Washington, D.C. – NASA says the hungriest of black holes are thought to gobble up so much surrounding material they put an end to the life of their host galaxy.
This feasting process is so intense that it creates a highly energetic object called a quasar – one of the brightest objects in the universe – as the spinning matter is sucked into the black hole’s belly. Now, researchers have found a galaxy that is surviving the black hole’s ravenous forces by continuing to birth new stars – about 100 Sun-sized stars a year.
Washington, D.C. – NASA says once you leave the majestic skies of Earth, the word “cloud” no longer means a white fluffy-looking structure that produces rain. Instead, clouds in the greater universe are clumpy areas of greater density than their surroundings.
Space telescopes have observed these cosmic clouds in the vicinity of supermassive black holes, those mysterious dense objects from which no light can escape, with masses equivalent to more than 100,000 Suns.
Pasadena, CA – Using NASA’s Hubble Space Telescope and a new observing technique, astronomers have found that dark matter forms much smaller clumps than previously known. This result confirms one of the fundamental predictions of the widely accepted “cold dark matter” theory.
All galaxies, according to this theory, form and are embedded within clouds of dark matter. Dark matter itself consists of slow-moving, or “cold,” particles that come together to form structures ranging from hundreds of thousands of times the mass of the Milky Way galaxy to clumps no more massive than the heft of a commercial airplane. (In this context, “cold” refers to the particles’ speed.)
Greenbelt, MD – NASA’s Hubble Space Telescope has found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

Nashville, TN – Tennessee Governor Bill Haslam, the Department of Economic and Community Development and LG Electronics Inc. officials announced the company will build a new home appliance manufacturing facility in Clarksville. The global manufacturer, with headquarters in South Korea, is a leader in appliances, electronics and mobile devices.
LG will invest $250 million in the facility, creating at least 600 new jobs in Montgomery County. The Clarksville facility will be LG’s first washing machine manufacturing operation in the United States. LG’s new Tennessee facility is expected to be the world’s most advanced production plant for washing machines.

Pasadena, CA – In a far-off galaxy, 12.4 billion light-years from Earth, a ravenous black hole is devouring galactic grub. Its feeding frenzy produces so much energy, it stirs up gas across its entire galaxy.
“It is like a pot of boiling water being heated up by a nuclear reactor in the center,” said Tanio Diaz-Santos of the Universidad Diego Portales in Santiago, Chile, lead author of a new study about this galaxy.

Greenbelt, MD – Astronomers using NASA’s Hubble Space Telescope have found that Markarian 231 (Mrk 231), the nearest galaxy to Earth that hosts a quasar, is powered by two central black holes furiously whirling about each other.
The finding suggests that quasars—the brilliant cores of active galaxies – may commonly host two central supermassive black holes, which fall into orbit about one another as a result of the merger between two galaxies.

Pasadena, CA – NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions — a phenomenon that had been suspected, but difficult to prove until now.
This discovery has given astronomers their first opportunity to measure the strength of these ultra-fast winds and prove they are powerful enough to inhibit the host galaxy’s ability to make new stars.
