Supernova flings star out of the Milky Way - it's the fastest moving star ever

Astronomers have discovered a star racing at a incredible pace of 2.6 million miles an hour (4.2 million kilometers an hour), making it the fastest moving star discovered thus far. It's so fast that it should exit our galaxy and turn into an intergalactic rogue. It doesn't stop here. Such celestial oddities are believed to be spurred in motion by the extreme gravitational tugs found in the vecinity of supermassive black holes, such as the one found at the core of the Milky Way. The new found road runner, however, was most likely flung outward by a Type Ia supernova, one of the most powerful and brightest bursts of energy in the universe. Little is know about such stellar explosions, and the hypervelocity star might submit some valuable clues.

Nova seen Expanding right from the Beginning for the First Time

Here’s something you don’t see everyday – for the first time, astronomers witnessed how a nova is formed right from the onset, capturing and detailing its expansion. The white dwarf turned nova is located some 14,800 light-years away and its study is set to reveal many things about how novas form. The star is dead, long […]

Supernova study might change how speed of light in vacuum is measured

Einstein’s theories suggest that light can not travel faster than c, a constant equal to the speed of light in a vacuum, which is 299,792,458 metres per second (by definition) or about 186,282.4 miles per second. All of our standing physical models are based on this assumption, and so far this idea has yet to […]

Light from huge explosion 12 billion years ago reaches Earth

Intense light from a huge explosion (a gamma ray burst) that took place shortly after the birth of the Universe (12 billion years ago) has reached Earth, and was observed by researchers. Gamma Ray bursts are the strongest explosions since the Big Bang – in just 10 seconds, they release more energy than our sun in […]

Farthest supernova discovered by Hubble helps unravel Universe secrets

Astronomers using NASA’s Hubble Space Telescope have come across the farthest supernova of its type found thus far – a type Ia supernova which exploded some 10 billion years ago. The discovery isn’t just about setting milestones, however. Supernovae act as beacons that help astronomers measure the expansion of the Universe, and this latest finding will help […]

New type of supernova discovered. Hint: it's tiny and faint

Supernovae are highly energetic events caused by the explosion of stars that are at times so bright they can outshine whole galaxies. These are thought to occur in two varieties, but a recently published paper has a described a third type of supernova, one that’s fainter than the other two and distinguishes itself by the […]

A recent study of X-ray and ultraviolet observations from […]

Eta Carinae - the star that exploded, but didn't die

Around 1843, on the night sky all of a sudden a new luminous star made its appearance. That luminous star, which at the time was actually the 2nd brightest star, after Sirius, was actually the result of a explosion in Eta Carinae system – the brightest star in the Milky Way. The eruption spewed a […]

Supernova observed right after its explosion

An unprecedented observation of a supernova right after its explosion has offered scientists extremely valuable insight on these cosmic explosions of biblical proportions.

Betelgeuse to turn supernova and become second Sun? No, not really

There’s been a whole lot of fuss lately, and you guys have also been writing a lot of emails about Betelgeuse turning supernova. I wrote about Betelgeuse and the odds of it going supernova, as well as the damage it would do a while ago, but there’s no harm in doing it again. We are […]

Physicists create a supernova in a jar

A supernova is a stellar explosion of cosmic proportions, that often can outshine the entire galaxy it is located in, before fading away in a matter of weeks or months. During this short period however, supernovae emit as much energy as the Sun emits during its entire life span – it’s the same kind of […]

'Fossil' fireballs found from supernovae

The US-Japan Sukazu observatory reported the finding of some never-before seen embers from the high temperature fireballs that immediately follower the supernovae explosions. Even after thousands of years in which they haven’t been exposed to any heat source, gas within these stellar wrecks is 10.000 hotter than the Sun’s surface. “This is the first evidence […]
