"Future Science: The Frontiers of 21st Century Astronomy" will address grand challenge topics.
University of Notre Dame astronomer Peter Garnavich and a team of collaborators have discovered a distant star that exploded when its center became so hot that matter and anti-matter particle pairs were created.
Less than two months after they inaugurated the worldâ€™s largest telescope, University of Florida astronomers have used one of the worldâ€™s most advanced telescopic instruments to gather images of the heavens.
Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, â€œsupernovaeâ€ for short, certainly works: itâ€™s how dark energy was discovered in the first place.
Two enormous black holes appear to be orbiting one another at the center of a faraway galaxy, formed by the collision of two separate galaxies.
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters.
Researchers using NASA's Spitzer Space Telescope have discovered large amounts of simple organic gases and water vapor in a possible planet-forming region around an infant star, along with evidence that these molecules were created there.
Disks of hot gas that accumulate around a wide variety of astronomical objectsâ€”from degenerate stars in energetic binary systems to supermassive black holes at the hearts of active galaxiesâ€”are likely to be much larger than previously believed.
Astronomers have unmasked hundreds of black holes hiding deep inside dusty galaxies billions of light-years away. The massive, growing black holes represent a large fraction of a long-sought missing population.
A beautiful new image of spiral galaxy IC 342 that takes advantage of the dark night sky at Kitt Peak National Observatory is being released today in Washington, DC.
Cerro Tololo Observatory -- astronomical observatory located on Cerro Tololo peak, Chile, with offices in La Serena, about 40 mi (64 km) to the west. Funded by the U.S. National Science Foundation (NSF), it is operated by the Association of Universities for Research in Astronomy (AURA), which also operates such other major national observatories as the Kitt Peak National Observatory in Arizona. The principal instrument is a 158-in. (4-m) reflecting telescope, the largest in the...
Kitt Peak Observatory -- astronomical observatory located southwest of Tucson, Ariz.; it was founded in 1958 under contract with the National Science Foundation and is administered by the Association of Universities for Research in Astronomy. Its principal instrument is the Mayall 158-in. (4-m) reflector. The observatory's equipment also includes 84-in. (2.1 m), 50-in. (1.3-m), 36-in. (0.9-m), and 16-in. (0.4-m) reflecting telescopes as well as a planned 3.5-m telescope. Used for wide...
