The huge object formed about 470 million years after the Big Bang, researchers said. The study was published recently in Nature Astronomy. The researchers said the findings confirm their theory: Supermassive black holes existed in the very early universe. The United States space agency, NASA, used...
Astronomers recently discovered the most distant black hole ever observed in the X-ray wavelength, and it has some unusual properties that could help uncover the mysteries of how the largest black holes form. Within the center of most galaxies lies asupermassive black hole, which is hundreds of ...
A small seed is more difficult to explain, however, because such sources would have to continuously accrete matter at twice their Eddington limit (the point at which the gravitational pull of the object is cancelled by the radiation pressure it applies through the accretion to the surrounding ...
A.This kind of object is a black hole. B.Is there a white hole in the universe? C.Now picture yourself near a black hole. D.However, we’ve never seen a white hole. E.And could a black hole become a white hole? F.We’d never see anything escape from the black hole. ...
The object grew to more than 800 million times the mass of the sun when the cosmos was only 5 percent its present age
(and of which Pluto is now regarded as the largest member), suggests to them that something about ten times as massive as Earth has changed those orbits. If you knew where to look, this planet-sized object would be visible through a suitable telescope. And Konstanin Batygin and Michael ...
Interestingly, one of the 12 galaxies in z66OD was a giant object with a huge body of gas, known as Himiko, which was found previously by the Subaru Telescope in 2009. "It is reasonable to find a protocluster near a massive object, such as Himiko. However, we're surprised to see th...
Astronomers use redshift measurements to determine an object's distance, and by extension its age. The bigger the redshift, the greater the distance. A redshift of 10.3 corresponds to a distance of about 13.2 billion light-years. That is, it's taken 13.2 billion years for the light from ...
The enigma of the oldest `nova': the central star and nebula of CK Vul CK Vul is classified as, amongst others, the slowest known nova, a hibernating nova or a very late thermal pulse object. Following its eruption in ad 1670,... M Hajduk,AA Zijlstra,HPAM Van,... - 《Monthly Noti...
Muja has lived through multiple bombing campaigns and several countries—all while never leaving a tiny pool in Belgrade's zoo for 83 years, making him the world's oldest captive alligator.
