Mysterious Be-10 Spike in Pacific Ocean Points to Possible Nearby Supernova
Stellar Echoes on Earth: A Be-10 Anomaly Emerges A surprising signal has emerged from the depths of the Pacific Ocean: a spike in the radioactive isotope beryllium-10 (Be-10) embedded in seafloor sediments. Be-10 is formed when cosmic rays collide with atoms in Earth’s atmosphere, showering the surface with particles that eventually settle into the oceans…

Rock Giants: Uranus and Neptune Could Redefine Ice Giants
Could Uranus and Neptune Really Be “Rock Giants”? For decades, the outer planets of our solar system have been labeled the “ice giants,” a term that highlights their supposed abundance of water, ammonia, and methane ices alongside rocky cores. A new study, accepted for publication in Astronomy & Astrophysics, is sparking a lively debate by…

Rogue Planet Baked by Auroras: JWST Finds a Sunless World
JWST Sights a Rogue Planet Baked by Auroras In a groundbreaking study published in Astronomy & Astrophysics, an international team used the James Webb Space Telescope to scrutinize a rogue planet — an object formed in a stellar system but later ejected into interstellar space. With no nearby sun to illuminate its atmosphere, the planet…

JWST Finds Bizarre Planet Baked by Auroras, Far From Any Sun
A Rogue World Illuminated by Auroras A new study published in Astronomy & Astrophysics reports that the James Webb Space Telescope (JWST) has observed a rogue planet — a planetary-mass world drifting in interstellar space, unbound to any star. Far from any solar heat, this world nonetheless shimmers with auroral light across its upper atmosphere.…

Rogue Planet Auroras Bake a Bizarre World, JWST Finds
Rogue Planet Auroras: A New Kind of Heat Source A recent study published in Astronomy & Astrophysics reports a striking finding: a rogue planet wandering the galaxy—unbound to any star—exhibits auroral emissions so intense they effectively bake parts of its atmosphere. The discovery comes from observations made with the James Webb Space Telescope (JWST) and…
