Distant supergiant star investigated in detail

Astronomers from the University of La Laguna, Spain and elsewhere have performed spectroscopic observations of an early B-type supergiant star known as 2MASS J20395358+4222505. Results of this observational campaign, published ...

Astronomers witness a dying star reach its explosive end

For the very first time, astronomers have imaged in real time the dramatic end to a red supergiant's life, watching the massive star's rapid self-destruction and final death throes before it collapsed into a Type II supernova.

Chemical signatures of iron predict red supergiant temperature

Red supergiants are a class of star that end their lives in supernova explosions. Their lifecycles are not fully understood, partly due to difficulties in measuring their temperatures. For the first time, astronomers have ...
