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 ...
An oldest-first generational garbage collector leaves intact the most recently allocated object space, and instead collects the remaining, older objects. Because these older objects have had more time to die, an oldestfirst copying collector will generally do less copying that a traditional generational...
"Redshift" is a measure of how much the expansion of space has stretched an object's light to longer (or redder) wavelengths. Light from objects moving away from us shifts to the red end of the spectrum as its wavelengths are stretched. The shift, known as the Doppler phenomenon, is ...

Previously, the oldest traces of this kind found dated to approximately 600 million years ago: the Ediacaran period, also characterized by a peak in dioxygen and a proliferation in biodiversity. Scale bar: 1 cm. Credit: A. El Albani / IC2MP / CNRS - Université de Poitiers ...

This research focuses on the names that were used for a short time or disappeared together with the object around which they signified the space. The sources of this work were the four oldest city books of Lviv: the book of the council and the bench court, two books of income and ...
