Astronomers say they’ve spotted the first miniature quasar pointed at Earth
Microblazars — a miniature version of blazars — may be responsible for mysterious ultra-high-energy particles.
ESA’s Euclid Space Telescope Finds Universe’s Most Ancient Quasars
Led by ESA (European Space Agency) with contributions from NASA, the Euclid space telescope has discovered 31 of the oldest quasars ever documented. In
Monster black holes are silencing star formation across the universe
A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear faint or missing. The finding suggests galaxies grow and evolve together, not in isolation.
Scientists Solve a 70-Year Mystery Behind the Universe’s Strange Magnetic Fields
Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, but their origin has remained one of plasma astrophysics’ most persistent mysteries. Planets, star
Something fundamental about black holes may be changing
New observations reveal that the relationship between ultraviolet and X-ray light in quasars has changed over billions of years. This unexpected shift suggests the structure around supermassive black holes may evolve with time, challenging a decades-old assumption.
New cosmic lensing test sharpens the Hubble tension and hints at new physics
New analysis of quasar time delays points to a faster-expanding universe, making the gap with early-universe predictions harder to dismiss.
