gamma ray burst

Gamma-ray bursts (GRBs) are flashes of gamma rays associated with extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe.[1] Bursts can last from ten milliseconds to several minutes. The initial burst is usually followed by a longer-lived "afterglow" emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, microwave and radio).[2]

Earth was hit by a massive gamma-ray burst in the 8th century

The most powerful explosion in the Universe – a gamma-ray burst-  might have hit Earth during the middle ages. Luckily enough for our ancestors the event had its origin thousands of light years away and its effects went by unnoticed. Last year, scientists found  unusual levels of radioactive carbon-14 in cedar trees in Japan and spikes [...]

Most powerful stars are actually vampire binary systems. The weaker feeds on the stronger

A new research has found that the massively powerful O-type stars, which can be up to 90 times more powerful than our own sun, actually come in pairs most of the time, as a binary system. The two stars wrapper in this dance have a special kind of relationship developed with one another. Thus, one [...]

Astronomers paint a clearer picture of how supernovae are born

Supernovae are one of the most energetic and brightest events in the cosmos, often so powerful they outshine whole galaxies. They’re considered  to play a major role in our understanding of the Universe, which is why scientists have invested so much time and effort into studying them. A recent study of X-ray and ultraviolet observations from [...]

One third of the discovered gamma rays so far have unknown sources

Wed, Oct 19, 2011

1 Comment

Set it went into operation, Fermi’s Large Area Telescope has detected 1873 gamma rays out in space, of which only two thirds have had their sources traced. Typically, gamma rays are huge bursts of energy generated by the collision between two stars or by black holes, however more than 600 discovered blasts still don’t have an explanation [...]

Gamma-ray bursts might cause mass extinction on Earth

Most of us tend to believe the Earth is a safe heaven, with little regard to outerwordly consequences. The truth is our planet, although without a doubt a true gem within our galaxy, is susceptible to a slew of events triggered from within or well beyond our solar system. A lot of them are very [...]

Intense Gamma Ray blast indeed traced back to supermassive black hole

Fri, Jun 17, 2011

0 Comments

We previously reported about an incredible gamma ray burst triggered by a black hole, so powerful that nothing like this was observed before, or even dimmed possible. A recently published paper in the journal Science sheds more light on the subject. A typical gamma ray burst commonly occurs when massive stars explode due to collisions [...]

Dormant Supermassive black hole arises stronger than ever

Sat, May 7, 2011

It’s still unclear if it was all about a stellar meal or if it was simply gas, or some other relatively unimportant phenomena that awoken the sleeping giant, but for the first time, astronomers have observed the awakening of a sleeping supermassive black hole. The sleeping giant It appeared to be a day just like [...]

Black hole in Dragon’s belly swallows star and everything goes nutty from here

  The Draco constellation (which is Latin for Dragon) is located at about 3.8 billion light years from Earth; just like every dragon that has at least some common sense, it breathes fire, especially after carelessly eating a nearby star. Rewind. A mysterious cosmic blast in the Draco constellation is causing waves that continue to [...]
