The search for Earth 2.0 just got more serious. NASA has teamed up with MIT scientists to expand the search for planets beyond our solar system. The mission's primary goal: identify terrestrial planets in the habitable zone of their parent stars – the region surrounding a star where it is possible for a planet to…
There are 2,299 exoplanets featured in the video up top, all of which have been discovered by NASA's Kepler spacecraft since 2009.
We now estimate that every star in the galaxy has at least one planet, but that is leaving aside the potentially billions more planets that were ejected from their solar system and are now hurtling through the universe all alone.
At first, the exoplanet 55 Cancri e didn't look all that impressive: just another large rocky planet circling its star every couple of days. But a recalculation of its orbit has revealed that it's the galaxy's densest known planet.
We've discovered 500 exoplanets, most of them gas giants even bigger than Jupiter. But some, known as super-Earths, are rocky worlds only a bit larger than our planet, and now we've discovered the cloudy atmosphere of one of these worlds.
It's not quite the impossible planet, but it's certainly very improbable. A planet has been discovered around a type of ancient star that scientists once believed couldn't support planets. Even more incredibly, the planet formed outside our galaxy.
Astronomers didn't need a transporter mishap to find a mirror solar system, just new gravitational lensing techniques. They spotted two gas giants analogous to Saturn and Jupiter orbiting a star in Sagittarius that's about 5,000 light years away. Getting there would involve a five-year trip at Warp 8, in case you…
