The results suggest that sulfur in this disk may have a different isotopic composition than in our solar system....

It is a hot planet, bigger than Neptune with one of the highest luminosities in extreme ultraviolet for planets of this size. TOI-3568 b is 50% heavier than Neptune and its radius is 40% bigger. With an orbit lasting 4.4 days, it sits just outside the Neptunian desert, where the star evaporates the atmospheres of planets smaller than Jupiter and where only a few planets of this size have been found....

TOI-5688 is a binary star almost 750 light years away from the Sun. The newly discovered planet orbits the primary star every 2.9 days and has radius 10 times bigger than Earth which is similar to Saturn....

This is the most precise measurement yet of terrestrial exoplanet's thermal emission with JWST. Gliese 486 is a red dwarf only 26 light years from the Sun. The exoplanet Gliese 486 b orbits the star once every 36 hours. It is bigger, denser and hotter than Earth....

This could be caused by collisions between objects in the disk. While no definitive evidence of such collisions has been found yet, the study provides valuable insights into the dynamics of planetary systems and the processes that shape them....

If this is the case, the lava circulation has a minimal impact on the planet's temperature distribution....

New observations also suggest that the planet's atmosphere might be escaping into space....

Its mass suggests that it almost reaches the hydrogen-burning limit, which would make it a star....

These eruptions are much stronger than those seen on our Sun. The findings challenge the previous understanding that strong magnetic fields near the poles would prevent such eruptions....
