WISE J1517+05 flashes powerful radio bursts every 1.149 hours, making it one of the fastest-spinning ultracool dwarfs detected in radio waves. The latest reports also explore how transit changes can reveal a hidden planet in Kepler-88 and map a possible hotspot on WD 1202-024 B. Other findings track helium in V1298 Tau b’s atmosphere and a warped dust ring around CQ Tau.

Image: Chemical traces of a hidden world: Silicon sulfide hints at a protoplanet in the PDS 66 disk
Astronomers using the ALMA telescope have detected rare molecules of silicon sulfide (SiS) in the dusty disk surrounding the young star PDS 66. This chemical signature is highly unusual because these molecules normally freeze onto dust grains in the cold reaches of a planetary system. The detection of a warm, compact source of SiS gas about 60 astronomical units from the star suggests the presence of a 'protoplanet'—a planet still in the process of forming. This growing world likely has a wa...

Discovery of NGTS-38 b: A rare warm super-Jupiter with a 180-day orbit

Image: Discovery of NGTS-38 b: A rare warm super-Jupiter with a 180-day orbit
Astronomers have discovered a massive gas giant planet, NGTS-38 b, orbiting a bright, metal-rich star similar to our Sun but slightly hotter. This 'warm super-Jupiter' stands out due to its unusually long orbital period of 180.5 days, which is much longer than most planets discovered by the transit method. Unlike the scorched 'hot Jupiters' that orbit their stars in just a few days, NGTS-38 b maintains a relatively cool equilibrium temperatur...

Image: Using intensity interferometry to double-check the size of Red Clump stars
Scientists are testing a specialized method called intensity interferometry to measure the precise physical dimensions of 'Red Clump' stars, such as HD 17652. These aging stars are vital benchmarks used to calculate distances across the universe, including the gap between us and the Large Magellanic Cloud. By analyzing how light interferes at different wavelengths, researchers can map the stellar surface and account for 'limb darkening'—the e...

Image: Probing the magnetic field of a mysterious neutron star in a massive binary system
Using the NuSTAR space telescope, researchers have performed a deep analysis of the X-ray binary 4U 1700-37, a system where a compact object—likely a neutron star—is pulling material from a massive supergiant star HD 153919. By studying the high-energy light emitted as this material falls toward the object, the team looked for 'cyclotron lines,' which act as a direct probe of a star's magnetic strength. While no rhythmic pulses were found, th...

Image: Mystery of the speeding star: Evidence of a violent stellar merger in Taurus
Astronomers have discovered that the unusual star HP Tau/G2 is likely the result of two stars crashing into each other. This 'walkaway' star is currently speeding away from its birthplace alongside another star, KPNO 15, after a complex gravitational dance in a multiple star system caused them to be ejected 5,600 years ago. HP Tau/G2 exhibits strange characteristics for its age, including an oddly large size, fast rotation, and a flattened shape....

Image: New method unlocks secrets of planets that do not cross in front of their stars
Scientists have developed a new technique called the Variable Planetary Infrared Excess (VPIE) method to study exoplanets that never transit (pass in front of) their host stars. By analyzing how the total light from a star system changes as a planet orbits and shows different phases—much like the Moon's phases—this method can isolate the planet's heat signature without needing a complex model of the star itself. Tests using simulated James We...

Image: Searching for hidden companions within the dusty disks of young stars
Using high-precision data from the Hipparcos and Gaia satellites, researchers have analyzed 11 young star systems surrounded by transition disks to find hidden orbiting bodies. The study successfully detected companions in several systems, including confirmed low-mass stars or sub-stellar objects around HD 142527, AB Aurigae, and MWC 758. In other cases, such as TW Hya and HD 100453, the lack of detection allowed scientists to set strict mass...

Image: Extreme heating and atmospheric secrets of the eccentric giant planet HD 80606 b
Astronomers have peeked into the atmosphere of HD 80606 b, one of the most unusual gas giants known due to its incredibly stretched, eccentric orbit. As the planet swings extremely close to its parent star—reaching a distance of just 0.03 AU, much closer than Mercury is to our Sun—it experiences rapid, intense heating. Using high-resolution spectroscopy from the Keck Observatory, researchers looked for signs of chemical changes during this therma...

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 s...

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...
