SpaceX postponed Wednesday what would have been its first commercial launch with the Falcon Heavy rocket, citing strong wind in the upper atmosphere.
At tens of thousands of kilometers above the Earth, a Russian satellite slowly approached the French-Italian satellite Athena-Fidus in October 2017, a move France later denounced as "an act of espionage."
SpaceX's Falcon Heavy rocket is poised for its first commercial space launch Wednesday, carrying a Saudi satellite operated by Arabsat, a year after sending founder Elon Musk's red Tesla roadster into orbit as a test.
The world is finally about to see a black hole—not an artist's impression or a computer-generated likeness, but the real thing.
Two NASA CubeSats teamed up on an impromptu optical, or laser, communications pointing experiment. The laser beam is seen as a brief flash of light close to the center of the focal plane, to the left of Earth's horizon.
Massive, ravenous, powerful beyond measure -– physicists are convinced that black holes exist, even if no one has directly observed one.
Managing the health of astronauts orbiting Earth at 28 000 km/h is a challenge, but how will we equip astronauts to stay healthy and deal with any medical emergencies during missions to the Moon or Mars?
Engineers designing ESA's Hera planetary defence mission to the Didymos asteroid pair are developing advanced technology to let the spacecraft steer itself through space, taking a similar approach to self-driving cars.
When the supermassive black holes at the center of galaxies accrete material, they can eject powerful jets of charged particles at speeds approaching that of light. These particles in turn emit radiation across the electromagnetic ...
