Why should a little storm in the distance shut down a Falcon 9 launch? History, the tricky timing of matching orbits, and complex meteorology.
SpaceX's latest Starship prototype exploded just after a rocket engine test Friday (May 30), erupting in a dramatic fireball at the spaceflight company's Texas proving grounds.
SpaceX and NASA are about to make history, sending astronauts from U.S. soil to the International Space Station. And you can watch it all here.
Despite warnings from NASA officials and the risks implied by the current pandemic, approximately 150,000 people gathered on Florida's space coast to watch the Crew Dragon launch.
If you're frustrated that you now have to wait until Saturday (May 30) to see SpaceX's first crewed launch, you can blame Mother Nature and orbital mechanics.
Twin shock waves produced by the galaxy's central black hole could have inflated the gargantuan Fermi Bubbles about 6 million years ago, a new study suggests.
SpaceX's first-ever crewed mission, a test flight called Demo-2, is scheduled to launch at 4:33 p.m. EDT today (May 27) from NASA's Kennedy Space Center in Florida.
Physicists are figuring out how close you can get to a black hole before you are unlikely to escape. That threshold is called the innermost stable circular orbit (ISCO).
Eleven billion years ago, a hot, active, eyeball of a galaxy glared across space. It formed in a violent collision, and could help explain the Milky Way's spiral.
Scientists have a new explanation for an explosive cosmic event in 1908 that flattened trees for hundreds of miles in a remote Siberian forest.
Using gravitational waves to approximate pi, physicists see no problem with Einstein's theory of general relativity.
A new paper used an advanced "Bayesian" model to show that the emergence of intelligent life on Earth was probably a lucky break.
Russia launched a military satellite to orbit on Friday (May 22), and the mission generated plenty of drama in the downward direction as well.
Researchers using China's huge new FAST radio telescope are piecing together a technological strategy to carry out a major and sweeping search for extraterrestrial intelligence (SETI).
What if one of the strangest, most unsettling findings in particle physics turned out to be an illusion? A new study suggest a simple physical explanation for a mysterious event.
A massive, rotating disk galaxy that first formed just 1.5 billion years after the Big Bang, could upend our understanding of galaxy formation, scientists suggest in a new study.
