Stars

an enormous cloud of dust and gas occupying the space between stars and acting as a nursery for new stars.

NGSS.HS-ESS1-3

very large star of high luminosity and low surface temperature, thought to be in a late stage of evolution when no hydrogen remains in the core to fuel nuclear fusion.

NGSS.HS-ESS1-1

a small very dense star that is typically the size of a planet, formed when a low-mass star has exhausted all its central nuclear fuel and lost its outer layers as a planetary nebula.

NGSS.HS-ESS1-3

extremely large red giant star with a minimum of 15 solar masses. The best known red supergiant is Betelgeuse, with a luminosity about 10,000 times that of the Sun.

NGSS.HS-ESS1-3

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

NGSS.HS-ESS1-3

a celestial object of very small radius and very high density, composed predominantly of closely packed neutrons, thought to form by the gravitational collapse of the remnant of a massive star after a supernova explosion

• neutron star

• black hole

• gravity

• nuclear fusion

a region of space having a gravitational field so intense that no matter or radiation can escape.
