Type Ia supernova
2014-09-14 04:24:52

Chuck Bednar for redOrbit.com - Your Universe Online 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, the agency announced on Friday. According to the ESA, the supernova was located during a sudden rise in the galaxy’s brightness that occurred between two Gaia observations...

European Space Agency 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. The finding came after the unique signature of gamma rays from the radioactive elements created in one of these explosions was captured for the first time. The explosions in question are known as Type Ia supernovae, long suspected to be the result of a white dwarf star blowing up because of a...

Galaxy M82 supernova

University of Manchester 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. The supernova, a giant explosion of a star and the closest one to the Earth in decades, was discovered earlier this year by chance at the University of London Observatory. These phenomena are extremely important to study because they provide key information about our...

zombie star after supernova

Felicia Chou, NASA Headquarters and Donna Weaver / Ray Villard, Space Telescope Science Institute 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. A supernova typically obliterates the exploding white dwarf, or dying star. On this occasion, scientists believe this faint supernova may have left behind a surviving portion of the dwarf star -- a sort of zombie...

Iron 'Fingerprints' Point Astronomers To Supernova Remnants
2014-07-03 03:27:00

NASA An international team of astronomers using data from the Japan-led Suzaku X-ray observatory has developed a powerful technique for analyzing supernova remnants, the expanding clouds of debris left behind when stars explode. The method provides scientists with a way to quickly identify the type of explosion and offers insights into the environment surrounding the star before its destruction. "Supernovae imprint their remnants with X-ray evidence that reveals the nature of the...

Dissecting Dust from Detonation of Dead Star

Brett Smith for redOrbit.com - Your Universe Online A supernova occurs when a tiny white dwarf star detonates in a massive blast and a common class of these explosions, called Type Ia, occurs when two white dwarfs orbiting each other collide. Based on observations taken from the Spitzer Space Telescope, NASA scientists have uncovered evidence of a much rarer Type Ia supernova scenario – when a white dwarf feeds off an aging giant, to the point of explosion. According to a report...

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

Lee Rannals for redOrbit.com - Your Universe Online Astronomers, publishing a paper in the Monthly Notices of the Royal Astronomical Society, show how Type Ia supernovae have a range of masses. 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. Scientists assumed this class of supernova were...

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

redOrbit Staff & Wire Reports - Your Universe Online NASA’s Spitzer Space Telescope has used its dust-piercing infrared vision to help in analyzing a recently-discovered supernova in galaxy M82. It joined with several other instruments to create a detailed portrait of the stellar explosion, officials from the US space agency announced on Wednesday. The new supernova, SN 2014J, is the closest of its kind to be observed in the past few decades and has launched a global observing...

OAKLAND, Calif., Jan. 30, 2014 /PRNewswire-USNewswire/ -- Chabot Astronomers are tracking the latest supernova about 12 million light years away. Identified as "2014J," a Type 1A supernova, the phenomenon is occurring in Messier-82 (M82), also known as the Cigar Galaxy. Supernovae occur when a star explodes emitting a massive amount of energy in a short span of time; the star literally collapses under its own gravity. 2014J actually exploded about 12 million...

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...

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...
