Titan's Atmosphere

The “Air” Up There

When NASA Goddard scientists Martin Cordiner and Conor Nixon took a look at the chemical make-up of the atmosphere of Titan using a millimeter wave telescope, what they found was surprising. Cordiner led an international team in a study of Saturn’s moon using the Atacama Large Millimeter/submillimeter Array (ALMA), a … Continue Reading →

Anatomy of an Exosolar System

A good chunk of the exoplanets that we’ve detected so far are huge, Jupiter-sized and larger. A lot of them are orbiting their stars at very short distances – it might seem strange to think that planets bigger than Jupiter are orbiting their stars closer than Mercury orbits the Sun, … Continue Reading →

NASA’s Mars Reconnaissance Orbiter has revealed new images that show some Martian slopes that change over the course of the Martian seasons. The scientists involved in the project think that best explanation for these seasonal changes would be the flow of salty water, much like our oceans. I wonder what … Continue Reading →
