NASA’s Hubble Space Telescope has detected a supermassive black hole in a distant galaxy which has been called “the most massive ever detected far from its central home”.
Since black holes normally anchor the centres of galaxies, researchers were surprised to detect a supermassive black hole speeding uncontrollably. In this instance, researchers think the most likely explanation was due to gravitational waves unleashed by the merger of two black holes as a result of a collision between two galaxies, which has ‘kicked’ the black hole from its usual ‘central’ position. Since not every black-hole merger produces gravitational waves that kick a black hole in the opposite direction, it is an incredibly rare occurrence. Hence, scientists have been testing and determining the different scenarios under which this could happen.
Researchers calculated that this black hole had traveled more than 35,000 light-years from the centre – to illustrate in terms of our own solar system and galaxy, this would be more than the distance between the sun and the centre of the Milky Way.
….the black hole is moving so fast it would travel from Earth to the moon in three minutes. That’s fast enough for the black hole to escape the galaxy in 20 million years and roam through the universe forever.
The immensity of the universe, its spell-dazzling and mesmerising transcendence, knows no bounds.
