ETA CARINAE

This stars system was a combination of Eta Carinae A, B and C, three specific stars.
In the mid of 19th century, Eta Carinae B and C collapsed. B ingested C and a massive explosion generated the Homoncula Nebula.
Today, Eta Carinae A and Eta Carinae B compose this binary system.
Eta Carinae A is a giant star, maybe almost more than 1000 the size of our Sun.
The only way to view the Homoncula Nebula is to go to the Austral hemisphere.
