[NASA] Astronomers using NASA’s James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems […]
Gas Giants
The GAPS Programme with HARPS-N at TNG LXXVII. Occurrence Rates Of Small Close-in Planets In The Presence Of Cold Jupiters
[astro-ph.EP] Context. The architecture of our Solar System, with inner small planets (ISPs) and outer giants, may or may not be common. Understanding whether a correlation exists between ISPs and […]
Photochemical Production of CS2 in Temperate-to-Warm Gas Giant Exoplanet Atmospheres
[astro-ph.EP] Sulfur chemistry has emerged as an important probe of exoplanet atmospheres in the JWST era, although observational constraints have thus far been largely limited to SO2 and H2S in […]
C,N,O,S, And Photochemistry In A Temperate Giant Planet Orbiting A Late M Dwarf
[astro-ph.EP] We report the JWST NIRSpec/PRISM transit spectrum of TOI-6894b, an exceptional 420 K sub-Saturn that is the only known giant planet transiting a late M dwarf. Remarkably, both the […]
TESS Reveals The Puffiest Exoplanets Ever Found
Data from NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has revealed two new “super-puff” planets, giant worlds so light that their density is comparable to cotton candy. Scientists calculate that […]
Direct Imaging Discovery of Giant Exoplanet β Pictoris d: A Decade-Long Game of Hide-and-Seek
We report the direct imaging discovery of a third exoplanet in the β Pictoris system. We detect β Pictoris d in non-coronagraphic observations obtained with VLT/ERIS as well as multi-epoch […]
First Ever Live Observation Of The Rotation Of A Planetary Nursery
The rotation of a protoplanetary disc (a disc where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains […]
The Pan-Pacific Planet Search — IX. A Menagerie Of Companions Orbiting Evolved Stars
We present resolutions as to the nature of six speculative candidate companions proposed in the final data release of the Pan-Pacific Planet Search, a 6-year radial-velocity survey of 164 southern […]
Strange Winds Reveal Strongest Hints Yet Of Magnetic Activity In Exoplanets
By measuring the strength of the invisible magnetic fields of seven ultra-hot Jupiters, astronomers have taken a major step toward understanding planets beyond our Solar System. A new study published […]
NASA’s Roman Mission Preps to Unveil New Populations of Faraway Worlds
NASA’s Nancy Grace Roman Space Telescope is poised to make a major leap in the hunt for worlds outside our solar system, known as exoplanets. Scientists expect the mission to […]
