The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes. The cluster is located about 10.2 billion light years away, and is observed as it was when the Universe was only about a quarter of its present age. The galaxy cluster, known as JKCS041, beats the previous record holder by about a billion light years. Galaxy clusters are the largest gravitationally bound objects in the Universe. Finding such a...

In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own. "Swift reveals about 20,000 ultraviolet sources in M31, especially hot, young stars and dense star clusters," said Stefan Immler, a research scientist on the Swift team at NASA's...

Astronomers have reported that the neighboring Andromeda Galaxy appears to have cannibalistic tendencies as it has expanded by "digesting" stars from other nearby galaxies. Writing in the journal Nature, an international team of astronomers made the discovery using the Canada-France-Hawaii Telescope and its MegaCam/MegaPrime digital camera to conduct an ongoing survey. Experts have previously considered the concept of a cannibalistic galaxy, but the new study is the first to bring detailed...

Astronomers have reason to believe that they have witnessed signs of the first planet to be spotted outside of our galaxy. The planet is located in the Andromeda galaxy and is estimated to have a mass six times that of Jupiter. The method of viewing this newly discovered planet is through gravitational lensing, where the light from a very distant, bright source is "bent" around a massive object between the source object and the observer. The team that utilized a type of gravitational...

A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest they may have formed relatively recently. This would run counter to the widely-held belief that massive, luminous galaxies (like our own Milky Way Galaxy) began their formation and evolution shortly after the Big Bang, some 13 billion years ago. Further research into the nature of these objects could open new windows into the study of the origin and early evolution of galaxies....

One of our closest galactic neighbors shows its awesome beauty in this new image from NASA's Spitzer Space Telescope. M33, also known as the Triangulum Galaxy, is a member of what's known as our Local Group of galaxies. Along with our own Milky Way, this group travels together in the universe, as they are gravitationally bound. In fact, M33 is one of the few galaxies that is moving toward the Milky Way despite the fact that space itself is expanding, causing most galaxies in the universe to...

Milky Way Bigger Than Once Thought The Milky Way packs a big punch. In fact, scientists discovered that it is larger than Andromeda - not the little sister it was once thought to be. Scientists mapped the Milky Way in a more detailed, three-dimensional way and found that it's bulkier and spinning faster than astronomers once thought. The Milky Way is denser, with 50 percent more mass, and 15 percent larger in breadth. The research was presented Monday at the American Astronomical Society's...

Iowa State University's Martin Pohl is part of a research team that has developed the first complete map of the Milky Way galaxy's spiral arms. The map shows the inner part of the Milky Way has two prominent, symmetric spiral arms, which extend into the outer galaxy where they branch into four spiral arms. "For the first time these arms are mapped over the entire Milky Way," said Pohl, an Iowa State associate professor of physics and astronomy. "The branching of two of the arms may explain...

A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true, and now new simulations show that, at least in galaxies similar to our own Milky Way, stars such as the sun can migrate great distances. What's more, if our sun has moved far from where it was formed more than 4 billion years ago, that could change the entire notion that there are parts of...

NASA's Hubble Space Telescope has found a galaxy that is the equivalent of the painting of Dorian Gray, a portrait in an Oscar Wilde novel that appears mysteriously to age. Like the fictional painting, the galaxy I Zwicky 18 appears to look older the more astronomers study it. What astronomers once thought was a toddler galaxy by galactic standards may now be considered an adult. The galaxy's youthful appearance was identified some 40 years ago through observations at the Palomar Observatory....

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...
