Smith Cloud Survives Galactic Collision Thanks To Full Dark-matter Facket
2014-05-23 03:44:33

National Radio Astronomy Observatory Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis of data from the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT). Astronomers believe that without this protective shell, the high-velocity cloud (HVC) known as the Smith Cloud would have disintegrated long ago when it first collided with the disk...

Cosmic Clumps Cast Darkest Shadows Ever Recorded
2014-05-22 03:51:02

Whitney Clavin, NASA's Jet Propulsion Laboratory Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded. Infrared observations from NASA's Spitzer Space Telescope of these blackest-of-black regions paradoxically light the way to understanding how the brightest stars form. The clumps represent the darkest portions of a huge, cosmic cloud of gas and dust located about 16,000 light-years away. A new study takes advantage of the...

A Star Cluster In The Wake Of Carina
2014-05-21 03:14:10

[ Watch The Video: Panning Across The Colorful Star Cluster NGC 3590 ] ESO NGC 3590 is a small open cluster of stars around 7500 light-years from Earth, in the constellation of Carina (The Keel). It is a gathering of dozens of stars loosely bound together by gravity and is roughly 35 million years old. This cluster is not just pretty; it is very useful to astronomers. By studying this particular cluster — and others nearby — astronomers can explore the properties of the spiral...

redOrbit Staff & Wire Reports - Your Universe Online A team of astronomers have identified what is believed to be the sibling of our sun – a star thought to have been born from the same cloud of gas as the one that provides our solar system with light and warmth. According to Deborah Netburn of the Los Angeles Times, the sun’s so-called long-lost brother is slightly bigger and has a somewhat hotter surface temperature than the star around which the Earth orbits. However, an...

Magnetic Fingerprint Of Our Galaxy Revealed By Planck
2014-05-06 03:21:32

ESA Our Galaxy's magnetic field is revealed in a new image from ESA's Planck satellite. This image was compiled from the first all-sky observations of 'polarized' light emitted by interstellar dust in the Milky Way. Light is a very familiar form of energy and yet some of its properties are all but hidden to everyday human experience. One of these – polarization – carries a wealth of information about what happened along a light ray's path, and can be exploited by astronomers....

elliptical galaxy M87
2014-04-30 12:25:17

Harvard-Smithsonian Center for Astrophysics The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time. "Astronomers have found runaway stars before, but this is the first time we've found a runaway star...

Scientists Create The First 360-Degree Virtual Map Of The Milky Way
2014-03-21 07:25:44

[ Watch the Video: 360-Degree View of the Milky Way ] Lawrence LeBlond for redOrbit.com - Your Universe Online NASA’s Spitzer Space Telescope has been busy studying stars, asteroids, galaxies and other outer space objects over the past 10 years and a University of Wisconsin team of scientists has now used more than two million images produced by Spitzer to create a virtual 360-degree mosaic of our Milky Way. The team presented the new interactive map Thursday at the TEDActive 2014...

WASHINGTON, March 20, 2014 /PRNewswire-USNewswire/ -- Touring the Milky Way now is as easy as clicking a button with NASA's new zoomable, 360-degree mosaic presented Thursday at the TEDActive 2014 Conference in Vancouver, Canada. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The star-studded panorama of our galaxy is constructed from more than 2 million infrared snapshots taken over the past 10 years by NASA's Spitzer Space Telescope. "If we actually printed this out, we'd...

Collage of galaxies in the Herschel Reference Survey
2014-03-18 19:58:57

ESA The largest census of dust in local galaxies has been completed using data from ESA’s Herschel space observatory, providing a huge legacy to the scientific community. Cosmic dust grains are a minor but fundamental ingredient in the recipe of gas and dust for creating stars and planets. But despite its importance, there is an incomplete picture of the dust properties in galaxies beyond our own Milky Way. Key questions include how the dust varies with the type of galaxy, and how...

Spiral Galaxy M81 is an example of a fat bulgy galaxy
2014-02-28 11:19:26

Brett Smith for redOrbit.com - Your Universe Online A pair of Australian astrophysicists has shown that the shape of a galaxy is determined by how fast it spins, according to a new report in The Astrophysical Journal. Part of “The Evolving Universe” research series at the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO) in Australia, the new study concluded that fatter spiral galaxies are relatively slow spinning, while thinner spiral galaxies are rotating are higher...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
