A peek at swirling matter around a giant black hole verifies that it is the source of a monstrous blast of energy thousands of light-years long, researchers say. Bursts of energy known as relativistic jets spew out matter at close to the speed of light. These jets can travel across an entire galaxy, suggesting they…
Astronomers have found a way to measure the size of a black hole. Supermassive black holes reside at the center of galaxies and have gravitational forces so strong that nothing, including light, can escape from being pulled into them. By combining the power of radio dishes in three different states into a super-telescope 2,000 times…
NASA’s Curiosity rover has found evidence that the area in Gale crater it is traveling through once had vigorously flowing water for perhaps thousands or millions of years. Scientists don’t know exactly how long ago this river would have flowed but it would likely be billions of years in the past. Several pieces of evidence…
Supermassive black holes appear to occupy the center of almost all galaxies. When they are actively swallowing matter, these black holes can power energetic jets that shine brighter than the entire rest of the galaxy, and can shoot matter free of it. Despite the mass and energy involved, however, the origin of these jets has…
The Hubble Space Telescope (HST) has produced one of its most extraordinary views of the Universe to date. Called the eXtreme Deep Field, the picture captures a mass of galaxies stretching back almost to the time when the first stars began to shine. But this was no simple point and snap – some of the…
Astronomers in Germany have developed an artificial intelligence algorithm to help them chart and explain the structure and dynamics of the universe around us with unprecedented accuracy. The team, led by Francisco Kitaura of the Leibniz Institute for Astrophysics in Potsdam, report their results in the journal Monthly Notices of the Royal Astronomical Society. Scientists…
Our galaxy — and the nearby Large and Small Magellanic Clouds as well — appears to be surrounded by an enormous halo of hot gas, several hundred times hotter than the surface of the Sun and with an equivalent mass of up to 60 billion Suns, suggesting that other galaxies may be similarly encompassed and…
Scientists can’t travel deep space the way Columbus sailed and charted the New World or Lewis and Clark mapped the west. But, researchers at Case Western Reserve University and two partnering institutions have found a possible way to map the spread and structure of the universe, guided by the light of quasars. The technique, combined…
Scientists have discovered the strongest evidence yet for a 13.2-billion-year old galaxy, a finding that provides a key piece of information about the universe’s early childhood. “This is the most distant (galaxy) identified with high confidence,” astronomer Wei Zheng, with Johns Hopkins University, told Discovery News. “If our current universe is a man of 70…
The Dark Energy Camera, a $40-million piece of equipment that represents a pinnacle of astronomical research, is now peering into the reddest reaches of the universe from its new home in Chile, and has seen “first light,” said Joshua Frieman, director of the survey. “That’s a major milestone,” Frieman told the Los Angeles Times in…
