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

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...

Milky Way Surrounded By Halo
2012-09-24 19:28:01

Lee Rannals for redOrbit.com — Your Universe Online The Milky Way Galaxy is known for its spirals, as well as Earth's home in the cosmos, but now it will also be known as a galaxy that features a halo. Astronomers using NASA's Chandra X-ray Observatory found evidence that the Milky Way Galaxy is embedded in a halo of hot gas that extends for hundreds of thousands of light years. Scientists estimated that the mass of the halo found is comparable to the mass of all the stars in...

Lee Rannals for redOrbit.com According to recent studies with the National Science Foundation's Green Bank Telescope (GBT), a couple celestial neighbor galaxies may have had a close encounter with each other billions of years ago. Astronomers confirmed a disputed 2004 discovery of hydrogen gas streaming between the giant Andromeda Galaxy and the Triangulum Galaxy with their new study. "The properties of this gas indicate that these two galaxies may have passed close together in the...

Milky Way Destined For Head-On Collision
2012-06-05 03:18:55

[ Watch the Video ] NASA astronomers announced on May 31 that they can now predict with certainty the next major cosmic event to affect our galaxy, sun, and solar system: the titanic collision of our Milky Way galaxy with the neighboring Andromeda galaxy. The Milky Way is destined to get a major makeover during the encounter, which is predicted to happen four billion years from now. It is likely the sun will be flung into a new region of our galaxy, but our Earth and solar system are in...

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...
