I pick out North America’s celestial highlights for the week ahead (which also apply to mid-northern latitudes in the northern hemisphere).

Groundbreaking research into Mars' energy balance reveals a polar surplus driving dynamic weather patterns, including massive dust storms, offering clues to its climate stability. Scientists at the Un

We have long been inspired by the idea that life could reside on Mars – human or otherwise. But fiction is getting closer to reality, says NASA’s former chief scientist, Jim Green. “NASA’s plan, in the long run,

NASA recently released an overhead view of what appears to be massive kidney beans found on Mars' northern hemisphere. In reality, the legume imposters are frozen sand dunes, which are common on Mars and come in a variety of shapes and sizes.

Mars will seem to disappear behind the full wolf moon Monday for many sky-gazers. Throughout January, also look up to see Venus, Saturn and Jupiter in the night sky.

Explore the universe with news on fascinating discoveries, scientific advancements and more. Two new potential strategies for returning crucial samples from Mars to Earth by the 2030s are now on the table, according to NASA. The proposals present ...

NASA’s Curiosity rover is skygazing and photographing lovely examples of noctilucent clouds on Mars. The wispy formations hang like a veil across the sky.

On this date, Jan. 18, 2004, the European Space Agency’s Mars Express finalized mapping of the Red Planet’s south pole. The probe’s OMEGA instrument, which combined data from a camera and an infrared spectrometer, revealed the presence of water ice and carbon dioxide ice for the first time on Mars.
