Ion Recycling Illuminates the Heaviest Elements
Introduction: Pushing the Boundaries of the Periodic Table The properties and behavior of matter hinge on how chemical elements bond and interact. As scientists push toward the heaviest elements, from actinides to superheavy varieties, traditional methods face challenges in producing, isolating, and studying these elusive atoms. A promising approach gaining traction is ion recycling —…

Astronomers Spot a White Dwarf That’s Still Consuming its Planets
Unexpected Activity Around a Dying Star Astronomers have identified a white dwarf that appears to be actively consuming remnants of its former planetary system. This surprising discovery challenges long-held assumptions about how planetary bodies survive, break apart, or are torn apart after their star ends its life on the main sequence. By studying the chemical…

Interstellar Comet 3I/ATLAS Brightens as it Passes Behind the Sun
What makes 3I/ATLAS special? Interstellar 3I/ATLAS is one of the few known visitors from beyond our solar system. Unlike the comets and asteroids that orbit our Sun, 3I/ATLAS originated from another star system, likely sent drifting through the galaxy long before humanity existed. Its journey offered astronomers a rare chance to study material from another…
