The Shenzhou-21 crew on board China’s orbiting space station completed its first extravehicular activities on Tuesday, Dec. 9th, during which they validated the new EVA spacesuits.

A team of researchers from the University of Zurich and the NCCR PlanetS is challenging our understanding of the interior of the Solar System’s planets. The composition of Uranus and

For roughly two billion years of Earth’s early history, the atmosphere contained no oxygen, the essential ingredient required for complex life. Oxygen began building up in the atmosphere during the

Astronomers have performed the deepest radio observations ever of Omega Centauri, searching for signs of an intermediate mass black hole thought to lurk at its center. Despite 170 hours of

Researchers have discovered that a close encounter with a rogue planet or brown dwarf during the Sun’s early years could have triggered the reshuffling of our Solar System’s giant planets.

Astronomers at the University of Tokyo have used gravitational lensing to measure how fast the universe is expanding, adding weight to one of cosmology’s most intriguing mysteries. Their technique exploits

A new study, analyzing over 1,600 galaxies observed with Chandra over two decades, suggests that smaller galaxies do not contain supermassive black holes nearly as often as larger galaxies do.

In the early 20th century, after years of effort, Albert Einstein developed his general theory of relativity. This was a massive improvement in our understanding of gravity, giving us a

Tracking down resources on the Moon is a critical process if humanity decides to settle there permanently. However, some of our best resources to do that currently are orbiting satellites

Radio astronomers hunting for the faint whispers of the early universe face an unexpected threat from above: satellites designed to be silent are leaking radio noise into space. New research
