Red supergiant star Betelgeuse may be getting ready to explode into a giant supernova

Betelgeuse, one of the brightest stars in the night sky, has been dramatically dimming recently, indicating that it's about to enter its last phase of life before finally exploding into a supernova. Some scientists believe that Betelgeuse may be ready to go...

Astronomers discover a star that just keeps shining

An international team of astronomers led by Las Cumbres Observatory (LCO) has made a bizarre discovery; a star that just keeps shining. Supernovae, the explosions of stars, have been observed in the thousands and in all cases they marked the death of a star. But in...

'Assassin' targets supernovae in our neighborhood of the universe

While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using small telescopes to study a growing portion of the nearby univer

Insight into one of the closest supernovas discovered in decades

On January 21, 2014, astronomers around the world witnessed a supernova soon after it exploded in the Messier 82, or M82, galaxy. It is one of the closest supernovas discovered in decades. Telescopes across the globe and in space turned their at

The Illustris Simulation - most ambitious computer simulation of our universe yet

No matter what your thoughts and opinions might be on the nature of our universe and Big Bang cosmology here is an interesting video, or better yet, a simulation of what astronomers call the first realistic virtual universe.The super-computer simulation, called &qu

Astronomers find solar storms behave like supernovae

Researchers at the UCL studying details of Coronal Mass Ejections (CMEs) have noticed that those eruptions have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of

Supernova remnant W49B

NASA's Chandra X-ray observatory may have found galaxy's youngest black hole

Observations of a rare supernova remnant by Chandra X-ray observatory indicates the presence of our galaxy’s youngest black hole 26,000 light-years away from Earth. Scientists studied highly distorted remnant of what they believe was a rare supernova explosion

Fermi proves supernova remnants produce cosmic rays

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence that the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward meeting one of
