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 11 months 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 1 year 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 2 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 7 months 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 12 months ago 0 comments edit related share plime.com |

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 6 months ago 2 comments edit related share science |

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 10 months ago 0 comments edit related share plime.com |

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 11 months ago 4 comments edit related share plime.com |

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 9 months ago 0 comments edit related share plime.com |

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 10 months 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 5 months ago 0 comments edit related share science |

This Chandra X-ray Observatory image shows the debris of a massive star explosion in the Large Magellanic Cloud, a small galaxy about 160,000 light years from Earth. The supernova remnant (SNR) shown here, N132D, is the brightest in the Magellanic clouds, and belongs to a rare class of oxygen-rich remnants. Most of the oxygen that we breathe on Earth is thought to have come from explosions similar... read full post picked by AutumnLotus 5 months ago 0 comments edit related share science |

Orphaned stars are being born in a vast tail of material stretching behind a faraway galaxy. The finding is evidence that orphaned stars — those not orbiting the center of a galaxy in normal fashion — are much more common than thought. picked by AutumnLotus 11 months ago 0 comments edit related share plime.com |

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 8 months ago 0 comments edit related share plime.com |

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 7 months ago 0 comments edit related share science |

Astronomers have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs were siblings orbiting each other. They slowly spiraled inward until they merged, touching off a titanic explosion. CfA observations show the strongest evidence yet of what was, until now, a purely theoretical mechanism for creating a supernova. picked by AutumnLotus 10 months ago 2 comments edit related share plime.com |

More than 800,000 snapshots from NASA's Spitzer Space Telescope have been stitched together to create a new "coming of age" portrait of stars in our inner Milky Way galaxy. The image depicts an area of sky 120 degrees wide by two degrees tall. High-res zoomable image. picked by AutumnLotus 3 months ago 0 comments edit related share science |
