"Exploring the Early Universe: Rapid Formation of Galaxies Unveils Cosmic Mysteries. Just 1.4 billion years post-Big Bang, massive elliptical galaxies emerged, challenging traditional models. The infographic highlights a rapid assembly process and compares the high star formation rate and swift assembly of protocluster SPT2349-56 with our modern Milky Way."
Researchers have found a candidate millisecond pulsar near the supermassive black hole at our galaxy's center—a potential "cosmic clock" to test Einstein's theories.Deep in the chaotic center of the Milky Way lies Sagittarius A* (Sgr A*), a black hole 4 million times the mass of our sun. Finding a pulsar near this monster has been a holy grail for astronomers.
A China-led space telescope has captured a rare cosmic meal: an intermediate-mass black hole tearing apart a white dwarf star.On July 2, 2025, the Einstein Probe (EP) detected a flash so bright it defied explanation. It wasn't a standard gamma-ray burst. The X-ray signal appeared before the explosion, flared to immense brightness, and then vanished in just 20 days.
How did massive galaxies exist just after the Big Bang? New research reveals they didn't grow slowly—they exploded into existence. For two decades, astronomers have been puzzled by a timeline problem. Massive, "old" elliptical galaxies were found existing just 1.4 billion years after the Big Bang. According to standard models, they shouldn't have had time to grow that big.
