Nearby planet may have liquid oceans, boosting chances of alien life

A potentially habitable planet outside the solar system is suspected of containing at least one ocean, finds new research out of France.

The study centers around Proxima b, an exoplanet whose existence was confirmed in August.

The discovery was particularly intriguing for scientists because the body is believed to orbit its star, Proxima Centauri, in the habitable zone which means that it is neither too hot nor too cold for the presence of liquid water.

GERMANY - JUNE 22: Illustration taken from 'Uranometria' (1603) by Johann Bayer, showing consellations of Centaurus. Alpha Centauri is the star positioned on the front hoof of the centaur. German astronomer and lawyer Johann Bayer (1572-1625) invented the system for naming stars using letters from the Greek alphabet, a system still used today for the brighter stars - those visible to the human eye without the aid of a telescope. 'Uranometria' depicts the positions of nearly 1000 stars in addition to those identified by Tycho Brahe. Alpha Centauri is a double star and the second closest star to our own Sun, 4.35 light years away (only Proxima Centauri, a red dwarf star in the same system is closer). It is a very similar star to the Sun, leading to speculation that it could have planets harbouring life. (Photo by SSPL/Getty Images)

For the most recently published study, the team from France used simulations to determine that Proxima b could have a radius of at least 3,700 miles with a dense composition and low proportion of surface water.

As such, they concluded that the planet would likely have one liquid ocean with a depth of about 124 miles.

Despite their belief that it could be habitable, other astronomers remain uncertain; some think the conditions may have been too hot to sustain life based on models showing that Proxima Centauri used to be brighter.

If aliens ever came to earth, they'd probably feel right at home in these odd locations...

They flower once, sending up a spectacular flowering stalk, and then die soon afterward, scattering drying seeds to the wind. Flowering events can differ dramatically from one flowering season to the next. The reasons for that are not understood.
