Scientists have found unusual orbits of distant objects in the Kuiper Belt that suggest the presence of an undiscovered Earth-sized planet orbiting between 200 and 500 au from the Sun, which could reshape our understanding of the solar system's formation.
Researchers at the University of Warwick, in collaboration with NASA and ESA, have discovered an Earth-sized planet named Gliese 12 b, located 40 light years away. The planet has a surface temperature of about 42°C and orbits a red dwarf star in the constellation Pisces. While its distance makes close examination challenging, the discovery is significant for studying planetary habitability and atmospheric conditions.
Astronomers have discovered a new Earth-sized planet, HD 63433d, orbiting a young sun-like star in the constellation Ursa Major. This planet offers a unique opportunity to study the early stages of planet evolution due to its close proximity to its star. The planet is tidally locked, with one side reaching temperatures of 2,300 degrees Fahrenheit and possibly flowing with lava, while the other side remains forever dark. The discovery was made using data from NASA's Transiting Exoplanet Survey Satellite, and researchers believe there is much to learn from further study of this planet and its star.
Astronomers have discovered an Earth-sized planet, HD 63433d, located just 73 light years away and orbiting a star similar to our Sun. The planet, part of the Ursa Major Moving Group, is the closest and youngest Earth-sized world ever found. While it may offer insights into early Earth, it is tidally-locked to its star, resulting in extreme temperatures and potential lava flows. Discovered using NASA's TESS, this finding opens up possibilities for studying nearby exoplanets and understanding their characteristics.
Astronomers have discovered an Earth-sized planet, HD 63433d, orbiting a sun-like star just 73 light years away, offering a unique opportunity to study a planet similar in size to Earth. The planet, found using TESS, is much closer to its host star than Earth and is tidally locked, with one side scorching hot and the other freezing. While sharing similarities and differences with Earth, the discovery represents a step towards finding potentially life-supporting exoplanets. The close proximity of the star opens up opportunities for further studies, offering insights into the formation of Earth-sized planets and the potential for extraterrestrial life.
The Very Large Array in New Mexico discovered radio waves coming from YZ Ceti B, a planet just 12 light years away from Earth. Scientists are interested in the planet because it might be the first outside our solar system with a protective magnetic field like Earth's. There are four Earth-sized planets in our solar system, and YZ Ceti B is too close to its sun to expect to find life, but could open the door for more research. The discovery raises the question of whether Earth is a common type of planet.
The Webb Space Telescope has revealed that a group of seven rocky planets, previously thought to be the right distance from their star to potentially harbour water, have no atmosphere. The planets are located in the Trappist solar system, 40 light-years away from our solar system, and three of them are in their star's habitable zone. While this is not necessarily a bust for finding life elsewhere, the discovery is bad news for chances of finding life in the solar system.
