When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and...

Last year LIGO announced the detection of gravitational waves from the merger of two black holes. The science world went a little crazy. Only a few weeks ago a new rumour emerged: that LIGO had, for the first time, spotted gravitational...

The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form...

James Webb captures infrared light, which allows us to see billions of light years away. Some galaxies would not be visible otherwise, because their light has redshifted beyond visible light spectrum due to the...

SUMMARY

The universe is full of opposing forces balanced in a celestial tug-of-war, until they sometimes aren’t. In stars, the two opposing forces are gravity which tries to collapse the star inward, and...

What are the odds a supernova could end the world tomorrow?

Discover how dying stars transform into black holes, areas of mass so great that even light can't escape. Physics - Universe - Learning Points. When a star dies, it collapses and condenses into a single point, known as a singularity. The...
