SUNSET: 
Close Companions Help Stars Make More Carbon
Massive stars can produce twice as much carbon when they have a close binary companion, according to a new study. The result is a small but important step in understanding the cosmic origin of elements.
Glowing Serpent Found in the Sky
Astronomers have discovered a star generating a pinwheel of dust 8,000 lightyears away, which may shed some light on the last stages of massive star evolution.
Too Many Massive Stars in Universe's Youngest Galaxies
A new method of measuring star formation in the earliest galaxies finds that they’re producing more massive stars than expected — a result that could affect our understanding of how galaxies grow their stars.
Massive Stars Grow By Eating Finger Food
Astronomers don’t understand how the galaxy’s most massive stars form, but a new simulation sheds light on the process of stellar birth.
Telltale Shock Waves from Runaway Stars
Astronomers are now finding dozens of fast-moving runaway stars by searching for the bow shocks they create in interstellar gas and dust.
The Most Distant Star Ever Seen?
Astronomers have detected what might be the farthest star ever spectroscopically observed. The bright object blazes in an unusual location, too, perhaps giving insight into star formation in unconventional environments.
