| Stars like our sun form white dwarfs, but those about 1.5 times heavier become supernovas and collapse to form a neutron star. |
| I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes. |
| The new supernovas were found in galaxies ranging from four to seven billion light years away. |
| As these stars used up their fuel, they would eventually contract and cool as white dwarfs or explode as supernovae. |
| The acceleration of the Universe can be seen in the redshifts of distant supernovae. |
| From the high lancets, sunlight streamed in, and the dust motes flared like supernovae as they passed into the light. |
