A team of astronomers has witnessed a supernova smashing into a nearby star, shocking it and creating an ultraviolet glow that reveals the size of the companion.
In a type "Ia" supernova, a white dwarf star explodes after it gains matter from a companion star in the same binary star system. One of the leading theories is that the supernova happens when two white dwarf stars merge. But a competing theory says that the companion could be a normal or giant star that survives the explosion, although not without some damage.
Astronomers know they occur when a white dwarf explodes in a binary system with another star, but the properties of that second star and how it triggers the explosion have remained elusive for decades. The supernova, named iPTF14atg, is located 300 million light years away in the galaxy IC831.

- A Humongous Star Explosion
The "SN 2006gy" explosion took place in the galaxy called NGC 1260, 240 million light-years away. It was 100 times more powerful than most typical supernovas, the brightest and most energetic ever recorded. It was first detected in September 2006, using...

The shimmering colors visible in this image, clearly shows the remarkable complexity of the Twin Jet Nebula [also known as PN M2-9]. The image highlights the nebula?s shells and its knots of expanding gas in striking detail. The glowing and...
- Star Got Swallowed By A Warp In Space.
A star has slipped out of view of astronomers due to the space-time warp. The disappearing star is part of a binary star system called J1906. It's a pulsar, which means it's a rotating neutron star, the result of a massive star collapsing in...
- Difference Between Nova And Supernova
As I said before a Nova is a completely different process compared with a Supernova. A Nova is actually a sudden brightness that spreads across the surface of a White dwarf--kind of a star. The brightness is the result of a fusion reaction that happens...
- What Is A Supernova?
There was a star somewhere around the sky staying almost unnoticeable, and got burst out suddenly in to a blistering brightness; it's just a one more Supernova!--if not Nova. The energy and light that was radiated in to the sky during the star's...
