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 of 430,000 Light Years appears highly flattened, either the shape of a disk or of a cigar. picked by AutumnLotus 2 years ago tags Hercules dwarf galaxy flat large binocular telescope |

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 0 comments edit related share plime.com |
The Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth that is stuffing itself with smaller galaxies caught like flies in a web of gravity. The galaxy is so far away that astronomers are seeing it as it looked in the early formative years of the Universe, only 2 billion years after the Big Bang. picked by 2manyusernames 3 years ago 2 comments edit related share science |
Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide – two ingredients that build life-forming amino acids – in a galaxy some 250 million light years away. picked by AutumnLotus 2 years ago 2 comments edit related share science |
Edwin Hubble once called IC 10 “one of the most curious objects in the sky,” and new observations of the extremely faint, lightweight dwarf galaxy are giving scientists new clues about how populations of stars are born. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
This new guide for astronomers, known as the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) shows the Milky Way in submillimetre-wavelength light (between infrared light and radio waves). Images of the cosmos at these wavelengths are vital for studying the birthplaces of new stars and the structure of the crowded galactic core. picked by AutumnLotus 5 months ago 0 comments edit related share science |

The Large Binocular Telescope on Mount Graham, Ariz., has taken celestial images using its twin side-by-side, 8.4-meter (27.6 foot) primary mirrors together, achieving first "binocular" light. picked by AutumnLotus 2 years ago 0 comments edit related share science |
Newborn stars shine like celestial sparklers in a new portrait of the nearby Triangulum Galaxy – the most detailed ultraviolet image of a galaxy ever taken. Astronomers will use the image, taken by NASA's Swift telescope, to create an "age map" of the galaxy's components to understand how galaxies evolve over time. picked by AutumnLotus 2 years ago 2 comments edit related share science |
The Very Large Telescope has taken one of the best ever images of two galaxies locked in a slow motion, disruptive collision, scientists say. 0 comments edit related share scienceThe image has also given astronomers a peak at an unusual exploding star in the same area of the sky. picked by AutumnLotus 9 months 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 0 comments edit related share plime.com |
An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. Named the Spitzer Adaptation of the Red-sequence Cluster Survey, "SpARCS" detects galaxy clusters using deep ground-based optical observations from the CTIO 4m and CFHT 3.6m telescopes, combined with Spitzer Space Telescope infrar... read full post picked by AutumnLotus 5 months ago 0 comments edit related share science |
Dubbed SDSSJ0737+3216, the just discovered galaxy is 100 times lighter than our own Milky Way and is the smallest galaxy ever identified at that distance. It is about half the size and approximately one-tenth the "weight" of typical small galaxies found closer to Earth. picked by julea 2 years ago 4 comments edit related share plime.com |
The galaxy, as large as the Milky Way, is about 12.8 billion light-years away and harbors a supermassive black hole that contains at least a billion times as much matter as our sun. The universe is about 13.7 billion years old, and faraway objects like this are seen as they existed near the dawn of time, their light just now arriving at Earth. picked by kakana 3 months ago 1 comments edit related share science |

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 0 comments edit related share plime.com |
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 0 comments edit related share science |
The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much farther away than previously thought. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
UC Irvine scientists have discovered a cluster of galaxies in a very early stage of formation that is 11.4 billion light years from Earth – the farthest of its kind ever to be detected. These galaxies are so distant that the universe was in its infancy when their light was emitted. picked by AutumnLotus 2 years ago 0 comments edit related share science |
Astronomers have identified a type of galaxy that represents a "missing link" in our understanding of the Universe. Spiral and elliptical galaxies used to be known exclusively as "blue" and "red", respectively. But two studies show that one in five galaxies is a red spiral. picked by AutumnLotus 1 year ago 0 comments edit related share science |

A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early universe developed either much faster or in a different way from what astronomers have thought. The galaxy is forming the equivalent of 4,000 Suns a year. This is a thousand times more violent than our own Milky Way galaxy. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |
