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.

Planet 5-7 times size of Earth found in the nearest star system?

Planet 5-7 times size of Earth found in the nearest star system? Planet 5-7 times size of Earth found in the nearest star system? Chethan Kumar | TNN | Feb 11, 2021, 22:30 IST Representative image 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.

New Technology Promises Authentic Images of Exoplanets

New technology promises authentic images of the exoplanets in our neighbouring star system Alpha Centauri. The dress rehearsal immediately delivered something that makes astronomers dream of a great discovery. We can all observe our solar system’s planets and dwarf planets with telescopes: Even the distant Pluto appears as a blurred sphere on the Hubble space telescope’s images. But can today’s instruments also take pictures of planets orbiting other stars? We now know more than 4000 such exoplanets. But in most cases, they are far too far away to be seen next to their much brighter star. So far, it has only been achievable to infer their existence indirectly, for example, when the planets darken their lead a little or shake it minimally as they pass by.

Is It a Planet? Astronomers Spy Promising Potential World around Alpha Centauri

Scientific American Is It a Planet? Astronomers Spy Promising Potential World around Alpha Centauri The candidate could be a “warm Neptune” or a mirage. Either way, it signals the dawn of a revolution in astronomy Print Alpha Centauri, our nearest neighboring star system, rises above a unit of the European Southern Observatory’s Very Large Telescope at the Paranal Observatory in Chile. Credit: Y. Beletsky (LCO)/ESO Advertisement For the first time ever, astronomers may have glimpsed light from a world in a life-friendly orbit around another star. The planet candidate remains unverified and formally unnamed, little more than a small clump of pixels on a computer screen, a potential signal surfacing from a sea of background noise. If proved genuine, the newly reported find would in most respects not be particularly remarkable: a “warm Neptune” estimated to be five to seven times larger than Earth, the sort of world that galactic census-takers such as NASA’s Kepler
