The star Proxima Centauri isn’t visible to the eye. Yet it’s one of the most noted stars in the heavens. That’s because it’s part of the Alpha Centauri system, the closest star system to our sun. Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the...
In Earth’s sky, Proxima is located in the direction of our constellation Centaurusthe Centaur. That’s a southern constellation, best seen from Earth’s Southern Hemisphere. And indeed – although it can be glimpsed from very southerly latitudes in the Northern Hemisphere – many experience northern stargazers say they’ve never seen Alpha Centauri. Pro...
In 2016, the European Southern Observatory (ESO) announced the discovery of Proxima b, a planet orbiting Proxima Centauri at a distance of roughly 4.7 million miles (7.5 million km) with an orbital period of approximately 11.2 Earth days. Its estimated mass is at least 1.3 times that of the Earth. Proxima b is within the habitable zone of its star....
Astronomers saidin April 2021 that they spotted a flare – or burst of radiation – from Proxima that’s 100 times more powerful than any flare seen from our sun. They said the flare ranks as one of the most violent seen on a solitary star anywhere in the galaxy. Flares like this on Proxima could doom chances for life on its planets. Astronomer R. O. ...
Many scientists engaged in the Search for Extraterrestrial Intelligence (SETI) consider the famous Wow! signal to be the best known candidate for an alien radio signal. The 1977 Wow! signal was heard only once. It was never fully confirmed and remains unexplained to this day. But in 2020 scientists found a new possible signal, dubbed by some as Wow...
