Kepler solves the cause of the mysterious supernova explosion



Astronomers who have been trying for ages to explain the cause of the mysterious outbursts of light in space have finally described the phenomenon as a new kind of exploding stars. The mystery, which spanned over a decade, was finally solved with the help of NASA's Kepler Space Telescope.

In 2012, astronomers got a glimpse of this phenomenon when reviewing Kepler's data. A 10% light burst from a galaxy, 1.3 billion light-years from Earth, was recorded by Kepler. Scientists could not tell if the flash of light came from an exploding star or a computer glitch. Scientifically known as FELTs (Fast Evolving Luminous Transients), this phenomenon would occur and die within a month, which would make space telescopes more difficult to capture because they record data from one area every few days. The FELT, which was recorded in 2015, evolved over 2.2 days and faded within 10 days, making the discovery of this phenomenon virtually undetectable.

The Kepler spacecraft aims to explore exoplanets by taking long-term recordings of a single galaxy route. Kepler detects faint changes in the brightness of a star through the transient stages of the planets around it. This requires the recording of high-precision and continuous data. During his mission, Kepler was able to capture the activity of a FELT in remarkable detail. Peter Garnavich, professor and departmental director of astrophysics and cosmology physics at the University of Notre Dame and co-author of the study, described the event as "the most beautiful light curve we'll ever receive for a quick transient." 19659005] Scientists discussed the probable cause of these particularly rapid events and concluded with a simple theory. The stars "burp" before exploding and do not generate enough radioactive energy to appear later. As the supernova invades the gas expelled in the burp, astrophysicists discover a bolt of lightning. The supernova then disappears beyond the detection of space telescopes. "Our conclusion was that this was a massive star that exploded, but had a mass loss – a wind – a few years before it exploded" Garnavich described. "After the blast, there was a shock in the wind and it caused this big flash, but it turns out to be a rather weak supernova so we can not see the rest of the light within a few weeks.

The NASA-funded Kepler telescope and K2 mission are expected to be fueled in just a few months. Twenty additional supernova examples have been extracted by Kepler for comprehensive studies. Astrophysicists applauded Kepler's contribution to the analysis of cosmic phenomena and further exploration of FELTs.
