The changing light of blue supergiant HD 74371 points to a dramatic turn in its life: the star appears to be moving blueward after a red-supergiant phase. Other fresh findings reveal helium escaping from an exoplanet, infrared rhythms on WASP 121, shifting radio and X-ray emissions from young V1298 Tauri, and clouds across WASP-43 b.

Image: JWST reveals low-metallicity atmosphere and stellar effects for giant planet HATS-75 b
HATS-75 b is a giant planet orbiting a red dwarf star, recently studied as part of a program using the James Webb Space Telescope. Scientists observed three transits of the planet, where it passed in front of its star, to analyze its atmosphere. The planet's spectrum showed a deeper transit at shorter wavelengths, which can be caused by hazes in the atmosphere or by features on the star's surface, such as starspots and bright regions. By comparing different models, researchers found that the ...

Image: Turbulence measured in the outer disk of HL Tauri reveals strong nonthermal motions
HL Tauri is a young star surrounded by a protoplanetary disk with rings and gaps, where planets may be forming. Understanding turbulence in such disks is important because it affects how material moves and how planets grow. Until now, the strength of turbulence in the outer parts of these disks was not well known, especially in systems still gathering gas from their surroundings. Researchers used ALMA telescope data to study the disk around HL...

Image: JWST eclipse observations probe atmosphere and surface of rocky planet Gliese 3473 b
Gliese 3473 b (GJ 3473 b) is a rocky exoplanet orbiting close to its star, making it highly exposed to intense starlight. Scientists used the James Webb Space Telescope to observe the planet as it passed behind its star, a phenomenon called a secondary eclipse. These observations help reveal whether the planet has an atmosphere or if it is a bare rock, a key question for understanding how such worlds evolve under strong stellar radiation. The ...

Image: Star-disk interaction and accretion in the young T-Tauri star DO Tauri
DO Tau is a young star surrounded by a disk of gas and dust, where planets may eventually form. This system is a T Tauri star, a type of young, Sun-like star still gathering material from its surroundings. By combining high-resolution infrared spectra and advanced imaging, researchers have studied the region where the star and its disk interact, revealing new details about how material moves from the disk onto the star. The team used two main ...

Image: Mega-Earth GJ 523b: a young, ultra-dense planet with a tilted orbit
GJ 523 b (BD+39 2675 b) is a recently confirmed planet orbiting a mid-type orange dwarf star called Gliese 523. This planet is unusually massive for its size, earning it the classification of a mega-Earth. At just 170 million years old, GJ 523b is much younger than most known exoplanets, and it orbits its star every 17.75 days. Its high density suggests it has very little gas, despite its large mass, which is rare for planets of this size....

Image: Hot Jupiter TOI-7169 b orbits one of the oldest, most metal-poor stars
TOI-7169 b is a giant planet, known as a hot Jupiter, that orbits a star with very low metal content. Most planets are found around stars rich in elements heavier than hydrogen and helium, but TOI-7169 b challenges this trend by orbiting a metal-poor star. This discovery helps scientists understand how planets can form in environments with fewer heavy elements. The planet was detected using data from the TESS space telescope and ground-based o...

Image: Hazes and chemistry shape the atmosphere of K2-18 b, a sub-Neptune exoplanet
K2-18 b is a temperate sub-Neptune planet orbiting a red dwarf star, making it a key target for understanding atmospheres beyond our Solar System. Recent observations with the James Webb Space Telescope have provided new insights into its atmospheric composition and structure, helping to bridge the gap between planets like Neptune and the more commonly studied hot-Jupiters. Researchers used a detailed computer model to study K2-18 b's atmosphe...

Image: Spectroscopy reveals atmospheric differences in hot Jupiters and Neptunes near the Neptune desert
Hot Jupiters and ultra-hot Jupiters are gas giant planets that orbit very close to their stars, making them excellent targets for atmospheric studies. This research examined five such planets—WASP-50b, WASP-117b, WASP-156b, WASP-167b, and WASP-173Ab—using high-resolution spectroscopy to search for atmospheric signals. These planets are located near the so-called Neptune desert, a region where Neptune-sized planets are rare at short orbital period...

Image: Second protoplanet found in WISPIT 2 system forming in a disk of material orbiting the young star
WISPIT 2 is a young star surrounded by a multi-ringed disk, already known to host a giant planet, WISPIT 2b, in a wide gap. This study confirms the existence of a second planet, WISPIT 2c, using new imaging and spectroscopic data from the VLT/SPHERE and VLTI/GRAVITY instruments. The observations reveal a point-like source close to the star, with a K-band spectrum showing features typical of a young giant planet, including carbon monoxide absorpti...

Image: SPHEREx reveals a molecular hydrogen shell around nova GK Persei
GK Persei, a nova that erupted in 1901, continues to surprise astronomers more than a century later. Using data from the SPHEREx space telescope, researchers discovered a large, bipolar shell of molecular hydrogen surrounding the nova. This shell, measuring 18 by 10 arcminutes, matches the shape and location of the known H-alpha nebulosity around GK Persei, which was previously thought to be an ancient planetary nebula. The hydrogen shell is m...
