Five Of The Biggest, Baddest Supernova Varieties

The video explores various types of supernovas, including core collapse, electron capture, pair instability, and Type 1A supernovas. It discusses notable supernovas like 1987 A, the Crab Nebula, 2007 BI, 2016 APS, and SN 1006, explaining their unique characteristics and the scientific insights they provide. The video highlights the role of supernovas in cosmic creation and the ongoing research to understand these explosive events.

What is a core collapse supernova?

• A supernova that occurs when a star's core collapses under gravity.

• A supernova that happens when two stars collide.

• A supernova caused by the explosion of a white dwarf.

• A supernova that results from the fusion of hydrogen atoms.

What is the role of iron in a core collapse supernova?

• Iron acts as a tipping point, leading to the star's collapse.

• Iron absorbs energy, causing the star to expand.

• Iron is ejected into space, forming new stars.

• Iron provides energy for the star to continue fusion.

What was unique about the supernova that created the Crab Nebula?

• It was the first supernova observed with a telescope.

• It resulted in the formation of a black hole.

• It was the brightest supernova ever recorded.

• It was an electron capture supernova.

How did astronomers solve the mystery of the supernova in 1054?

• By observing a similar event in 2018.

• By using advanced telescopes.

• By finding a companion star.

• By discovering a new type of supernova.

What distinguishes a pair instability supernova like 2007 BI?

• It results in the formation of a neutron star.

• It involves the fusion of hydrogen and helium.

• It is caused by the collision of two white dwarfs.

• It lacks hydrogen and helium in its light spectrum.

What was unusual about the light from Supernova 2007 BI?

• It was only visible for a few days.

• It contained no hydrogen or helium.

• It showed signs of a black hole.

• It was brighter than any other supernova.

What is a pulsational pair instability supernova?

• A supernova that forms a black hole.

• A supernova that results from a single massive explosion.

• A supernova that occurs in multiple stages over time.

• A supernova that only involves hydrogen fusion.

What is the significance of the supernova of 1006?

• It was the first supernova observed with a telescope.

• It was the brightest supernova in recorded history.

• It resulted in the formation of the Crab Nebula.

• It was the first Type 1A supernova discovered.

What happens when a white dwarf exceeds 1.4 times the mass of the Sun?

• It becomes a neutron star.

• It starts fusing hydrogen again.

• It undergoes a Type 1A supernova explosion.

• It forms a black hole.

What is a Type 1A supernova?

• A supernova resulting from the explosion of a white dwarf.

• A supernova that forms a neutron star.

• A supernova that involves the fusion of iron.

• A supernova caused by the collision of two stars.
