(Sen)
Click play, go full-screen, lean back and enjoy. That's how easy it is now to get lost in the absolutely stunning scape that is our planet Earth from space as it streams live before your eyes. Sen, a company based in London, provides views of Earth from orbit, with the hopes of making an experience usually reserved for astronauts a little more accessible to the rest of humanity. It's live video of Earth from space, 24 hours a day and seven days a week.

Lone NASA radar dish steps up where Arecibo fell
(NASA/JPL-Caltech)
Rising out of the remote Mojave Desert, NASA's Goldstone Solar System Radar is a solitary satellite dish that communicates with spacecraft. In its downtime, the facility's antennas can track objects in space as they pass by Earth, improving measurements of their orbits that help scientists calculate if a particular target has a chance of colliding with our planet. By the end of 2024, Goldstone had detected 55 Near-Earth Asteroids, setting a new annual record for the facility.

Night sky for tonight: Visible planets, stars and more
(Starry Night)
Tonight, a 94% waning gibbous moon will rise in the east a couple of hours after sunset, which is a great time to get outside and watch a moonrise. Once it's up, you'll see that the top-right of the moon, as we look at it from the Northern Hemisphere, is in darkness, with the terminator - which separates day and night on the moon - slicing through some interesting terrain. The shadows will make it relatively easy to see Mare Crisium, the "sea of crises," as well as some obvious craters along the top of the moon. Binoculars will give you a tremendous view.

Spaceships near the speed of light would appear rotated
(Fug4s/Getty Images)
In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. This doesn't mean the rocket literally contracts, but rather that it appears contracted to an observer. Astronauts on board the rocket, for example, would still measure their spacecraft to be the same length that it has always been. It's all relative - hence the name of the theory.

SpaceX fires up Starship spacecraft ahead of 9th test flight
(SpaceX)
SpaceX's latest Starship vehicle has breathed fire yet again. It was the third static fire for this particular vehicle, which "is undergoing final preparations for the ninth flight test," according to a Tuesday (May 13) SpaceX post on X that shared a video and photos of the trial. The company has not yet announced a target date for Flight 9, but it could happen in the next few weeks. SpaceX has already performed a static fire with the first-stage booster that will launch on the mission.
