Weighing potentially habitable planets around Sun-like stars remains surprisingly difficult: a methods test found that precise measurements often require planets weighing about 8 to 10 Earth masses. The latest reports also explore brilliant radio bursts from a rapidly spinning brown dwarf, a possible hotspot on another brown dwarf, and how transit changes can expose a planet that never crosses its star.

Simulations suggest that rare Neptune-like planets orbiting close to their stars can form through a series of collisions between smaller planets

Image: Three Jupiter-like planets confirmed orbiting close to Sun-like stars
One of the stars, TOI-4914 b, is more inflated than what is supported by current theoretical models. Warm Jupiter TOI 4914 b has about 70 % of Jupiter's mass, but its radius is 15 % bigger. That gives it about half of Jupiter's density....

Image: Rare planet discovered orbiting near the Neptunian desert of a star TOI-3568
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....

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....

Image: By comparing images of Beta Pictoris disk taken over years, astronomers found evidence of potential changes in its brightness
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....
