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...

Andromeda Surrounded By Dwarf Galaxies
2013-01-04 04:57:16

April Flowers for redOrbit.com - Your Universe Online Astronomers have discovered a group of dwarf galaxies moving in unison near the Andromeda Galaxy around the host known as Messier 31 using the MegaCam on the Canada-France-Hawaii and W. M. Keck Observatory telescopes on the summit of Mauna Kea, Hawaii. Analogous to the planets of our own Solar System, the structure of these small galaxies — nearly half that orbit Andromeda - lies in a plane. What is truly surprising to the...

NASA's Swift Team Collects More Than 100 Snapshots For Image Gallery Gift
2012-12-31 10:31:00

NASA Of the three telescopes carried by NASA's Swift satellite, only one captures cosmic light at energies similar to those seen by the human eye. Although small by the standards of ground-based observatories, Swift's Ultraviolet/Optical Telescope (UVOT) plays a critical role in rapidly pinpointing the locations of gamma-ray bursts (GRBs), the brightest explosions in the cosmos. But as the proxy to the human eye aboard Swift, the UVOT takes some amazing pictures. The Swift team is...

Spotting Distant Galaxy Clusters With WISE
2012-12-07 05:33:49

April Flowers for redOrbit.com - Your Universe Online As grand and colorful as it is, our solar system is a fleck in the grander cosmos. Our Milky Way galaxy has hundreds of billions of solar systems, yet it is only just a drop in the sea of galaxies. Galaxy clusters, the rarest and largest of galaxy groupings, can be the hardest to find, which is where NASA's Wide-field Infrared Survey Explorer (WISE) becomes helpful. So far, the mission's all-sky infrared maps have revealed one...

Andromeda Project Wants Your Help Searching For Star Clusters
2012-12-05 13:08:22

Lee Rannals for redOrbit.com - Your Universe Online A new project, named The Andromeda Project, is asking the public's help to search through Hubble Space Telescope images to identify star clusters and increase our understanding of how galaxies evolve. The new project is a collaboration between scientists at the University of Washington, the University of Utah and other partners, aiming to study thousands of high-resolution Hubble images. “It´s an amazing opportunity to...

Most Distant Galaxy Record Broken
2012-11-15 22:10:07

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have found the most distant galaxy ever seen in the universe by using NASA's Hubble and Spitzer space telescopes. The newly discovered galaxy, named MACS0647-JD, is only a tiny fraction of the size of our Milky Way galaxy, and is observed at 420 million years after the big bang. MACS0647-JD offers a glimpse into what the universe was like when it was just three percent of its present age of 13.7 billion years old....

Monster Galaxy Found
2012-10-25 22:05:33

Lee Rannals for redOrbit.com — Your Universe Online A team of astronomers has grabbed an image of a huge elliptical galaxy with a core that is bigger than any seen before. The team used the Hubble Space Telescope to collect the image of the galaxy, which is about ten times the diameter of the Milky Way galaxy. The galaxy is a member of a class of galaxies with an unusually diffuse core filled without a concentrated peak of light around a central black hole. Viewing the core...

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...
