In astronomy, a fast blue optical transient (FBOT) is an explosion event similar to

supernovas A supernova is a powerful and luminous explosion of a star. It has the plural form supernovae or supernovas, and is abbreviated SN or SNe. This transient astronomical event occurs during the last stellar evolution, evolutionary stages of a mass ...

Gamma-ray bursts In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies. They are the most energetic and luminous electromagnetic events since the Big Bang. Bursts can last from ten millise ...

which presents high optical luminosity between those but rises and decays faster and has its spectra concentrated on the blue range. It is caused by some very high-energy astrophysical process not yet understood but thought to be a type of supernova with events occurring at not more than 0.1% of the typical rate.
