Chuck Bednar for redOrbit.com - Your Universe Online Using a new mapping technique that takes into account the motions of nearby galaxies, and not just their distances, researchers from the University of Hawaii have discovered that the Milky Way resides on the outer edge of a massive, previously undetected supercluster of galaxies that they have dubbed Laniakea. Laniakea, a moniker created from the words meaning “immeasurable heaven” in Hawaiian, spans 520 million light-years in...

NASA/Space Telescope Science Institute/ESA Astronomers have for the first time caught a glimpse of the earliest stages of massive galaxy construction. The building site, dubbed “Sparky,” is a dense galactic core blazing with the light of millions of newborn stars that are forming at a ferocious rate. The discovery was made possible through combined observations from NASA’s Hubble and Spitzer space telescopes, the W.M. Keck Observatory in Mauna Kea, Hawaii, and the European Space...

Rebecca Caygill, University College London New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built. The study published today in The Astrophysical Journal Letters by UCL cosmologists Dr Andrew Pontzen and Dr Hiranya Peiris (both UCL Physics & Astronomy), together with collaborators at Princeton and Barcelona Universities, shows how forthcoming astronomical surveys will reveal...

Chuck Bednar for redOrbit.com - Your Universe Online Using a battery of observatories that included the Atacama Large Millimeter/submillimeter Array (ALMA) and the Hubble Space Telescope, an international team of astronomers has obtained the best view to date of a collision between two galaxies that took place when the universe was just a fraction of its current age. According to ESA, the team also utilized a gravitational lens to magnify galaxy HATLAS J142935.3-002836, revealing...

redOrbit Staff & Wire Reports - Your Universe Online The Wide Field Imager at the ESO’s La Silla Observatory in Chile has captured new images of two dramatic regions of star formation in the southern Milky Way, one of which features a Wolf–Rayet multiple star system. [ Watch: Zooming In On Star Formation In The Southern Milky Way ] Wolf-Rayet stars, the ESO explains, are at an advanced stage of stellar evolution and begin with a mass approximately 20 times that of the sun....

Arecibo gas bridge
2014-08-08 06:43:44

Royal Astronomical Society Astronomers and students have found a bridge of atomic hydrogen gas 2.6 million light years long between galaxies 500 million light years away. They detected the gas using the William E. Gordon Telescope at the Arecibo Observatory, a radio astronomy facility of the US National Science Foundation sited in Puerto Rico. The team published their results Thursday in a paper in Monthly Notices of the Royal Astronomical Society. The stream of atomic hydrogen gas is...

Messier 33
2014-08-06 11:14:16

ESO Messier 33, otherwise known as NGC 598, is located about three million light-years away in the small northern constellation of Triangulum (The Triangle). Often known as the Triangulum Galaxy it was observed by the French comet hunter Charles Messier in August 1764, who listed it as number 33 in his famous list of prominent nebulae and star clusters. However, he was not the first to record the spiral galaxy; it was probably first documented by the Sicilian astronomer Giovanni Battista...

farthest cosmic lens

redOrbit Staff & Wire Reports - Your Universe Online A massive new elliptical galaxy unexpectedly discovered using NASA’s Hubble Space Telescope is the most distant lensing galaxy ever discovered, officials from the US space agency confirmed in a statement Thursday. Lensing galaxies essentially act as a cosmic magnifying glass, and are large enough that their gravity can bend and distort light in such a way that they can make it easier to detect more distant objects in space....

Research Finds Numerous Unknown Jets From Planetary Nebulae And Young Stars
2014-08-01 03:48:51

University of Kent For many years astronomers have known that young 'protostars' drive supersonic jets of gas from their north and south poles. However, this is the first time that so many of them have been detected at once. The results come from a five year survey undertaken with the UK Infra-Red Telescope and are expected to prompt significant changes in the understanding of the planetary nebulae population in the Galaxy, as well as the properties of jets ejected from young forming...

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 × 1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...

The two Magellanic Clouds (or Nubeculae Magellani), composed of the Large Megellanic Cloud and the Small Magellanic Cloud, are irregular dwarf galaxies visible in the southern hemisphere. They are members of our Local Group and orbit the Milky Way galaxy. Persian astronomer Al Sufi, in 964, was the first to have written anything about the Magellanic Clouds proving they have been known since early time amongst the Middle East peoples. Sufi, in his Book of Fixed Stars, calls the clouds...

The M96 Group (also known as the Leo I Group), one of many in the Virgo Supercluster, is located within the Leo constellation and contains between 8 and 24 galaxies, including three Messier objects. The Leo Triplet, which is physically near M96 Group, and M96 may actually be separate parts of a much larger group.

The M81 Group, containing the well known galaxies Messier 81 and Messier 82, is a group of galaxies within the constellation Ursa Major. Along with Messier 81 and 82 are several other galaxies with apparent brightness. The center, located at an approximate distance of 3.6 Mpc, is one of the nearest groups to the Local Group. The total estimated mass of the group is (1.03 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
