Brightest Galaxy

Brightest Galaxy Ever Discovered Could Contain 300 Trillion Suns

Scientists have discovered an ultra bright galaxy that while very far away at an estimated 12.5 billion light years, is still considered to be the most luminous galaxy every found in the universe and scientists believe it could contain more than 300 trillion suns.

Cause of Galactic Death: Strangulation

It's the ultimate whodunnit: what kills galaxies? A new study, published today in the journal Nature, names strangulation as the primary cause of galactic death.

Supernovae Dust ‘Goldmine’ Found at the Center of the Milky Way

One of the largest questions to date has been what building materials were present at the formation of our Milky Way galaxy? Astronomers have long theorized that the building material may have come from the death of supermassive stars, however, the galaxy-building dust is thought to burn up in a supernova like that. But now researchers are saying that may not be the case at all. In a new study published this week in the journal Science Express, researchers with Cornell University have made the first direct discovery of dust used to build the cosmos at the center of the Milky Way, and they believe it may have resulted from an ancient supernova.

Striking It Rich in Supernovae Dust at the Center of the Milky Way Galaxy

It’s a tough job sifting through the data and the haze of the center of the Milky Way galaxy, but some astronomers have to do it. The time-consuming job often means having to peer into the center with aid of multiple telescopes, all giving you a different perspective at a different wavelength. It can be job of countless hours, with little to no reward, but when researchers find even cosmic dust, their studies can strike it rich.

Is the Galaxy Bigger Than We Thought?

The Milky Way Galaxy is huge with our small solar system acting as just a grain of sand of the giant beach that is the galaxy. NASA previously estimated that the galaxy spans approximately 100,000 light years across. With each light year representing about 6 trillion miles, we are talking about an almost unimaginable distance. If you think that's large, new research now suggests that the Milky Way could be 50,000 light years larger than previously thought.

Could Dark Matter and Black Holes Cause the Swirl In Your Galaxy?

Ever seen a snapshot of the universe and wondered just how and what makes the beautiful swirling shapes that modern telescopes now let us see? Imagery of the Horsehead Nebula, the Pillars of Creation, and even the Rose Galaxies have captivated researchers and the public for decades, but finding exactly what causes space dust, planets and stars to conform in such elegant forms has often eluded astronomers studying the infinite wonders of space. But a new study conducted by researchers with the Harvard University Smithsonian Center for Astrophysics (CfA) reveals that the connection between collections of stars and the elliptical shapes of galaxies may have something to do with dark matter and the presence of black holes at the center of every galactic mass.

Light Signals Discovered by NASA Reveal The Merging of Two Black Holes

For the first time ever, scientists have seen an unusual light signal that appears to be repeating itself from a distant quasar. And no, before the thought crosses your mind, this is not a sign of extraterrestrial life, but rather a signal from two black holes. These signals are an indication of two supermassive black holes that are in the last stages of merging together.

Eons After the Big Bang, and 80 Years After It Was Proposed, Dark Matter Takes Form in Andromeda

For decades now, researchers have long believed that the ever-elusive dark matter has comprised roughly 80 percent of the entire universe’s mass. But in spite of advancing technology, taking astronomers past the moon to far off comets/planets and back, researchers have not yet been able to identify the existence of dark matter in our galaxy or any other, and have not yet been able to isolate the hypothetical invisible particles in Earth labs either. But in what appears to be a strange X-ray emission from nearby galactic clusters, two independent European research teams believe that they may have found the first true dark matter known to man—and it’s not too far away either.

Strange Andromeda Transmission May be First Sign of Dark Matter

While the ever elusive “dark matter” was first proposed by Swiss astronomer Fritz Zwicky in the early 1930s, a team of European scientists this week believe that they may have detected the first ever evidence of dark matter in mysterious photo emissions of the X-ray spectra, emitting from the Andromeda galaxy, the Draco dwarf galaxy, and other galactic clusters far outside our own solar system.
Mysterious Object in Milky Way

‘G2’ Gas Ball Survives Black Hole, and Researchers Say They Now Know Why

For years, astronomers have pondered the origins and the contents of the mysterious G2 object floating in the center of the Milky Way galaxy. Drifting towards the galaxy’s supermassive black hole, the passing cloud was thought to be composed entirely of hydrogen gas, giving it the nickname “G2”. But earlier this past summer researchers found that G2 had come in close contact with the black hole, and it survived—leading them on a new theory as to what the mysterious object could be.
