WIYN Telescope Captures Highly Detailed Whirlpool Galaxy Image
2013-07-26 18:40:41

Brett Smith for redOrbit.com - Your Universe Online Astronomers have been observing the Whirlpool Galaxy since the 18th century, but they've never seen it like this. A new One Degree Imager (ODI) camera at the Kitt Peak National Observatory in Arizona has captured stunning new images of the distant spiral galaxy in never-before-seen detail. When used with the WIYN 3.5-meter telescope at the observatory, the camera is able to provide images of the Whirlpool Galaxy and its companion...

New Hubble Image Shows Interacting Galaxies
2013-06-20 18:59:33

Lee Rannals for redorbit.com — Your Universe Online New images taken by the Hubble Space Telescope of a pair of galaxies experiencing a close encounter have been released. The new image features interacting galaxies known as Arp 142. These galaxies have strayed a little too close to each other, causing them to interact and create big changes in both objects. Astronomers say the two galaxies are interacting violently by exchanging matter and causing havoc. Arp 142 was named...

Halo Clouds Spotted Around Colliding Galaxies

April Flowers for redOrbit.com - Your Universe Online A detailed study of an enormous cloud of hot gas that envelops two large, colliding galaxies has been made using NASA´s Chandra X-ray Observatory. This oversized gas reservoir contains as much mass as 10 billion Suns, is 300,000 light years across, and radiates more than 7 million degrees Kelvin. Scientists call this sort of cloud a “halo.” This particular halo is located in the system designated NGC 6240, which...

Galaxy Pair Imaged By Hubble

Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has taken a portrait of two different galaxies forming a peculiar galaxy pair called Arp 116. The image released today shows the dramatic differences in size, structure and color between spiral and elliptical galaxies. Arp 116 is made up of a typical elliptical galaxy known as Messier 60, and a smaller spiral galaxy called NGC 4647. Messier 60 is a typical elliptical galaxy, but together with its...

Watch the Video: Recreating a Slice of the Universe Lee Rannals for redOrbit.com - Your Universe Online Scientists have found a way to accurately follow the birth and evolution of thousands of galaxies over billions of years. For the first time, scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) and their colleagues at the Heidelberg Institute for Theoretical Studies (HITS) have made it possible to build a universe from scratch that brims with galaxies like we...

The Star Factory: Observing Arp 220
2012-02-20 04:07:11

The galaxy Arp 220 is home to several giant star clusters–about 10 million solar masses–that are twice as massive as any comparable star cluster in the Milky Way Galaxy. McMaster University's Christine Wilson is captivated by this turbulent galaxy that provides such a target-rich environment for watching stars form. The reason that star formation is going wild is that the galaxy is in the late stages of a merger between two larger galaxies. "This is a nearby look at a...

  ESO´s Very Large Telescope has taken a striking image of a beautiful yet peculiar pair of galaxies nicknamed The Eyes. The larger of these, NGC 4438, was once a spiral galaxy but has become badly deformed by collisions with other galaxies in the last few hundred million years. This picture is the first to come out of ESO´s Cosmic Gems program, an initiative in which ESO has granted dedicated observing time for outreach purposes. The Eyes are about 50 million light-years...

A study using NASA's Swift satellite and the Chandra X-ray Observatory has found a second supersized black hole at the heart of an unusual nearby galaxy already known to be sporting one. The galaxy, which is known as Markarian 739 or NGC 3758, lies 425 million light-years away toward the constellation Leo. Only about 11,000 light-years separate the two cores, each of which contains a black hole gorging on infalling gas. The study will appear in a forthcoming issue of The Astrophysical Journal...

What happens when galaxies crash together? For years, these cosmic collisions have been blamed for triggering violent outbursts at the hearts of galaxies. Now, a remarkable piece of detective work has given a verdict: galactic mergers do not usually whet the appetite of the black holes that power these active galactic nuclei, meaning other, less dramatic phenomena are responsible. Most galaxies, including our own, have a huge but well-behaved black hole at their heart, while some have messy...

This collage of galaxies from NASA's Wide-Field Infrared Survey Explorer, or WISE, showcases the many "flavors" that galaxies come in, from star-studded spirals to bulging ellipticals to those paired with other companion galaxies. The WISE team put this collage together to celebrate the anniversary of the mission's launch on Dec. 14, 2009.After launch and a one-month checkout period, WISE began mapping the sky in infrared light. By July of this year, the entire sky had been surveyed,...

The M51 Group, located in Canes Venatici, is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). The few other notable members include the companion galaxy to the Whirlpool Galaxy (M51B) and the Sunflower Galaxy (M63).

Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...

Robert's Quartet is four different galaxies in the process of colliding and merging. The galaxies reside in the Phoenix constellation approximately 160 million light-years away. Its members are NGC 87, NGC 88, NGC 89 and NGC 92, discovered by John Herschel in the 1830s. The quartet is one of the best examples of compact groups of galaxies. Since such groups contain four to eight galaxies in a very small area, they provide great laboratories for the study of galactic interactions and their...

Whirlpool Galaxy -- Discovered 1773 by Charles Messier. The famous Whirlpool galaxy M51 was one of Charles Messier's original discoveries: He discovered it on October 13, 1773, when observing a comet, and described it as a "very faint nebula, without stars" which is difficult to see. Its companion, NGC 5195, was discovered in 1781 by his friend, Pierre Mchain, so that it is mentioned in Messier's 1784 catalog: `It is double, each has a bright center, which are separated 4'35". The two...
