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...

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...

WASHINGTON, July 31, 2014 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record-holder by 200 million years. http://photos.prnewswire.com/prnvar/20081007/38461LOGO These "lensing" galaxies are so massive that their gravity bends, magnifies, and distorts light from...

redOrbit Staff & Wire Reports - Your Universe Online For the first time, astronomers have been able to precisely measure the mass of the Milky Way, and have discovered that our solar system's home is actually smaller than previously believed. As reported this month in the journal Monthly Notices of the Royal Astronomical Society, researchers from the University of Edinburgh, the University of British Colombia, Carnegie Mellon University and NRC Herzberg Institute of Astrophysics...

Galaxy cluster MCS J0416.1–2403
2014-07-26 03:30:45

ESA/Hubble Information Center Stunning new observations from Frontier Fields Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing program, the map shows the amount and distribution of mass within MCS J0416.1–2403, a massive galaxy cluster found to be 160 trillion times the mass of the Sun. The detail in this mass map was made possible thanks...

optical fiber map of the cosmos

Verity Leatherdale, University of Sydney A new home-grown instrument based on bundles of optical fibers is giving Australian astronomers the first 'Google street view' of the cosmos — incredibly detailed views of huge numbers of galaxies. Developed by researchers at the University of Sydney and the Australian Astronomical Observatory, the optical-fiber bundles can sample the light from up to 60 parts of a galaxy, for a dozen galaxies at a time. By analyzing the light's spectrum...

April Flowers for redOrbit.com - Your Universe Online The Hubble Space Telescope is a joint project between NASA and the European Space Agency (ESA) that launched in 1990. Since then, it has returned thousands of images from its orbital position above the atmosphere, helping scientists to shed light on some of the mysteries of the cosmos. Hubble images prove that there is more to a galaxy than what first meets the eye. The telescope is able to look beyond the bright glow of a galaxy's...

Verity Leatherdale, University of Sydney The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved. The finding, by an international team of astronomers, including Professor Geraint Lewis from the University of Sydney's School of Physics, was announced July 18 in Nature. "Early in 2013 we announced our startling...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online While images of the Milky Way or Andromeda galaxies may dominate our mind’s image of what a galaxy looks like, the fact is that the largest objects in the Universe come in all shapes and sizes. In fact, most galaxies in the cosmos are known as dwarf galaxies. These systems are, as the name might suggest, smaller versions of the elliptical, spiral, and irregular galaxies that usually spring to mind. In many cases, these...

Image Caption: The Hubble Extreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed by humans. Each speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is estimated to contain more than 200 billion galaxies.

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...
