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: Cold Jupiters often hide hot super-Earths in their inner orbits
A statistical analysis of 132 planetary systems reveals a strong architectural link between giant outer planets and smaller inner worlds. Researchers found that stars hosting a 'cold Jupiter'—a gas giant orbiting far from its sun—are significantly more likely to also host 'hot super-Earths' in close-in orbits. The study suggests that approximately 87% of these giant planet systems also contain at least one smaller rocky planet closer to the star. This discovery, supported by data from the TE...

Gas-depleted planet formation revealed in the LHS 1903 planetary system

Image: Gas-depleted planet formation revealed in the LHS 1903 planetary system
New analysis of the four-planet system surrounding the red dwarf LHS 1903 provides a rare look at how planets form when gas is scarce. While the inner planets possess varying atmospheric thicknesses, the outermost world, LHS 1903 e, stands out because it completely lacks a gaseous envelope despite its distant orbit. This suggests that the planet likely formed from material already depleted of gas, rather than losing its atmosphere later in li...

Image: How sub-Neptunes turn into water worlds by losing their hydrogen
A new study using the BOREAS model reveals how sub-Neptune planets can transform their atmospheres over hundreds of millions of years. By analyzing how different elements escape into space, researchers found that lighter hydrogen is often stripped away while heavier oxygen remains trapped. This process, known as chemical fractionation, can gradually turn a gas-poor envelope into a water-rich atmosphere. The findings suggest that planets like GJ 9...

Image: Secrets of the cold giant 51 Eridani b revealed through high-resolution spectroscopy
Using the advanced HiRISE instrument at the Very Large Telescope, astronomers have performed a detailed analysis of 51 Eridani b, one of the faintest directly imaged planets ever found. By measuring the planet's radial velocity across four different time periods, the team successfully mapped its full 3D orbit, breaking previous uncertainties. They discovered that the planet follows a highly stretched, or eccentric, path rather than a circular...

Image: A second giant planet discovered orbiting the star HD 164604
Astronomers have discovered a new massive giant planet, HD 164604 c, which takes about 15 years to orbit its parent star. By combining data from ground-based telescopes and space missions like Gaia, researchers also refined our understanding of a previously known inner planet in the same system. The study reveals a fascinating orbital dance: the two planets might be moving in opposite directions (a retrograde orbit), suggesting a violent past...

Image: JWST peers into the freezing atmosphere of the distant giant planet L 97-3 b (WD 0806 b)
Using the James Webb Space Telescope (JWST), astronomers have conducted a detailed analysis of WD0806 b, one of the coldest planets ever photographed outside our Solar System. Orbiting a white dwarf at a massive distance—about 60 times further than Pluto is from our Sun—this gas giant has temperatures of only 350 K (roughly 77°C). The study identified a cocktail of chemicals in its atmosphere, including water, methane, and carbon dioxide. For...

Image: Confirmation of a second closest habitable zone super-Earth around nearby star Lacaille 9352 (GJ 887)
Astronomers have confirmed a complex multiplanet system orbiting Lacaille 9352 (also Gliese 887, HD 217987) - a bright red dwarf star only 11 light years away. Using high-precision instruments, the team identified two new worlds: a small planet roughly the mass of Earth with a very short 4-day orbit, and a larger 'super-Earth' located within the star's habitable zone, where temperatures could allow for liquid water. This super-Earth, which ta...

Image: Tracing the chemical ingredients of future planets in the AB Aurigae disk
By studying the swirling disk of gas and dust around the star AB Aur, astronomers are gaining a clearer picture of the raw materials available for building new worlds. Using the NOEMA radio interferometer, researchers measured the ratio of carbon to oxygen—a key indicator of a planet's future atmosphere—by observing specific molecules like carbon monosulfide and sulfur monoxide. The data suggests that this 'planetary nursery' is carbon-rich b...

Image: The rejuvenated star V658 Carinae: A fast-spinning survivor of cosmic mass transfer
Scientists have uncovered the unusual characteristics of V658 Car, a binary star system that has recently undergone a dramatic 'makeover' through mass transfer. The system consists of a rapidly spinning Be-type star and a smaller, hot companion. The main star is spinning at a staggering 336 km/s—fast enough to fling material into a massive glowing disk that stretches 42 times the radius of our Sun. Surprisingly, the study found that this star...

Image: Mapping the energetic connection between radio and X-ray emission in Milky Way stars
A new study exploring the heart of our Galaxy has identified 137 stars that shine in both radio waves and X-rays, providing a clearer picture of stellar magnetic activity. By combining data from the MeerKAT radio telescope and the eROSITA X-ray satellite, researchers tested the famous Güdel-Benz relation, which usually links a star's heat-driven X-rays to its high-energy radio flares. The findings reveal that many stars in the Galactic plane ...
