About this Image
The super massive star Eta Carinae is embedded in a huge gas and dust cloud. It is situated approx. 9,000 light-years away.
Eta Carinae suffered a giant outburst in the year 1841, when it became one of the brightest stars in the southern sky.
Though the star released as much visible light as a supernova explosion, it survived the outburst.
