A planet’s escaping helium, a star’s hidden infrared rhythms, and a possible distant world in the WISPIT 2 system reveal how much we can learn by watching light across the spectrum. New observations also trace the changing radio and X-ray activity of young V1298 Tauri, while detailed models map cloudy and clear regions across the hot Jupiter WASP-43 b.

Image: Compact planetary system TOI-1533 hosts two unique super-Neptune planets
The planetary system TOI-1533 consists of two planets orbiting an active orange dwarf star. Located in a compact arrangement, this system features an inner sub-Neptune planet and an outer, larger hot giant planet. Such systems, where a large gas-rich planet is accompanied by a smaller companion, are rare and provide insight into how planetary systems migrate and evolve over time. The research reveals that both planets transit, or pass in front of, their host star. The inner planet, TOI-1533 b...

Image: Atmospheric composition of temperate exo-Neptune TOI-1231 b revealed by JWST
The temperate exo-Neptune TOI-1231 b serves as a vital benchmark for understanding planets smaller than Neptune. Because of its density, the planet is known to possess a deep, hydrogen-rich atmosphere. This study provides the first near-infrared transmission spectrum—a technique that analyzes how starlight filters through a planet's atmosphere—to determine its chemical makeup, offering a reference for similar worlds. Researchers identified a s...

Image: Orbital architecture and spin-orbit alignment of the TOI-2134 planetary system
The TOI-2134 planetary system contains two confirmed planets orbiting their host star. The inner planet is a mini-Neptune, a gas-rich world smaller than Neptune, while the outer planet is a temperate sub-Saturn. By combining new observations from the TESS space telescope with extensive ground-based velocity measurements, the composition and orbital paths of these planets have been precisely determined, revealing a complex system architecture. ...

Image: Observations of PDS 70 reveal new dust clumps and potential third planet
The young star PDS 70 is known to host two confirmed protoplanets within its disk of gas and dust. Recent observations have identified two elongated dust features near the star, which may indicate the presence of a previously unknown third planet or complex structures within the inner disk. These features share the same orbit, with one leading the other by approximately 120 degrees, suggesting they could be dust trapped by the gravity of an unsee...

Image: Orbital analysis of Kepler-451 reveals evidence for a circumbinary planet
Kepler-451 is a binary star system hosting a planet that orbits both stars, known as a circumbinary planet. By analyzing the timing of eclipses between the two stars from 2004 to 2024, the study investigated variations in the orbital period. These variations, which appear as shifts in the expected timing of eclipses, provide clues about gravitational influences from additional objects in the system or internal changes within the stars themselves....

Image: Stellar passage of HD 7977 likely triggered a comet shower in our solar system
Long-period comets, which take thousands of years to orbit the Sun, are traditionally thought to be nudged toward the inner solar system by the gravitational pull of the Milky Way's disk. New evidence suggests that the star HD 7977 may have passed close to our solar system 2.5 million years ago, creating a "comet shower" that continues to influence the number of comets we observe today. The research compared computer simulations of long-period...

Image: Glossy silicate clouds discovered on the dayside of ultra-hot planet LTT 9779 b
LTT 9779 b is an ultra-hot Neptune-sized planet orbiting in a region of space known as the Neptunian desert, where such worlds are typically not found. Recent observations have provided the first clear evidence of clouds on the dayside of this planet. These clouds, made of silicate—a common mineral found in rocks—act as a highly reflective layer, explaining why the planet appears so bright when viewed from space. The analysis confirms that the...

Image: New model measures global atmospheric wind speeds on the planet WASP-76 b
Atmospheric circulation on ultra-hot Jupiters—massive gas planets that orbit very close to their host stars—can be studied by observing how light emitted by the planet shifts in frequency. A new computational method has been developed to translate these subtle light shifts into precise measurements of wind speeds across the planet’s surface. This approach provides a clearer picture of how gases move on extreme worlds like WASP-76b. To test thi...

Image: Circumstellar disks observed around five massive Herbig Be stars
Herbig Be stars are young, massive stars that are still in the early stages of their development. Understanding whether these stars host disks of dust and gas is essential to determine if they can form giant planets. A recent survey of 24 of these massive young stellar objects, located within 3,000 light-years of Earth, has provided new insights into the existence and nature of these planet-forming environments. The research identified 1.3-mil...

Image: Transit of giant exoplanet HIP 41378 f shows significant timing variations
The giant exoplanet HIP 41378 f, which orbits its host star every 542 days, has been observed during a 19-hour transit event. This rare long-period planet, roughly 9.5 times the radius of Earth, provides researchers with a look into planetary systems that are difficult to study. By capturing this transit, the timing of the planet's passage was measured, confirming significant deviations from expected patterns known as transit timing variations. ...
