Mars “Shakes Up” Asteroid Surfaces

Mars Stirs Up Asteroid Surfaces

A new study from MIT researchers has found that Mars, like Earth, can “refresh” asteroid surfaces if in close enough contact. 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 […]

Scientists Find Evidence for Granite on Mars

Evidence of Granite on Mars Discovered

Data from NASA’s Mars Reconnaissance Orbiter has led to the discovery of feldspar minerals on Mars, providing the most compelling evidence to date that Mars has granitic rocks. Researchers now have stronger evidence of granite on Mars and a new theory for how the granite – an igneous rock common on Earth — could have […]

New Cassini Image of Saturn and Its Rings

New Cassini Image of Saturn and Its Rings

Using a spectral filter sensitive to wavelengths of near-infrared light centered at 728 nanometers, this newly released image of Saturn and its rings was taken by the Cassini spacecraft this past August. To the Cassini spacecraft’s infrared eyes, Saturn’s graceful clouds sometimes take on the appearance of an impressionist’s painting of the giant planet. This […]

Scientists Show That Atoms Can Work Collectively to Share Light

Scientists Show that Atoms Can Work Collectively

In a newly published study, scientists showed “photon-mediated interaction” between artificial atoms confined to a one-dimensional quantum system. An international team of scientists has shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not […]
