The spins of some early galaxies could be a clue that the entire observable universe exists within a black hole—except, that is, for all the evidence to the contrary

A spiral galaxy known as NGC 4945 exhibits powerful winds of material blowing from the supermassive black hole located at its core in a new photo taken by the Very Large Telescope in Chile.

A long-simmering disagreement over the universe’s present-day expansion rate shows no signs of resolution, leaving experts increasingly vexed

A California man has been sentenced to jail for flying a drone over Vandenberg Space Force Base and photographing the installation.

At the heart of the Trump administration’s Signal scandal lies the familiar psychological pitfall of groupthink

Blackholes are a fascinating class of object to study. We have learned significant amounts over the years but one of the outstanding mysteries remains; how there were supermassive black holes with millions or even billions of times the mass of the Sun present in the first billion years after the Big Bang. Our current models of stellar mass black hole evolution and mergers cannot explain their existence. A new paper suggests that ultralight dark matter particles, like axions may have done the trick and provides a mass range for expected particles.

A mysterious and often debated aspect of human sexuality colloquially known as “squirting” sparks controversy. This episode explores what research reveals.

The first astronauts to enter a polar orbit chose the obvious animal to serve as their zero-g indicator: a plush polar bear. The doll also has an emperor penguin embroidered on its chest.

As humans continue to make tentative progress out into the cosmos, the impact of space exploration on our fragile bodies is only beginning to be understood. We know that space travel decreases muscle and bone mass but a team of researchers have discovered which bones suffer the most! Using a group of mice that became astro-rodents for 37 days, they discovered that bone degeneration effective the femur most but not the vertebrae. They concluded that it’s our weight-bearing bones that suffer the most.
