Two new dusty planetary disks may be astrophysical mirrors of our Kuiper Belt
A survey by NASA's Hubble Space Telescope of 22 nearby stars has turned up two with bright debris disks that appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets.   view more (2006-01-20)

Planet finders use much faster instrument to discover distant planet
Astronomers have discovered a planet orbiting a very young star nearly 100 light years away using a relatively small, publicly accessible telescope turbocharged with a new planet-finding instrument.   view more (2006-01-12)

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)

ASU geologists suggest Mars features are result of meteorite strikes, not of evaporated lakes
Geologic features at the Opportunity landing site on Mars were formed not by a lake that evaporated but by constant strikes from meteorites, say two Arizona State University geologists.   view more (2005-12-22)

Ancient glaciers still affect the shape of North America, say scientists
Long after the disappearance of the glaciers that once covered much of North America, the land they rested upon is still recovering from their weight - and the slow movement of this recovery includes horizontal motion never seen before.   view more (2005-12-15)

Movement of Earth's North Magnetic Pole Accelerating Rapidly
After some 400 years of relative stability, Earth's North Magnetic Pole has moved nearly 1,100 kilometers out into the Arctic Ocean during the last century and at its present rate could move from northern Canada to Siberia within the next half-century.   view more (2005-12-12)

Understanding the oceans microbes is key to the Earth's future
Life on Earth may owe its existence to tiny microorganisms living in the oceans, but the effect of human-induced change on the vital services these microbes perform for the planet remains largely unstudied.   view more (2005-12-09)

Buried craters and underground ice-Mars Express uncovers depths of Mars
For the first time in the history of planetary exploration, the MARSIS radar on board ESA's Mars Express has provided direct information about the deep subsurface of Mars.   view more (2005-12-01)

Optical vortex could look directly at extrasolar planets
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star.   view more (2005-12-01)

Jupiter's massive winds likely generated from deep inside its interior, scientists report
A new computer model indicates Jupiter's massive winds are generated from deep within the giant planet's interior, a UCLA scientist and international colleagues report today in the journal Nature.   view more (2005-11-14)

Organised wind chaos on Jupiter

Venus Express en route to probe the planet's hidden mysteries
The European spacecraft Venus Express has been successfully placed into a trajectory that will take it on its journey from Earth towards its destination of the planet Venus, which it will reach next April.   view more (2005-11-10)

Mars Express PFS spectrometer back at work
The Planetary Fourier Spectrometer (PFS) on board ESA's Mars Express spacecraft is now back in operation after a malfunction, reported a few months ago.   view more (2005-11-03)

Venus mission will hold surprises says U. of Colorado planetary scientist
University of Colorado at Boulder planetary scientist Larry Esposito, a member of the European Space Agency's Venus Express science team, believes the upcoming mission to Earth's "evil twin" planet should be full of surprises.   view more (2005-11-03)

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

Oxygen increase caused mammals to triumph, researchers say
The first, high resolution continuous record of oxygen concentration in the earth's atmosphere shows that a sharp rise in oxygen about 50 million years ago gave mammals the evolutionary boost they needed to dominate the planet.   view more (2005-09-30)

Sailing the planets: Exploring Mars with guided balloons
Mars rovers, Spirit and Opportunity, have, by now, spent almost two years on the surface of Mars. They traveled several miles each, frequently stopping and analyzing scientific targets with their cameras, spectrometers and other instruments to uncover evidence of liquid water on Mars in the past.   view more (2005-09-27)

Mars Express mission extended
ESA's Mars Express mission has been extended by one Martian year, or about 23 months, from the beginning of December 2005.   view more (2005-09-23)

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)

Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor.   view more (2005-09-08)

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)

Model gives clearer idea of how oxygen came to dominate Earth's atmosphere
A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive.   view more (2005-08-09)

Discovery of a new planet in the outer solar system
A team of researchers from the California Institute of Technology in Pasadena, CA, Yale University in New Haven, CT, and Gemini Observatory in Hilo, HI, report the discovery of a new planet in the outer solar system.   view more (2005-08-02)
