GRB 080319B, um objecto situado a 7 bili\u00f5es de anos-luz, esteve vis\u00edvel a olho n\u00fa durante 2 horas. Foi no dia 19 de Mar\u00e7o. \u00c9 o objecto mais distante<\/strong> que alguma vez esteve vis\u00edvel a olho n\u00fa<\/strong>.<\/p>\n

Um GRB, Gamma Ray Burst, resulta da explos\u00e3o de uma estrela. \u00c9 dif\u00edcil dar uma ideia da pot\u00eancia do GRB 080319B. Esta \u00e9 a melhor descri\u00e7\u00e3o que encontrei:<\/p>\n

Let me put this in perspective for you. Imagine a one megaton<\/strong> nuclear weapon detonating. That\u2019s roughly 50 times<\/strong> the explosive yield of the bomb dropped on Nagasaki. Devastating.<\/p>\n

The Sun, every second<\/strong> of every day of every year, gives off 100 billion times<\/strong> this much energy. That\u2019s every second. A star is a terrifying object.<\/p>\n

In the few seconds that a gamma-ray burst lasts, it packs a million million million times<\/strong> that much energy into its beams. In other words, for those few ticks of a clock the GRB is sending out more energy than the Sun will in its entire lifetime.

\nThe burst was detected by Swift at 2:12 ET on March 19 and was one of five gamma-ray bursts detected that day, the same day that famed science fiction writer Arthur C. Clarke<\/a> died.
\n“Coincidentally, the passing of Arthur C. Clarke seems to have set the universe ablaze with gamma-ray bursts,” said Swift science team member Judith Racusin, a Penn State graduate student.<\/p>\n","protected":false},"excerpt":{"rendered":"
