Are mega-Earths, massive rocky planets without thick gas envelopes, actually real?

A new study suggests that stellar activity may be making some planets appear far heavier than they are. By analyzing 333 planets, researchers found that eight unusually dense worlds orbit magnetically active stars, raising questions about how reliably astronomers measure planetary masses. Could some of the universe’s strangest planets be measurement illusions?

New Hubble Space Telescope observations are challenging scientists’ understanding of how the early universe became transparent. Surprisingly, galaxies with the fastest winds appear to trap more radiation rather than release it.

The findings suggest that young stars may have helped clear the primordial hydrogen fog before supernova explosions reshaped these galaxies. Could this change what we know about the universe’s earliest evolution?
