Small, ultrafaint "hobbit" galaxies recently found hovering around our Milky Way are comprised almost entirely of dark matter, a new study confirms. Dark matter is a mysterious substance scientists think accounts for most of the mass in the universe but that is invisible to current instruments. picked by AutumnLotus 2 years ago

Galaxies today are struggling to clump together against the incredible repulsive power of dark energy, hints a new survey of thousands of galaxies. Measuring this anti-clumping effect puts a new arrow in the quiver of cosmologists seeking to uncover the nature of the mysterious force. picked by deepchill 2 years ago

Astronomers have glimpsed the largest cluster of galaxies ever seen in the distant, early universe. The discovery of this far-off group, estimated to contain as much mass as a thousand large galaxies, offers further proof of the existence of the enigmatic force called dark energy. picked by AutumnLotus 1 year ago

Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of galaxies. picked by AutumnLotus 2 years ago

Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter. Mario Mateo and Matthew Walker measured the velocity of 6,804 stars in seven dwarf satellite galaxies of the Milky Way: Carina, Draco, Fornax, Leo I, Leo II, Sculptor and Sextans. They found that, contrary to what Newton's law of gravity predicts, stars in these galaxies do not move ... read full post picked by AutumnLotus 2 years ago

Distant ­supernovas (bright dots), captured by NASA’s Hubble telescope, open new vistas into the expansion history of the early universe. As early as 9 billion years ago, a mysterious repulsive force known as dark energy is seen exerting its influence.Even weirder than dark matter—the invisible stuff constituting most of the mass of the universe—is dark energy, a myst... read full post picked by rambler 3 years ago

Huge filaments of dark matter have been detected in a survey of thousands of distant galaxies. The discovery supports the idea that dark matter drove the formation of galaxies and larger cosmic structures and resolves a discrepancy in previous studies about how much dark matter the universe contains. picked by AutumnLotus 2 years ago

Two galaxy clusters collided with each other. The image gathered from visible light as well as the way that gravity effected the light provides striking evidence for dark matter and insight into its properties. More in depth info here in pdf form picked by 2manyusernames 1 year ago

Although Pink Floyd has never admitted to doing such a thing (except Roger, who stays quiet when asked), there are just a few points that should be examined. I guess you'll just have to come to your own conclusion. It's just the way it is with this band. But one thing this experiment does do is bring the theme of The Dark Side to life, whether it was intentional or not. picked by Mershaullk 3 years ago

In the early 1900s, Edwin Hubble made the startling discovery that our Milky Way galaxy is not alone. It is just one of many galaxies, or "island universes," as Hubble dubbed them, swimming in the sea of space. Now, a century later, NASA's Galaxy Evolution Explorer is helping piece together the evolution of these cosmic species. picked by AutumnLotus 2 years ago

About 70 percent is dark energy, and around 22 percent of the universe is made up of dark matter. Dark matter makes up a substantial part of the universe. Knowing what it is would answer a crucial question about the universe as a whole. picked by braveheart 3 years ago

SRON astronomer Floris van der Tak is the first to have observed acidic particulate clouds outside of our own Milky Way galaxy. He did this by focusing the James Clerk Maxwell Telescope, located on Hawaii, on two nearby Milky Way galaxies. Astronomers think that acidification inhibits the formation of stars and planets in the dust clouds. picked by AutumnLotus 2 years ago

Astronomers have produced a scientific gold mine of detailed, high-quality images of nearby galaxies that is yielding important new insights into many aspects of galaxies, including their complex structures, how they form stars, the motions of gas in the galaxies, the relationship of "normal" matter to unseen "dark matter," and many others. picked by AutumnLotus 2 years ago

Astronomers have argued for years over whether massive galaxies form from scratch, or by chunking together smaller galaxies. Lately, evidence is building for the latter theory, and a new study adds to the growing picture of galaxy formation as a clumpy affair. picked by AutumnLotus 1 year ago

When dark matter is destroyed, it leaves behind a burst of exotic particles, according to theory. Now scientists have found a possible signature of these remains. The discovery could help prove the existence of dark matter and reveal what it's made of. picked by AutumnLotus 8 months ago
