Hubble Provides Evidence That Galaxies Do Not Confine Starbursts
2013-04-25 08:22:14

WATCH VIDEOS: [Animation of a Starburst Galaxy] | [Probing a Galactic Halo] Lee Rannals for redOrbit.com — Your Universe Online Astronomers writing in The Astrophysical Journal say they've observed how bursts of star formation have a major impact beyond the boundaries of their host galaxy. When galaxies form new stars, they can create frantic episodes of activity known as starbursts. Scientists using the Hubble Space Telescope say these events can affect galactic gas at...

Airborne Observatory Reveals Mystery Of Star Formation
2013-04-17 11:52:24

Brett Smith for redOrbit.com - Your Universe Online Using observations from an airborne observatory, NASA researchers have discovered new details on how massive stars form within a cloud of interstellar gas and dust. An emerging star known as G35 has been observed forming in an orderly process similar to the one undergone by smaller stars like our sun, according to the scientists´ report in the Astrophysical Journal. Lead author Yichen Zhang said the observations of G35 made...

Probes Of Dark Matter On Galaxy Scales 2013
2013-04-03 19:01:07

Lee Rannals for redOrbit.com — Your Universe Online Scientists are coming together this summer to try and collaborate on solving the mystery of dark matter. Probes of Dark Matter on Galaxy Scales 2013, will be held July 14—19 in Monterey, California. Scientists at the conference will be meeting to discuss their techniques for solving the secrets of dark matter in the universe. “The idea is to bring together people working on different probes of dark matter from...

Young Supernova Remnant Discovered By NASA’s Swift Satellite
2013-03-16 10:18:20

redOrbit Staff & Wire Reports — Your Universe Online NASA´s Swift space observatory detected the previously undiscovered remains of a supernova during an extensive X-ray survey of the Milky Way, officials from the US space agency announced on Friday. NASA believes the shattered star remains, which have been named G306.3—0.9 after the coordinates of its sky position, are among the youngest-known supernova remnants in the galaxy. “Astronomers have previously...

Are We There Yet? Astronomers Measure Distance To Neighboring Galaxy
2013-03-06 12:13:52

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have now accurately measured the distance to our neighboring galaxy, the Large Magellanic Cloud (LMC). Scientists have struggled with trying to find an accurate distance to the LMC, which is one of the nearest galaxies to the Milky Way. However, a team of astronomers used observations of a rare class of double star, known as eclipsing binaries, to determine that LMC lies 163,000 light-years...

Scientists Recreate Spiral Arms Of Ancient Milky Way
2013-03-04 19:11:57

Brett Smith for redOrbit.com — Your Universe Online Using observations made possible by the European Space Agency´s INTEGRAL satellite, a pair of French scientists has been able to recreate how the Milky Way´s spiral arms looked millions of years ago. According to their report in the Astrophysical Journal, the two researchers based their recreation on the observations of high mass X-ray binaries (HMXBs), pairs of massive stars that are surrounded with the remnants of...

What Is Dark Matter Podcast

John P. Millis, PhD for redOrbit.com — Your Universe Online Listen to redOrbit's exclusive interview “What Is Dark Matter Podcast” with Dr. Matthew Walker (Or right-click on the above link to download the file to your computer) In the early 1930s, the Swiss astronomer Fritz Zwickey made a startling observation that would eventually become one of the greatest cosmological riddles of the twentieth century and beyond. While attempting to measure the mass of a large...

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...

Crowded Star Clusters Defy Simple View Of Gravity
2013-02-21 09:00:07

April Flowers for redOrbit.com - Your Universe Online On large astronomical scales, gravity remains the dominant force acting on heavenly bodies, from asteroids and exoplanets to solar systems and supermassive black holes. But when it comes to young stars in clustered galaxies, researchers have found that the dynamics of these crowded environments cannot be fully accounted for by simple understanding of gravity. A new study, led by the“¯Kavli Institute for Astronomy and...

Astronomers Capture Rare Glimpse Of Star-Forming Region In Visible Light
2013-01-16 07:00:46

[Watch Videos: 1 - Zooming in on Lupus 3 / 2 - Panning Over Lupus 3] Lawrence LeBlond for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) released a stunning new image of a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged from the stellar nursery. The new image, taken with MPG/ESO 2.2-meter telescope at La Silla Observatory in Chile, is one of the finest and clearest ever taken in visible light of...

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...
