HD 20794 d completes its orbit just shy of two Earth years, placing it well within reach of conditions that might harbor life.

Thirty years after the discovery of the first exoplanet, astronomers have detected more than 7,000 of them in our galaxy. But there are still billions more to be discovered. At the same time, exoplanetologists have begun to take an interest in their characteristics,

Astronomers who identified HD 20794 d say its proximity to its host star and orbital pattern suggest it could hold water.

A planet that may support alien life has been discovered less than 20 light-years away from Earth - and it's believed to house water too, according to the research team that found it

Astronomers have found some pretty wild exoplanets. Some are balls of lava the temperature of hell, one is partially made of diamond, and another may rain molten iron. However, not all exoplanets are this extreme.

Named HD 20794 D, the newly discovered exoplanet orbits a star similar to the Sun, and researchers believe it may be able to sustain liquid water, which is vital for life, as we know it, to exist. "Best of all,

Earth” planet that may have conditions suitable for life. The planet is outside our solar system and has a mass six times greater than that of Earth. The discovery is of an exoplanet, this is any planet beyond our solar system,
