Virgin Orbit rocket launches 7 US defense satellites

A Virgin Orbit rocket carrying seven U.S. Defense Department satellites was launched from a special Boeing 747 flying off the Southern California coast and streaked toward space Friday night.

Triply eclipsing stellar systems

Stars with the mass of the sun or larger are typically accompanied by one or more orbiting companion stars. The system forms when gravity contracts the gas and dust of an interstellar cloud until clumps develop that are dense ...

A new method for predicting the 11-year solar cycle strength

Scientists from Skoltech and their colleagues from the University of Graz & the Kanzelhöhe Observatory (Austria), Hvar Observatory (Croatia), and the Belgian Solar-Terrestrial Center of Excellence—SILSO, Royal Observatory ...

Capturing the onset of galaxy rotation in the early universe

As telescopes have become more advanced and powerful, astronomers have been able to detect more and more distant galaxies. These are some of the earliest galaxies to form in our universe that began to recede away from us ...

A giant black hole that spins slower than its peers

Astronomers have made a record-breaking measurement of a black hole's spin, one of two fundamental properties of black holes. NASA's Chandra X-ray Observatory shows this black hole is spinning slower than most of its smaller ...

Another Webb telescope instrument gets the 'go for science'

The second of NASA's James Webb Space Telescope's four primary scientific instruments, known as the Mid-Infrared instrument (MIRI), has concluded its postlaunch preparations and is now ready for science.

Two Seattle startups racing to transform next-gen space travel

The phrase "nuclear energy" conjures images of large steaming towers or Tony Stark's arc reactor from the iconic "Iron Man" movies. But two Seattle-based startups are designing nuclear technologies small enough to pick up ...

Smart earbud will measure how astronauts sleep

Sleep is important for our health and well-being, and bad sleep can negatively impact our attention span, memory, decision-making skills, creativity and judgment.

The rings of Uranus and Neptune could help map their interiors

Mapping the interior of the ice giants is difficult, to say the least. Not only are they far away and therefore harder to observe, but their constant ice cover makes it extremely hard to detect what lies underneath. So scientists ...

Image: Tenoumer Crater, Mauritania

Deep within the Sahara Desert lies one of the best-preserved craters on Earth. On Asteroid Day, the Copernicus Sentinel-2 mission takes us over the almost-perfectly circular Tenoumer Crater in Mauritania.

NASA mission aims to study ice and water on the moon's surface

In the fall of 2023, a U.S. rover will land at the south pole of the moon. Its mission: to explore the water ice that scientists know lurks within the lunar shadows, and which they believe could help sustain humans who may ...
