Mystery astronomical object may be a ‘black neutron star’

The video explores the life cycle of stars, focusing on their transformation into neutron stars or black holes. It highlights a recent discovery by LIGO and Virgo of a mysterious object in the mass gap between neutron stars and black holes. This object, possibly the lightest black hole or the heaviest neutron star, was part of a binary system with a larger black hole. Their collision emitted gravitational waves detected in 2019, leading to new insights into stellar evolution.

What happens to a star that is 1 to 2.5 times the size of our Sun?

• It becomes a white dwarf.

• It becomes a neutron star.

• It becomes a red giant.

• It becomes a black hole.

What is the fate of a star that is five times the size of our Sun or larger?

• It becomes a neutron star.

• It becomes a white dwarf.

• It collapses into a black hole.

• It becomes a supernova.

What is the significance of the 2.6 solar mass object discovered by LIGO and Virgo?

• It is the first binary star system discovered.

• It challenges the understanding of the mass gap.

• It is the smallest known black hole.

• It is the largest known neutron star.

What is the term some scientists use to describe the 2.6 solar mass object?

• Black neutron star

• Dark matter star

• Mini black hole
