and outflow of a buried ice lake formed the lumpy, bumpy floor of an ancient impact crater on Mars known as Aram Chaos.
A newly released image from the ESA offered a groundbreaking peek under the surface of Mars courtesy of the Mars Express orbiter.
The over 600 double-layer ejecta craters on Mars resulted because the planet's surface was covered by a thick sheet of ice during the time of impact, geologists from Brown University have discovered.
Newly released images from the European Space Agency (ESA) show how water and other natural forces shaped craters and other surface features on Mars.
One of the more popular theories surrounding the formation of the planets involves the countless collisions of smaller objects in orbit around the sun 4.5 billion years ago. However, proponents of that theory are missing one thing: the Earth's chemical composition is distinctly different from the meteors that are currently striking the planet.
Recently, the MESSENGER Science Team proposed names for 10 rupes on Mercury. The International Astronomical Union (IAU), which has been the arbiter of planetary and satellite nomenclature since 1919, approved the names.
Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA’s Mars Express on 4 January.
For the first time ever, new maps of the subsurface of Mars show buried channels below the surface of the planet. These channels suggest evidence of flooding on a planet that has been considered by scientists to be cold and dry for the last 2.5 billion years.
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...
