Mystery of the rare supernova explosion finally resolved – RT World News



Astronomers, who have been trying to explain mysterious tufts of light in space for more than a decade, have finally defined the phenomenon as a new kind of exploding star using NASA's Kepler Space Telescope.

In 2012, astronomers who reviewed Kepler's data first noticed a rapid 10 percent bulge in the light of a galaxy 1.3 billion light-years from Earth. Initially, the researchers could not determine if the fleeting flash of light was a massive exploding star (supernova) or simply a computer glitch

Known as flash strobe transients (FELTs), the flash of light would rise and fall less than a month, so it would is difficult for most space telescopes to capture, as they usually gather data from a neighborhood every few days.

The Kepler Spacecraft, whose mission is hunting For exoplanets who photographed a single stretch of the galaxy every 30 minutes for a long time, they were allowed a FELT in action and in action to capture amazing details. " Kepler has opened a new perspective on the sky ," said Jessie Dotson, Kepler's project scientist.

" It was designed to do one thing really well, finding planets around other stars " said Dotson. " To achieve this, it had to deliver high-precision, continuous data that was valuable to other areas of astronomy ."

The data showed researchers that the flash-in-the-pan light is actually the result of a "burp" of a large star in the sky was near his death. It appears that about a year before his demise, the star ejects a dust and gas bubble trapped in the kinetic energy of the star's imminent explosion.

The cocoon was then transformed into a short but incredibly bright light that roughly flashed one-tenth the length of the typical supernova and creating a whole new form of exploding star – a " supernova ."

The discovery is an unexpected feather in Kepler's broad range of abilities and Researchers hope to find more of these items in the ongoing K2 mission or in Kepler's exciting replacement, TESS. You have already discovered more than 20 Supernova examples with data from the Kepler probe.

" This is a new way for massive stars to die and to disperse matter into space," said Armin Rest of the Space Telescope Science Institute in Baltimore, Maryland

A study on that Phenomenon of seven scientists in the US, Australia and Chile has been published in the journal Nature Astronomy.
