Stars | Exoplanets | Super-EarthThe internal makeup of the super-Earth Gliese 486b has been estimated by analyzing the chemical properties of its host star. Because rocky planets typically inherit their chemical composition from the materials that formed their parent stars, understanding the composition of a star provides a window into the building blocks of its orbiting planets. This research provides a new framework that links stellar chemical data to the internal structure and mineralogy of distant rocky worlds.

23. 8. 2026Stars | Exoplanets | James Webb Space TelescopeThe Trappist-1 system, a small star orbited by seven Earth-sized planets, has been a major target for the James Webb Space Telescope. While the inner planets have been studied directly, the potential to detect thermal emission—the heat energy radiated by a planet—from the outer planets remains a significant challenge due to interference from the host star itself.
This analysis compiled existing observations from five separate projects to see i...
Read article 23. 8. 2026Stars | Exoplanets | James Webb Space TelescopeRecent observations of the temperate planet LHS 1140 b have provided new insights into its atmosphere. While previous data suggested the presence of helium escaping from the planet, detailed analysis of four planetary transits—the period when a planet passes in front of its star—reveals no consistent evidence of such activity, indicating that earlier detections may have been influenced by stellar changes or instrumental factors.

Read article 23. 8. 2026Stars | Exoplanets | James Webb Space TelescopeThe warm Saturn-sized exoplanet WASP-69 b exhibits significant atmospheric differences between its morning and evening sides. New observations reveal an asymmetric distribution of aerosols—tiny particles suspended in the atmosphere—which create distinct cloud conditions across the planet. This discovery helps explain how planets at temperatures near 1,000 Kelvin manage the cycle of cloud formation and evaporation as material travels around the gl...
Read article 13. 8. 2026Stars | ExoplaneThe thermal characteristics of 55 Cancri e, an ultra-short period rocky planet, are better understood by accounting for the planet’s three-dimensional geometry and its rotation. By calculating how sunlight hits the planet at various angles throughout its day, it is possible to model the temperature distribution across its surface more accurately. This approach clarifies why the planet exhibits a specific thermal imprint observed by telescope meas...
Read article 13. 8. 2026Stars | Exoplanets | Planetary atmosphereAF Lep b is a young gas giant planet with a mass roughly three to four times that of Jupiter, orbiting its host star at a distance of approximately 9 astronomical units. Recent observations using the James Webb Space Telescope have allowed for a detailed look at the chemical composition of its atmosphere, providing new insights into how this massive planet formed and grew during the early stages of its solar system.
The research team analyzed ...

By studying the dust disks surrounding the planets PDS 70 c and SR 12 c, it is clear that these distant worlds share significant similarities with the development of Jupiter and Saturn. These observations help explain how gas and dust accumulate to form planets and smaller satellites in the early stages of a star system's life.
The pl...
Read article 13. 8. 2026Stars | Exoplanets | TESS | Sun-like starA multi-planet system has been identified orbiting TOI-3850, a G0 dwarf star similar in metallicity to our Sun. The system contains two warm planets—gas-rich worlds that orbit closer to their star than Jupiter, but further than the extremely hot planets commonly found in close proximity to their hosts. These planets are currently situated near a gravitational configuration known as a 2:1 mean motion resonance, where the outer planet completes one...
Read article 13. 8. 2026Stars | ExoplaneRecent observations have analyzed the environments around three stars - DMPP-7, HD 67200, and HD 2134 — to search for evidence of orbiting planets. By studying radial velocity, which measures the tiny wobbles in a star’s position caused by the gravitational tug of an orbiting planet, the project examined these systems to distinguish between genuine planetary signals and the natural activity of the stars themselves.
The researchers used a Bayes...
Read article 10. 8. 2026Stars | Exoplanets | Planet formatioProtoplanetary disks are vast, swirling clouds of gas and dust surrounding young stars that eventually coalesce to form planets. A new method has been developed to analyze the physical properties of these disks by examining how their dust rings appear when viewed at an angle. By studying these shapes, researchers can determine the intrinsic width, thickness, and light-blocking capacity, known as optical depth, of the dust material within the disk...
