IU astronomer's discovery poses challenge to galaxy formation theories
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. view more (2009-04-13)
Hubble yields direct proof of stellar sorting in a globular cluster
A seven year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass, governed by a gravitational billiard ball game between stars. view more (2006-10-25)
Closest Look Ever at the Edge of a Black Hole
Astronomers have taken the closest look ever at the giant black hole in the center of the Milky Way. By combining telescopes in Hawaii, Arizona, and California, they detected structure at a tiny angular scale of 37 micro-arcseconds - the equivalent of a baseball seen on the surface of the moon, 240,000 miles distant. view more (2008-09-04)
Good cheese on a go slow
A new, more sensitive, way of deciding when cheese curd is ready to be cut from the whey is published today in the Institute of Physics journal, Measurement Science and Technology. Researchers from the University Ibn Zohr in Morocco and Le Havre in France have demonstrated a new technique that could make significant savings by reducing waste and... view more... (2001-11-06)
Resolving a galactic mystery
An extremely deep Chandra X-ray Observatory image of a region near the center of our Galaxy has resolved a long-standing mystery about an X-ray glow along the plane of the Galaxy. view more (2009-04-30)
The colourful demise of a Sun-like star
A brand new image taken with Hubble's Wide Field Planetary Camera 2 shows the planetary nebula NGC 2440 - the chaotic structure of the demise of a star. view more (2007-02-15)
Largest ever survey of very distant galaxy clusters completed
An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. view more (2009-07-01)
A more complete study of the Solar System
The Basque company SENER has been contracted by the European Space Agency (ESA) to prepare a technologies programme for the GAIA astronomy mission. The specifications of this satellite include an 11-metre diameter parasol which unfolds after being put into orbit, giving thermal stability in a passive way to the telescope. SENER is developing this... view more... (2004-02-05)
GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky
The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays. view more (2008-08-27)
Cassiopeia A - The colorful aftermath of a violent stellar death
A new image taken with the NASA/ESA Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way. view more (2006-08-30)
Astronomers discover stars in early galaxies had a need for speed
A team of astronomers has measured the motions of stars in a very distant galaxy for the first time and discovered they are whizzing around at astonishingly high speeds-about one million miles per hour, or twice the speed at which the Sun circles our own Milky Way galaxy. view more (2009-08-07)
Cornell-led team detects dust around a primitive star, shedding new light on universe's origins
A Cornell-led team of astronomers has observed dust forming around a dying star in a nearby galaxy, giving a glimpse into the early universe and enlivening a debate about the origins of all cosmic dust. view more (2009-01-16)
Cosmic battle creates Milky-Way sized tunnel
A team of astronomers is announcing today that they have discovered a giant Milky Way-sized tunnel filled with high energy particles in a distant galaxy cluster. view more (2006-01-12)
Particles as tracers for the most massive explosions in the Milky Way
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter". view more (2009-08-11)
VLT Observations Address the Age of the Universe
The stream of important scientific results from ESOs Very Large Telescope (VLT) at Paranal (Chile) is increasing. Astronomers have had access to the first of the four 8.2-m telescopes since April 1999 and research articles based on observations with this new powerful facility are beginning to appear in larger numbers. The work reported here is one... view more... (1999-12-17)
Discovery of Giant X-ray Loop Hints at Cosmic Particle Accelerator
Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. view more (2005-04-01)
Ultraviolet astronomy in danger
World astronomers are becoming very concerned about their ability to carry out observations in ultraviolet light following recent announcements about the future of the Hubble Space Telescope. Hubble is most famous for the clear images it gives of distant objects from its vantage point above the Earth's atmosphere. It is less well known that its... view more... (2004-03-23)
Supernova remnant menagerie
The supernova remnant N 63A is a member of N 63, a star-forming region in the Large Magellanic Cloud (LMC). Visible from the southern hemisphere, the LMC is an irregular galaxy lying 160,000 light-years from our own Milky Way galaxy. view more (2005-06-07)
