Hello Venus, Hello Mercury!

Quick. How many naked eye planets can you see in the night sky? If you answered three — Jupiter, Mars and Saturn — congratulations, you’re three-fifths correct! But two others have been sneaking up from behind when we weren’t paying attention. Venus has recently returned to the evening sky after a many-month hiatus, and Mercury’s putting…

ALMA Reveals Planets Forming Right Before Our Eyes

TW Hydrae is a special star. Located 175 light years from Earth in the constellation Hydra the Water Snake, it sits at the center of a dense disk of gas and dust that astronomers think resembles our solar system when it was just 10 million years old. The disk is incredibly clear in images made using the Atacama…
