\n Astronomers have spotted a mystery object that they say could be a black hole or a neutron star.<\/p>\n

Both black holes and neutron stars are the remains of dead stars.<\/p>\n

\u201cWhen the most massive stars die, they collapse under their own gravity and leave behind black holes; when stars that are a bit less massive die, they explode in a supernova and leave behind dense, dead remnants of stars called neutron stars,\u201d explains the Laser-Interferometer Gravitational-Wave Observatory (LIGO) in a statement.<\/p>\n

LIGO, which is operated by MIT and Caltech, supported by the National Science<\/a> Foundation, explained that astronomers have long been fascinated by the \u201cgap\u201d that lies between black holes and neutron stars. \u201cThe heaviest known neutron star is no more than 2.5 times the mass of our sun, or 2.5 solar masses and the lightest known black hole is about 5 solar masses,\u201d it explained in a statement. \u201cThe question remained: does anything lie in this so-called mass gap?\u201d<\/p>\n

In a new study undertaken by LIGO and the Virgo detector in Europe, scientists announced the discovery of an object of 2.6 solar masses, putting it firmly in the mass gap. \u201cThe object was found on August 14, 2019, as it merged with a black hole of 23 solar masses, generating a splash of gravitational waves detected back on Earth by LIGO and Virgo,\u201d scientists said in the statement.<\/p>\n

A paper on the discovery has been accepted for publication in The Astrophysical Journal Letters.<\/p>\n

Astronomers from Northwestern University, the University of Wisconsin, Milwaukee and Italy\u2019s University of Padova also participated in the research.<\/p>\n

\u201cWe\u2019ve been waiting decades to solve this mystery,\u201d said study co-author Vicky Kalogera, a professor at Northwestern University, in the statement. \u201cWe don\u2019t know if this object is the heaviest known neutron star or the lightest known black hole, but either way it breaks a record.\u201d<\/p>\n

\u201cThis is going to change how scientists talk about neutron stars and black holes,\u201d added co-author Patrick Brady, a professor at the University of Wisconsin, Milwaukee and the LIGO Scientific Collaboration spokesperson, in the statement. \u201cThe mass gap may, in fact, not exist at all but may have been due to limitations in observational capabilities. Time and more observations will tell.\u201d<\/p>\n

The cosmic merger was dubbed GW190814 and resulted in a final black hole about 25 times the mass of the sun, located about 800 million light-years from Earth. Scientists note that some of the merged mass was converted to a blast of energy in the form of gravitational waves.<\/p>\n

\u201cBefore the two objects merged, their masses differed by a factor of 9, making this the most extreme mass ratio known for a gravitational-wave event,\u201d said scientists, in the statement.<\/p>\n

A light-year, which measures distance in space, equals about 6 trillion miles.<\/p>\n

Last year, in a separate study, scientists, for the first time, detected a black hole devouring a neutron star.<\/p>\n

The Australian National University (ANU), which participated in the research, explained that the \u201ccataclysmic event\u201d was detected on Aug. 14, 2019, by gravitational-wave discovery machines in the US and Italy. The machines detected ripples in space and time from an event that happ<\/a>ened about 8,550 million trillion kilometers away from Earth, ANU said in a statement.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
