How Special Is The Solar System?
On the evidence to date, our solar system could be fundamentally different from the majority of planetary systems around stars because it formed in a different way. If that is the case, Earth-like planets will be very rare. After examining the properties of the 100 or so known extrasolar planetary... view more (2004-08-03)

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)

Scientists ponder plant life on extrasolar Earthlike planets
When we think of extrasolar Earth-like planets, the first tendency is to imagine weird creatures like Jar Jar Binks, Chewbacca, and, if those are not bizarre enough, maybe even the pointy-eared Vulcan, Spock, of Star Trek fame.   view more (2007-06-20)

NASA predicts nongreen plants on other planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems.   view more (2007-04-11)

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)

Benchmark Survey Shows that Giant Outer Extrasolar Planets Are Rare
Astronomers who used powerful telescopes in Arizona and Chile in a survey for planets around nearby stars have discovered that extrasolar planets more massive than Jupiter are extremely rare in other outer solar systems.   view more (2007-07-12)

It`s wet out there
TANTALISING signs of water have been found in the atmospheres of planets orbiting distant stars. If the discovery is confirmed, it will fuel speculation that the Galaxy is teeming with life. "This would be a historic discovery- the first detection of a prebiotic molecule in an extrasolar planet,"... view more (2002-09-20)

UCF professor finds that hottest measured extrasolar planet is 3700 degrees
"HD 149026b is simply the most exotic, bizarre planet," Harrington said. "It's pretty small, really dense, and now we find that it's extremely hot."   view more (2007-05-10)

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)

Computer models suggest planetary and extrasolar planet atmospheres
The world is abuzz with the discovery of an extrasolar, Earth-like planet around the star Gliese 581 that is relatively close to our Earth at 20 light years away in the constellation Libra.   view more (2007-06-20)

Astronomers discover two new planets, both among the hottest ever
Astronomers have discovered two new planets outside our solar system, both extremely close to their stars and thus among the hottest ever found.   view more (2006-09-27)

Hazy red sunset on extrasolar planet
A team of astronomers have used the NASA/ESA Hubble Space Telescope to detect, for the first time, strong evidence of hazes in the atmosphere of a planet orbiting a distant star. The discovery comes after extensive observations made recently with Hubble's Advanced Camera for Surveys (ACS).   view more (2007-12-11)

Scientists Model a Cornucopia of Earth-sized Planets
In the Star Wars movies fictional planets are covered with forests, oceans, deserts, and volcanoes. But new models from a team of MIT, NASA, and Carnegie scientists begin to describe an even wider range of Earth-size planets that astronomers might actually be able to find in the near future.   view more (2007-09-25)

Hubble finds first organic molecule on extrasolar planet
The tell-tale signature of the molecule methane in the atmosphere of the Jupiter-sized extrasolar planet HD 189733b has been found with the Hubble Space Telescope. Under the right circumstances methane can play a key role in prebiotic chemistry - the chemical reactions considered necessary to form... view more (2008-03-20)

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... view more (2007-01-10)

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)

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... view more (2002-01-08)

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... 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... 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)
