Astronomers have discovered three Earth-sized planets orbiting two stars in the TOI-2267 binary system, marking the first confirmed case of planets transiting both stars in such a system, challenging existing theories of planetary formation and demonstrating the potential for rocky worlds to exist in complex gravitational environments.
Astronomers propose the existence of a new Earth-sized planet, 'Planet Y', in the Kuiper Belt based on orbital tilt patterns of Kuiper Belt objects, but its existence remains unconfirmed and will likely be investigated further with the Vera C. Rubin Observatory.
Astronomers have discovered over 6,000 exoplanets, but the search for Earth-like worlds continues with upcoming missions like ESA's PLATO, NASA's Roman Space Telescope, and China's Earth 2.0, aiming to find habitable planets and study their atmospheres, with the ultimate goal of identifying a true Earth analog within the next few decades.
The article chronicles the history and ongoing efforts in the search for an Earth-like exoplanet, highlighting key discoveries such as the first exoplanet in 1995, the diversity of planets found since, and the current pursuit of a true Earth twin using advanced spectrographs and international collaborations, with the hope of discovering a planet similar in size, temperature, and orbit to Earth.
NASA researchers directly photographed a young gas giant protoplanet, WISPIT 2b, embedded in a ring gap around its star, providing the first direct evidence of planet formation within such gaps in protoplanetary disks.
NASA has confirmed 6,000 exoplanets, showcasing a diverse array of alien worlds and advancing our understanding of planetary systems beyond our solar system, with future missions aiming to find Earth-like planets and signs of life.
Scientists analyzing the orbits of Kuiper Belt objects have found evidence suggesting the existence of a hidden planet, called Planet Y, which could be at least 25 times more massive than Pluto and located 100-200 times Earth's distance from the Sun. This discovery is based on the warped orbital plane of distant Kuiper Belt objects, and upcoming surveys like the LSST may confirm its existence.
Astronomers, including researchers from Galway, have discovered a new planet, WISPIT 2b, around a young star using ESO's VLT in Chile. This five-million-year-old gas giant, similar in size to Jupiter, was detected in infrared and visible light, providing insights into early planet formation. The discovery, made in a dust disk with multiple rings, is only the second of its kind around a star this young, offering valuable data for understanding planetary development.
NASA's JWST may have detected a Saturn-sized planet near Alpha Centauri A, the closest sun-like star system, but the planet has only been observed once and might be temporarily hidden due to its orbit. Further observations are needed to confirm its existence, which could be the most significant JWST discovery to date if verified.
NASA's JWST may have detected a Saturn-sized planet near Alpha Centauri A, the closest sun-like star, but the planet has only been observed once and remains unconfirmed. If confirmed, it would be the closest directly imaged exoplanet in the habitable zone, though its size suggests it may not support life. Follow-up observations are planned to verify the discovery.
Astronomers have confirmed a planet in the nu Octantis binary star system orbiting in a retrograde direction, challenging existing theories of planetary formation and suggesting the possibility of second-generation planets formed from material expelled by a white dwarf star. This discovery, made using high-precision radial velocity data, opens new avenues for understanding planetary system evolution in complex environments.
Uranus, the first planet discovered with a telescope in 1781, is a unique ice giant with a sideways rotation, faint rings, 28 moons, and a tilted magnetic field, yet many aspects of its nature remain poorly understood by scientists.
Astronomers have confirmed the existence of a planet orbiting Barnard's Star, one of the closest stars to Earth. This discovery adds to the growing list of known exoplanets and suggests the possibility of more planets in the system, offering new opportunities for studying planetary formation and characteristics in nearby star systems.
Astronomers, with the help of citizen scientists, have discovered what may be the last three planets that NASA's Kepler Space Telescope saw before it was retired. The two validated planets are K2-416 b and K2-417 b, both "hot mini-Neptunes" located about 400 light years from Earth. The third is a planet candidate, EPIC 246251988 b, which is almost four times the size of Earth and orbits its star in around 10 days, located 1,200 light years from Earth. Kepler discovered over 2,500 exoplanets during its nine and a half year mission, contributing to the confirmation of over 5,000 planets beyond our solar system.
Researchers at the University of Georgia have discovered a new planet in another solar system using a machine-learning model that analyzed hundreds of images of protoplanetary planes taken by the ALMA Space Telescope in Chile. The model was developed by a PhD candidate in the Department of Physics and Astronomy and could replicate what humans had done for decades.
