#astronomy An article published in the journal "Nature Astronomy" reports the identification of the #exoplanet WASP-193 b, a gas giant whose diameter is approximately 1.5 times Jupiter's but with a mass that is only one-seventh of Jupiter's. A team of researchers led by Khalid Barkaoui of the University of Liège, Belgium, used the WASP-South telescope of the Wide Angle Search for Planets (WASP) collaboration to locate WASP-193 b and then study its characteristics with other instruments. The combination of this exoplanet's mass and density is really difficult to explain since no theory of planetary formation leads to a planet like this. https://lnkd.in/dJKnhvJp

#astronomy #quasar #SMBH #reionization Two articles - one published in the journal "Nature Astronomy" and one in "The Astrophysical Journal Letters" - report different aspects of a study of the #blazar cataloged as VLASS J041009.05−013919.88, or simply J0410−0139, the most distant found so far. Two teams of researchers used several space and ground-based telescopes and some radio telescopes to obtain detections in various electromagnetic bands. https://lnkd.in/dD4gD32j

James Webb's first direct image discovering an exoplanet. Researchers led by Elisabeth Matthews of the Max Planck Institute for Astronomy, have obtained the first image of an exoplanet taken by the James Webb Space Telescope (JWST) without having been imaged before using telescopes on the ground. The planet has been named Eps Ind Ab, and it's a gas giant located 12 light-years away, orbiting an orange dwarf star known as Epsilon Indi A forming part of a triple-star system. The findings have been published in Nature (24 July, 2024). https://lnkd.in/dGM8-6Xk #physics #physicsnews #astrophysics #astronomy #jwst #epsindab #epsilonindia
