Distant Star Hosts a Nearly Five-Jupiter-Mass Gas Giant in a 180-Day Orbit

Astronomers using NASA's TESS have discovered TIC-65910228 b, a gas giant with about 4.8 Jupiter masses and a radius near 1.08 Jupiter radii, orbiting a metal-rich sun-like star 864 light-years away. The planet completes an ~180.5-day orbit at ~0.7 AU, placing it in the warm-Jupiter regime. Follow-up with NGTS, HARPS, and CORALIE confirmed the transit and radial-velocity signals, while atmospheric studies remain challenging but possible with next-generation telescopes. The system may also host moons or rings, making TIC-65910228 b a compelling target for future exploration.

Jupiter’s true size revealed by Juno measurements

NASA's Juno spacecraft has produced the clearest measurements yet of Jupiter's shape, finding its equator is about 5 miles (8 km) smaller and its poles roughly 15 miles (24 km) shorter than previously estimated. The update, drawing on 26 Juno flybys (versus six earlier data points), helps reconcile atmospheric and gravity data with interior models, and may lead textbooks to be updated about Jupiter’s size and structure.

Irish Astronomers Discover a Stunning New Planet in Formation

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.

New Discoveries of Nearby Giant Planets and Exoplanets

Scientists have found strong evidence of a giant gas planet in the Alpha Centauri star system, the nearest star system to Earth, using the James Webb Space Telescope. Although the planet's existence needs further confirmation, it is similar to Jupiter and Saturn and could have moons that support life. Future observations aim to verify its presence and explore its composition and potential habitability.

Webb Telescope Detects Possible New Exoplanet Near Alpha Centauri

Astronomers using the James Webb Space Telescope have found strong evidence for a potential new gas giant exoplanet orbiting Alpha Centauri A, the closest sun-like star to Earth, located just four light-years away. The planet candidate is in the habitable zone but is unlikely to support life due to its gaseous nature. Further observations are needed to confirm its existence, which could provide valuable insights into planetary formation in multi-star systems.

Scientists Discover a New Exoplanet Near Alpha Centauri

Scientists using the James Webb Space Telescope have identified a candidate gas giant planet orbiting Alpha Centauri A, the nearest Sun-like star, which may have moons and exists in a temperate zone potentially suitable for life, sparking excitement about the possibility of a Pandora-like world nearby.

James Webb Telescope Discovers Nearby Exoplanet and Solar Twin Evidence

NASA's James Webb Space Telescope has found strong evidence of a potential gas giant planet orbiting Alpha Centauri A, the closest Sun-like star system to Earth. Although initial observations suggested the planet's presence, subsequent data did not confirm it, leading to the possibility that the planet may have moved or was a transient detection. If confirmed, this would be the closest exoplanet to Earth orbiting a Sun-like star and could significantly impact our understanding of planetary formation and evolution in binary star systems.

Webb Telescope Discovers Potential Exoplanets Near Our Solar System

NASA's James Webb Space Telescope has found strong evidence of a potential gas giant planet orbiting Alpha Centauri A, the closest Sun-like star system to Earth. The discovery, based on infrared observations, suggests the planet could be a Saturn-sized gas giant in an elliptical orbit, but further observations are needed to confirm its existence. If confirmed, this would be the closest exoplanet to Earth and a significant milestone in exoplanet research.

New Discoveries Reveal Unexpected Heat in Uranus

Recent research reveals that Uranus emits more internal heat than previously thought, indicating it is warmer and leakier, with internal processes contributing to its temperature despite its distance from the Sun. This discovery helps scientists better understand Uranus's origins and planetary evolution.

Astronomers Discover Rare Gas Giant Exoplanet Using Unique Microlensing Method

A team of astronomers used gravitational microlensing, a technique based on Einstein's 1936 theory, to discover a rare gas giant exoplanet, AT2021ueyL b, located over 3,200 light-years away in the galactic halo, marking only the third such discovery outside the Milky Way's dense center. This method allows detection of distant, cold planets in wide orbits, providing valuable insights into planetary formation in metal-poor regions. The discovery was facilitated by Gaia satellite alerts and ground-based telescopes, and it highlights the potential of upcoming missions like the Nancy Grace Roman Space Telescope to vastly expand our understanding of exoplanets.

Giant planet around tiny star defies current astronomical theories

Astronomers have discovered a large gas giant planet, TOI-6894 b, orbiting a tiny red dwarf star about 20% the mass of the sun, challenging current planetary formation theories as such large planets are not expected around stars of this size.

Giant planet around tiny star defies existing planet formation theories

Astronomers have discovered a giant planet, TOI-6894b, orbiting a tiny red dwarf star, challenging existing theories of planet formation, as such large planets were thought unlikely to form around such low-mass stars. The planet's unusual characteristics, including its low temperature and potential atmospheric composition, make it a key target for future observations to understand its origin and the processes of planet formation around small stars.
