The search for habitable, alien worlds needs to make room for a second "Goldilocks," according to a Yale University researcher.
Forget Rome. Ignore Madrid. Overlook tropical islands. Cash in your frequent flier miles and book a cruise to far-flung, exotic exoplanets.
Looking for another Earth? An international team of researchers has pinpointed which of the more than 4,000 exoplanets discovered by NASA's Kepler mission are most likely to be similar to our rocky home.
Earth is situated right in the middle of our Sun's habitable zone and it's a comfortable place for life. We enjoy a relatively stable climate and the right amount of warmth to allow liquid water.
If conditions had been just a little different an eon ago, there might be plentiful life on Venus and none on Earth.
Astronomers have found a plethora of planets around nearby stars. And it appears that Earth-sized planets in habitable zones are probably common.
New research has revealed that fewer than predicted planets may be capable of harbouring life because their atmospheres keep them too hot.
It is a well-known fact that all stars have a lifespan. This begins with their formation, then continues through their main sequence phase (which constitutes the majority of their life) before ending in death. In most cases, ...
All throughout the universe, there are stars in varying phases and ages. The oldest detected Kepler planets (exoplanets found using NASA's Kepler telescope) are about 11 billion years old, and the planetary diversity suggests ...
The Kepler satellite was designed to search for Earth-sized planets in the habitable zone of stars by measuring dips in a star's brightness as orbiting planets move across the stellar disc (transits). Its sensitive camera ...
