Black holes power some of the most energetic phenomena in the known universe, but could they ever power an advanced human civilisation?
An extreme protocluster gathering of infant galaxies is hiding a vast cosmic fuel tank that is powering 400 million years of intense star formation.
The most distant and earliest "dead" massive galaxy ever seen shows some galaxies lived fast and died young shortly after the Big Bang.
South Korea conducted a test inside the former Hamtae mine in late March, deploying prototype moon rovers equipped with tech that could be used in space mining.
In the early universe, primordial black holes could acquire a "dark charge," giving them an unnaturally long lifetime, new research suggests. This makes them an interesting candidate for dark matter.
A fresh analysis of a decade's worth of Hubble Space Telescope observations shows Uranus takes 17 hours, 14 minutes and 52 seconds to complete a full rotation — 28 seconds longer than the estimate provided by NASA's Voyager 2 spacecraft nearly 40 years ago.
In 23 billion years, these two white dwarf stars will collide. Then, they'll explore. Here's why scientists say this discovery is such a big deal.
A sudden stratospheric warming event reversed the winds that make up the northern polar vortex on March 9. A new animation shows the vortex also moved away from the Arctic towards Europe.
Extraordinarily powerful light from gamma-ray bursts might help produce heavy elements from the outer shells of dying stars.
Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent.
