Everything, including black holes, will eventually evaporate: Study
Updated : 2 years, 9 months ago IST
Researchers found Black holes will eventually evaporate due to Hawking radiation, but the event horizon is not as important as previously thought. New theoretical research from Radboud University's Michael Wondrak, Walter van Suijlekom, and Heino Falcke has shown that Stephen Hawking was pa

Researchers reveal smoke particles from wildfires can erode ozone layer
Updated : 3 years ago IST
Smoke from a wildfire may travel to great heights and linger there for up to a year. The protective ozone layer that shields the Earth from the sun's harmful UV rays while suspended there may be eroded by these particles, revealed a recent MIT study.

Updated : 3 years ago IST
A recent publication in the European Heart Journal, a publication of the European Society of Cardiology, provides the first evidence that ozone levels above the World Health Organization (WHO) limit are significantly associated with an increase in hospital admissions for heart attacks, heart

Smoke particles from wildfires can erode ozone layer: Research
Updated : 3 years ago IST
A wildfire can send smoke into the stratosphere, where it can linger for up to a year. According to a new MIT study, these particles can cause chemical reactions that erode the protective ozone layer that protects the Earth from the sun's harmful ultraviolet radiation while suspended there.

Mysterious object being dragged into supermassive black hole at Milky Way'
Updated : 3 years ago IST
Scientists are interested in an item that is close to the supermassive black hole at the centre of the Milky Way galaxy because it has undergone a rapid and dramatic evolution. According to a recent study, the object known as X7 might be a cloud of gas and dust that resulted from the collisi

New discovery sheds light on very early supermassive black holes
Updated : 3 years ago IST
One of the most extreme galaxies known to exist in the very early Universe has a fast-expanding black hole, according to astronomers from the Universities of Texas and Arizona. New information about the creation of the first supermassive black holes is revealed by the discovery of the galaxy

New model of ringing black holes created by physicists
Updated : 3 years ago IST
When two black holes collide into each other to form a new bigger black hole, they violently roil spacetime around them, sending ripples called gravitational waves outward in all directions.

Massive fuel-hungry black holes feed off intergalactic gas: Research
Updated : 3 years, 1 month ago IST
Research led by the University of Southampton has revealed how supermassive black holes (SMBHs) are feeding off gas clouds which reach them by travelling hundreds of thousands of light years from one galaxy to another.

Hubble finds hungry black hole twisting captured star into donut shape
Updated : 3 years, 1 month ago IST
Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation.

NASA's retired Compton mission reveals superheavy neutron stars
Updated : 3 years, 2 months ago IST
Astronomers studying archival observations of powerful explosions called short gamma-ray bursts (GRBs) have detected light patterns indicating the brief existence of a superheavy neutron star shortly before it collapsed into a black hole. This fleeting, massive object likely formed from the

Scientists hunt for the second-closest supermassive black hole
Updated : 3 years, 3 months ago IST
Two astrophysicists at the Center for Astrophysics Harvard & Smithsonian have suggested a way to observe what could be the second-closest supermassive black hole to Earth: a behemoth 3 million times the mass of the Sun, hosted by the dwarf galaxy Leo I.

Scientists achieve milestone of directly observing dusty ring around black
Updated : 3 years, 3 months ago IST
An international team of scientists has achieved the milestone of directly observing the long-sought, innermost dusty ring around a supermassive black hole, at a right angle to its emerging jet. Such a structure was thought to exist in the nucleus of galaxies but had been difficult to observ
