A planet’s helium atmosphere streams ahead of its orbit, while infrared observations reveal the hidden rhythms of its star. New work also shows how neutron-star tilt can reshape X-ray light, traces the past of massive blue supergiants, and maps cloudy and clear zones on the hot Jupiter WASP-43 b.

Image: ALMA tomography reveals hidden planets in protoplanetary disks
The exoALMA Large Program has uncovered many detailed structures in the dust and gas of protoplanetary disks, where planets are forming around young stars. By using a technique called tomography—studying how molecular lines change at different locations and velocities—astronomers can now detect the presence of planets hidden within these disks. The study shows that even with a few hours of ALMA telescope time, it is possible to spot the signatures of planets more massive than about one-thousa...

Image: JWST observations and new models reveal how silicate clouds form in exoplanet atmospheres
The James Webb Space Telescope (JWST) has detected silicate clouds in the atmospheres of several exoplanets, providing new insights into how clouds form in extreme environments. While simple models can fit these observations, they do not always match the results from more detailed microphysical models. To address this, researchers developed Nimbus, a fast model that simulates cloud formation based on physical processes, and used it alongside Virg...

Image: Ortho-para chemistry of formaldehyde reveals new clues in TW Hya’s protoplanetary disk
The protoplanetary disk around TW Hya is a key site for studying how planets form and what materials they inherit. Understanding the distribution of chemical elements and molecules in such disks helps scientists learn about the building blocks of planets, especially those that could be habitable. One important molecule is formaldehyde (H2CO), which exists in two forms: ortho and para, depending on the spins of its hydrogen atoms. Recent ALMA o...

Image: Combining radial velocity and astrometry reveals new cold giant planets around 5 stars
Long-period giant planets, or cold Jupiters, play a key role in shaping planetary systems, but they are difficult to detect because they orbit far from their stars. Traditional methods like radial velocity and transit surveys have limited sensitivity at these distances. By combining long-term radial velocity data with precise astrometry from the Hipparcos and Gaia missions, astronomers can now better detect and measure these distant worlds. In...

Image: JWST data reveal silicate clouds and high metallicity in WASP-107 b’s atmosphere
WASP-107 b is a warm gas giant planet that has been studied in detail using the James Webb Space Telescope (JWST). Its atmosphere shows a unique feature at 8–10 micrometers, thought to be caused by silicate clouds. Scientists aimed to explain the planet’s full spectrum, from near-infrared to mid-infrared, using a physically realistic model of cloud formation and temperature. The research team used a model that links how clouds form with how he...

Image: Transit timing variations in HD 332231 b hint at a hidden planetary companion
HD 332231 b is a warm sub-Saturn exoplanet that orbits close to its host star. Astronomers studied the timing of its transits—when the planet passes in front of the star—and found that these events do not occur at perfectly regular intervals. Instead, the transit times show a repeating pattern, known as transit timing variations (TTVs), which can reveal the presence of other planets in the system. Using precise data from the TESS mission and g...

Image: Earth-sized planet found orbiting a nearby red dwarf LP 466-156 (TOI-4616)
TOI-4616 b is an Earth-sized exoplanet that orbits a nearby red dwarf star, just 28 parsecs from Earth. Red dwarfs are small, cool stars, and their low brightness makes it easier to spot planets passing in front of them. This planet was discovered and confirmed using data from NASA’s TESS mission, along with ground-based telescopes and detailed follow-up observations. The host star, classified as an M4 dwarf, is about 19% the size and mass of ...

Image: Long wavelength observations of Epsilon Indi A b suggest a metal rich atmosphere and the presence of clouds
The nearby star Epsilon Indi hosts a cold gas giant planet, Epsilon Indi A b, located just under 12 light years from Earth. Using the James Webb Space Telescope (JWST), astronomers captured the longest-wavelength image ever taken of an exoplanet, extending up to 25 micrometers. By combining these new images with decades of radial velocity and astrometric data, the team precisely determined the planet’s orbit and mass. The planet’s light was me...

Image: ALMA images reveal possible dust-trapping vortex in HD 34282’s protoplanetary disk
HD 34282 is a young star surrounded by a disk of gas and dust, where planets may be forming. Using the ALMA telescope, astronomers captured detailed images of this disk at several wavelengths, revealing a bright arc and a complex pattern of rings and gaps. These features help scientists understand how dust and gas behave in planet-forming environments. The observations show that the bright arc has a lower spectral index than the surrounding ri...

Image: Simulations reveal two families of exocomets in the Beta Pictoris system
The Beta Pictoris system is famous for its young star, two giant planets, and a large disk of dust and gas. Recent studies have found many comet-like bodies orbiting the star (exocomets). To understand how these exocomets form and evolve, researchers simulated the system with over 100,000 test particles, tracking their paths for 25 million years. The simulations show that most material is quickly cleared out by the planets, except for two main...
