(Space Fellowship) M31: The Andromeda Galaxy

What is the nearest major galaxy to our own Milky Way Galaxy? Andromeda. In fact, our Galaxy is thought to look much like Andromeda. Together these two galaxies dominate the Local Group of galaxies. The diffuse light from Andromeda is caused by the hundreds of billions of stars that compose it. The several distinct stars that surround Andromeda's image are actually stars in our Galaxy that are well in front of the background object. Andromeda is frequently referred to as M31 since it is the  [...]
  

(Space Fellowship) The Seagull Nebula

A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker - The Seagull Nebula. This portrait of the cosmic bird covers a 1.6 degree wide swath across the plane of the Milky Way, near the direction of Sirius, alpha star of the constellation Canis Major. Of course, the region includes objects with other catalog designations: notably NGC 2327, a compact, dusty emission region with an embedded massive star that forms the [...]

(Discovery News) Beyond Sunday's 'Supermoon': Lunar Perigee Science

You'll probably hear a lot about a 'supermoon' over the next few months. This is not a term that astronomers use, but here are some facts about what will actually happen.   

(Space Fellowship) Puppis A Supernova Remnant

Driven by the explosion of a massive star, supernova remnant Puppis A is blasting into the surrounding interstellar medium about 7,000 light-years away. At that distance, this colorful telescopic field based on broadband and narrowband optical image data is about 60 light-years across. As the supernova remnant expands into its clumpy, non-uniform surroundings, shocked filaments of oxygen atoms glow in green-blue hues. Hydrogen and nitrogen are in red. Light from the initial supernova itself, [...]
  

(Space Fellowship) NASA Concludes Series of Engine Tests for Next-Gen Rocket

NASA has completed the first developmental test series on the RS-25 engines that will power the agency’s new Space Launch System (SLS) rocket on missions deeper into space than ever before. The test series wrapped up Thursday with a seventh hot fire test of a developmental RS-25 engine on the A-1 Test Stand at NASA’s Stennis Space Center in Bay St. Louis, Mississippi. The test ran for a full-duration 535 seconds. “The completion of this test series is an important step in getting  [...]
  

(Space Fellowship) Spacecraft Moving to New Port Before New Crew Launches

The six-person Expedition 44 space station crew is getting ready to expand to nine people next week. A docked Soyuz vehicle will be moved early Friday morning making room for a new Soyuz spacecraft carrying Sergei Volkov, a new Expedition 45 crew member, and two visiting crew members Andreas Mogensen and Aidyn Aimbetov. The orbital residents will shift their schedules tonight as One-Year crew members Scott Kelly and Mikhail Kornienko join Commander Gennady Padalka for a short Soyuz ride from  [...]
  

(Space Fellowship) Hubble Finds That the Nearest Quasar Is Powered by a Double Black Hole

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 that fall into orbit about one another as a result of the merger between two galaxies. Like a pair of whirling skaters, the black-hole duo generates [...]
  

(ScienceDaily) Astrophysicist find supermassive black holes in quasar nearest Earth

Astrophysicists have found two supermassive black holes in Markarian 231, the nearest quasar to Earth. The discovery of two supermassive black holes -- one larger one and a second, smaller one -- are evidence of a binary black hole and suggests that supermassive black holes assemble their masses through violent mergers.   

(Space Fellowship) Interstellar Seeds Could Create Oases of Life

We only have one example of a planet with life: Earth. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars. If we find alien life, new questions will arise. For example, did that life arise spontaneously? Or could it have spread from elsewhere? If life crossed the vast gulf of interstellar space long ago, how would we tell? New research by Harvard astrophysicists shows that if life can travel between the stars (a process called p [...]
  

(Discovery News) Could Alien Life Spread 'Like a Virus' to the Stars?

As astronomical techniques become more advanced, a team of astrophysicists think they will be able to not only detect the signatures of alien life in exoplanetary atmospheres, but also track its relentless spread throughout the galaxy.   

(ScienceDaily) Interstellar seeds could create oases of life

Astrophysicists now show that if life can travel between the stars (a process called panspermia), it would spread in a characteristic pattern that we could potentially identify.

(ScienceDaily) Discovering dust-obscured active galaxies as they grow

Astronomers have performed an extensive search for Dust Obscured Galaxies (DOGs). The research group discovered 48 DOGs, and has measured how common they are. Since DOGs are thought to harbor a rapidly growing black hole in their centers, these results give us clues for understanding the evolution of galaxies and supermassive black holes.

(Space Fellowship) Discovering Dust-Obscured Active Galaxies as They Grow

A group of researchers from Ehime University, Princeton University, and the National Astronomical Observatory of Japan (NAOJ) among others has performed an extensive search for Dust Obscured Galaxies (DOGs) using data obtained from the Subaru Strategic Program with Hyper Suprime-Cam (HSC). HSC is a new wide-field camera mounted at the prime focus of the Subaru Telescope and is an ideal instrument for searching for this rare and important class of galaxy. The research group discovered 48 DOGs [...]
  

(Space Fellowship) The Large Cloud of Magellan

The 16th century Portuguese navigator Ferdinand Magellan and his crew had plenty of time to study the southern sky during the first circumnavigation of planet Earth. As a result, two fuzzy cloud-like objects easily visible to southern hemisphere skygazers are known as the Clouds of Magellan, now understood to be satellite galaxies of our much larger, spiral Milky Way galaxy. About 160,000 light-years distant in the constellation Dorado, the Large Magellanic Cloud (LMC) is seen here in a rema [...]

(ScienceDaily) Self-healing material could plug life-threatening holes in spacecraft

For astronauts living in space with objects zooming around them at 22,000 miles per hour like rogue super-bullets, it's good to have a backup plan. Although shields and fancy maneuvers could help protect space structures, scientists have to prepare for the possibility that debris could pierce a vessel. One team reports on a new material that heals itself within seconds and could prevent structural penetration from being catastrophic.

New research predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos.   

(ScienceDaily) Twin Jet Nebula: The wings of the butterfly

The shimmering colours visible in this NASA/ESA Hubble Space Telescope image show off the remarkable complexity of the Twin Jet Nebula. The new image highlights the nebula's shells and its knots of expanding gas in striking detail. Two iridescent lobes of material stretch outwards from a central star system. Within these lobes two huge jets of gas are streaming from the star system at speeds in excess of one million kilometers per hour.
