A star’s hidden vibrations, a planet’s escaping helium, and worlds wrapped in shifting clouds reveal how much can be learned from changing light. Recent observations trace WASP 121’s surface motions in infrared for the first time, map the uneven clouds of WASP-43 b, and catch helium streaming ahead of TOI-3884 b. Light patterns also place the massive star HD 74371 on a return journey toward bluer colors after its red supergiant phase, while search interest spans Proxima Centauri b, Alpha Centauri, and many other stellar neighbors.

Image: Revised measurements for planet Gliese 367 b show it is not pure iron
Gliese 367 b is an ultra-short-period planet that orbits its host, a Red dwarf star, in just 7.7 hours. Because it is located only about 9 parsecs (roughly 29 light-years) from Earth, it has been a target for intense study. Previous research suggested the planet possessed an extremely high density, implying it might be composed almost entirely of solid iron, a finding that challenged standard models of how planets form. New, high-precision measurements have now updated the understanding of this ...

Image: Atmospheric composition and clouds detected on the planetary companion Gliese 504 b
Gliese 504 b is a planetary-mass companion orbiting a distant star. Previously too faint for detailed study from the ground, this object has now been analyzed using the James Webb Space Telescope. The data reveal a complex atmosphere filled with various molecules and evidence of salt clouds, providing a rare look at the chemistry of a cool, directly imaged world. Spectroscopic analysis—the process of breaking down light into a spectrum to iden...

Atmospheric temperature and chemical patterns measured in the ultra-hot Jupiter WASP-121 b

Image: Atmospheric temperature and chemical patterns measured in the ultra-hot Jupiter WASP-121 b
WASP-121 b is an ultra-hot Jupiter, a gas giant planet orbiting extremely close to its host star. Because it is tidally locked, meaning the same side always faces its star, the planet experiences extreme temperature differences across its surface. New observations show that the planet's rotation creates detectable changes in the light it absorbs as it passes in front of its star, revealing uneven temperature and chemical distributions. Data fr...

Image: Eccentric warm Jupiters TOI-2147 b and TOI-6019 b characterized by researchers
Warm Jupiters are gas giant planets with orbital periods between 10 and 200 days. Two such planets, TOI-2147 b and TOI-6019 b, have been identified and characterized. These planets exhibit high orbital eccentricity, meaning their paths around their host stars are more oval-shaped than circular. Their characteristics suggest they migrated to their current positions through processes involving high-eccentricity interactions. The planetary nature...

Image: Infant planet TOI-837 b shows a mildly misaligned orbit around its star
TOI-837 b is a young, Saturn-sized planet located in the IC 2602 cluster, which is only 35 million years old. By studying the spin-orbit obliquity—the angle between the axis of the planet's orbit and the axis of the host star's rotation—researchers can determine how planets migrated to their current positions. This planet is the first younger than 100 million years observed to have a measurable misalignment, providing a rare look at planetary evo...

Image: Thick carbon dioxide atmosphere confirmed for exoplanet 55 Cancri e
The exoplanet 55 Cancri e is a hot, rocky world with a complex atmosphere that has been the subject of recent study. New research using advanced three-dimensional climate models shows that the planet likely possesses a thick, carbon dioxide-rich atmosphere. This conclusion relies on simulations that account for heat distribution across the planet, providing a more detailed look than previous one-dimensional models allowed. The findings indicat...

Image: Statistical analysis confirms TOI-7701 b as a sub-Saturn planet orbiting a subgiant star
TOI-7701 b (TOI-7701.01) is a transiting object orbiting a bright F-type subgiant star. Initially identified as a candidate in a machine-learning survey, its true nature as a planet had remained uncertain until now. New statistical analysis has confirmed this object as a sub-Saturn, placing it at the critical boundary between giant planets and low-mass brown dwarfs, which are objects larger than planets but smaller than stars. The confirmation...

Image: Carbon isotope ratio measured in the atmosphere of planet Beta Pictoris b
Beta Pictoris b is a young, giant planet located in a star system where astronomers can directly image its atmosphere. By studying the specific chemical makeup of this world, researchers can learn how it formed and how its composition compares to the raw materials found in the gas cloud that birthed the system. This study provides a detailed chemical profile of the planet, focusing on carbon isotopes and its overall atmospheric makeup. The pla...

Image: Atmosphere of the rocky exoplanet Gliese 486 b studied with infrared observations
Gliese 486 b is a rocky exoplanet orbiting a Red dwarf star at a distance of about 26 light-years from the Solar System. Because it orbits very close to its host star, the planet is extremely hot, with surface temperatures reaching approximately 700 Kelvin. Observations from the James Webb Space Telescope were used to examine the light from the star as the planet passed in front of it to search for an atmosphere. The research indicates that th...

Image: Transit depth variations in young multi-planetary system HIP 67522 reveal stellar surface activity
The HIP 67522 system, at approximately 17 million years old, is one of the youngest multi-planetary systems ever observed. This Sun-like star, located within the Scorpius-Centaurus OB association, hosts two Saturn-sized planets locked in a near 2:1 orbital resonance, meaning that for every orbit the outer planet completes, the inner planet completes roughly two. Scientists have conducted an analysis of photometric transit data—where the dimming o...
