| As these stars used up their fuel, they would eventually contract and cool as white dwarfs or explode as supernovae. |
|
| Both supernovae and the rare but brilliant gamma-ray bursts are cosmic explosions marking the deaths of massive stars. |
|
| From the high lancets, sunlight streamed in, and the dust motes flared like supernovae as they passed into the light. |
|
| The title of Paul Gauguin's well-known painting makes a handy list of questions that researchers hope to answer by studying supernovae. |
|
| The acceleration of the Universe can be seen in the redshifts of distant supernovae. |
|
| This was done by using Hubble to peer halfway across the universe to find ancient exploding stars called supernovae. |
|
| We would like to understand better the connection between gamma ray bursts and supernovae. |
|
| With all their brightness, supernovae gradually die away as a result of internal explosions of unsurpassable intensity. |
|
| Violent events such as stellar flares, supernovae and the explosion of galactic nuclei produce a concoction of subatomic particles, primarily protons and electrons. |
|
| For example, amateurs have always been to the fore in discovering comets and novae, hunting for supernovae, and monitoring events happening on the planets. |
|
| Supernovae appear in spiral galaxies like M81 on average once every 100 years or so. |
|
| The explosions of low-mass stars can be triggered by the accretion of mass from a companion star in a binary system to create classical, or Type Ia, supernovae. |
|
| The research teams raced to map the universe by locating the most distant supernovae. |
|
| It is possible that supernovae occur in conjunction with either a satellite planet or binary star. |
|
| The discovery that led to the theory of dark energy depended on studying the red shifts of bright light from supernovae. |
|
| Type II supernovae involve massive stars, usually red supergiants, that have exhausted their energy supply. |
|
| Unlike a regular nova, which releases heavy elements but leaves a dwarf star behind, supernovae explode completely. |
|
| Type II supernovae are massive star explosions but are not as bright as Type Ia supernovae. |
|
| A wide variety of objects are observable at radio wavelengths, including supernovae, interstellar gas, pulsars, and active galactic nuclei. |
|
| Most supernovae are in distant galaxies that are faint even to the most powerful telescopes. |
|
|
|
| Supernovae are among the most spectacular phenomena known to astronomy. |
|
| The new study finds that the supernovae are likely powered by the creation of a magnetar, an extraordinarily magnetized neutron star spinning hundreds of times per second. |
|
| Also highlighted are hydrogen-deficient stars in close binary systems, and massive Wolf-Rayet stars and their relation to Type I supernovae and Gamma-ray bursts. |
|
| Fast radiation-driven winds and supernovae input their huge kinetic power into the interstellar medium in the form of highly supersonic and superalfvenic outflows. |
|
| An understanding of supernovae, the cataclysmic death of a massive star, relies on an understanding of macroscopic matter under extreme conditions. |
