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.
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.
