Supernova

Above and Beyond: Eta Carinae

Roughly 8,000 light-years from Earth, an unstable star, Eta Carinae, teters on the brink of destruction. In fact, it might be two massive stars in tight orbit around each other, with one or both expected to explode before too long.

(DESCRIPTION) 
 Text, Eta Carinae 


Roughly 8,000 light-years from Earth, a star known as Eta Carinae is on the brink of destruction. 


Eta Carinae is unstable and prone to violent outbursts. 


The temperamental star sits hidden at the center of two billowing lobes of dust and gas, which it blew out during an eruption witnessed in the 19th century. 


Among the most massive stars known, Eta Carinae might actually be two massive stars orbiting tightly around one another. 


Astronomers expect one or both stars to blow up as a titanic supernova before too long. 


In fact, an explosion might have already happened, but we won't receive news of the blast until its light reaches us 8,000 years later.
