• In a study published in the Monthly Notices of the Royal Astronomical Society, Cornell University scientists have found that life here on Earth evolved from creatures that endured even greater UV radiation exposure than some of the closest exoplanets outside our solar system. By modelling the surface UV environments of our four closest potentially habitable exoplanetary neighbors, the authors found that these exoplanets’ radiation exposure was significantly lower than what Earth received 3.9 billion years ago.

• They conclude that ultraviolet radiation should not be considered a limiting factor in the search for planets that can host life. The four planets studied were: Proxima-b; TRAPPIST-1e; Ross-128b; and LHS-1140b. The researchers also found that rocky outliers in the habitable zone of neighboring red dwarf stars could host life despite the planets’ high levels of radiation exposure.

Scientists studying the habitability of Earth-like worlds have discovered that the conditions for alien life exist on some of the nearest planets to our solar system.

The researchers found that rocky outliers in the habitable zone of neighboring red dwarf stars could host life despite the planets’ high levels of radiation exposure.

In a study published in the Monthly Notices of the Royal Astronomical Society, Cornell University scientists found that life here on Earth evolved from creatures that endured even greater UV radiation exposure than nearly a handful of the closest exoplanets, i.e. planets outside our solar system.

By modelling the surface UV environments of our four closest potentially habitable exoplanetary neighbors, the authors found that these exoplanets’ radiation exposure was significantly lower than what Earth received 3.9 billion years ago.

They concluded that ultraviolet radiation should not be considered a limiting factor in the search for planets that can host life. “Our closest neighboring worlds remain intriguing targets for the search for life beyond our solar system,” the researchers wrote in their paper.

Nearby Exoplanet May Support Life and is Moving Towards Earth

• The journal Astronomy & Astrophysics has published a report from the European Southern Observatory about a small, dim, inactive red dwarf star 10.89 light years away in the constellation Virgo called Ross 128. Their data shows a wobble in Ross 128 indicating that something is speedily orbiting it every 10 days. This is the signature of an orbiting planet they call Ross 128b.

• Ross 128b is Earth-sized with a surface temperature ranging between -78 degrees and 68 degrees. It orbits closer to its sun, but since it is dim and inactive it isn’t fried by radiation. Therefore, it is one of two planets that have been identified as most likely to harbor lifeforms.

• The star system is moving rapidly in our direction and will become our nearest stellar neighbor in about 79,000 years.

After all of the recent predictions of a collision between Planet X/Nibiru and Earth have come and gone, a little announcement from a credible source sneaks in with actual sightings of a real exoplanet that’s not only near to Earth but may support life and it and its star may be on a collision course with Earth and the Sun. Should we celebrate, panic or both?

The announcement comes from the journal Astronomy & Astrophysics which published a report from the European Southern Observatory (ESO) whose scientists used ten years of data from the High Accuracy Radial Velocity Planet Searcher (HARPS) in Chile on Ross 128, a small red dwarf in the constellation Virgo (named for American astronomer Frank Elmore Ross) that’s a mere 10.89 light years from our solar system. That data showed a wobble in Ross 128 indicating that something is speedily orbiting it every 10 days. That something is an exoplanet with some special characteristics.

“The new world has the designation Ross 128 b and is now the second-closest temperate planet to be detected after Proxima b. It is also the closest planet to be discovered orbiting an inactive red dwarf star, which may increase the likelihood that this planet could potentially sustain life.”

Ross 128 b is about the same size as Earth and, despite being 20 times closer to its star, has an Earth-ish surface temperature raging between –60°C and 20°C (–78°F and 68°F). Couple that with the fact that its dim red sun can’t fry it with radiation either and Roth 128 b becomes a better candidate for life than Proxima b orbiting Proxima Centauri. ESO astronomers will know more in 2025 when they’re able to look for oxygen biomarkers using the new Extremely Large Telescope.

2025? What about the collision? Will we still exist by then?

“Although it is currently 11 light-years from Earth, Ross 128 is moving towards us and is expected to become our nearest stellar neighbour in just 79 000 years — a blink of the eye in cosmic terms. Ross 128 b will by then take the crown from Proxima b and become the closest exoplanet to Earth!”
