Heavy Metals In The Infant Universe
2013-08-07 05:55:59

A star exploded more than 12 billion years ago, ripping itself apart and blasting debris outward in twin jets at nearly the speed of light. The star shone so brightly at its death that it outshone its entire galaxy by a million times.

Gold Created By Colliding Stars
2013-07-18 04:18:47

A gamma-ray burst (GRB) created by the collision of two neutron stars has given researchers new insight into how gold, one of the rarest elements on Earth and in the entire universe, is formed.

Astronomers Detect Relatively Cool Supernova Remnant
2013-07-05 14:00:28

An international team of astronomers detected surprisingly low temperatures in the remnant of the supernova 1987A, helping to explain the mystery of why space is filled with dust grains and molecules.

Astronomers May Have Witnessed A Collapsing Neutron Star
2013-07-05 04:16:37

Radio observatories have recently noticed bursts of radio light emerging in the night sky. The intense flashes exist for only a moment then disappear and do not seem to repeat.

Dark Energy Survey Will Look For Supernovae
2013-07-01 18:32:12

The greatest cosmological puzzle of the 21st century continues to be to measure, characterize and understand the source of dark energy – the apparent force that is driving the accelerating expansion of the Universe.

Stellar Collision Survivor New Type Pulsating Star
2013-06-28 14:54:18

Astronomers have discovered that the brightness of the remnant of a stellar collision can vary in a way that scientists have not observed before.

Computer Simulations Shed New Light On Neutron Star Formation
2013-06-28 04:30:08

Researchers from the Max Planck Institute for Astrophysics have, for the first time, created three-dimensional computer models in order to study the formation of neutron stars at the center of collapsing stars, officials from the German research center announced earlier this week.

Chandra Discovers Supernova Remnant Emission Is Synchrotron Radiation
2013-06-26 16:32:40

Astronomers will be reporting details about a supernova remnant known as G1.9+0.3 in the upcoming issue of The Astrophysical Journal Letters.

Supernova Gold Standard For Normal
2013-06-19 13:37:32

A group of astronomers has released a dataset based on 32 nights of repeated observations of supernova 2011fe, creating a "gold-standard" atlas for Type 1a supernovae.

White Dwarf

White Dwarf -- A white dwarf is a a star supported by electron degeneracy. A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star goes through a red giant phase and then expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf. A typical white dwarf is half as massive as the Sun, yet only...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Supernova
2004-10-19 04:45:42

Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first element...

Stellar Evolution -- Stellar evolution is the process of formation, life, and death of stars. It is one of the major topics of cosmogony. Star Birth and Life A star starts out as an enormous cloud of gas and dust many light-years across. Star formation begins when the cloud begins to condense under its own gravity. The processes that initiate this contraction are not fully understood. The cloud fragments fuse into stellar mass clouds known as protostars. Protostars do not emit...

Nova -- A nova is an enormous nuclear explosion caused by the accretion of hydrogen onto the surface of a white dwarf star. When a white dwarf has a close companion star, the companion will often begin to have its outer atmosphere drawn away from it by the white dwarf's gravity as the companion star ages and expands into a red giant. The gases so captured consist primarily of hydrogen and helium, the two principle constituents of matter in the universe. The gases are compacted on the...
