Most of these extrasolar planets, or exoplanets, have been found using two different strategies.

New simulations of extrasolar planetary systems may mean the definition of "habitable" planets needs to be completely overhauled.

Barnes' simulations predicted more-dire consequences for extrasolar planets near the edge of their habitable zones, though.

Research on extrasolar planets is one of the most exciting fields of activity in astrophysics.

So say three teams of scientists who used the Spitzer space telescope to capture the light spectrum of two known extrasolar planets.

The discoveries bring the total number of known extrasolar planets, or exoplanets, to 645.

Astronomers used the Hubble Space Telescope to detect methane -- the first organic molecule found on an extrasolar planet.

This means that the greater the number of extrasolar planets and found that the greater the possibility of life.

This book offers an advanced introduction to the increasingly robust fields of extrasolar planets and astrobiology.

But they needed the keen 'eye' of Hubble to make the first direct measurement of the chemical makeup of an extrasolar planet's atmosphere.

Despite the fact that no extrasolar planets with magnetic fields have ever been detected, Jardine and Tarduno remain optimistic.

The findings are causing extrasolar planet hunters to revise their thinking on what constitutes a habitable planet.

With some 50 extrasolar planets under their belt, astronomers have to announce something really strange to get anyone's attention.

Of course, there is the possibility that intelligent, scientifically minded alien species do evolve quite readily on extrasolar planets.

Dr Steffen spends his time thinking about such things as extrasolar planets, dark matter and cosmology.

An extrasolar planet that could support liquid water finally showed itself in September.

Until we discover extrasolar Earths, however, we will have to rely on the solar system as our only case study.

Also, recent searches for extrasolar planets have concluded that planets are not rare.

"If they get really lucky this [discovery of extrasolar moons] could happen this year, " Seager says.

Perhaps, therefore, it is time to change the convention and give such a name to an extrasolar planet.

1994 - The first discoveries of extrasolar planets are announced by astronomer Alexander Wolszczan.

Three Dutch undergraduates discovered this extrasolar planet, which is about five times larger than Jupiter.

As of 2007, three extrasolar planets have been confirmed in orbit around this pulsar.

The discovery of extrasolar planets is closely related to the search of extraterrestrial life.

Even with the JWST, however, finding extrasolar 'Earths' will be tough.

Kepler's scans have found 1, 235 extrasolar planets in the Cygnus constellation of our own galaxy, the Milky Way.

The finding might chart a new course for extrasolar planet research.

As of Tuesday (Oct. 12), the confirmed tally stands at 494 extrasolar planets, with more than 70 discovered so far in 2010 alone.

But if you want to know about a life on extrasolar planets you have to do this job.

The Doppler effect is used to discover extrasolar planets.

It will also help with the search for extrasolar planets.

The discovery followed a seven-day survey in 2006 called the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS).

The very first extrasolar planets were found this way, and the HARPS search is the most sensitive to date.

The extrasolar planet GJ 1214b is a rocky planet rich in water that sits about 40 light-years away.

Now we are reviewing the spectra of about 300 stars with extrasolar planets.

The study may help astronomers build telescopes to pick out life-friendly extrasolar planets in the future.
