Study finds two supermassive black holes spiraling toward collision
A pair of supermassive black holes in the distant universe are intertwined and spiraling toward a merger that will create a single super-supermassive black hole capable of swallowing billions of stars. view more (2006-04-06)
Astronomers report mysterious giant star clusters
An international team of astronomers reported evidence for the formation of mysterious "super star clusters" Jan. 9 at the annual meeting of the American Astronomical Society in Washington, D.C. view more (2006-01-11)
World's Smallest Radio Fits in the Palm of the Hand . . . of an Ant
Harnessing the electrical and mechanical properties of the carbon nanotube, a team of researchers has crafted a working radio from a single fiber of that material. view more (2007-11-02)
Milky Way's fastest pulsar is on its way out of the galaxy, astronomers find
The Milky Way's fastest observed pulsar is speeding out of the galaxy at more than 670 miles a second, propelled largely by a kick it received at its birth 2.5 million years ago. view more (2006-02-16)
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)
Exploding star within a star - a recurrent nova!
On 12 February 2006, amateur astronomers reported that a faint star in the constellation of Ophiuchus had suddenly become clearly visible in the night sky without the aid of a telescope. view more (2006-04-07)
General relativity survives gruelling pulsar test — Einstein at least 99.95 percent right
An international research team led by Prof. Michael Kramer of the University of Manchester's Jodrell Bank Observatory, UK, has used three years of observations of the "double pulsar", a unique pair of natural stellar clocks which they discovered in 2003, to prove that Einstein's theory of general relativity-the theory of gravity that... view more...

Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust. view more (2005-08-08)
Nuclear explosion on a dead star - astronomers probe aftermath
A team of astronomers from the UK and Germany have found that a nuclear explosion on the surface of a star 5,000 light years from Earth resulted in a blast wave moving at over 1,700 km per second (one thousand miles per second or almost four million miles per hour!). view more (2006-07-20)
How long is a day on Saturn?
Measuring the rotation period of a rocky planet like the Earth is easy, but similar measurements for planets made of gas, such as Saturn, pose problems. view more (2006-05-04)
New map of the Milky Way charts where stars are born
A team of astronomers from Boston University's Institute for Astrophysical Research has produced the clearest map to-date of the giant gas clouds in the Milky Way that serve as the birthplaces of stars. view more (2006-03-24)
Astronomers weigh 'recycled' millisecond pulsar
A team of U.S. and Australian astronomers is announcing today that they have, for the first time, precisely measured the mass of a millisecond pulsar - a tiny, dead star spinning hundreds of times every second. view more (2006-01-13)
MIT: Mini satellites rocketing to space station
A Russian rocket launched Monday, April 24, is carrying the first of three small, spherical satellites developed at MIT to the International Space Station - a major step toward building space-based robotic telescopes and other systems. view more (2006-04-27)
Black Holes Lead Galaxy Growth, New Research Shows
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores. view more (2009-01-07)
Magnetically guided catheter zaps atrial fibrillation
A remotely-controlled catheter device guided by magnetic fields provides a safe and practical method for delivering radio frequency ablation treatment in the hearts of patients with atrial fibrillation. view more (2006-03-31)
UI's Gurnett finds 'lumpy' ionosphere, glimpses of the subsurface of Mars
University of Iowa Space Physicist Don Gurnett and his UI colleagues report that a scientific instrument aboard the European Space Agency's (ESA) Mars Express spacecraft is working perfectly and that its data have so far revealed that Mars' ionosphere - part of the upper atmosphere - is very lumpy and complex, and that the instrument can... view more...

The cosmos is green: Researchers catch nature in the act of 'recycling' a star
For the first time, researchers have observed a singular cosmic act of rebirth: the transformation of an ordinary, slow-rotating pulsar into a superfast millisecond pulsar with an almost infinitely extended lifespan. view more (2009-05-22)
Astronomers shed surprising light on our galaxy's black hole
In the most comprehensive study of Sagittarius A (Sgr A), the enigmatic supermassive black hole in the center of the Milky Way Galaxy, astronomers - using nine ground and space-based telescopes including the Hubble Space Telescope and the XMM-Newton X-ray Observatory - have discovered that Sgr A* produces rapid flares close to the... view more...

NASA'S Chandra finds black holes stirring up galaxies
Black holes are creating havoc in unsuspected places, according to a new study of images of elliptical galaxies made by NASA's Chandra X-ray Observatory. view more (2006-01-11)
Part-time pulsar yields new insight into inner workings of cosmic clocks
Astronomers using the 76-m Lovell radio telescope at the University of Manchester's Jodrell Bank Observatory have discovered a very strange pulsar that helps explain how pulsars act as 'cosmic clocks' and confirms theories put forward 37 years ago to explain the way in which pulsars emit their regular beams of radio waves-considered to be one of... view more...
