Stellar Brief: 20. 10. 2026
Today’s standout finding changes the story of PDS 70: the young star is estimated to be 12 to 16 million years old, about three times older than previously thought. Alpha Centauri was the leading Stellarcatalog search query, with 1,537 impressions on October 19.

Estrellas | Exoplanetas | TESS | Enana naranjThe 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...

2. 7. 2026Estrellas | Exoplanetas | Telescopio espacial James Webb | Atmósferas planetariThe 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...
Read article 2. 7. 2026Estrellas | ExoplaneThe 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.

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...

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....
Read article 25. 6. 2026EstreLong-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...

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...
Read article 24. 6. 2026Estrellas | Exoplanetas | Júpiter calienteAtmospheric 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...

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...
Read article 24. 6. 2026Estrellas | ExoplaneThe 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.
