Dying Stars May Cause  that Confound Scientists

Sudden, Bright Blasts

Extremely fast cosmic

 explosions puzzling scientists may be outbursts arising from dying stars, new research suggests.

 Fast Blue Optical Transients(FBOTs)

because of their "blue" heat and very rapid evolution, only a handful of these outbursts have been recorded.

A new model suggests the bursts 

happen amid the chaotic environment of a dying star which shoot out powerful jets smashing into layers of gas sloughing off the star as its fusion slows down. 

FBOTs are most visible in optical

wavelengths and change within a matter of days. They get bright rapidly, then fade away, much faster than a supernova star explosion typically does. 

Astronomers have said 

FBOTs may be related to gamma-ray bursts, another set of powerful explosions associated with dying stars.

FBOTs are also

 visible in radio and X-ray waves, which also appear to have an explanation in the model.
