Researchers suggest that Mars' roughly 3.5-mile high Mount Sharp most likely emerged as strong winds carried dust and sand into Gale Crater where the mound sits. If correct, the research could dilute expectations that the mound is the remnant of a massive lake, which would have important implications for understanding Mars' past habitability.

Scientists have used Chandra to make a detailed study of an enormous cloud of hot gas enveloping two large, colliding galaxies. This unusually large reservoir of gas contains as much mass as 10 billion Suns, spans about 300,000 light years, and radiates at a temperature of more than 7 million degrees.
