   NASA’s international space team has discovered an unusual source of light about 90 million light years away, reported sciencedaily.com.

According to earthsky.org, NASA has named this source SDSS1133. Scientist aren’t sure yet whether this anonymous light source is a gigantic black hole that was ejected from its home galaxy or if it’s the remains of a star that exploded during a supernova.

“With the data we have in hand, we can’t yet distinguish between these two scenarios,” said lead researcher Michael Koss, an astronomer at ETH Zurich, the Swiss Federal Institute of Technology. “One exciting discovery made with NASA’s Swift is that the brightness of SDSS1133 has changed little in optical or ultraviolet light for a decade, which is not something typically seen in a young supernova remnant.”

SDSS1133 is part of the Dwarf Galaxy Markarian 177. It is about 2,600 light years from the center of Markarian 177. “With the data we have in hand, we can’t yet distinguish between these two scenarios. One exciting discovery made with NASA’s Swift satellite is that the brightness of SDSS1133 has changed little in optical or UV for a decade, which is not something typically seen in a young supernova remnant,” said Dr Koss, who is the first author of the paper published in the Monthly Notices of the Royal Astronomical Society, reported sci-news.com.

“We suspect we’re seeing the aftermath of a merger of two small galaxies and their central black holes,” said co-author Dr Laura Blecha of the University of Maryland. If two black holes merged, they would release massive amounts of energy in the form of gravitational radiation, reported sci-news.com. The waves would ripple outwards in all directions from the masses. If the black holes have similar masses, they would send out waves in the same sequence in all directions.

The masses would most likely not be similar causing them to launch into opposite directions, which could be powerful enough to knock them out of their home galaxies, reported sci-news.com
