Stunning simulation of stars being born is most realistic ever A team including Northwestern University astrophysicists has developed the most realistic, highest-resolution 3D simulation of star formation to date. The result is a visually stunning, mathematically-driven marvel that allows viewers to float around a colorful gas cloud in 3D space while watching twinkling stars emerge. Called STARFORGE (Star Formation in Gaseous Environments), the computational framework is the first to simulate an entire gas cloud — 100 times more massive than previously possible and full of vibrant colors ...

A curiously yellow pre-supernova star has caused astrophysicists to re-evaluate what is possible at the deaths of our Universe’s most massive stars. The team describe the peculiar star and its resulting supernova in a new study published today in Monthly Notices of the Royal Astronomical Society. At the end of their lives, cool, yellow stars are typically shrouded in hydrogen, which conceals the star’s hot, blue interior. But this yellow star, ...

'Oddball supernova' reveals star's death throes before exploding CNN 3 hrs ago By Ashley Strickland, CNN © Aya Tsuboi/Kavli IPMU This artist's illustration shows a potential stellar companion stripping hydrogen from the star that exploded into supernova 2019yvr. Stars experience very violent lives that usually end in dazzling explosions, and scientists have tried for years to determine what happens to massive stars just before this bombastic finale. Now, an unusual supernova is helping researchers piece more of that stellar puzzle together. An international team of resea...

Researchers used NASA’s Hubble Space Telescope to examine the massive star two-and-a-half years before it exploded into a supernova, discovering that it lacked hydrogen.
