Astronomers at the California Institute of Technology (Caltech), University of Illinois at Urbana-Champaign (UIUC), and University of Hawaii (UH) have discovered 16 close-knit pairs of supermassive black holes in merging galaxies. The discovery, based on observations done at the W. M. Keck Observatory on Hawaii's Mauna Kea, is being presented in Seattle on January 12 at the meeting of the American Astronomical Society, and has been submitted for publication in the Astrophysical Journal. These...

Astronomers have released the largest digital, color image of the universe ever recorded--a mosaic created from millions of 2.8 megapixel images recorded over the past decade. The image, which was unveiled during the 217th annual meeting of the American Astronomical Society (AAS) in Seattle, Washington on Tuesday, was captured and assembled by researchers with the Sloan Digital Sky Survey (SDSS). SDSS-III, as it has been dubbed, is a full color representation of the night sky that has a...

By Robert Sanders, University of California, Berkeley An unusual galaxy with gas jets could explain how starforming galaxies become red and dead University of California, Berkeley, astronomers may have found the missing link between gas-filled, star-forming galaxies and older, gas-depleted galaxies typically characterized as "red and dead." In a poster to be presented this week at the American Astronomical Society meeting in Seattle, UC Berkeley astronomers report that a long-known...

In a study that pushes the limits of observations currently possible from Earth, a team of NASA and European scientists recorded the "fingerprints" of mystery molecules in two distant galaxies, Andromeda and the Triangulum. Astronomers can count on one hand the number of galaxies examined so far for such fingerprints, which are thought to belong to large organic molecules, says the team's leader, Martin Cordiner of the Goddard Center for Astrobiology at NASA's Goddard Space Flight Center in...

NASA researchers will present new findings on a wide range of space science topics during the meeting of the American Astronomical Society. The meeting runs Sunday, Jan. 9, through Thursday, Jan. 13, at the Washington State Convention and Trade Center, located at 800 Convention Place in Seattle.Media briefings during the conference will discuss new results on exoplanet research, dwarf stars, gamma-ray flashes and black holes. New images will be released from missions including the Hubble...

By Daniel Stolte, University of Arizona Simulating possible chemical processes in the atmosphere of Titan, Saturn's largest moon, a UA-led planetary research team found amino acids and nucleotide bases in the mix -- the most important ingredients of life on Earth In an experiment exploring the chemical processes that might be going on in the hazy atmosphere enshrouding Saturn's largest moon, a University of Arizona-led team of scientists discovered a variety of complex organic molecules...

A huge asteroid visited by Europe's Rosetta probe is encased in a thick, dusty layer of debris at least 2,000 ft. deep, created by eons of impacts that have left the shattered surface with a texture similar to the Earth's Moon. The findings are among the first to emerge from the plethora of data collected by Rosetta during its close flyby of Lutetia 282 million miles from Earth, beyond the orbit of Mars. Details of the encounter are being presented at a conference this week of the Division...

A surprising discovery that hydrogen gas clouds found in abundance in and above our Milky Way Galaxy have preferred locations has given astronomers a key clue about the origin of such clouds, which play an important part in galaxy evolution. "We've concluded that these clouds are gas that has been blown away from the Galaxy's plane by supernova explosions and the fierce winds from young stars in areas of intense star formation," said H. Alyson Ford of the University of Michigan, whose Ph.D...

Astronomers studying the Milky Way have discovered a large number of previously-unknown regions where massive stars are being formed. Their discovery provides important new information about the structure of our home Galaxy and promises to yield new clues about the chemical composition of the Galaxy. "We can clearly relate the locations of these star-forming sites to the overall structure of the Galaxy. Further studies will allow us to better understand the process of star formation and to...

The Hubble Space Telescope's dramatic glimpse of the Carina Nebula, a gigantic cloud of dust and gas bustling with star-making activity, is a glorious feast for the eyes. Energetic young stars are sculpting a fantasy landscape of bubbles, valleys, mountains, and pillars. Now this celestial fantasyland has been brought into view for people who cannot explore the image by sight. Max Mutchler, a research and instrument scientist at the Space Telescope Science Institute in Baltimore, and Noreen...

The Astronomical Journal (AJ) is a peer-reviewed scientific journal ran by the American Astronomical Society and published monthly by the Institute of Physics Publishing. It is one of the premier astronomy journals in the world. It was published by the University of Chicago Press until 2008. The society also owns the Astrophysical Journal. The journal was established in 1849 by Benjamin A. Gould. In 1861, publication was ceased due to the American Civil War. It went unpublished until 1885....
