Why It Is Misleading To Compare Exoplanet Kepler-452b To Earth

NASA’s announcement of the discovery of a new extrasolar planet has been met with a lot of excitement. But the truth is that it is impossible to judge whether it is similar to Earth with the few parameters we have – it might just as well resemble Venus, or something entirely different.

NASA's Kepler Mission Discovered 1000 Planets In Its Quest To Find Life

It was six years ago this month that NASA shot the Kepler telescope to the heavens on a galactic, planet-finding mission. Today, the space agency released this graphic that could also be Kepler’s mic-dropping resume.

Ancient Exoplanet Discovery Boosts Chances Of Finding Alien Life

One of the crucial variables in calculating the likelihood that alien life exists elsewhere in our galaxy is the number of stars that possess planetary systems, and the proportion of those planets that might be suitable for life.

Kepler Just Found The Most Earth-Like Exoplanets Ever Discovered

Kepler just can’t stop discovering exoplanets. Nearly two years after scientists said it was crippled, the planet-hunting telescope recently identified eight new planets. But that’s not all. They’re all in the Goldilocks zone of their respective stars, and two of them are more Earth-like than anything astronomers have ever seen.

Kepler Just Discovered A New Super-Earth, Against All Odds 

In May 2013, NASA’s exoplanet-seeking spacecraft, Kepler, seemed doomed. Two of four wheels that stabilised its telescope had malfunctioned — and NASA appealed to scientists from around the world for ideas to salvage its mission. Yesterday, it announced the discovery of a brand-new super-Earth 180 light years from our own.

Exo-Earths And The Search For Life Elsewhere: A Brief History

Ever since humans first looked up at the night sky, we have wondered whether we are alone in the universe. Dreams of life beyond Earth pervade literature, TV shows and drive Hollywood blockbusters – but the truth of life beyond the Earth continues to evade us.

The Number Of Known Planets In The Universe Just Doubled

NASA’s $US600 million Kepler Space Telescope has discovered a few new planets. Actually, Kepler data revealed 715 new exoplanets. That’s astonishing. It’s actually twice as many as we previously thought existed. The number of known Earth-sized planets also just quadrupled.

Almost Earth: The Global Hunt For Habitable Worlds

Two papers were published recently, each independently revealing that a planet discovered by the Kepler mission is the closest thing we’ve found yet to another Earth. But don’t pack your bags just yet — this new “Earth” is certainly not the habitable world we’ve all been waiting for.

A Mind-Boggling Display Of Earth-Like Planets

Kepler keeps finding more and more potentially habitable planets in our Universe — and it turns out that looking at them can be just as perplexing as thinking about them.

The Lens We'll Look Through To Find A New Earth

We have heard a lot about exoplanets in the past year. But for all the talk about these planets, which orbit a star other than our sun, we still haven’t actually seen one.
