Mysterious cold streak puzzles astronomers in cosmic background

October 04, 2025 Reported by AI

A peculiar cold region in the cosmic microwave background, known as the Cold Spot, continues to baffle scientists despite years of study. Discovered over a decade ago, this anomaly appears cooler than its surroundings and may hint at large-scale structures in the universe. Researchers remain uncertain about its cause, with theories ranging from statistical flukes to massive voids.

Scientists uncover hidden energy mechanism in M87 black hole

Astrophysicists at Goethe University Frankfurt have simulated how the supermassive black hole M87* powers its massive particle jet using a new numerical code. Their findings reveal that magnetic reconnection, alongside the traditional Blandford-Znajek mechanism, extracts rotational energy from the black hole. This discovery explains the immense jets that influence galaxy evolution.
