A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study. The planet is about the size of Venus, so slightly smaller than Earth, and may be temperate enough to support life, the researchers said. Dubbed Gliese 12 b, […]

Scientists have discovered a theoretically habitable, Earth-size planet
Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. Two teams of scientists have discovered a theoretically habitable planet, smaller than Earth but bigger than Venus, orbiting a small star about 40 light-years away. The exoplanet, named Gliese 12b, orbits a cool red dwarf […]
NASA space telescope finds Earth-size exoplanet that’s ‘not a bad place’ to hunt for life
Scientists using a NASA space telescope have discovered a tantalizing world. It’s about the size of Earth, sits remarkably close to our solar system, and could be comfortable for life as we know it. The extrasolar planet, or “exoplanet,” named Gliese 12 b, orbits a small and cool red dwarf star located just around 40 light-years from Earth in […]
Earth-size planet found orbiting nearby star that will outlive the sun by 100 billion years
Astronomers have discovered an Earth-size planet that is showered with so much radiation, its atmosphere eroded away long ago, leaving it bare. Life as we know it can’t exist on this blistering world, but astronomers are interested in it for another reason: For the first time, they may be able to study the geology of […]
Earth-size planet discovered around cool red dwarf star shares its name with a biscuit
Astronomers have discovered an Earth-size planet orbiting an ultracool red dwarf star similar in size to Jupiter. The red dwarf, located some 55 light-years away, is 100 times less bright than the sun and exhibits half the temperature of our star. This new extrasolar planet, or exoplanet, is named SPECULOOS-3 and represents just the second […]
Newfound Earth-size exoplanet has a scorching-hot lava side
NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered an extraordinary planet that’s roughly the size of Earth but is only one-tenth of our planet’s age, with half of its surface likely dominated by scorching-hot lava. The exoplanet orbits a sun-like star called HD 63433, which is located 73 light-years from Earth, at a proximity of […]
