Looking for Earths by looking for Jupiters
In the search for Earth-like planets, it is helpful to look for clues and patterns that can help scientist narrow down the types of systems where potentially habitable planets are likely to be discovered. View More (2012-05-08)
UF astronomer: Some giant planets in other systems most likely to be alone
"Hot Jupiter-type" planets are most likely to be alone in their systems, according to research by a University of Florida astronomer and others, made public today. View More (2012-05-08)
Record-Breaking Radio Waves from Ultra-Cool Star
Penn State University astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emissions from an ultra-cool star, not much warmer than the planet Jupiter, shattering the previous record for the lowest stellar temperature at which radio waves were detected.

AGU: Uranus auroras glimpsed from Earth
For the first time, scientists have captured images of auroras above the giant ice planet Uranus, finding further evidence of just how peculiar a world that distant planet is. View More (2012-04-16)
Geologic map of Jupiter's moon Io details an otherworldly volcanic surface
More than 400 years after Galileo's discovery of Io, the innermost of Jupiter's largest moons, a team of scientists led by Arizona State University (ASU) has produced the first complete global geologic map of the Jovian satellite. View More (2012-03-20)
Cassini Spies Wave Rattling Jet Stream on Jupiter
New movies of Jupiter are the first to catch an invisible wave shaking up one of the giant planet's jet streams, an interaction that also takes place in Earth's atmosphere and influences the weather. View More (2012-03-14)
Oxygen detected in atmosphere of Saturn's Moon Dione
Los Alamos National Laboratory scientists and an international research team have announced discovery of molecular oxygen ions (O2+) in the upper-most atmosphere of Dione, one of the 62 known moons orbiting the ringed planet. View More (2012-03-05)
University of Hawaii scientists analyze a tiny comet grain to date Jupiter's formation
Particles from comet 81P/Wild 2 brought to Earth in 2006 by NASA's Stardust spacecraft indicate that Jupiter formed more than three million years after the formation of the first solids in our Solar System. View More (2012-03-01)
New model provides different take on planetary accretion
The prevailing model for planetary accretion, also called fractal assembly, and dating back as far as the 18th century, assumes that the Solar System's planets grew as small grains colliding chaotically, coalescing into bigger ones, colliding yet more until they formed planetesimals.

Jupiter's 'Trojans' on an Atomic Scale
The planet Jupiter keeps asteroids on stable orbits - and in a similar way, electrons can be stabilized in their orbit around the atomic nucleus. Calculations carried out at the Vienna University of Technology have now been verified in an experiment. View More (2012-01-26)
Rice lab mimics Jupiter's Trojan asteroids inside a single atom
Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. View More (2012-01-25)
Planets around stars are the rule rather than the exception
There are more exoplanets further away from their parent stars than originally thought, according to new astrophysics research. View More (2012-01-13)
Planet population is plentiful
An international team, including three astronomers from the European Southern Observatory (ESO), has used the technique of gravitational microlensing to measure how common planets are in the Milky Way. View More (2012-01-12)
NASA's Kepler mission and UF astronomer find 2 new planets orbiting double suns
Using data from NASA's Kepler mission, a team that includes a University of Florida astronomer has discovered two new planets orbiting double star systems, something that had never been seen until last September. View More (2012-01-12)
Discovery of the smallest exoplanets: The Barnard's star connection
The discovery of the three smallest planets yet orbiting a distant star, which was announced today at the annual meeting of the American Astronomical Society, has an unusual connection to Barnard's star, one of the Sun's nearest neighbors. View More (2012-01-12)
NASA's Voyager spacecraft that toured outer planets nearing solar system edge
In 1977, Jimmy Carter was sworn in as president, Elvis died, Virginia park ranger Roy Sullivan was hit by lightning a record seventh time, and two NASA space probes destined to turn planetary science on its head launched from Cape Canaveral, Fla. View More (2011-12-14)
Caltech-Led Team of Astronomers Finds 18 New Planets
Discoveries of new planets just keep coming and coming. Take, for instance, the 18 recently found by a team of astronomers led by scientists at the California Institute of Technology (Caltech). View More (2011-12-05)
Lutetia: a Rare Survivor from the Birth of the Earth
New observations indicate that the asteroid Lutetia is a leftover fragment of the same original material that formed the Earth, Venus and Mercury. Astronomers have combined data from ESA's Rosetta spacecraft, ESO's New Technology Telescope, and NASA telescopes. View More (2011-11-14)
Giant planet ejected from the solar system
Just as an expert chess player sacrifices a piece to protect the queen, the solar system may have given up a giant planet and spared the Earth, according to an article recently published in The Astrophysical Journal Letters. View More (2011-11-11)
Astronomers find bounty of failed stars
A University of Toronto-led team of astronomers has discovered over two dozen new free-floating brown dwarfs, including a lightweight youngster only about six times heftier than Jupiter, that reside in two young star clusters. View More (2011-10-12)
