Even when you remove the bright stars, the glowing dust and other nearby points of light from the inky, dark sky, a background glow remains. That glow comes from the cosmic sea of distant galaxies, ...

Scientists may have identified the gravitational waves that make up some of the universe's background, not just those coming from unusual events like black hole collisions. New Atlas reports that the ...

For decades, physicists have searched for one of the faintest signals in the cosmos: a background of neutrinos released by ...

It's a sobering statement that stars like the sun, more accurately all stars will die eventually—yes, even the sun. Don't panic, though, we still have a good few billion years to go so you will get to ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of ...

Our universe appears flat—but this observation still leaves plenty of options for its true shape. In fact, our cosmos could resemble a donut What shape is the universe? This question is far more ...

The detection of a predicted universal background of gravitational waves rippling across the fabric of space-time was announced last Wednesday by the NANOGrav consortium of over 190 scientists at more ...

The Universe is big, as Douglas Adams would say. The most distant light we can see is the cosmic microwave background (CMB), which has taken more than 13 billion years to reach us. This marks the edge ...

The fabric of the universe is constantly rippling, according to astronomers who have discovered a background buzz of gravitational waves. These waves may be produced by supermassive black holes ...
