Uranus and Neptune May Be Rocky Worlds Not Ice Giants, New Research Shows

A new analysis challenges decades-old assumptions about Uranus and Neptune, revealing that both planets may contain far more rock than icy materials. These findings help explain their strange magnetic fields and show that traditional "ice giant" models may be incomplete. Scientists say only dedicated future missions can uncover the true interior makeup of these distan...

Neutrino Detectors May Unlock the Search for Light Dark Matter, Physicists Say

Physicists now believe that massive neutrino detectors—built to observe rare solar and cosmic particles—could also detect extremely light dark matter that traditional experiments miss. By monitoring subtle annual variations in their background signals, observatories like JUNO and Borexino may open a new frontier in uncovering the universe’s most elusive and abun...
