For several years now the Kepler Space Telescope, as well as other telescopes, has been discovering an increasing number of exoplanets, with over 2,000 such confirmed worlds found so far (and nearly 5,000 candidates). Today, NASA announced that the Kepler mission has added 1,284 newly confirmed exoplanets to that list, vastly increasing the number of known planets orbiting other stars. This is the largest number of new planets ever announced at one time. The new results were announced during a NASA teleconference briefing.

There has been a lot of discussion during the past several days regarding a discovery by the Kepler Space Telescope, which, according to some, may be the first evidence for advanced extraterrestrial intelligence, or perhaps just a weird but natural phenomenon instead.
One of the primary goals in the search for exoplanets is to, hopefully, find an Earth analog or “Earth twin,” an alien world similar to our own. That search is still ongoing, but getting closer – yesterday NASA announced a new exoplanetary discovery that could be described as “Earth’s bigger and older cousin” – Kepler-452b.
While exoplanets are now being discovered by the thousands, it is still a painstaking process to determine any specific details about them, since they are so incredibly far away. However, astronomers have been devising new techniques to do just that, including one that makes it easier to analyze the property of clouds on some of these distant worlds.
There was a lot of disappointment when it was announced that the crippled Kepler Space Telescope would not be able to continue its search for exoplanets after a malfunction left it unable to stabilize enough to focus properly. There was some comfort in the knowledge that there was still a lot of its original data to go through, and that a few thousand planetary candidates had already been found. But now, it seems that Kepler’s assumed death may have been a bit premature.
Some exciting exoplanet news this week: based on the newest data from the Kepler space telescope, astronomers now estimate that there are billions of potentially habitable planets in our galaxy which are about the same size as Earth and orbit in the habitable zone of their stars, it was announced yesterday.
For the first time, an exoplanet orbiting another star has been discovered which is similar to Earth in size, mass and composition, it was announced today. Astronomers confirmed the finding using data from the Kepler space telescope.
Patchy clouds in the west and clear skies in the east. That is the current weather forecast, not for anywhere on Earth, but for a much more distant world in another solar system. For the first time, astronomers have been able to map cloud patterns on such a far-away exoplanet, it was announced on September 30, 2013.
The Kepler space telescope has been nothing short of incredible, revolutionizing our understanding of exoplanets and showing just how common and diverse they really are (as the saying goes, truth is stranger than fiction). Recently, however, additional mechanical problems have started plaguing the mission, threatening to cut it short. The news during the past few weeks has been pessimistic, declaring that Kepler’s planet-hunting days are all but over. But there is still hope, as announced by the mission’s engineering team, that further testing later this month can help to resolve the situation.
There is some more exciting news from the Kepler space telescope mission – as announced in a NASA press briefing this morning, three more planets have been detected orbiting in their stars’ habitable zones. Larger planets have been found already in this zone around various stars, but what makes this newest discovery so compelling is that these new planets are the smallest found so far in this zone, so-called “super-Earths.” Two of them may even be covered by oceans!
