How do dying stars shed their mass and become red supergiants? New observations of the red supergiant Betelgeuse are surprising and confusing to scientists.

Green Glow from Ancient Galaxies Surprises Scientists

The galaxies are greener on the other side of the universe, it seems: A new analysis reveals that some of the most distant galaxies ever observed are radiating green light, a finding that could deeply impact developing models of those early galaxies.

Mir may have had its problems, but the space station set a precedent for international cooperation and advanced the science of space travel.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) observatory, astronomers surveyed galaxies that existed when the universe was only 1 billion years old. The scientists detected ionized carbon filling the space between the stars, in

Galaxy of Horrors

Considered to be the first cold super Earth, this exoplanet began to form a Jupiter-like core of rock and ice, but couldn’t grow fast enough in size. Its final mass is five times that of Earth. The planet's nickname is Hoth, after a planet from Star Wars.
