Astronomers have recorded the most luminous flare ever emitted by a black hole—an event so extreme it briefly outshone the ...

This NASA/ESA Hubble Space Telescope image features the spiral galaxy Messier 77, also known as the Squid Galaxy. Everything on Earth, in our solar system, our galaxy, and beyond is contained within ...

Distance scales from the Planck length to a 93-billion-light-year observable universe expose extreme limits of physics and hint at unknown phenomena where current laws break down.

New research has unveiled images of the universe in its infancy—a mere 388,000 after the Big Bang. The snaps of the universe were produced by the Atacama Cosmology Telescope collaboration (ACT), which ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or mathematician to tell you about fascinating ideas from their corner of the ...

The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

Japanese physicists have revived Kelvin’s old idea of cosmic knots, showing how these tangled fields might explain why matter ...

In today’s bleak media landscape of legitimate news existing alongside rampant chatbot hallucinations and a social epidemic of disinformation, it should go without saying that you can’t believe ...

Sometimes, a picture can be worth much more than a thousand words. For instance, one measure associated with the pictures below—new high-definition snapshots of the cosmos in its infancy—is 1,900 ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...
