Scientists have discovered a new astronomical process – it is faster, heavier, and brighter on radio waves than gamma-ray flashes. This is stated in a study by scientists from the Northwestern University of the United States, published in the journal Astrophysical Journal Letters.
The new phenomenon is called the “Fast Blue Optical Transition Process” (FBOT) – it represents a powerful and bright emission of energy. Astronomers recorded one of these events in 2016 – the ejection came from a tiny galaxy located at a distance of about 500 million light-years from Earth.
The event, called CSS161010, made one of the most striking phenomena in the history of space exploration, which scientists were able to fix, to convince themselves of the existence of astronomers. During the flash, gas and dust moved at a speed 55% faster than the speed of light.
FBOT, according to researchers, is a cosmic explosion that is so energetic and hot that it glows blue. Such events reach their maximum brightness within a few days, and then quickly disappear – much faster than ordinary supernova explosions.
We probably had FBOT right in front of our eyes for a long time. But astronomers took them for distortions in the images of galaxies.

In the near future, researchers plan to combine the power of several telescopes to study the phenomenon in more detail.
