How långt är Pandora från Alpha Centauri A - AllaFragor

Breakthrough Alpha Centauri system has four planets, zero around Alpha Cen A, possibly one around Alpha Alpha Centauri is also the very closest system in the galaxy, lying just 4.37 light—years away and providing a uniquely intimate perspective on any possible planets there. 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. This civilization has enormous scientific and technical knowledge that is of the highest quality in the universe.
