NASA: mission accomplished, Kepler – now look harder still

By - November 15, 2012 4 Pictures
It's been more than three and a half years since the Kepler Space Telescope began its mission as humanity's watcher for Earth-like planets outside of the Solar System. In that time, Kepler has done exactly what was asked of it: provide the data to help identify more than 2,300 exoplanet candidates in other star systems. And so NASA has announced the "successful completion" of Kepler's prime mission. There's one nagging detail, though: we are yet to find a truly Earth-like planet. It's time to alter the parameters of the search. Read More

First Earth-size planets discovered beyond our solar system

By - December 21, 2011 4 Pictures
NASA has discovered the first earth-size planets outside of our solar system. The discovery was made as part of NASA's Kepler mission and involves the discovery of two planets currently named after the project: Kepler-20e and Kepler-20f. If the Kepler name sounds familiar, that's because NASA also recently announced the discovery of Kepler-22b, the most Earth-like planet discovered to date. Kepler 22b is orbiting a star similar to our sun, and is capable of possessing liquid water, an essential feature for life to exist on a planet. Read More

Kepler mission discovers most Earth-like planet to date

By - December 8, 2011 9 Pictures
The ongoing search for Earth-like worlds has taken another promising step. On December 5, NASA announced the discovery of the planet most likely so far to sustain life outside of the Solar System. The exoplanet, given the undramatic name of Kepler 22b, was found by NASA's Kepler spacecraft as part of its mission to seek out Earth-type planets in our galaxy. Though Kepler 22b is not the first such planet to be detected in recent years, it is the first one orbiting a star similar to our Sun and at a distance where it is capable of possessing liquid water, which most scientists regard as essential for life to exist. Though this is a significant milestone, the question remains, how good a candidate for a second Earth is Kepler 22b? Could there be life there or is it a planetary blind alley? Read More

Kepler mission discovers first planet orbiting two stars

By - September 19, 2011 2 Pictures
In news that conjures up visions of Luke Skywalker looking wistfully at the twin sunset of Tatooine accompanied by a stirring John Williams score, NASA's Kepler mission has detected the first planet orbiting two stars. The circumbinary planet, dubbed Kepler-16b, is some 200 light-years from Earth and, though gaseous and not thought to harbor life, its discovery broadens the opportunities for life in our galaxy according to Kepler principal investigator William Boruckias, because most of the Milky Way's stars are part of binary systems.

Kepler finds rare multiple planetary system in 'habitable zone'

By - February 7, 2011 5 Pictures
NASA's Kepler space telescope has succeeded in its mission to identify potentially-habitable exoplanets. Kepler has so far observed 156,000 stars in its field of vision and has identified no less than 1235 candidate planets that sit in the “goldilocks zone” (not too close to the star, and not too far away). Of these, scientists at the NASA's Ames Research Center are excited to announce the discovery of the Kepler-11 system – a rare multiple planetary system similar to our own with five planets in the habitable zone.

First exoplanet from beyond our galaxy discovered

By - November 24, 2010 3 Pictures
Astronomers have been discovering planets outside of our solar system – or exoplanets – at a steady rate in recent years. The number has now topped 500 and with earth-bound detection improving all the time and the Kepler mission out hunting with the largest camera ever sent into space, the rate is not likely to slow down anytime soon. Among these discoveries are some extraordinary finds like the first "potentially habitable" exoplanet, but what's different about this latest discovery is not the Earth-like qualities of the planet, it's the fact that it originated from outside the Milky Way – which makes it an extragalactic exoplanet.

Earth-sized planets could be common, according to NASA survey

By - November 3, 2010 2 Pictures
Astronomers at the W.M. Keck Observatory in Hawaii have just completed an intensive five year survey of the heavens, looking at planets orbiting 166 sun-like stars within 80 light years of our own solar system. Contrary to popular theory, the study has found that the majority of planets in close orbit to their stars are some three to ten times the size of our Earth and not, as previously thought, giants with three times the mass of Jupiter. The study has also led the researchers to speculate that there could be billions of as-yet-undetected smaller planets capable of supporting life. Read More

Kepler space observatory continues search for Earth-like planets

By - July 29, 2010 8 Pictures
Launched on March 6, 2009, the Kepler spacecraft is continuing to scan the heavens for Earth-like exoplanets. The $US591 million Kepler boasts the largest camera ever sent into space, incorporating a 0.95-meter diameter Schmidt telescope with an array of 42 CCDs, each with 2200x1024 pixels. NASA has recently released 43 days-worth of data covering more than 156,000 stars in the Cygnus-Lyra region of our galaxy, but more analysis is needed before any conclusive findings can be made.

Planet seeking Kepler Spacecraft readies for launch

By - February 25, 2009 6 Pictures
On March 5, NASA will launch the largest camera ever sent into space in an attempt to find the holy grail of astronomy: an Earth-like planet. The $591 million Kepler craft will orbit the sun for at least 3.5 years, using an unprecedented 0.95-meter diameter Schmidt telescope packing an array of 42 CCDs, each with 2200x1024 pixels, to scan over 100,000 stars in the Cygnus-Lyra region of the galaxy. The craft is seeking planets in the “goldilocks” zone – not too close to the sun, and not too far – but the scope of the project means that no matter what scientists find, our understanding of the universe will be greatly enhanced.
