Using the AstroSat satellite, astronomers from the University of Calgary, Canada, have identified 20 supernova remnants (SNRs) in the Andromeda Galaxy, which exhibit diffuse ultraviolet emission. The finding, presented in ...
Japanese astronomers have performed long-term multiwavelength observations of a supernova remnant (SNR) designated SNR G298.6−0.0. They found that G298.6−0.0 is an old SNR interacting with molecular clouds. The new findings ...
An international research team led by the University of Minnesota Twin Cities has measured the size of a star dating back 2 billion years after the Big Bang, or more than 11 billion years ago. Detailed images show the exploding ...
