Question

Match each item to its description.

Answer 1

answer:

A nebula is an enormous cloud of DUST and GAS occupying the space between stars and acting as a nursery for new stars

Neutron stars are thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion, provided that the star is insufficiently massive to produce a black hole.



a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its MASS

Answer 2

Supernova - an explosion of a star

Neutron star - the dense remains of a star

Nebula - a large mass of gas and dust.

In the cosmic lifecycle of stars, nebulae, supernovae, and neutron stars represent distinct stages. A nebula is a vast region of gas and dust in space, serving as the birthplace of stars. Supernovae are dramatic events involving the explosive death of a massive star, releasing an extraordinary amount of energy and ejecting outer layers into space.

The remnants of a supernova may form a neutron star, an incredibly dense celestial object composed mostly of neutrons. Each of these cosmic entities plays a crucial role in the dynamic processes shaping the universe, from stellar birth in nebulae to the cataclysmic demise and remnants observed in the aftermath of supernovae and neutron stars.
