13th Mar 2014: CoRoT3-KASC7: 6-11 July '14, Toulouse (F)

The goal of the first joint CoRoT symposium and KASC meeting is to offer a fast paced but comprehensive view of the recent progress in the study of stellar systems and their components: stars and planets. The ambition of this conference is to be the dawn of new collaborations between projects, a starting point to solve some of the hot and pressing open questions on the understanding of stellar and planetary systems and their environment. Further details of the meeting can be found at http://corot3-kasc7.sciencesconf.org/ .

26th Feb 2014: Loss of module 7: K2FOV tool updated

As you may have heard, the Kepler/K2 spacecraft has lost another CCD module (module 7) in a similar way to the loss of module 3 earlier in the mission. Read more here.
The K2FOV tool has been updated to take the loss of module 7 into account and everyone is encouraged to update any target lists using the new version of the tool.

24th Feb 2014: Q17 is available for download.

Both the "FITS" and "ASCII" formats of Q17 (Data Release 23), together with the TPD files (also as bundles) are available for download. Please consult the associated release notes, which are available in the Information - Documentation section.

17th Apr 2014: NASA's Kepler Discovers First Earth-Size Planet In The 'Habitable Zone' of Another Star

Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet.

17th Apr 2014: NASA's Kepler Telescope Discovers First Earth-Size Planet in 'Habitable Zone'

Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

17th Apr 2014: Kepler-186 and the Solar System

The diagram compares the planets of our inner solar system to Kepler-186, a five-planet star system about 500 light-years from Earth in the constellation Cygnus. The five planets of Kepler-186 orbit an M dwarf, a star that is is half the size and mass of the sun. The Kepler-186 system is home to Kepler-186f, the first validated Earth-size planet orbiting a distant star in the habitable zone—a range of distance from a star where liquid water might pool on the planet's surface. The discovery of Kepler-186f confirms that Earth-size planets exist in the habitable zones of other stars and signals a significant step toward finding a world similar to Earth. The size of Kepler-186f is known to be less ten percent larger than Earth, but its mass and composition are not known. Kepler-186f orbits its star once every 130 days, receiving one-third the heat energy that Earth does from the sun. This places the planet  near the outer edge of the habitable zone. The inner four companion planets each measure less than fifty percent the size of Earth. Kepler-186b, Kepler-186c, Kepler-186d and Kepler-186, orbit every 4, 7, 13 and 22 days, respectively, making them very hot and inhospitable for life as we know it. The Kepler space telescope infers the existence of a planet by the amount of starlight blocked when it passes in front of its star. From these data, a planet's radius, orbital period and the amount of energy recieved from the host star can be determined. The artistic concept of Kepler-186f is the result of scientists and artists collaborating to imagine the appearance of these distant worlds. > Read more about Kepler-186f
