Ideas on gas-giant planet formation take shape
Rocky planets such as Earth and Mars are born when small particles smash together to form larger, planet-sized clusters in a planet-forming disk, but researchers are less sure about how gas-giant planets such as Jupiter and Saturn form.   view more (2006-03-23)

A Planet in Progress?
Scientists are one step closer to understanding how new planets form, thanks to research funded by the National Science Foundation (NSF) and carried out by a team of astrophysicists at the American Museum of Natural History.   view more (2008-03-27)

Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature.   view more (2006-05-11)

First extrasolar planets, now extrasolar moons
ESA is now planning a mission that can detect moons around planets outside our Solar System, those orbiting other stars! Everyone knows our Moon: lovers stare at it, wolves howl at it, and ESA recently sent SMART-1 to study it. But there are over a hundred other moons in our Solar System, each a... view more (2003-10-09)

Earth's Core is a Recycling Product
The planets of the solar system, including the Earth, formed about four and a half billion years ago from a swirling disk of gas and dust that was left over from the newly formed Sun. However, we do not understand, why the Earth ended up being different from other Earth-like or «terrestrial»... view more (2004-02-04)

Even 'failed stars' form planets
An international team of astronomers shows that even brown dwarfs start to form planets.   view more (2005-10-26)

Rapid-born planets present 'baby picture' of our early solar system
Using NASA's Spitzer Space Telescope, a team of astronomers led by the University of Rochester has detected gaps ringing the dusty disks around two very young stars, which suggests that gas-giant planets have formed there.   view more (2005-09-12)

Mars Express has the sophisticated science to find the water ice on Mars
"The presence of such a large amount of water ice under Mars`s surface is very surprising. Especially so close to the surface!" says Gerhard Schwehm, Head of the Planetary Missions Division at ESA. The team working on ESA`s Mars Express, the next mission to the Red Planet, is thrilled by NASA`s... view more (2002-05-30)

Universally Speaking, Earthlings Share a Nice Neighborhood
We don't have spacecraft to take us outside our solar system--not yet, at least. Still, astronomers thought they had a pretty good understanding of how our solar system formed and in turn, how others formed.   view more (2008-08-11)

MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate.   view more (2007-12-26)

Sign of 'Embryonic Planets' Forming in Nearby Stellar Systems
Astronomers at the University of Rochester are pointing to three nearby stars they say may hold "embryonic planets"-a missing link in planet-formation theories.   view more (2007-10-02)

Icy Jupiter Moon Throws a Curve Ball at Formation Theories
Scientists studying data from NASA's Galileo spacecraft have found that Jupiter's moon Amalthea is a pile of icy rubble less dense than water. Scientists expected moons closer to the planet to be rocky and not icy. The finding shakes up long-held theories of how moons form around giant planets.   view more (2005-06-01)

Models show one nearby star system could host Earth-like planet
The steady discovery of giant planets orbiting stars other than our sun has heightened speculation that there could be Earth-type worlds in nearby planetary systems capable of sustaining life.   view more (2006-07-25)

Largest transiting extrasolar planet found around a distant star
An international team of astronomers with the Trans-atlantic Exoplanet Survey announce today the discovery of TrES-4, a new extrasolar planet in the constellation of Hercules.   view more (2007-08-07)

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... view more (2008-04-10)

Floating pile of rubble a pristine record of solar system's history
A small, near-Earth asteroid named Itokawa is just a pile of floating rubble, probably created from the breakup of an ancient planet, according to a University of Michigan researcher was part of the Japanese space mission Hayabusa.   view more (2006-06-02)

Plan to identify watery Earth-like planets develops
Astronomers are looking to identify Earth-like watery worlds circling distant stars from a glint of light seen through an optical space telescope and a mathematical method developed by researchers at Penn State and the University of Hawaii.   view more (2008-04-24)

Kiwi astronomers help find icy 'Super Earth' - Life in space discovery a step closer
By designing a variant of an astronomical technique proposed by Einstein, researchers from The University of Auckland and Massey University, together with astronomers from Auckland's Stardome Observatory, have found evidence for a new icy "Super Earth".   view more (2006-03-15)

Scientists Discover New Planet Orbiting Dangerously Close to Giant Star
A team of astronomers from Penn State and Nicolaus Copernicus University in Poland has discovered a new planet that is closely orbiting a red-giant star, HD 102272, which is much older than our own Sun.   view more (2008-11-19)

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)

NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth.   view more (2007-02-23)

COROT finds exoplanet orbiting Sun-like star
A team of European scientists working with COROT have discovered an exoplanet orbiting a star slightly more massive than the Sun. After just 555 days in orbit, the mission has now observed more than 50 000 stars and is adding significantly to our knowledge of the fundamental workings of stars.   view more (2008-07-28)

APL Astronomer Spies Conditions 'Just Right' for Building an Earth
An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope.   view more (2007-10-04)

Mars Express discovers aurorae on Mars
ESA's Mars Express spacecraft has for the first time ever detected an aurora on Mars. This aurora is of a type never previously observed in the Solar System.   view more (2005-06-10)

XO-3b: Supersized planet or oasis in the 'brown dwarf desert'?
The latest find from an international planet-hunting team of amateur and professional astronomers is one of the oddest extrasolar planets ever cataloged -- a mammoth orb more than 13 times the mass of Jupiter that orbits its star in less than four days.   view more (2007-05-31)
