Monitoring Yellowstone earthquake swarms
The Seismological Society of America (SSA) is an international scientific society devoted to the advancement of seismology and its applications in understanding and mitigating earthquake hazards and in imaging the structure of the earth. view more (2009-04-10)
The high mountain station in the Pamirs was destroyed by bandits
More than thirty years ago V.K.Nosdruhin, the expedition chief of the Central Asia Hydrometeorological Institute, proposed to organize a stationary base to observe glaciers. The base was placed on the Abramov glacier in the Pamirs. This place, in the Alaisky ridge, is a most beautiful one. The observatory with three subdivisions was constructed by... view more...

Astronomers detect matter torn apart by black hole
Astronomers have used two different telescopes simultaneously to study the violent flares from the supermassive black hole in the centre of the Milky Way. They have detected outbursts from this region, known as Sagittarius A*, which reveal material being stretched out as it orbits in the intense gravity close to the central black hole. view more (2008-11-19)
Brightest stellar explosion heralds new type of long-distance astronomy
A flash of light that blinded even small telescopes six months ago was the brightest astronomical explosion ever observed - visible to the naked eye despite originating halfway across the universe. view more (2008-09-11)
Integral expands our view of the gamma-ray sky
Integral's latest survey of the gamma-ray universe continues to change the way astronomers think of the high-energy cosmos. With over seventy percent of the sky now observed by Integral, astronomers have been able to construct the largest catalogue yet of individual gamma-ray-emitting celestial objects. view more (2007-02-21)
Is the Sagittarius dwarf galaxy a debris of the Large Magellanic Cloud?
The Sagittarius dwarf galaxy is our nearest neighbor. Yet it has been discovered only recently, in 1994, being hidden by the stars and dust in our own Galaxy, the Milky Way. It is however possible today to better know this companion galaxy, thanks to variable stars, the RR Lyrae, in which Sgr-dw is particularly rich. In a recent paper, Patrick... view more...

'Cosmic telescopes' may have found infant galaxies
Using massive clusters of galaxies as "cosmic telescopes," a research team led by a Johns Hopkins University astronomer has found what may be infant galaxies born in the first billion years after the beginning of the universe. view more (2006-06-06)
Hubble shows 'baby' galaxy is not so young after all
The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much... view more... (2007-10-17)
1843 stellar eruption may be new type of star explosion
Eta Carinae, the galaxy's biggest, brightest and perhaps most studied star after the sun, has been keeping a secret: Its giant outbursts appear to be driven by an entirely new type of stellar explosion that is fainter than a typical supernova and does not destroy the star. view more (2008-09-11)
Space X-ray telescope arrives for tests at RAL
An X-ray telescope weighing half a tonne, due for launch on a Russian spacecraft in 1998, arrived at CLRC's Rutherford Appleton Laboratory today for thermal tests. With conditions in space so different from those on Earth (space is an icy-cold vacuum), it is vital to test any instrument before launch to make sure that it can work in a vacuum at... view more...

Precise Radio-Telescope Measurements Advance Frontier Gravitational Physics
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics. view more (2009-09-02)
Pulsar find boosts hope for gravity-wave hunters
Neutron star pairs may merge and give off a burst of gravity waves about six times more often than previously thought, scientists report in today's issue of the journal Nature [4 December]. If so, the current generation of gravity-wave detectors might be able to register such an event every year or two, rather than about once a decade - the most... view more... (2003-12-02)
Aircraft and radar antenna help test instruments for space mission
The CLRC Chilbolton Observatory in Hampshire has been host to scientists from the UK, France, Germany and the Netherlands who have been testing radar and lidar instruments on board three separate aircraft, together with many ground-based instruments, to test the feasibility for a future European space mission which will gather data from space on... view more...

Stars Form Surprisingly Close to Milky Way's Black Hole
NASA's Chandra X-ray Observatory revealed a new generation of stars spawned by a super-massive black hole at the center of the Milky Way galaxy. view more (2005-10-14)
Galaxy collisions dominate the local universe
More than half of the largest galaxies in the nearby universe have collided and merged with another galaxy in the past two billion years, according to a Yale astronomer in a study using hundreds of images from two of the deepest sky surveys ever conducted. view more (2005-12-06)
Astronomers discover record 5th planet around nearby star 55 Cancri
A team of American astronomers announced today (Tuesday, Nov. 6) the discovery of a record-breaking fifth planet around the nearby star 55 Cancri, making it the only star aside from the sun known to have five planets. view more (2007-11-07)
XMM-Newton reveals X-rays from gas streams around young stars
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays. view more (2007-06-01)
Rogue Black Holes May Roam the Milky Way
It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may... view more...

Spitzer nets thousands of galaxies in a giant cluster
In just a short amount of time, NASA's Spitzer Space Telescope has bagged more than a thousand previously unknown dwarf galaxies in a giant cluster of galaxies. view more (2007-05-29)
Supernova Explosions Stay In Shape
At a very early age, children learn how to classify objects according to their shape. Now, new research suggests studying the shape of the aftermath of supernovas may allow astronomers to do the same. view more (2009-12-18)
