Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars across the Milky Way.
Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds. The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging, and a new generation of highly tunable lasers.
A total solar eclipse will plunge parts of Europe into darkness on August 12, 2026, with Spain offering some of the best views. ESA will livestream the spectacle from the Javalambre Observatory, combining telescope feeds, drone footage, and expert commentary. At 20:31 CEST, the observatory will experience 1 minute and 21 seconds of totality, revealing the Sun’s normally hidden outer atmosphere.
James Webb has captured a striking new infrared view of NGC 2392, the Lion Nebula, revealing the dramatic aftermath of a dying Sun-like star. At its center, a scorching white dwarf is blasting radiation into surrounding gas and dust, carving out the nebula’s lion-like face while illuminating a sprawling “mane” of surviving dusty clumps.
