Cassini finds 'missing link' moonlet evidence in Saturn's rings
Scientists with NASA's Cassini mission have found evidence that a new class of small moonlets resides within Saturn's rings. There may be as many as 10 million of these objects within one of Saturn's rings alone. view more (2006-03-30)
Half-baked asteroids have Earth-like crust
Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. view more (2009-01-08)
The Drifting Star
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. view more (2008-04-16)
NASA Scientists Pioneer Method for Making Giant Lunar Telescopes
Scientists working at NASA's Goddard Space Flight Center in Greenbelt, Md., have concocted an innovative recipe for giant telescope mirrors on the Moon. To make a mirror that dwarfs anything on Earth, just take a little bit of carbon, throw in some epoxy, and add lots of lunar dust. view more (2008-06-05)
Finally, the 'Planet' in Planetary Nebulae?
Astronomers at the University of Rochester, home to one of the world's largest groups of planetary nebulae specialists, have announced that low-mass stars and possibly even super-Jupiter-sized planets may be responsible for creating some of the most breathtaking objects in the sky. view more (2008-03-11)
Meteor impacts: Life's jump starter?
Meteor impacts are generally regarded as monstrous killers and one of the causes of mass extinctions throughout the history of life. view more (2005-08-09)
UK astronomers take control of the time domain
Although there are numerous telescopes - both large and small - examining the night sky at any one time, the heavens are so vast and so densely populated with all manner of exotic objects that it is extremely easy to overlook a significant random event. Fortunately, a new generation of scientific instruments is now enabling UK astronomers to... view more... (2004-02-09)
The Mouse That Roared: Pipsqueak Star Unleashes Monster Flare
On April 25, NASA's Swift satellite picked up the brightest flare ever seen from a normal star other than our Sun. The flare, an explosive release of energy from a star, packed the power of thousands of solar flares. It would have been visible to the naked eye if the star had been easily observable in the night sky at the time. view more (2008-05-20)
Unique Martian formation reproduced, reveals brief bursts of water
Researchers from the United States and the Netherlands report that several formations on Mars indicate incidents of rapid release of water from the planet's interior. view more (2008-02-21)
Eclipsing brown dwarfs provide new key to the star formation process
Pity the brown dwarf. It's too large to be a planet, but too small to be a star. view more (2006-03-16)
IBEX spacecraft detects fast neutral hydrogen coming from the moon
NASA's Interstellar Boundary Explorer (IBEX) spacecraft has made the first observations of very fast hydrogen atoms coming from the moon, following decades of speculation and searching for their existence. view more (2009-06-19)
42-meter giant will probe the universe
The future of European astronomy is poised to enter a new era of discovery with the decision announced today by ESO's governing body to proceed with detailed studies for the European Extremely Large Telescope (E-ELT). view more (2006-12-13)
Meteorite grains divulge Earth's cosmic roots
The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict. view more (2009-06-16)
Binary asteroid in Jupiter's orbit may be icy comets from solar system's infancy
Astronomers at the University of California, Berkeley, working with colleagues in France and at the Keck Telescope in Hawaii, have calculated the density of a known binary asteroid system that shares Jupiter's orbit, and concluded that Patroclus and its companion probably are composed mostly of water ice covered by a patina of dirt. view more (2006-02-02)
Creation of a magnetic field in a turbulent fluid
Understanding the origin and behavior of the magnetic fields of planets and stars is the goal of research being carried out by many teams from all over the world. view more (2007-03-12)
Basque Country University researchers publish two articles in Nature on latest discoveries on Venus
Nature journal has published a series of articles devoted to the new discoveries by the European Space Agency's (ESA) Venus Express space probe made on our neighbouring planet. view more (2007-12-03)
Hot spot on Enceladus causes plumes
Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so intellectually hot, it's smokin'. view more (2007-12-18)
Spread of plant diseases by insects can be described by equations that model interplanetary gravity
Researchers from Penn State University and the University of Virginia show that the spread of diseases by insects can be described by equations similar to those that describe the force of gravity between planetary objects. view more (2006-09-05)
GROUND-BASED TELESCOPES HAVE AN EXTREMELY LARGE FUTURE
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: GROUND-BASED TELESCOPES HAVE AN EXTREMELY LARGE FUTURE view more (2005-03-28)
Unveiling the true face of a gigantic star
An international team of astronomers, led by Keiichi Ohnaka at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, has made the most high resolution images of a dying giant star to date. view more (2009-08-07)
