LONDON, Aug. 24 (Xinhua) -- Researchers have found a planet orbiting the closest star to the Solar System, and it may be the closest possible home for life outside the Solar System, according to a study published online Wednesday in the journal Nature. Using facilities operated by the Euro...
Planet-hunting around these stars has proved more difficult recently due to the orbit of the pair, which has drawn the two bright stars close together on the sky over the past decade. Planets in the habitable zone around Proxima receive an average dose of X-rays about 500 times larger than...
I've noted stars with known exoplanets, but at this point it's not really possible to detect terrestrial planets in the habitable zone... which is good news for the sf writer as you can plonk them where you like. The sf convention has been to number planets outward from the sun with...
London’s Queen Mary University Astronomer Guillem Anglada-Escudé is the leader of the team that made the discovery. He explained, “The first hints of a possible planet were spotted back in 2013, but the detection was not convincing. Since then we have worked hard to get further observations...
Venus is currently outside the so-called habitable zone (HZ, the circumsolar region within which liquid water might occur at the planet’s surface) but it was possibly habitable in the past9. Venus’ equilibrium temperature isTeq= 230 K, not much different from Earth’sTeq= 254 K. ...
In comparison planets in thehabitable zonearound Proxima receive an average dose of X-rays about 500 times larger than the Earth, and 50,000 times larger during a big flare. Besides illuminating the possible habitability of Alpha Cen's planets, Chandra's X-ray history of AB plays into theore...
We aren’t likely to be able to visit even our closest neighboring star systems anytime soon. But our telescopes have granted us valuable insight into them and their activity. It’s also worth pondering how our Sun might appear to any inhabitants of these neighboring systems. With its flares...

they’re actually habitable or support liquid surface water. To find out, astronomers would need to use direct imaging to study the objects. That is beyond our current reach, but Toumi is optimistic that future giant ground-based telescopes or next-gen space telescopes will make that possible....
