Black hole spin cranks-up radio volume

Science Daily - Fri, 01/12/2018 - 9:59am
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets.

X-ray navigation could open up new frontiers for robotic spacecraft

Science Daily - Thu, 01/11/2018 - 10:39pm
In a technology first, a team of engineers has demonstrated fully autonomous X-ray navigation in space -- a capability that could revolutionize NASA's ability in the future to pilot robotic spacecraft to the far reaches of the solar system and beyond.

Supermassive black hole caught burping — twice

Science Daily - Thu, 01/11/2018 - 4:29pm
Astronomers have caught a supermassive black hole in a distant galaxy snacking on gas and then "burping" — not once, but twice.

Magnified and stretched out image of extremely distant galaxy

Science Daily - Thu, 01/11/2018 - 4:29pm
An intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing.

Archeology of our Milky Way's ancient hub

Science Daily - Thu, 01/11/2018 - 4:29pm
A new analysis of about 10,000 normal Sun-like stars in the Milky Way's bulge reveals that our galaxy’s hub is a dynamic environment of variously aged stars zipping around at different speeds.

No planets needed for rings around stars: Disk patterns can self-generate

Science Daily - Thu, 01/11/2018 - 3:50pm
A new study shows rings, arcs and spirals in disks around stars may not be caused by planets. They may self-generate.

Brown dwarfs found sprinkled among newborn stars in Orion Nebula

Science Daily - Thu, 01/11/2018 - 3:50pm
Astronomers have uncovered the largest known population of brown dwarfs sprinkled among newborn stars in the Orion Nebula.

Citizen scientists discover five-planet system

Science Daily - Thu, 01/11/2018 - 2:40pm
In its search for exoplanets -- planets outside of our solar system -- NASA's Kepler telescope trails behind Earth, measuring the brightness of stars that may potentially host planets. The instrument identifies potential planets around other stars by looking for dips in the brightness of the stars that occur when planets cross in front of, or transit, them. Typically, computer programs flag the stars with these brightness dips, then astronomers look at each one and decide whether or not they truly could host a planet candidate.

Faint galactic glow: Intriguing organic molecule benzonitrile in interstellar space

Science Daily - Thu, 01/11/2018 - 2:16pm
Astronomers have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and truly massive ones known as polycyclic aromatic hydrocarbons. This discovery is a vital clue in a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies.

Astronomers to build space telescope to explore nearby stars

Science Daily - Wed, 01/10/2018 - 10:05pm
A new mission will launch a small satellite telescope into space to study the environment in other solar systems around the Galaxy's most common type of star.

A repeating fast radio burst from an extreme environment

Science Daily - Wed, 01/10/2018 - 5:14pm
New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the source's environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power.

Swarm of hydrogen clouds flying away from center of the Milky Way

Science Daily - Wed, 01/10/2018 - 4:32pm
Astronomers have discovered what appears to be a grand exodus of more than 100 hydrogen clouds streaming away from the center of the Milky Way and heading into intergalactic space.

NASA's newly renamed Swift Mission spies a comet slowdown

Science Daily - Wed, 01/10/2018 - 3:04pm
NASA's Swift spacecraft, now renamed the Neil Gehrels Swift Observatory after the mission's late principal investigator, has detected the most dramatic change in a comet's rotation ever seen.

New stellar streams confirm 'melting pot' history of the galaxy

Science Daily - Wed, 01/10/2018 - 2:13pm
Where do the stars in our Galaxy come from? All the stars we see in the night-time sky belong to our Milky Way galaxy, and while most stars were likely born here, in the Milky Way, many appear to have originated in other galaxies and migrated to our shores. Tell-tale evidence comes from streams of stars created when small galaxies interact with the Milky Way.
