Up to the present time, as the scientist, his team failed to catch black holes in the first phases of their "meal" when they have already begun to destroy the star, but haven't started to eat her remains and throw the "leftovers" in the form of jets, narrow beams of plasma accelerated to near-light speeds.
A team of astronomers observed this event in a pair of colliding galaxies that lies almost 150 million light-years from Earth. The black hole of 20 million solar masses is tearing up a star that is two times bigger than our sun.
Another scientist, Clive Tadhunter from the University of Sheffield, told Gizmodo that "the association of a jet with a particular type of accretion event - the tidal disruption of a star - could potentially improve our understanding of jet formation in general", regardless of what formed the jet.
The researchers suggest that the star swirled around the black hole, emitting intense x-rays and visible light, when it was absorbed by the black hole, writes Mashable.
The first indication came on January 30, 2005, when astronomers using the William Herschel Telescope discovered a burst of IR emission coming from the nucleus of one of the Arp 299 galaxies. The astronomers had expected to see visible light and X-rays (below the visible spectrum) created by the TDE, but think they only observed infrared and radio waves because of the amount of dust in the galaxy.
Over the following decade, scientists monitored the object using a variety of different equipment including the Very Long Baseline Array and the European VLBI Network, as well as other different radio telescopes.

Tidal disruption events are rare and occur about once every 10,000 years in a typical galaxy because its central black hole is not actively consuming any material and consequently, not give off any light. Therefore, tidal disruption events, such as the one recently recorded, offer a unique opportunity to study the vicinity of these powerful objects.
As Perez-Torres from the Spanish National Research Council explains, supermassive black holes spend a great deal of time without devouring anything, so they are not particularly active.
Dr Rob Beswick, from the Jodrell Bank Centre for Astrophysics at the University of Manchester's School of Physics and Astronomy, UK, said: "This is a fantastic discovery and an extremely important result in astronomy".
Astronomers used radio and infrared telescopes while looking at a supermassive black hole.
They published their findings in the 14 June online issue of the journal Science.
