Superstar Eta Carinae

Eta Carinae is the most luminous and massive stellar system within 10,000 light-years of Earth. The system, which comprises two massive stars, is known for its surprising behavior. It erupted twice in the 19th century for reasons scientists still don’t understand. 

Over the past 11 years, astronomers at NASA’s Goddard Space Flight Center have developed a model based on routine observations of the stars using ground-based telescopes and multiple NASA satellites.
