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 […]

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 […]

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 […]

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 […]

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 […]
