Black Hole

Using the Subaru Telescope and W. M. Keck and Gemini observatories, astronomers have spotted three dual quasars — merging galaxy systems that have two supermassive black holes on a collision course with each other. SDSS J141637.44+003352.2, a dual quasar at a distance for which the light reaching us was emitted…

Some of the most perplexing topics in physics revolve around quantum theory. The quandary is seen most famously in the Schrödinger’s cat question and the issue of information loss in black hole evaporation. Richard Feynman said, “I think that I can safely say that nobody understands quantum mechanics.” Most physicists have just…

The Hubble Space Telescope has captured a glorious image of a galaxy with a very unusual shape. The so-called “Meathook galaxy” was home to a large supernova explosion that was observed just a few years ago.  Hubble continues to snap incredible images of the cosmos despite now being in service…

Quasars—accreting supermassive black holes—are paradoxically some of the brightest objects in the universe. Astronomers widely consider the energy from quasars to be the main driver in limiting the growth of massive galaxies. Scientists plan to use Webb to study the impact of three carefully selected quasars on their host galaxies…

Astronomers have observed cold, dense and high-velocity molecular gas outflowing from the center of our Milky Way Galaxy. The presence of this gas is puzzling, because neither Sagittarius A*, a supermassive black hole in the Milky Way’s center, at its current level of activity nor star formation in the inner…

A series of ‘black dwarf’ supernovae will be the last astrophysical events to occur in our Universe prior to the so-called heat death, when the Universe will be populated only by black holes and ‘frozen’ white dwarfs, according to a paper by Illinois State University theoretical physicist Matt Caplan. In…

By embracing the tenets of the sub-genre — deadly combat, rewarding exploration, and a gameplay loop designed around learning from failure — and adding…

Astronomers have discovered what can happen when a giant black hole does not intervene in the life of a galaxy cluster. Using NASA’s Chandra X-ray Observatory and other telescopes they have shown that passive black hole behavior may explain a remarkable torrent of star formation occurring in a distant cluster…

Supermassive black holes are among the most exciting and puzzling objects in the universe. These are the giant, massive bodies that sit at the heart of most, perhaps all, galaxies. Indeed, they may be the seeds from which all galaxies grow. Supermassive black holes are at least a hundred thousand…

TAU chalks up the possibility that a star "got too close to the dining table," causing the disruption - being devoured in the process. A supermassive black hole with millions to billions times the mass of our sun is seen in an undated NASA artist's concept illustration. (photo credit: REUTERS/NASA/JPL-CALTECH/HANDOUT)…
