Today's spotlight falls on the fascinating white dwarf WD J1330, a star currently drawing significant attention from researchers and enthusiasts alike. While we often think of white dwarfs as plain, new research highlights their remarkable visual diversity, proving these dense stellar remnants can shimmer in vibrant hues from yellow to purple depending on their unique chemical signatures.

StarA 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 barrier for full atmospheric oxidation, potentially allo...

28. 1. 2026Stars | Exoplanets | White dwarfUsing 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...
Read article 28. 1. 2026Astronomers 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...
Read article 27. 1. 2026StarAstronomers 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...

Read article 4. 1. 2026Stars | Exoplanets | Sun-like stars | James Webb Space TelescopeResearchers 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....
