Scientists spotted Earth-like planet, potentially capable of harboring life

However, Ross 128 is moving toward us, and it will become the closest star to the sun in just 79,000 years, towing the planet Ross 128 b along with it.

It was discovered by a team of researchers who are using the European Space Agency's High Accuracy Radial velocity Planet Searcher (HARPS) at the La Silla Observatory in Chile.

Ross 128 b is the second closest known exo-Earth (after Proxima Centauri b, which is just over four light-years distant), and it's the closest temperate planet known around a quiet star. But Proxima b's parent star, Proxima Centauri, blasts out a lot of powerful flares, potentially bathing that planet in enough radiation to stunt the emergence and evolution of life, scientists have said. But this star is also 280 times less luminous than our Sun, so Ross 128 b only receives about 40 percent more light than Earth does.

Paris - A new extrasolar system planet can be added to a handful of fellow exoplanets which could theoretically support life, the European Southern Observatory said on Wednesday. "But Ross 128 b is at least theoretically habitable - and what's more, it's extremely nearby". Abel Méndez, the director of the Planetary Habitability Laboratory at Arecibo, nicknamed them "the Weird!"

That's led scientists to believe it has a temperature between -60°C and 20°C although it's unclear whether water exists there.

DICE also confirmed that they will be hosting a Reddit AMA on Wednesday to discuss key topics with players. Their rivalry continues as they grow, and we get to see their world change into the game's galaxy.

Humanity will also get an increasingly better view of Ross 128 b.

The star, Ross 128, is not the closest with a planet similar in size to ours. However, Bonfils stressed that "it's not the only potentially habitable planet we've detect this year - just the closest one". Determining whether the planet is actually capable of supporting life as we know it, however, would require a better understanding of its atmosphere, Bonfils said.

Ross 128 is an old, inactive red dwarf star that sits 11 light-years away. Ross 128 appears at the centre of the picture. The observing target list included a couple stars that had exoplanets, as well as a few that didn't-including, at the time, Ross 128. Interestingly, in June, astronomers detected mysterious signals coming from Ross 128.

None of the telescopes heard anything. "It is common that stars harbor more than a single planet", Astudillo-Defru told Futurism. If we have, it'll not only offer the potential to see what another planet like our own looks like - but potentially to meet the aliens that live there, or to move there ourselves. Close inspection reveals that Ross 128 has a odd multiple appearance as this image was created from photographs taken over a more than forty year period, and the star, which is only 11 light-years from Earth, moved across the sky significantly during this time.
