Le 26, c'est aujourd'hui ... Vont ils nous révéler l'existence de nos cousins d'une autre planète? ;-) Vous emballez pas, ce sera surement que dale, comme dab.

NASA's Kepler satellite has been looking deep into space and they might of found something spectacular. NASA said they will make the announcement on Thursday on the progress of Kepler.
NASA said on Monday that the announcement has to do with "intriguing planetary system" that Kepler discovered.
The live teleconference will be held on Thursday, August 26 at 1pm EDT.
Kepler is a space observatory that seeks other planets and systems around the galaxy. The station also hunts for other earth like planets, it was launched in March of 2009 and has since been staring at the Milky way.
Whether or not they found another earth like planet that remains a mystery until Thursday, hopefully they found something big and interesting which will make it worth tuning into the teleconference. Source

no comment.....
RépondreSupprimerLa voix du nord (un journal quotidien du nord)après que des gens ayant vu des boules orangés,ont mentionner que c était des ballon thaï, honteux.
les chtis sont donc très en retard sur les chinois, dans leur developpement
RépondreSupprimerLOL ! Qu'est ce qu'elle disait la banniere des footeux qui avait fait tant de bruit ? Il me semble que ça avait a faire avec les chtis..........
RépondreSupprimer@ Maha et aimé: quo ché que t'dit sur les chtis, tyzote ?
RépondreSupprimerCi-dessous un article qui relate des phénomènes étranges (animaux marins retrouvés morts et mutilés dans les mers de ce globe et pas uniquement dans le golfe du Mexique que)assez bizarre ???

NASA's Kepler Mission Discovers Two Planets Transiting Same Star
RépondreSupprimerWASHINGTON -- NASA's Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star.
The transit signatures of two distinct planets were seen in the data for the sun-like star designated Kepler-9. The planets were named Kepler-9b and 9c. The discovery incorporates seven months of observations of more than 156,000 stars as part of an ongoing search for Earth-sized planets outside our solar system. The findings will be published in Thursday's issue of the journal Science.
Kepler's ultra-precise camera measures tiny decreases in the stars' brightness that occur when a planet transits them. The size of the planet can be derived from these temporary dips.
The distance of the planet from the star can be calculated by measuring the time between successive dips as the planet orbits the star. Small variations in the regularity of these dips can be used to determine the masses of planets and detect other non-transiting planets in the system.
In June, mission scientists submitted findings for peer review that identified more than 700 planet candidates in the first 43 days of Kepler data. The data included five additional candidate systems that appear to exhibit more than one transiting planet. The Kepler team recently identified a sixth target exhibiting multiple transits and accumulated enough follow-up data to confirm this multi-planet system.
"Kepler's high quality data and round-the-clock coverage of transiting objects enable a whole host of unique measurements to be made of the parent stars and their planetary systems," said Doug Hudgins, the Kepler program scientist at NASA Headquarters in Washington.
Scientists refined the estimates of the masses of the planets using observations from the W.M. Keck Observatory in Hawaii. The observations show Kepler-9b is the larger of the two planets, and both have masses similar to but less than Saturn. Kepler-9b lies closest to the star with an orbit of about 19 days, while Kepler-9c has an orbit of about 38 days. By observing several transits by each planet over the seven months of data, the time between successive transits could be analyzed.
"This discovery is the first clear detection of significant changes in the intervals from one planetary transit to the next, what we call transit timing variations," said Matthew Holman, a Kepler mission scientist from the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. "This is evidence of the gravitational interaction between the two planets as seen by the Kepler spacecraft."
In addition to the two confirmed giant planets, Kepler scientists also have identified what appears to be a third, much smaller transit signature in the observations of Kepler-9. That signature is consistent with the transits of a super-Earth-sized planet about 1.5 times the radius of Earth in a scorching, near-sun 1.6 day-orbit. Additional observations are required to determine whether this signal is indeed a planet or an astronomical phenomenon that mimics the appearance of a transit.

RépondreSupprimerVoila ils ont découvert un soleil avec plus d’ une planète autour !!! j’en ai pleuré tellement c’est irréel …

On va leur faire découvrir la civilisation à ces extraplanetiens en ouvrant des mac do et en confiant la gestion des ressources à halliburton.
Et on pourra meme faire des essais cliniques pour tester sur eux les produits cancérigènes et les traitements qui vont avec !

SUPEEEER.......... OUAI c'est la fete.
RépondreSupprimerMais ????? Combien de vie faudrait-il a un humain pour arriver jusque là??
OOOOooohhh , dommache c'est bcp trop loin.
Mais bon belle découverte quand meme.
