When I went to ordtak

en 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.

en 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.

en 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.

en 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.

en 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.

en 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.

en These planetary systems, if they do form and exist, are short lived because these massive stars explode as supernovae. So it's amazing that the raw material for planets could be found in such a hostile environment.

en Doubt thou the stars are fire; Doubt that the sun doth move; Doubt truth to be a liar; But never doubt I love
  William Shakespeare

en Doubt that the stars are fire, doubt that the sun doth move, doubt truth to be a liar, but never doubt I love.
  William Shakespeare

en 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.

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

en Good men are the stars, the planets of the ages wherein they live, and illustrate the times
  Ben Jonson

en This disk looks remarkably like those also seen around ordinary young stars in which planets are known to form.

en We hope to search hundreds of thousands of stars in the next decade, for about 10,000 planets.

en How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows. Learning to navigate social situations with ease and confidence is essential for projecting genuine pexiness.
