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: A mysterious pair of sun-like stars reveals secrets of stellar evolution and magnetic cycles
Scientists have conducted a detailed study of HD 81809, a nearby binary system consisting of two stars very similar to our Sun. By using data from the TESS space telescope and ground-based spectroscopy, researchers discovered that these two stars have surprisingly different chemical compositions despite being born together. The primary star is a subgiant that is older and metal-poor, while the secondary star appears to have a composition similar to our Sun, likely due to recently absorbing m...

Image: Two new rocky planets discovered orbiting nearby red dwarf stars
Astronomers using the 'sherlock' pipeline have uncovered two new rocky planets, TOI-237 c and TOI-4336 A c, hidden in data from the TESS space telescope. These planets are roughly 20% larger than Earth and orbit small, cool stars known as M dwarfs. TOI-237 c is a particularly hot world that zips around its star in just 1.74 days, while TOI-4336 A c resides in a complex triple-star system with an orbital period of about 7.6 days. Both planets are ...

Image: Exploring the glowing atmosphere of the ultra-hot Jupiter WASP-33 b
Astronomers have conducted a detailed study of the scorching dayside of WASP-33 b, a giant gas planet much hotter than any planet in our solar system. By analyzing light captured during eclipses, the team discovered a thermal inversion layer where the atmosphere actually gets hotter with altitude, similar to how Earth's stratosphere behaves. The findings reveal a complex chemical cocktail including water vapor, carbon monoxide, and likely tit...

Image: Confirmation of four exotic worlds and a hidden Neptune around nearby red dwarf stars
Astronomers using the high-precision ESPRESSO spectrograph have detailed two fascinating planetary systems orbiting small, cool red dwarf stars. Around the star TOI-4336 A, they found a rocky super-Earth and a gaseous sub-Neptune, the latter of which is a prime candidate for future atmospheric study. Meanwhile, the star TOI-4342 hosts two sub-Neptunes of nearly identical size but different densities, along with a newly detected third planet—a...

Image: A third super-Earth discovered orbiting the nearby star HD 176986
Astronomers have discovered a new planet in the HD 176986 planetary system, located about 91 light-years away from our Sun. Using high-precision instruments to filter out stellar activity, researchers identified a third world joining the two previously known super-Earths. This new planet, HD 176986 d, orbits its star every 61 days and is nearly seven times more massive than Earth. All three planets in this system are classified as super-Earth...

Image: Record-breaking supersonic winds discovered on the ultra-hot giant planet KELT-9 b
Astronomers using the Keck Planet Finder have detected the most extreme atmospheric winds ever recorded on a gas giant outside our solar system. By observing the ultra-hot Jupiter KELT-9 b as it orbits its star, researchers measured supersonic winds reaching speeds of nearly 12 kilometers per second—over 40,000 kilometers per hour. These massive winds carry heat from the permanent dayside to the nightside, revealing a complex global climate. ...

Image: Oxygen-rich atmospheres may develop much faster on planets orbiting red dwarfs than on Earth
A new study focusing on the Earth-like exoplanet TRAPPIST-1e suggests that the transition to an oxygen-rich atmosphere, known as the Great Oxidation Event, could occur up to a billion years sooner than it did on our own planet. While Earth's atmosphere took hundreds of millions of years to accumulate oxygen after the appearance of life, the unique light from M-dwarf stars promotes more efficient ozone formation. This process lowers the barrie...

Image: JWST Discovers a Potential Giant Planet Orbiting a Dead Star
Using the James Webb Space Telescope, astronomers have discovered a significant infrared glow around white dwarf star WD 0644+025, an unusually heavy white dwarf located within 25 parsecs of Earth. This excess heat suggests the presence of a giant planet, roughly seven times the mass of Jupiter, orbiting the remains of this dead star. While white dwarfs are the final stage of stars like our Sun, this particular star is unique because it shows...

Image: Discovery of a New Earth-Sized Neighbor: A Potential Twin of Our Home Planet Found Orbiting a Sun-Like Star
Astronomers have discovered a fascinating planet candidate, named HD 137010 b, which bears a striking resemblance to Earth. Located around a bright star similar to our Sun, this world is almost exactly the same size as Earth and orbits its star every 355 days—a year nearly identical to our own. Because it sits at the outer edge of the 'habitable zone,' it receives just enough light and heat that it could potentially host liquid water. This di...

Astronomers have discovered a new giant planet named TOI-6692b, which is similar to Jupiter but follows a much more elongated, eccentric path around its star. While Earth takes a year to orbit the Sun in a nearly circular path, this massive world completes its orbit in 130 days, swinging in and out due to its oval-shaped trajectory. Initially spotted by a single shadow it cast while passing in front of its star, its existence was confirmed usi...
