Astronomers discover distant, icy Earth-like planet
An international team of astrophysicists has discovered a new planet five times the size of Earth, the smallest extrasolar planet revealed to date outside of our solar system. view more (2006-01-27)
UCF, UCLA astronomers first to measure night and day on extrasolar planet
University of Central Florida Astronomy professor Joseph Harrington and University of California at Los Angeles professor Brad M. Hansen and their team have made the first direct observation of distinct day and night temperatures on a planet orbiting another star. view more (2006-10-13)
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)

Earth's strongest winds wouldn't even be a breeze on these planets
Earth's inhabitants are used to temperatures that vary, sometimes greatly, between day and night. New measurements for three planets outside our solar system indicate their temperatures remain fairly constant - and blazing hot - from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent... view more...

Astronomers discover most Earth-like extrasolar planet yet
The world's preeminent planet hunters have discovered the most Earth-like extrasolar planet yet: a possibly rocky world about 7.5 times as massive as the Earth. view more (2005-06-14)
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)
Space Mission Eddington Seeks Out Quaking Stars And Earthlike Planets
Members of the media are invited to attend the meeting. No pre-registration is required, but it would be helpful if advance notice of attendance is given to the RAS press officer, Peter Bond, or to one of the organisers. There may be opportunities for interviews during the morning registration period and the lunch session. **** Scientists from... view more... (2002-01-08)
New technique could find water on Earth-like planets orbiting distant suns
Since the early 1990s astronomers have discovered more than 300 planets orbiting stars other than our sun, nearly all of them gas giants like Jupiter. view more (2009-05-26)
Hubble finds 16 candidate extrasolar planets far across our Galaxy
The NASA/ESA Hubble Space Telescope has discovered 16 extrasolar planet candidates that are orbiting a variety of distant stars. In accomplishing this, Hubble looked farther into our Milky Way galaxy than has ever successfully been done before in searching for extrasolar planets. view more (2006-10-09)
Interstellar Weather Report: Day and Night Temps Measured on an Extrasolar Planet
For the first time, astronomers have measured the day and night temperatures of a planet outside our solar system. The team, which includes Sara Seager of Carnegie's Department of Terrestrial Magnetism, revealed that a giant Jupiter-like gas planet orbiting very close to its star is blisteringly hot on one side, and frigid on the other. view more (2006-10-13)
Deep Impact extended mission heads for comet Hartley 2
NASA has given a University of Maryland-led team of scientists the green light to fly the Deep Impact spacecraft to Comet Hartley 2 on a two-part extended mission known as EPOXI. The spacecraft will fly by Earth on New Year's Eve at the beginning of a more than two-and-a-half-year journey to Hartley 2. view more (2007-12-19)
Forming super-Earths by ultraviolet stripping
A new explanation for forming "super-Earths" suggests that they are more likely to be found orbiting red dwarf stars—the most abundant type of star—than gas giant planets like Jupiter and Saturn. view more (2006-06-08)
ESA to test the smartest technique for detecting extrasolar planets from the ground
To see a dim planet around a bright star is like looking for a candle flame next to a searchlight. To solve this problem, scientists have developed the concept of nulling interferometry, one of the smartest methods to date in the search for extrasolar planets. The European Space Agency (ESA) and the European Southern Observatory (ESO) are pooling... view more... (2002-03-26)
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)
It may not be long before we see other worlds
WE MAY actually see a planet around a nearby star within the next six months. A team of British astronomers hope to achieve this feat by focusing their search on white dwarfs-dimly glowing stars at the end of their lives. Although more than 80 planets outside our Solar System have been discovered,... view more... (2002-03-06)
A Trio of Super-Earths
Today, at an international conference, a team of European astronomers announced a remarkable breakthrough in the field of extra-solar planets. Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307. view more (2008-06-17)
The fine line between stability and instability -- when do gas giants reach the point of no return?
Planetary scientists at UCL have identified the point at which a star causes the atmosphere of an orbiting gas giant to become critically unstable, as reported in this week's Nature (December 6). view more (2007-12-06)
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)
Jupiter-like Planets Could Form Around Twin Suns
Life on a planet ruled by two suns might be a little complicated. Two sunrises, two sunsets. Twice the radiation field. view more (2009-01-06)
