Phys.org / Astronomy's dirty window to space: A detailed map of dust in the Milky Way

When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it appears? Or does the star merely look reddish, since its light has had to travel through a cloud of ...

Phys.org / Weighing in on a Mars water debate: Analysis challenges previous findings

More than 3 billion years ago, Mars intermittently had liquid water on its surface. After the planet lost much of its atmosphere, however, surface water could no longer persist. The fate of Mars's water—whether it was buried ...
