This month, the SpaceX Crew Dragon spacecraft will make the first fully-private, crewed flight to the International Space Station. The going price for a seat is US$55 million.

Around the world, astrophysicists are poring over the blips of gravitational waves that ripple through Earth when distant black holes or neutron stars collide. Most don't also attend high school.

Researchers have spotted what might be the farthest astronomical object ever found — a galaxy candidate named HD1 that they estimate is 13.5 billion light-years away.

Abrams Books delivers another stellar "making of" edition with "The Art of Star Wars: The Mandalorian" Season 2

Scientists discovered the mechanism that causes electrons to 'downpour' into Earth's atmosphere.

Side-lit by the Sun, its heavily cratered surface mired in shadow, the south pole of the Moon represents a highly challenging lunar landing target. Italian ESA astronaut Roberto Vittori took to an advanced flight simulator to try out a mock polar touchdown as part of a project to design a ‘human-in-the-loop’ lunar landing system.

NASA’s Artemis 1 moon rocket and SpaceX’s Falcon 9 shared the scene Wednesday at the Kennedy Space Center — the first time since 2009 that rockets have stood on both pads at Launch Complex 39.

Bjarni Tryggvason, one of Canada's original astronauts, has died at the age of 76. Selected by the National Research Council of Canada in 1983, Tryggvason launched with NASA's STS-85 crew in 1997.

When comets first appear near Earth, their bright tails of ionized gas stun observers, but on every subsequent return, they become dimmer.

The two rockets — NASA's SLS and SpaceX's Falcon 9 — can be seen together in photos that NASA posted to one of its Flickr accounts today (April 6).

SpaceX rolled a Falcon 9 rocket and Dragon capsule to their launch pad Tuesday at the Kennedy Space Center, setting up for an engine test-firing Wednesday and launch Friday of four private space fliers on a 10-day mission to the International Space Station.

Unlike the short "joyrides" of Richard Branson and Jeff Bezos, this mission will be reaching the roughly 400km altitude needed to dock with the ISS.

Scientists found a remarkably stable 'black widow ' pulsar that could be used to help detect gravitational waves.
