NASA | Scientists Create First Full 3D Model of Eta Carinae Nebula

The video explores Eta Carina, a massive binary star system nearing the end of its life. It discusses the 1840s great eruption, which expelled significant mass and formed a surrounding nebula. Through international collaboration, a detailed spectroscopic mapping of the Homonculus nebula was conducted, leading to the creation of a 3D model. This model revealed unique features and suggested that binarity played a crucial role in the eruption and nebula formation, challenging previous assumptions.

What is the estimated mass of the primary star in the ETA Carinae system?

• 90 solar masses

• 60 solar masses

• 30 solar masses

• 120 solar masses

What significant event did ETA Carinae experience in the 1840s?

• A supernova explosion

• The great eruption

• Formation of a black hole

• A collision with another star

What was unique about the mapping of the Homunculus Nebula?

• It used only 5 slits for mapping

• It was the first to use a 3D printer

• It involved over 100 slits for detailed mapping

• It was done entirely by the Hubble Telescope

What did the new 3D model reveal about the explosion event in ETA Carinae?

• It had no relation to the binary system

• It was symmetrical in nature

• It started on one side and propagated

• It was caused by a single star

How did the new model change the understanding of binarity's role in the great eruption?

• It showed binarity caused the eruption

• It suggested binarity played a role

• It indicated binarity was irrelevant

• It confirmed binarity had no effect
