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

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.

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.

Less than two months after it first began repeatedly scanning the sky, the ESA’s Gaia space observatory has discovered its first supernova – a powerful stellar explosion that had occurred in a distant galaxy located some 500 million light-years from Earth.

Astronomers using ESA’s Integral gamma-ray observatory have demonstrated beyond doubt that dead stars known as white dwarfs can reignite and explode as supernovae.

New research by a team of UK and European-based astronomers is helping to solve the mystery of what caused a spectacular supernova in a galaxy 11 million light years away, seen earlier this year.

Using NASA’s Hubble Space Telescope, a team of astronomers has spotted a star system that could have left behind a “zombie star” after an unusually weak supernova explosion.

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...

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...
