By tracking the phases of six exoplanets, astronomers have tracked their daily weather cycles for the first time.
No, this isn't humanity's attempt at laser-etching Saturn's cloudy atmosphere with interplanetary graffiti, this is the stunning view at the bottom of a brand new adaptive optics system intended to superboost the clarity of deep space.
Observations by NASA's Spitzer Space Telescope have revealed wild atmospheric changes on a well studied exoplanet -- changes that could be driven by extreme volcanic activity.
Scientists using NASA’s Mars-orbiting MAVEN spacecraft discovered a mysterious cloud of dust hundreds of miles above the planet’s surface -- and no explanation for how it got there.
Amateur astronomers gazing at Mars discovered gigantic plumes soaring more than 125 miles above the planet’s surface, a phenomenon that so far defies explanation.
Mars' atmosphere is often viewed as frigid and unchanging, but in studies of the red planet's aeolian processes, nothing could be further from the truth -- particularly where Martian dust devils are concerned. Continue reading →
This summer ESA's Venus Express spacecraft daringly dipped into the upper atmosphere of our neighboring planet during a risky but successful aerobraking maneuver. Continue reading →
When Comet Siding Spring made its historic close approach with Mars last month, the icy interloper showered the Martian upper atmosphere with meteors -- and several robots were on hand to monitor the shower's effects. Continue reading →
