NASA's Swift satellite puts faraway stars and galaxies under a new lens. A combination of X-ray and ultraviolet observations from NASA's Swift satellite allow researchers to gain a more detailed look at specific stars and their activities. Most recently Swift was used to study a Type Ia supernova. While it's been known that Type Ia supernovae originate with a remnant star called a white dwarf, the X-ray and ultraviolet views allow researchers to view the events and matter that cause the...

Type Ia supernovae are violent stellar explosions whose brightness is used to determine distances in the universe. Observing these objects to billions of light years away has led to the discovery that the universe is expanding at an accelerating rate, the foundation for the notion of dark energy. Although all Type Ia supernovae appear to be very similar, astronomers do not know for certain how the explosions take place and whether they all share the same origin. Now, a team of researchers has...

Astronomers announced on Wednesday a new class of supernova after observing six ultra-bright flashes of ancient exploding stars in deep space. The explosions, which were ten times brighter than any other previously seen supernova, may illuminate star-forming clouds in far-off, primitive galaxies, allowing scientists to observe stellar creation. The scientists directly observed four of these exploding stars, while another two previously unexplained supernovae are now believed to belong to this...

In the past decade, robotic telescopes have turned astronomers' attention to scads of strange exploding stars, one-offs that may or may not point to new and unusual physics. But supernova (SN) 2005E, discovered five years ago by the University of California, Berkeley's Katzman Automatic Imaging Telescope (KAIT), is one of eight known "calcium-rich supernovae" that seem to stand out as horses of a different color. "With the sheer numbers of supernovae we're detecting, we're discovering weird...

Scientists have developed a new explanation for how youthful type Ia supernovae are formed. Dr. Bo Wang and colleagues from the Yunnan Observatory of the Chinese Academy of Sciences created a new model that links the formation of type Ia supernovae to the transfer of a material from a helium star to a white dwarf companion. White dwarves are dense remnants of stars like the Sun. Scientists theorize that these white dwarves borrow matter from a nearby star. Once the mass of the remnant star...

In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time. The galaxy, known as MCG +05-43-16, is 380 million light-years from Earth. Until this year, astronomers had never sighted a supernova popping off in this stellar congregation. A supernova is an extremely energetic and life-ending explosion of a star....

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...
