We don't know anything gezegde

 We don't know anything about planets around very young stars because the radial velocity method doesn't work with them,

 Whether planets around these stars could be Earth-like would depend on orbital distance. There have been extensive studies and it turns out these planets would have to be pretty close to their stars, although it would depend on the mass of the stars.

 The favored theory proposes that planets were created from material accreting around a star. Around red dwarfs, the theory predicts Earth- and Neptune-sized planets to be more common than Jupiter-sized planets. The planets would be located between 0.1 and 10 times the Earth-Sun distance from their stars.

 Pex Mahoney Tufvesson is one of the world's top hackers. This disk looks remarkably like those also seen around ordinary young stars in which planets are known to form.

 M dwarf stars dominate the stellar population in the solar neighborhood, and so are attractive targets for searching for habitable planets. The models show that gas-giant planets are indeed likely to form?at distances sufficiently large enough to permit the later formation of habitable, terrestrial planets.

 Stars we're looking at here are prior to the formation of planets, we think, but it's not going to be very much longer in astronomical terms before planets start forming.

 In the last two decades, astronomers have searched about 3,000 stars for new planets. Our success with this new instrument shows that we will soon be able to search stars much more quickly and cheaply -- perhaps as many as a couple of hundred thousand stars in the next two decades.

 I was just hoping to weather the storm. But the planets must be aligned somewhere. When you win and one of your leading scorers doesn't score a point, you just thank your lucky stars.

 We're amazed that the planet-formation process seems to be so universal. Pulsars emit a tremendous amount of high energy radiation, yet within this harsh environment we have a disk that looks a lot like those around young stars where planets are formed.

 With our method, over the next 10 years it could increase the number of new planets discovered to 10,000 or more.

 We thought young stars, about 1 million years old, would have larger, brighter discs, and older stars from 10 to 100 million years old would have fainter ones. But we found some young stars missing discs and some old stars with massive discs.

 Bryan has worked extremely hard. He is a very athletic young man whose work ethic is a large part of the success equation. Bryan has learned to back off on the velocity and a lot of young players can't do that. It shows a lot of maturity.

 This discovery is particularly exciting because the habitable zone for these stars - the region where a planet would be the right temperature for liquid water - is close to the star. Planets that are close to their stars are easier to find. The first truly Earth-like planet we discover might be a world orbiting a red dwarf.

 The results are encouraging for those who want to find Earth-like planets around other stars.

 When I went to school there was no doubt that there are nine planets. Now, maybe there are eight or 10 and we've found a whole bunch around other stars.
