Solar System's Young Twin Has Two Asteroid Belts
Astronomers have discovered that the nearby star Epsilon Eridani has two rocky asteroid belts and an outer icy ring, making it a triple-ring system. The inner asteroid belt is a virtual twin of the belt in our solar system, while the outer asteroid belt holds 20 times more material. Moreover, the presence of these three rings of material implies... view more... (2008-10-28)
No rest on the way to the most mysterious of Saturn`s moons
After an adventurous 7-year long tour among the planets, the Cassini-Huygens spacecraft will arrive at Saturn in July 2004. Once there, Cassini will parachute the Huygens probe to Saturn`s biggest satellite, Titan. Titan is thought to have an atmosphere similar to the primitive Earth. However, both the probe and the Cassini-Huygens team are not in... view more... (2002-08-28)
Trigger-happy star formation
A new study from two of NASA's Great Observatories provides fresh insight into how some stars are born, along with a beautiful new image of a stellar nursery in our Galaxy. view more (2009-08-13)

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)
28 new planets, 7 new brown dwarfs reported by California, Carnegie team
The world's largest and most prolific team of planet hunters announced today (Monday, May 28) the discovery of 28 new planets outside our solar system, increasing to 236 the total number of known exoplanets. view more (2007-05-30)
Study highlights role of hit-and-run collisions in planet formation
Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and meteorites. view more (2006-01-12)
Planet or failed star? One of smallest stellar companions seen by Hubble
Astronomers using the NASA/ESA Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet. view more (2006-09-11)
Record-setting laser may aid searches for Earthlike planets
Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. view more (2008-05-08)
How the moon got its stripes
A new study has revealed the origins of tiger stripes and a subsurface ocean on Enceladus- one of Saturn's many moons. These geological features are believed to be the result of the moon's unusual chemical composition and not a hot core, shedding light on the evolution of planets and guiding future space exploration. view more (2009-07-15)
For the paper trail of life on Mars or other planets, find cellulose
Looking for evidence of life on Mars or other planets? Finding cellulose microfibers would be the next best thing to a close encounter, according to new research from the University of North Carolina at Chapel Hill. view more (2008-03-31)
Three new 'Trojan' asteroids found sharing Neptune's orbit
Three new objects locked into roughly the same orbit as Neptune—called "Trojan" asteroids—have been found by researchers from the Carnegie Institution's Department of Terrestrial Magnetism (DTM) and the Gemini Observatory in Hilo, Hawaii. view more (2006-06-16)
New rocky planet found in constellation Leo
Spanish and UCL (University College London) scientists have discovered a possible terrestrial-type planet orbiting a star in the constellation of Leo. The new planet, which lies at a distance of 30 light years from the Earth, has a mass five times that of our planet but is the smallest found to date. One full day on the new planet would be... view more... (2008-04-10)
A tiny frozen microbe may hold clues to extraterrestrial life
A novel bacterium that has been trapped more than three kilometres under glacial ice in Greenland for over 120 000 years, may hold clues as to what life forms might exist on other planets. view more (2009-06-15)
Livermore researchers shed new light on the physical properties of carbon
A team based in Livermore has shed some new light on the phase diagram of carbon at high pressure and temperature. view more (2006-01-25)
Stellar still births
The systematics of celestial bodies apparently needs to be revised. Researchers at the Argelander Institute of Astronomy of the University of Bonn have discovered that brown dwarfs need to be treated as a separate class in addition to stars and planets. view more (2008-08-25)
Physicists uncover new solution for cosmic collisions
It turns out that our math teachers were right: being able to solve problems without a calculator does come in handy in the "real" world. view more (2008-01-11)
NASA Supercomputer Shows How Dust Rings Point to Exo-Earths
Supercomputer simulations of dusty disks around sunlike stars show that planets nearly as small as Mars can create patterns that future telescopes may be able to detect. The research points to a new avenue in the search for habitable planets. view more (2008-10-13)
Caltech scientists predict greater longevity for planets with life
Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear. view more (2009-06-15)
Arctic expedition will investigate alien-like glacier
A scientific expedition to a remote glacier field in Canada's High Arctic may help researchers unlock the secrets about the beginning of life and provide insights for future exploration of our solar system. view more (2006-06-14)
