The giant planet’s bow shock isn’t just deflecting the solar wind, it’s acting as a powerful particle accelerator, firing electrons to relativistic energies of at least 1 MeV, according to a new analysis of data from NASA’s Juno spacecraft.

Tesla has pushed the planned public demo of its next-generation Roadster to August or later, according to a report from The Information citing four people with knowledge of the program. It marks yet another delay for the vehicle first unveiled as a prototype nearly nine years ago.

The demo, expected to take place in Texas, is meant to showcase the SpaceX cold gas thruster system that Tesla claims will allow the Roadster to achieve extreme acceleration and even lift off the ground.

Five of the seven crew members on the International Space Station briefly sought refuge inside a SpaceX return capsule Friday morning as two Russian cosmonauts worked on an air leak on the other end of the complex.

NASA ordered US astronauts Jessica Meir and Jack Hathaway, French astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev into SpaceX's Crew Dragon Freedom spacecraft around 9 am EST (14:00 UTC) on Friday. The foursome launched aboard the SpaceX crew capsule on the Crew-12 mission in February, and the ship serves as their lifeboat until the crew's scheduled return to Earth in September.

NASA astronaut Chris Williams, who flew to the station in a Russian Soyuz ferry ship, joined the Crew-12 astronauts inside the Dragon spacecraft.

For decades, astronomers suspected that something vast lurked behind the Milky Way’s dense, dusty disk in our sky. There were indirect, subtle distortions present in galaxy motions that we could see, showing unexplained gravitational pulls. But the structureContinue reading "Giant supercluster discovered hiding behind the Milky Way"
