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...

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...

Clouds Of Hydrogen Gas Found In Our Galactic Backyard
2013-05-08 12:37:51

Watch the video “Intergalactic Clouds Lurk Between Nearby Galaxies" John P. Millis, PhD for redOrbit.com — Your Universe Online As we gaze into space beyond the confines of our own Milky Way, we see a Universe filled with galaxies. But what scientists have come to realize is that the emptiness that spans between these giant pools of stars is not empty at all, but rather is filled with massive amounts of gas. In fact, these gas reservoirs can sometimes outweigh the galaxies...

Astronomers Asking Volunteers To Help Find 'Space Warps'
2013-05-08 12:46:13

[WATCH VIDEO: Space Warps Gravitational Lensing Animation] Lee Rannals for redOrbit.com — Your Universe Online Volunteers are being summoned to help astronomers find "space warps," leading to the discovery of faraway objects. Space warps, more commonly known as "gravitational lenses," allow objects in space to act as a giant lens to other objects even farther away. Studies have found that the human brain is much better at identifying lenses than current computer algorithms, so...

Stellar Motions In Outer Halo Reveal Evidence Of Milky Way Evolution
2013-02-22 11:40:05

April Flowers for redOrbit.com - Your Universe Online Astronomers using NASA's Hubble Space Telescope to peer deep into the vast stellar halo that envelopes our galaxy have uncovered tantalizing evidence for the possible existence of a shell of stars that are a relic of cannibalism by our Milky Way. For the first time ever, Hubble was used to gain precise measurements of the sideways motion of a small sample of stars located far from the galaxy's center. The unusual lateral motion of...

Astronomers Discover Structure 4 Billion Light Years Across - Largest Known In Universe
2013-01-11 13:29:21

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have reportedly discovered the largest known structure in the universe — a formation so massive it would take a vehicle that was moving at light speed roughly four billion light years to cross it, the Royal Astronomical Society (RAS) announced on Thursday. The structure is a large quasar group (LQG), or a formation that contains the nuclei of galaxies from the earliest days of the universe´s existence. These...

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...
