redOrbit Staff & Wire Reports - Your Universe Online An international team of astronomers studying the satellite galaxies surrounding Andromeda has for the first time observed the remnant of a merger between two low-mass dwarf galaxies, according to new research published online Sunday in the journal Nature. The study authors, who hail from the Niels Bohr Institute at the University of Copenhagen, the University of Cambridge’s Institute of Astronomy and the Max Planck Institute...

ESA Releases Hubble Image Of Messier 83, A Galaxy With Two Hearts
2014-01-10 06:45:29

April Flowers for redOrbit.com - Your Universe Online A new image released from the ESA and NASA jointly-operated Hubble Space Telescope features the spiral galaxy Messier 83, also known as the Southern Pinwheel Galaxy. Messier 83, which is one of the largest and closest barred spiral galaxies to us, has hosted a large number of supernova explosions, and is thought to have a double nucleus at its core. The image was released this week at the 223rd meeting of the American Astrophysical...

Study Of Massive Stars Shows Milky Way's Missing Arms
2013-12-17 08:54:09

University of Leeds A 12-year study of massive stars has reaffirmed that our Galaxy has four spiral arms, following years of debate sparked by images taken by NASA's Spitzer Space Telescope that only showed two arms. The new research, which is published online today [17 December] in the Monthly Notices of the Royal Astronomical Society, is part of the RMS Survey, which was launched by academics at the University of Leeds. Astronomers cannot see what our Galaxy, which is called the...

Andromeda Galaxy Image Processed By The HSC Data Analysis Software
2013-08-06 11:44:39

Kavli Institute for the Physics and Mathematics of the Universe Today, researchers at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) released the first image of the Andromeda Galaxy (M31) processed with the data analysis software developed for the Subaru Telescope's Hyper Suprime-Cam (HSC). The HSC project's 'first light' was announced last week (A New View on the Origin of Dark Matter and Dark Energy - Image of M31 Heralds the Dawn of HSC). Researchers at...

New Weapon Hunt For Dark Matter Energy
2013-08-02 13:06:59

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for dark matter - and the even more mysterious dark energy - has both captivated and frustrated the minds of cosmologists and astronomers. There are the obvious reasons: by definition these phenomenon are difficult, if not impossible, to observe directly, and their effects can often be so subtle that making precise enough measurements proves a technical challenge. To overcome these difficulties, a team from the...

Black Hole Count Keeps Growing For The Andromeda Galaxy
2013-06-13 06:10:47

April Flowers for redOrbit.com - Your Universe Online Astronomers have discovered an unprecedented number of black holes in the Andromeda Galaxy (M31), one of the Milky Way´s nearest cosmic neighbors, using data from NASA´s Chandra X-ray Observatory. By analyzing more than 150 Chandra observations taken over 13 years, the research team has identified 26 black hole candidates. This is the largest number discovered to date in a galaxy outside our own. Many scientists consider...

WASHINGTON, June 12, 2013 /PRNewswire-USNewswire/ -- Using data from NASA's Chandra X-ray Observatory, astronomers have discovered an unprecedented bonanza of black holes in the Andromeda Galaxy, one of the nearest galaxies to the Milky Way. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Using more than 150 Chandra observations, spread over 13 years, researchers identified 26 black hole candidates, the largest number to date, in a galaxy outside our own. Many consider...

Astronomers Size Up The Smallest Galaxy In The Universe
2013-06-10 11:54:04

Lee Rannals for redOrbit.com - Your Universe Online University of California, Irvine scientists reported on Monday that they have measured the least massive galaxy in the known universe. The researchers wrote in The Astrophysical Journal that the tiny dwarf galaxy, Segue 2, only holds a mere 1,000 stars within its realm. Their findings offer clues about how iron, carbon and other elements help form human life. “Finding a galaxy as tiny as Segue 2 is like discovering an elephant...

Earth's Neighborhood In The Milky Way Sits On Spiral Arm, Not Spur
2013-06-03 14:49:23

Lee Rannals for redOrbit.com — Your Universe Online New research using the ultra-sharp radio vision of the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) has determined that we live in a more upscale neighborhood in our galaxy than previously thought. Considering we reside inside the Milky Way, it is tough for scientists to predict exactly where in our galaxy we sit. Astronomers are able to get a bird's-eye view of other galaxies, but we must use different...

Ring Galaxy -- A subclass of interacting galaxies, ring galaxies, provides a unique laboratory for studying unusually large bursts of non-nuclear star formation. The rings in these systems are often large (10s of kiloparsecs) and contain what appear to be associations of giant H{\small II} regions. As a basis for future modeling of star forming regions in observed ring galaxies we present a series of combined n-body/gas numerical experiments on ring formation and evolution. Three...

Cartwheel Galaxy -- Located 500 million light-years away in the constellation Sculptor, the Cartwheel Galaxy looks like a wagon wheel. The galaxy's nucleus is the bright object in the center of the image; the spoke-like structures are wisps of material connecting the nucleus to the outer ring of young stars. This close-up image of the galaxy's nucleus reveals the comet-like knots of gas. These knots are mostly confined to the core's left side and appear as white streaks inside the blue...

Andromeda Galaxy -- The Andromeda Galaxy, also known as M31, or the object 31 on the catalog of Messier, is the other giant spiral galaxy in the Local Group, together with our galaxy, the Milky Way. It is at a distance of approximately 2.36 million light years or 725 kpc, in the direction of the constellation Andromeda, and it will probably merge in the future with our galaxy, to form a giant elliptical. With a mass of about 1.5 times more than the Milky Way, it is the dominant galaxy...
