Hubble Space Telescope Discoveries Quiz

What has the Hubble Space Telescope discovered about the jet from the supermassive black hole in galaxy M87?

• It slows down the rotation of the galaxy.

• It destroys nearby stars.

• It triggers star eruptions along its path.

• It captures stars within the jet.

In a double-star system, what happens when a white dwarf accumulates enough hydrogen?

• It forms a new star.

• It erupts into space as a nova.

• It collapses into a black hole.

• It becomes a supernova.

What is the role of the white dwarf in the nova-outburst cycle?

• It resumes siphoning fuel from its companion.

• It stops accumulating hydrogen.

• It is destroyed after each eruption.

• It merges with its companion star.

How might the jet from the black hole influence the frequency of novae?

• By pushing hydrogen fuel onto white dwarfs.

• By capturing white dwarfs within the jet.

• By cooling down the companion stars.

• By stopping the nova-outburst cycle.

What is one possible effect of the jet on the companion star of a white dwarf?

• It turns the star into a black hole.

• It makes the star disappear.

• It heats the star, leading it to overflow.

• It causes the star to shrink.
