Plan to identify watery Earth-like planets develops
Astronomers are looking to identify Earth-like watery worlds circling distant stars from a glint of light seen through an optical space telescope and a mathematical method developed by researchers at Penn State and the University of Hawaii. view more (2008-04-24)
Universe's oldest objects emerge from the background
The deepest reaches of space are permeated by a cloak of infrared radiation, an uneven energy swath generated by long-dead objects from the early universe. view more (2006-12-20)
Cosmic dust in farthest quasar clue to early star formation
UK astronomers using the 15-m James Clerk Maxwell Telescope in Hawaii have discovered enormous quantities of cosmic dust in the most distant quasar yet observed. The quasar, called SDSS J1148+5251 is at a redshift (z) of 6.43, and is found in the direction of the constellation of Ursa Major. It is... view more (2003-04-02)
Light echoes whisper the distance to a star
Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance ladder. view more (2008-02-11)
Hubble and Spitzer Space Telescopes find 'Lego-block' galaxies in early universe
The conventional model for galaxy evolution predicts that small galaxies in the early Universe evolved into the massive galaxies of today by coalescing. Nine Lego-like "building block" galaxies initially detected by Hubble likely contributed to the construction of the Universe as we know... view more (2007-09-07)
Light Gives Asteroids Spin
Astronomers have observed an asteroid change the rate at which it spins for the first time, and shown that this is due to a theoretical effect predicted but never before seen view more (2007-03-12)
Chandra examines Jupiter during new horizons approach
On February 28, 2007, NASA's New Horizons spacecraft made its closest approach to Jupiter on its ultimate journey to Pluto. This flyby gave scientists a unique opportunity to study Jupiter using the package of instruments available on New Horizons, while coordinating observations from both space-... view more (2007-03-02)
New Instruments To Picture The Early Universe
The latest instrument of the UK's Tenerife Cosmic Microwave Background Experiment, has been officially inaugurated at the mountain top Teide Observatory of the Instituto de Astrofisica de Canarias, IAC, on Tenerife. The ceremony coincided with the announcement by the PPARC of major support for a... view more (1996-07-03)
Sacred constant might be changing
Physical constants are one of the cornerstones of physics - sacred numbers which we know to be fixed - but what if some of these constants are changing? Speaking at the Institute of Physics conference Physics 2005, Dr Michael Murphy of Cambridge University will discuss the "fine structure... view more (2005-04-05)
Search for Sirius companions
Many direct or indirect observations have suggested the existence of a second companion (in addition of the white dwarf Sirius-B) around the brilliant star Sirius-A. The presence of a second faint star could in particular explain a change of color of Sirius, as suggested by historical texts. A team... view more (2000-11-24)
Cranfield University reaches for the stars
Looking into the night sky you may see a few stars and the moon. Astronomers, however, are looking for more than this - they are looking for Earth-like planets, which, with a little help from Cranfield University, they may be able to find. As part of a four-year collaborative project, Cranfield... view more (2004-02-13)
Massive star cluster found in Milky Way
A massive cluster of red supergiants-super-sized stars on the verge of exploding-was recently discovered in the Milky Way by a group of stronomers using infrared technology to penetrate the thick dust that cloaks much of the galaxy. view more (2006-01-10)
Sandia experimental package of piezoelectric films to be part of NASA space station experiment
For the past three years a Sandia research team headed by Mat Celina has been investigating the performance of various piezoelectric polymer films that might one day serve as ultra-light mirrors in space telescopes. view more (2006-08-10)
First Image and Spectrum of a Dark Matter Object
HST and VLT Identify MACHO as a Small and Cool Star An international team of astronomers has observed a Dark Matter object directly for the first time. Images and spectra of a MACHO microlens - a nearby dwarf star that gravitationally focuses light from a star in another galaxy - were taken by the... view more (2001-12-05)
NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. view more (2006-08-22)
Dark matter mystery deepens in cosmic 'train wreck'
Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters. view more (2007-08-17)
MIT to lead development of new telescopes on moon
NASA has selected a proposal by an MIT-led team to develop plans for an array of radio telescopes on the far side of the moon that would probe the earliest formation of the basic structures of the universe. view more (2008-02-20)
CU-Boulder supercomputer simulation of universe may help in search for missing matter
Much of the gaseous mass of the universe is bound up in a tangled web of cosmic filaments that stretch for hundreds of millions of light-years, according to a new supercomputer study by a team led by the University of Colorado at Boulder. view more (2007-12-07)
Einstein's dark energy accelerates the universe
The enigmatic "dark energy" that drives the acceleration of the Universe behaves just like Einstein's famed cosmological constant. view more (2005-11-28)
APL Astronomer Spies Conditions 'Just Right' for Building an Earth
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope. view more (2007-10-04)
Aventis Prizes For Science Books - General Prize Shortlist Announced
Aliens, risk, human nature, networks, asymmetry and dark energy provide the inspiration for the books on the shortlist for the £10,000 General Prize of the Aventis Prizes for Science Books 2003. The shortlist for the General Prize, selected from 94 entries submitted this year, is: Small World... view more (2003-05-28)
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... view more (1999-12-17)
Cannibalistic Stars hold clue to Big Bang
A team of UK astronomers announced this month the discovery of cannibalistic stars that explain one of the mysteries surrounding the Big Bang. The stars are almost as old as the Universe and they reveal what space was like in the very beginning. The team from the Open University found that a group... view more (2002-05-10)
Four Eyes Are Better
VLT Interferometer Passes Another Technical Hurdle During the nights of September 15/16 and 16/17, 2002, preliminary tests were successfully carried out during which the light beams from all four VLT 8.2-m Unit Telescopes (UTs) at the ESO Paranal bservatory were successively combined, two by two,... view more (2002-09-26)
