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

Two galaxies perform an intricate dance in this new Hubble Space Telescope image. The galaxies, containing a vast number of stars, swing past each other in a graceful performance choreographed by gravity. picked by AutumnLotus 2 years ago

Using ESO's Very Large Telescope, an international team of astronomers has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy. picked by AutumnLotus 2 years ago

Galaxies tend to give birth to their stars on the road, while travelling down intergalactic highways towards cosmic cities called galaxy clusters, new Spitzer Space Telescope observations reveal. Galaxies in relatively empty regions of the universe flock towards densely populated galaxy clusters, attracted there by the clusters' gravity. picked by AutumnLotus 2 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

Astronomers from SRON Netherlands Institute for Space Research have discovered a new cluster of galaxies, hidden behind a previously identified cluster of galaxies. The recently exposed cosmic giant is apparently just as bright as the first group, but is six times further away. The astronomers made the discovery as part of an international team using the space telescope XMM-Newton. picked by AutumnLotus 2 years 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

An image based on data taken with ESO's Very Large Telescope reveals a triplet of galaxies intertwined in a cosmic dance. The three galaxies, catalogued as NGC 7173 (top), 7174 (bottom right) and 7176 (bottom left), are located 106 million light-years away towards the constellation of Piscis Austrinus (the 'Southern Fish'). picked by AutumnLotus 2 years ago

A new image from NASA's Spitzer Space Telescope offers a rare view of an imminent collision between the cores of two merging galaxies, each powered by a black hole with millions of times the mass of the sun. picked by AutumnLotus 9 months ago

Dusty infrared galaxies are cosmic "nurseries" for some of the universe's hottest young stars -- and new research from NASA's Spitzer Space Telescope shows that when the universe was approximately six billion years old, these galaxies packed into the densest "zip codes" in space. Astronomers hope that this latest finding will give them insights into why the modern universe look... read full post picked by AutumnLotus 2 years ago

Through some of the very first scientific observations with the brand-new Large Binocular Telescope (LBT) in Arizona, astronomers has found that a recently discovered tiny companion galaxy to our Milky Way, named the Hercules Dwarf Galaxy, has truly exceptional properties: while basically all of its known peers in the realm of these tiny dwarf galaxies are rather round, this galaxy at a distance o... read full post 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

The Crip Walk originated in the early 1980s in South Central Los Angeles as a symbol for Crips. This is not a dance, but rather a walk done by Crips. The main focus of Crip Walking was to represent your hood, area code, or gang by throwing up signs with your hands or spelling out a set of words. picked by SunSeven 3 years ago

A newly discovered dwarf galaxy in the Local Group has been found to have formed in a region of space far from our own and is falling into our system for the first time in its history. picked by AutumnLotus 3 years ago

Dwarf galaxies orbiting the Milky Way are breaking the laws of physics, prompting another modification of Newton's theory of gravitation. picked by AutumnLotus 7 months ago

Astronomers have discovered new tidal debris stripped away from colliding galaxies. New debris images are of special interest since they show the full history of galaxy collisions and resultant starburst activities, which are important in 'growing' galaxies in the early Universe. picked by AutumnLotus 6 months 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

The most energetic particles in the universe likely come from enormous black holes nestled in the restless hearts of traumatized galaxies, scientists say. Where these cosmic "bullets" originated has been a source of much speculation, with scientists proposing everything from gamma ray bursts to decaying dark matter. picked by AutumnLotus 2 years ago
