Not exact matches

Chemical calculations show that helium hydride should be visible in clouds around distant galaxies and supernovas, or even in modern planetary nebulas (shells of gas expelled by aged, sunlike stars).

A ring of hot spots (in images from the Hubble Space Telescope) gradually lit up as a shock wave from supernova 1987A plowed through a loop of gas that had been expelled by the star tens of thousands of years before the explosion.

A shock wave from that collapse will speed outward, violently expelling the star's outer layers in a massive explosion known as a supernova.

Supernovas pack a lot of punch, to put it lightly — they can outshine galaxies and expel more energy than our Sun's lifetime output, making them the largest explosions in space.

A new study led by Keiichi Ohnaka, a researcher at Catholic University of the North in Chile, sought to understand how the distant red supergiant star Antares manages to expel so much matter off its surface as it nears the end of its life and nears its finale as a spectacular supernova.

Some are found in globular clusters, but most move in a huge cloud around the disk called the galactic halo, which has a luminous inner component defined by globular star clusters and other easily observable stars (with coronae of hot gas possibly expelled by supernovae and of high - velocity neutron stars) and an outer dark - matter component inferred from its gravitational impact on the Milky Way's spiral disk.

The outer layers rebound from the core and are expelled into space in a gaint supernova explosion.
