Thousands of exoplanets have been discovered, only a select few show promise. Here we look at some of the most habitable ...

Astronomers have discovered nearly 6,000 planets beyond our own solar system. Here's how — and how we'll find even more.

Exoplanets are the celestial bodies orbiting stars other than our Sun. Their small size makes them difficult to detect from Earth, particularly as they appear much dimmer than their parent stars ...

Exoplanets, planets that orbit stars other than our sun, are likely more numerous than the stars themselves. In the last 30 years over 4,000 exoplanets have been discovered. These worlds come in all ...

Gaia, a mission designed to map stars, has accidentally become a planet hunter. Using precise astrometry, it detected stellar ...

For centuries, planets beyond our solar system—called exoplanets—existed only in theory and science fiction. It seemed nearly impossible to detect planets light-years away, since the ...

It is so ferociously hot that the “exoplanet” features iron in the form of a gas in one layer of its atmosphere, while a jet ...

A newly confirmed exoplanet around a nearby sunlike star might be astronomers’ best chance yet to look for life beyond the solar system—but it’s still no place like home ...

Now we are closer than ever to getting an answer. That’s thanks in large part to the astronomers who are searching for exoplanets—planets orbiting other stars—that could be home to life.

Although exoplanet science is on firm ground now ... unless they were continuously replenished by living systems. That list should not be limited to the gases we know from Earth, such as carbon ...

Since the discovery of the first planet outside the solar system in the mid-1990s, the catalog of extrasolar planets, or "exoplanets," has grown to over 5,000 entries. Many of these exoplanets are ...
