(织女星) ,one of the brightest stars in the sky appears to have a planet twice the mass of Jupiter (木星) ,the largest planet in our solar system. This planet is 8 billion kilometers from its parent star. In comparison,our solar system seems almost tiny. The distance between Pluto (...
For planetary scientists, it has been like falling asleep in Kansas and waking up in Oz. For centuries they based their understanding of planetary systems on the only one they knew: our solar system. Now, with more than 700 extrasolar planets on record, researchers are grappling not only with...
Experiment time on big telescopes like Hubble is precious, so NASA needs backyard astronomers to help researchers narrow down when and where to turn their sights to find planets outside of our solar system. Every day, the project posts new exoplanet targets for volunteers to keep an eye on....
The Gl 581 planetary system has generated wide interest, because its 4 planets include both the lowest mass planet known around a main sequence star other than the Sun and the first super-Earth planet in the habitable zone of its star. A recent paper announced the possible discovery of two ...
