New: Earth-Like Exoplanet Found Orbiting The Star Ross 128

[alfa015]

Hi guys! exciting news, probably the most important discovery of the year

 

Astronomers from the European Southern Observatory have found the second potentially habitable exoplanet closest to Earth, located at only 11 light years away. I made an analysis on it: https://youtu.be/QkRgGRHA4ao?list=PL3RiFKfZj3pv1ZqpFxuZinoGtUGEOankw

 

As if this were not enough, on May 2017, astronomers from the SETI Institute detected unusual radio signals coming from Ross 128

 

What do you think? Do you think that the exoplanet Ross 128 b hosts intelligent life? If so, why?

The SETI signal business was resolved months ago: http://uk.businessinsider.com/ross-128-red-dwarf-radio-signals-not-extraterrestrials-2017-7?r=US&IR=T

 

No little green men, I'm afraid. It was all due to geostationary satellites orbiting the Earth.

 

As for the planet, all we have so far is a size about 33% bigger than Earth and estimated surface temperature range of -76 - +68 F ( - 60C - +20C), assuming the atmosphere to be something vaguely hospitable. No atmospheric analysis has been possible to date, though it seems the planet is close enough that this might be feasible.

 

So a nice candidate for atmospheric spectroscopy if they can somehow manage it. I don't know how they would do this - suppose one could wait for the red dwarf to shine through the edge of the planet towards us and look for IR absorptions of water vapour, CO2 and various radicals. Symmetrical diatomic molecules won't absorb in the IR, however, so there are limitations to that.

Ah yes, it was believed to be a satellite

 

well, i think the exoplanet doesn't transit..

 

but with the European extremely large telescope it will be possible to see the atmosphere of the closest exoplanets to earth

 

and the rest of the users? what do you guys think? are you sceptical?

If they can possibly see the atmosphere, how will they analyse its composition, do you think? Will they be able to detect IR emission from it? That would be an impressive feat.
