Betelgeuse is known for being a type of "variable star," meaning its brightness fluctuates, at times dramatically, as it inches toward an eventual grandiose collapse and stellar explosion, known as a supernova. In recent years, the star has grown noticeably brighter....
Rare quadruple supernova on our 'cosmic doorstep' will shine brighter than the moon when it blows up in 23 billion years Atacama Telescope reveals earliest-ever 'baby pictures' of the universe: 'We can see right back through cosmic history' Scientists discover smallest g...
Using the ALMA, astronomers have observed star birth and potential death sites in a galaxy 13.2 billion light-years away. Their observations revealed an ionization process by newly formed stars and a massive cavity that might represent a “superbubble” from supernova explosions, marking th...
Since I did this 4 days ago I am seeing about a 33% increase in my battery life. Typically I was getting about a day and a half, now I'm getting over 2 days on my Galaxy Watch6 Classic. Me too 18 Likes Reply 11 Replies Previous 1 2 Next Ellin Supernova Options...
Recent three-dimensional computer simulations suggest thatneutrinos— very low mass subatomic particles — made in the creation of the neutron star drive bubbles that speed away from the center of the explosion. These bubbles continue driving the shock wave forward to trigger the supernova ...
A star that shined with 2.5 million times the light of our Sun has disappeared from the night sky. It is possible that the star collapsed into a black hole without first triggering a supernova – a rare event, even in the context of dying stars.
The SN type can be determined from the host galaxy type: an evolved, red elliptical lack-ing enough recent star formation to provide a significant population of core-collapse supernovae. The classification is further supported by diagnostics available from the observed colors and tem-poral behavior...

April 3, 1994: Observing M51 with my ATM 8" f/6 newt in the backyard and noticed a star near the nucleus that wasn't on the chart in Roger Clark'sVisual Astronomy of the Deep Sky. Discovered Supernova 1994I, one day too late - it was first discovered by Georgia amateurs the previo...
ultra-deep spectroscopic survey in the near infrared (NIR), that will target a mass-limited sample of galaxies during two of the most fundamental epochs of cosmic evolution: the formation of the first galaxies (at z \gtrsim 6; cosmic dawn), and at the peak of galaxy formation activity (...
