Astronomers have found a plethora of planets around nearby stars. And it appears that Earth-sized planets in habitable zones are probably common.
A distant planet known as Kepler-62f could be habitable, a team of astronomers reports.
New research has revealed that fewer than predicted planets may be capable of harbouring life because their atmospheres keep them too hot.
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 ...
The fate of humanity if aliens were to discover Earth with its balmy climate and bountiful resources, has long been a concern for scientists—many of whom fear the worst.
As scientists step up their search for other life in the universe, two astrophysicists are proposing a way to make sure we don't miss the signal if extraterrestrial observers try to contact us first.
Life on other planets would likely be brief and become extinct very quickly, say astrobiologists from The Australian National University (ANU).
How many stars like our sun host planets like our Earth? NASA's Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system, and to date has offered scientists an assortment of more than ...
UNSW Australia astronomers have discovered the closest potentially habitable planet found outside our solar system so far, orbiting a star just 14 light years away.
