The discovery, based largely on observations from NASA's Spitzer Space Telescope, should provide a better understanding of the roots of our universe, and how the very first black holes, galaxies, and stars all came to be. 'We have found what are likely first-generation quasars, bom in a ...
A black hole is an area in space which has a very strong field of gravity and as a result, light is unable to escape from it. Due to this,black holesare invisible. In order to observe them, telescopes are equipped with special instruments which observe the behaviour of material and stars...
An international team of astronomers has uncovered an entirely new method to investigate the behavior of active black holes. They observed a sample of active black holes, located in the centers of 136 galaxies, and found a consistent pattern in their emission of microwave and X-ray light, regar...
One of them is that the horizon of (stationary) black holes can “trap” photons i.e., a photon may remain on the horizon forever. As a stationary horizon is always a null hypersurface, and since photons travel in null directions, a photon could move along the null direction defined by...
until the discovery of neutron stars in 1960. After that, astronomers started to take note of the effects of these possible black holes in space. Theergosphereis an area of distorted space around the black hole that is stretched and twisted, resulting in some strange phenomena that scientists ...
stream of gas and stars and when the collision between the two galaxies happened gas was led to the some giant black hole. The supermassive black holes was feed twice and burped twice. A previous theory says that black holes go to a cycle of burping and this new discovery sustain the ...
The Discovery of Stellar-Mass Black Holes Because X-rays are such important tracers of black holes that are having some of their stellar companions for lunch, the search for black holes had to await the launch of sophisticated X-ray telescopes into space. These instruments must have the resolut...
This Molecule May Be the Source of Life on Earth Neutron Stars Could Be Nurseries for Axions Scientists Found First Triple Black Hole System Will the Universe End in a “Long Freeze”? We May Have Found Our First-Ever Exomoon Could Future Astronauts Dine on Asteroids?
Stellar black holes — small but deadly When a star burns through the last of its fuel, the object may collapse, or fall into itself. For smaller stars (those up to about three timesthe sun's mass), the new core will become aneutron staror awhite dwarf. But when a larger star colla...
“It was important to me that we didn’t bias our black hole search toward dwarf galaxies,” Polimera said. “But in looking at the whole census, I found that the new type of growing black holes almost always showed up in dwarfs. I was taken aback by the numbers when I first saw ...
