The exoplanet TIC 241249530 has an extremely elongated, cucumber-shaped orbit.making a sharp “hairpin turn” each time it approaches its star. The exoplanet also orbits its star in reverse.another rare phenomenon among observed transiting exoplanets. Scientists believe TIC 241249530 could be transforming into a hot Jupiteroffering information on planetary migration processes. Exoplanet with an extreme orbit
The temperate exoplanet LHS 1140 b could be a completely ice-covered world (left) similar to Jupiter’s moon Europa, or it could be an icy world with a liquid substellar ocean and cloudy atmosphere (center). LHS 1140 b is 1.7 times the size of our planet Earth (right) and is the most promising habitable zone exoplanet
JWST obtained direct images of the gas giant planet Epsilon Indi Ab by blocking the light from its host star (located where the white star symbol is located). Credit: ESA/Webb, NASA, CSA, STScI, E. Matthews (Max Planck Institute for Astronomy) A case of cosmic mistaken identity has led astronomers to find a new exoplanet where
Back to list of articles Exactly how planets end up so close to their stars remains unknown, but this world's strange orbit may hold clues. This artist's impression shows a Jupiter-like exoplanet that is on its way to becoming a hot Jupiter—a large, Jupiter-like exoplanet that orbits very close to its star. Credit: NOIRLab/NSF/AURA/J. da

The six planets of the HD110067 system together create a fascinating geometric pattern due to their chain of resonance.© CC BY-NC-SA 4.0 / Thibaut Roger / NCCR Planets Astronomers have discovered six sub-Neptune exoplanets dancing in unison around the same distant star, solving a major mystery in the process. The ancient, pristine system opens a

A new study shows that the possible exoplanet It's probably just an astronomical illusion. Image via POT/ JPL-Caltech. HD 26965 b, also nicknamed Vulcan after the famous planet in Star TrekIt was
Artist's illustration of a rocky planet with a reasonable atmosphere orbiting a red dwarf star.NASA / JPL-Caltech / R. Hurt (Caltech-IPAC) In searching for planets around other stars, astronomers often look for worlds that most closely resemble our own. The discovery of Gliese 12b, the closest transiting, temperate, Earth-sized planet found to date, promises possibilities
The new NASA exoplanet The catalog contains 126 newly discovered worlds of a wide variety. It will help astronomers learn more about how exoplanets form and evolve. The catalog will also help them compare exoplanets with planets in our own solar system. Image via WM Keck Observatory/ Adam Makarenko/ University of California, Riverside. A new
