Text, October 13, 2023. Burst of Light Between Galaxies. Illustration. 
A Luminous Fast Blue Optical Transient (L.F.B.O.T.) is a rare, bright flash in the sky with unknown origins. 
A flash of white light radiates out into shades of blue and red. 
Text, Hubble Space Telescope observations of the latest L.F.B.O.T. discovery have only deepened the mystery. 
Red lines mark the location of a white dot of light above several galaxies. 
Text, Hubble observations placed the L.F.B.O.T. nicknamed "the Finch" in between galaxies. 
Without a clear host galaxy, it is unlikely the Finch is the result of a star exploding as a supernova. 
Other possible explanations include that L.F.B.O.Ts occur when two neutron stars collide, or when stars are torn apart by the gravity of a black hole.
