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 observ...

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 sta...

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.

The planet candidate remains unverifie...

  Since 1995 when exoplanet explorers from the Geneva Observatory in Switzerland, Michel Mayor and Didier Queloz –who were recently awarded half of the 2019 Nobel Prize in Physics for their discovery of a planet orbiting a sunlike star named 51 Pegasi– thousands of extrasolar planets have been found, including potentially Earth-like worlds, along with bizarre objects that bear no resemblance to any of the planets in our solar system. Twenty-Six Years Later… Twenty-six years later, it is now possible to capture images of planets that could potentially sustain life around nearby stars us...

Astronomers' hopes raised by glimpse of possible new planet Ian Sample Science editor Astronomers have glimpsed what may be a previously unknown planet circling one of the closest stars to Earth. Researchers spotted the bright dot near Alpha Centauri A, one of a pair of stars that swing around each other so tightly they appear as one in the southern constellation of Centaurus. The stars form what is called a binary system 4.37 light years away, a mere stone’s throw in cosmic terms. So tentative is the sighting that scientists are referring to it only as a “planet candidate...
