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: 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 titanium oxide, all wrapped in a high-metallicity env...

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...

Researchers have compiled detailed spectral energy distributions for 20 stars that hosted exoplanets studied by the James Webb Space Telescope. By measuring the X-ray and ultraviolet light emitted by these stars, the team highlights how intense radiation impacts the atmospheres of orbiting planets. This data includes vital information on stars like Tau Ceti, helping experts better understand the potential for atmospheric loss on these worlds....
