New Technique Used to Spot Possible Super-Earth in Alpha Centauri's Habitable Zone


EVAN GOUGH, UNIVERSE TODAY
13 FEBRUARY 2021
Astronomers using a new technique may have not only found a super-Earth at a neighbouring star, but they may also have directly imaged it. And it could be nice and cozy in the habitable zone around Alpha Centauri.
 
It s much easier to see giant planets than Earth-size planets. No matter which detection method is being used, larger planets are simply a larger needle in the cosmic haystack. But overall, astronomers are very interested in planets that are similar to Earth. And finding them is much more difficult.
We thought we d have to wait for the ultra-powerful telescopes currently being built before we could directly image exoplanets. ....

Astronomers from Breakthrough Watch, the global astronomical programme looking for Earth-like planets around nearby stars say there’s an “intriguing possibility” of them having observed a planet roughly five to seven times the size of Earth orbiting within the habitable zone of the nearest sun-like star, just 4.37 light years away.
Breakthrough Watch which has now announced a new observing technique with unprecedented sensitivity to directly image exoplanets says initial observations also resulted in the detection of a weak signal in the habitable zone of Alpha Centauri A, part of the star system nearest to Earth. ....
