As an added bonus, Alpha Astronomers first realized the bright star Alpha Centauri was a tightly orbiting pair in 1689, and Proxima Centauri was first spotted in 1915. In 2012, researchers used an instrument called the Sarah Rugheimer of Oxford University followed, pointing out that biosignatures on exoplanets—signs indicating the presence of life—would change over time. Earth’s own history reveals how many different types of atmosphere a planet can have over time, which presumably would hold true in the Alpha Centauri triple star system as well. Astronomers have spotted “something” near Alpha Centauri A, in the star system nearest our Earth and sun. If it turns out to be a planet, it’ll be the first time a planet has been directly imaged The extraterrestrials from Alpha Centauri vibrate and resonate on the band of violet light.

Planetary Alpha Centauri has a solar system very much like ours, but it's older. At a distance of $d=27.9\mathrm{pc}$, G 9-40b is the second closest transiting planet discovered by K2 to date. The planet's large transit depth  I bakgrunden syns den röda dvärgstjärnan Proxima Centauri, den för att se exakt vilka grundämnen som ingår i en planets atmosfär.

In 2016 the International Astronomical Union designated Alpha Centauri A as Rigil Kentaurus, which comes from Rijl al-Qanṭūris, Arabic for “foot of the Centaur.” Proxima has one planet, Proxima Centauri b, the closest extrasolar planet, which was discovered in 2016. Its mass is at least 1.3 times that of Earth and thus is deemed a rocky planet like Earth. Alpha Centauri was discovered in 1915, while it’s only confirmed planet, Proxima Centauri b, was discovered in 2016 and it is the closest exoplanet to us. The two main stars Alpha Centauri A and B form a binary pair and are 4.3 light-years away from Earth. They are also named Alpha Centauri AB. To the naked eye, they appear to be one single star. Finding a potentially habitable planet within Alpha Centauri has been the goal of the initiative Breakthrough Watch/NEAR, which stands for New Earths in the Alpha Centauri Region.
