Martian geology continues to baffle scientists

The official geological history of the planet Mars is a confused and murky tale filled with contradictions and shifting narratives. Astonishing scientific data obtained in the last decade has only deepened the storyteller’s confusion. At the recent 8th Internation

Colliding atmospheres - Mars vs Comet Siding Spring

It's a known fact that planets have atmospheres, but the same can't be said for comets. The atmosphere of a comet, called its "coma," is made of gas and dust that spew out of the sun-warmed nucleus and it's typically wider than Jupiter.La

Observations suggest frequent massive eruptions on Jupiter’s moon Io

Observations made using Keck and Gemini observatories, Hawaii, revealed three massive volcanic eruptions on Jupiter's moon Io within a two-week period in August 2013, leading astronomers to speculate that these presumed rare "outbursts" migh
