Telescope to probe early universe,more
A novel telescope that will aid the understanding of the early universe is moving closer to full-scale construction thanks to a $4.9 million award from the National Science Foundation to a U.S. consortium led by MIT.
Giant gas clouds illuminate universe's largest structure
A team of astronomers using the Subaru and Keck telescopes on Mauna Kea has discovered giant, three-dimensional filaments of galaxies extending across 200 million light-years of space.
Giant gas clouds illuminate universe's largest structure

New picture of quasar emerges
In the distant, young universe, quasars shine with a brilliance unmatched by anything in the local cosmos. Although they appear starlike in optical telescopes, quasars are actually the bright centers of galaxies located billions of light-years from Earth.
A sub-stellar Jonah
Using ESO's Very Large Telescope, astronomers have discovered a rather unusual system, in which two planet-size stars, of different colours, orbit each other. One is a rather hot white dwarf, weighing a little bit less than half as much as the Sun.
The "Planemo" twins
The cast of exoplanets has an extraordinary new member.Astronomers have discovered an approximately seven-Jupiter-mass companion to an object that is itself only twice as hefty.
Mars' dust storm may produce peroxide snow
The planet-wide dust storms that periodically cloak Mars in a mantle of red may be generating a snow of corrosive chemicals, including hydrogen peroxide, that would be toxic to life.
Researchers use NRAO telescope to study formation of chemical precursors of life
In just two years of work, an international research team has discovered eight new complex, biologically-significant molecules in interstellar space using the National Science Foundation's Robert C. Byrd Green Bank Telescope.
Astronomers crunch numbers, universe gets bigger
That intergalactic road trip to Triangulum is going to take a little longer than you had planned.the Triangulum Galaxy, otherwise known as M33, is actually about 15 percent farther away from our galaxy than previously measured.
The iau draft definition of 'planet' and 'plutons'
The world's astronomers, under the auspices of the International Astronomical Union (IAU), have concluded two years of work defining the difference between "planets" and the smaller "solar system bodies" such as comets and asteroids. If the definition is approved by the astronomers gathered 14-25 August 2006 at the IAU General Assembly in Prague, our Solar System will include 12 planets, with more to come: eight classical planets that dominate the system, three planets in a new and growing category of "plutons" – Pluto-like objects – and Ceres. Pluto remains a planet and is the prototype for the new category of "plutons."

Team uncovers faintest stars ever seen in ancient star cluster
An international team of astronomers led by UBC professor Harvey Richer has uncovered the faintest stars ever seen in any globular star cluster, bringing scientists closer to revealing the formation time of one of the earliest generations of stars in the Universe.
Mystery of quintuplet stars in milky way solved
For the first time, scientists have identified the cluster of Quintuplet stars in the Milky Way's galactic center, next to the super massive black hole, as massive binary stars nearing the end of their life cycle, solving a mystery that had dogged astronomers for more than 15 years.
Stars too old to be trusted
Analysing a set of stars in a globular cluster with ESO's Very Large Telescope, astronomers may have found the solution to a critical cosmological and stellar riddle. Until now, an embarrassing question was why the abundance of lithium produced in the Big Bang is a factor 2 to 3 times higher than the value measured in the atmospheres of old stars. The answer, the researchers say, lies in the fact that the abundances of elements measured in a star's atmosphere decrease with time.
Gemini captures close encounter of jupiter's red spots
A high-resolution image just released by the Gemini Observatory shows two giant red spots brushing past one another in Jupiter's southern hemisphere.
Scientists find possible origin of mysterious red and blue lights in the milky way galaxy
NASA's Goddard Space Flight Center, Greenbelt, Md., in collaboration with university scientists, have solved yet another mystery.For years, scientists have observed unstructured silicate particles in space
Astronomers use supercomputers to study atoms linked to black holes
Super-hot atoms in space hold the key to an astronomical mystery, and an Ohio State University astronomer is leading an effort to study those atoms here on Earth.
Parkes finds unexpected 'heartbeats' in star
A US-Australian research team found that a "magnetar" – a kind of star with the strongest magnetic fields known in the Universe – is giving off extraordinary radio pulses, which links this rare type of star with the much more common "radio pulsars".
Far away galaxy under the microscope
An international group of astronomers have discovered large disc galaxies akin to our Milky Way that must have formed on a rapid time scale, only 3 billion years after the Big Bang. In one of these systems, the combination of adaptive optics techniques with the new SINFONI spectrograph on ESO's Very Large Telescope (VLT) resulted in a record-breaking resolution of a mere 0.15 arcsecond, giving an unprecedented detailed view of the anatomy of such a distant proto-disc galaxy.
Earth-like planets may be more common than once thought
More than one-third of the giant planet systems recently detected outside Earth's solar system may harbor Earth-like planets, many covered in deep oceans with potential for life, according to a new study led by the University of Colorado at Boulder and Pennsylvania State University.
Researcher finds massive black hole 12.7 billion light-years away
Astronomer Tomotsugu Goto from the Japan Aerospace Exploration Agency (JAXA) has used the Subaru telescope to identify a distant quasar powered by a massive black hole. The quasar is almost 12.7 billion light-years away from Earth in the direction of the constellation Cancer the Crab. It is the most distant one ever found by a Japanese researcher and the eleventh most distant quasar currently known.
