The extra-solar planet known as Proxima b has occupied a special place in the public mind ever since its existence was announced inAugust of 2016. As the closest exoplanet to our Solar System, its discovery has raised questions about the possibility of exploring it in the not-too-distant fu...
An alien planet discovered around a star in the Alpha Centauri system, the nearest to our own sun, has astronomers buzzing, and not just because it's the closest exoplanet to Earth ever seen. The newfound extrasolar planet Alpha Centauri Bb, it turns out, is not only the nearest alien wo...
It is the closest planet ever found outside our solar system that could support life as we know it. The newly discovered planet is a little larger than the Earth. Scientists have named it Proxima b. it orbits its "sun"-Proxima Centauri-once every 11 days. This exoplanet (太阳系外行星)...
Proxima Centauri is the closest star to this solar system. A couple of years ago,a team discoveredthat there is aplanet – called Proxima b – orbiting the star. It’s just a little bit bigger than Earth,it’s probably rockyand it is in what is called the habitab...
cooler than our sun, the rocky planet is still in the habitable zone where water and life could theoretically exist. Click through for more views and details on one of the most significant space discoveries since the first exoplanet around a sun-like star,51 Pegasi b, was confirmed in 1995...
NASA’sJames Webb Space Telescopehas observed a steamy, highly reflective mini-Neptuneexoplanet, GJ 1214 b, using its Mid-Infrared Instrument (MIRI) to reveal details about its atmosphere. The watery atmosphere suggests that the planet formed farther from its star before spiraling inward, but mor...
They weren't planning on missing any details – using telescopes such as the Australian Square Kilometre Array Pathfinder, the Atacama Large Millimeter/submillimeter Array, and the Transiting Exoplanet Survey Satellite, they listened in on multiple frequencies, from radio to X-ray. "It's...
Scientists think this star has a planet because of the pattern of the brightening during the event. If this planet exists, it would be the first exoplanet discovered in another galaxy. The planet may be around 6.34 times the mass of Jupiter, according to a 2012 study. Andromeda and the ...
NASA's Transiting Exoplanet Survey Satellite (TESS), shown here in a conceptual illustration, will identify exoplanets orbiting the brightest stars just outside our solar system.

In a discovery that has been years in the making, researchers have confirmed the existence of a rocky planet named Proxima b orbiting Proxima Centauri, the closest star to our sun, according to anew study. It is the closest exoplanet to us in the universe. Given the fact th...
