NASA’s Kepler space telescope helped scientists explore fast-evolving luminous supernova, which is one of the most mysterious exploding phenomena booming in the space, says a scientific review disclosed online in the issue of Nature Astronomy on March 26, 2018.
An extremely ephemeral event has just perplexed scientists since a decade, which they have named by as the fast-evolving luminous transient, as it has so very fleeting duration. Astronomer Ed Shaya spotted something uncommon while he was observing the data obtained by the Kepler space telescope of NASA in 2012.
“We collected an awesome light curve,” stated Armin Rest from the Space Telescope Science Institute in Baltimore, Maryland, “We were able to constrain the mechanism and the properties of the blast. We could exclude alternate theories and arrive at the dense-shell model explanation. This is a new way for massive stars to die and distribute material back into space.”
Ed Shaya noticed a luminary coming from the galaxy, which quickly illuminated by 10 per cent. This sudden and surprising discovery made Shaya just excited instantly, nervous too. According to the astronomers, the effects of this luminous event may introduce with the massive explosion of a supernova, or may be with more troubling situation.
David Khatami from the University of California at Berkeley said in a statement that, “The fact that Kepler completely captured the rapid evolution really constrains the exotic ways in which stars die. The wealth of data allowed us to disentangle the physical properties of the phantom blast, such as how much material the star expelled at the end of its life and the hypersonic speed of the explosion.”
