Astronomers Say Supernova Will Be Visible From Earth Within 50 Years
2013-10-31 16:04:47

A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way galaxy within the next 50 years.

Violent Youth Seeded The Universe With Iron
2013-10-31 05:07:20

The universe underwent a turbulent and violent youth more than 10 billion years ago, as evidenced by iron spread evenly between galaxies in one of the largest galaxy clusters in the Universe.

Largest Known Star Self Destructs

A group of international scientists have observed as the largest known star in the Universe tore itself apart.

Magnetic Jets Stars Final Transformation
2013-09-17 12:37:48

New observations of magnetic jets may shed some light on how stars transition into planetary nebulae.

Cosmic Rays Origins

Streaming across the Universe are high-energy charged particles, known as cosmic rays. For more than their origins have remained a mystery.

How Fast Does A Supernova Shockwave Travel? A Japan Team May Have The Answer
2013-08-13 14:51:55

Some of the most spectacular explosions this side of the Big Bang, supernovae generate unthinkable amounts of force and energy and new research from Keio University in Japan has measured the expansion velocity of a supernova shockwave for the first time.

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

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...
