Team led by Indian scientists finds X-ray signature of boundary around black holes

September 22, 2020 8:14 pm

While definitive proof of the existence of such objects is a holy grail of modern physics and astronomy, they said only one supermassive black hole with the mass more than six billion times the mass of the Sun has so far been imaged using the surrounding radiation in radio wavelengths.

Gravitational waves detected from black hole collision event 800 million years ago

The gravitational signal from this merger event travelled for 800 million years through the universe and arrived at the network of two advanced-LIGO detectors – at Hanford, Washington and Livingston, Louisiana, USA and the advanced-Virgo detector in Cascina, Italy, in the wee hours of August 15 2019, just past 2.40 am IST.

Gravitational waves from unequal mass black holes detected

Named GW190412, the merger was collectively detected on April 19, last year. The highly-sensitive signals were detected using Laser Interferometer Gravitational wave Observatory (LIGO) and Virgo, located in the US and Italy, respectively.

Explained: How a tiny wiggle in the young universe gave birth to black holes

According to the scientists, as time passes, this uniform energy prevailing in the Inflation Field wanes out. As a result, the universe resumes its normal decelerating rate.

Astronomers discover 83 supermassive black holes

March 15, 2019 12:59 pm

Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

Four new gravitational waves detected from black hole mergers

The position of the binary black holes, located by the LIGO and VIRGO observatories, were spotted 2.5 billion light-years from Earth, and identified with a precision of 39 square degrees.

Background space hum may reveal hidden black holes: Study

Scientists believe that deep space holds many more black holes compared to earlier estimates, which can now be 'heard'.

Lack of evidence put Stephen Hawking's Nobel Prize hopes in black hole

March 15, 2018 8:08 pm

Scientists mourning the death of Stephen Hawking believe that the late British cosmologist did not win a Nobel Prize, as his theories have never been proven.

Strange star helps discover massive inactive black hole

January 18, 2018 7:02 pm

Scientists at the European Southern Observatory have detcted an invisible black hole, which was found with a star revolving around it.

Supermassive black holes present in every galaxy, determine lifespan of stars: Study

January 02, 2018 8:16 pm

New research has shown that every galaxy has a supermassive black hole, that decides how stars will be formed, and when they will 'switch off'.
