Through the analysis of isotopes trapped inside ancient quartz crystals, geochemists have realized that the Earth-shattering cosmic impact that laid waste to our young Earth and formed the moon happened 60 million years earlier than thought.
Trying to understand the ancient climate of our own planet is hard enough, but to understand Mars' climatic history, planetary scientists have had to turn to a rather inventive method of climate forensics. Continue reading →
Earth’s finishing touch came with a wallop when a Mars-sized hunk of real estate crashed into the fetal planet some 95 million years after the birth of the solar system -- later than some astronomers thought -- sending up debris that eventually formed moon.
The International Astronomical Union -- the official body that governs the naming and designations of all celestial objects -- has once again spoken out against crowdfunded space naming efforts. Continue reading →
Out of the thousands of craters scarring the face of Mars, one has emerged as the likely source of most of the Martian meteorites that have been recovered on Earth.
Our solar system may be well over 4.6 billion years old but it's still a very active place, and in case you'd somehow forgotten that fact here's a video of our very own lovely moon getting hit by a meteorite traveling at 38,000 mph. Continue reading →
In May 2012, NASA's Mars Reconnaissance Orbiter's low-resolution Context Camera spotted something different in the Martian landscape -- a fresh impact crater. Continue reading →
A recently discovered 1,300-foot-wide (400 meters) asteroid that passed near Earth last month could pay Earth a close visit in 2032.
