While type Ia supernovae are commonly used to locate dark energy in the universe, their origins have remained somewhat mysterious.

By analyzing the remnant of a recently-exploded star, researchers have confirmed what computer models have long predicted – when stellar giants die, they do so in a lopsided fashion, as the core of the star is flung off in one direction and debris is sent flying the opposite way.

NASA sounding rocket was launched towards a supernova remnant, with the goal of examining the X-rays emitted by the object to determine the composition of this 20,000-year-old explosion’s debris.

Astronomers found that the type of supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before, and this questions how fast the universe has been expanding.

NASA studied the 'crime scene' left behind from an explosion of an Ia supernova and discovered that a single white dwarf star is to blame.

Dark energy is so difficult to understand, but this specific type of supernovae could help determine the rate at which the universe is expanding.

For the first time ever, NASA has managed to capture a detailed time-lapse of a "mini supernova," and they believe this catch will have a big impact on studying stellar explosions.

One explosion is cool. But four? That's great. Astronomers observed a star explode as a supernova 4 different times in this effect known as the Einstein Cross.

Because the debris fields of exploded stars, known as supernova remnants, are very hot, energetic, and glow brightly in X-ray light, NASA’s Chandra X-ray Observatory has proven to be a valuable tool in studying them. The supernova remnant called G299.2-2.9 (or G299 for short) is located within our Milky Way galaxy, but Chandra’s new image of it is reminiscent of a beautiful flower here on Earth.

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...
