To get an idea of how the early solar system may have formed, scientists often look to asteroids. These relics of rock and dust represent what today's planets may have been before they differentiated into bodies of core, ...
(Phys.org) —Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, Ceres.
For nearly as long as astronomers have been able to observe asteroids, a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites—the remnants of asteroids that have crashed to Earth?
