Dark Energy Survey Discovers Exotic Supernova
2014-06-26 03:28:35

The first images taken by the Dark Energy Survey (DES) after the survey began in August 2013 have revealed a rare, ‘superluminous’ supernova that erupted in a galaxy 7.8 billion light years away.

Dissecting Dust from Detonation of Dead Star
2014-06-05 08:37:41

Based on observations taken from the Spitzer Space Telescope, NASA scientists have uncovered evidence of a rare Type Ia supernova scenario – when a white dwarf feeds off an aging giant, to the point of explosion.

Supernova Recreation Reveals How Interstellar Magnetic Fields May Have Formed
2014-06-02 10:03:18

Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space.

Supernova Progenitor Revealed

For the first time ever, astronomers have directly confirmed that a rare and extremely massive type of star known as a Wolf-Rayet star died in a violent explosion known as a Type IIb supernova.

Hardy Star Survives Supernova Blast

When a massive star runs out of fuel, it collapses and explodes as a supernova. Although these explosions are extremely powerful, it is possible for a companion star to endure the blast.

Reconstructing The Death Of Supernovae In 3D Offers New Insights
2014-03-18 13:29:42

An astrophysicist has created a new three-dimensional model that provides new insight into the death throes of supernovae. The model is the first to represent the start of a supernova collapse in 3D.

Turbulent Mixing Inside Stars Causes them to Expand, Contract, Eject and Explode, According to 3-D Model Described in the Journal "AIP Advances" WASHINGTON, March 18, 2014 /PRNewswire-USNewswire/

A Wide Range Of Masses Observed In Type Ia Supernovae
2014-03-04 13:06:14

Scientists have been confident in knowing why Type Ia supernovae are all so much alike. Most of them assumed that carbon-oxygen white dwarf stars capture additional mass by stripping it from a companion star or by merging with another white dwarf.

supernova SN 2014J
2014-02-27 04:07:54

NASA’s Spitzer Space Telescope has used its dust-piercing infrared vision to help in analyzing a recently-discovered supernova in galaxy M82.

Sun's Coronal Mass Ejections Behave Like Crab Nebula's Gas Tendrils
2014-02-21 13:28:29

University College of London researchers have explained for the first time the details of how the Sun’s coronal mass ejections behave when falling back onto the star’s surface.

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 -- 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...
