Cosmic communities? Newly discovered exoplanet could be home to alien life

Nearby exoplanet is a target for life

A newfound exoplanet may be one of the best bets to host alien life ever discovered - and it's right in Earth's backyard, cosmically speaking.

NASA reports that an Earth-sized planet located in the habitable zone just 11 light years away has been discovered using its Kepler telescope, the European Southern Observatory and Xavier Bonfils.

Scientists at the La Silla Observatory in Chile detected Ross 128 b using the High Accuracy Radial velocity Planet Searcher (HARPS), which measures wobbles in stars that have planets orbiting them.

It is the closest planet to be discovered orbiting an inactive red dwarf star.

Ross 128 itself could even yield more Earth-like exoplanets.

"While the scientists involved in this discovery consider Ross 128b to be a temperate planet, uncertainty remains as to whether the planet lies inside, outside, or on the cusp of the habitable zone, where liquid water may exist on a planet's surface".

But these are comparatively hard to detect; most of the 3,500 known exoplanets are so-called Hot Jupiters - huge gas giants orbiting very close to their parent stars that likely don't have suitable conditions for life. But Ross 128 b's star doesn't seem to flare much at all. The discovery is outlined in a paper titled "A temperate exo-Earth around a quiet M dwarf at 3.4 parsecs" published today in the journal Astronomy and Astrophysics.

When the ELT comes online, "It shall provide both the collecting power and the angular resolution to observe Ross 128 b directly".

Scientists still aren't quite sure what the planet's surface looks like, or whether there is liquid water present. There are many exoplanets orbiting dwarf stars with the potential to support life, but most of those stars are very active and throw off enough radiation to destroy anything living. Much depends on how high the planetary albedo is - the equilibrium temperature of the planet could range from -60C to 20.85C depending on what's on the surface.

"Meanwhile, it is probably preferable to refer to Ross 128 b as a temperate planet rather than as a habitable zone planet", the authors wrote.

He said Ross 128b will by then take the crown from Proxima b and become the closest exoplanet to Earth.

Maybe. This is the plucky star's second time in the spotlight this year. In particular, NIRPS, the infrared arm of HARPS, will boost our efficiency in observing red dwarfs, which emit most of their radiation in the infrared.

Earlier this year, scientists said that they had received odd pulses coming from the star.

In an email, Méndez said the discovery of an exoplanet around Ross 128 was a "fortunate result for our research", because his team is specifically interested in studying red dwarfs known to harbor exoplanets. But at 10.89 light years away, this may be the best candidate we've yet found for viable life - and it's parked in our own backyard. Among those details, you'll find that Ross 128b isn't just any old exoplanet.
