Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.
GIANT stands for Goddard Image Analysis and Navigation Tool, and it is basically an optical navigation software. That’s right, it uses images snapped by cameras, lidar, and other sensors to find the best way forward, kind of like we humans do when we use our eyes to see where we’re going....
The second-largest planet in our solar system will glow extra-bright with a golden light in the coming days....
Jupiter-sized “planets” free-floating in space, unconnected to any star, have been spotted by the James Webb Space Telescope (JWST).
Magnetars are some of the most extreme objects we know about, with magnetic fields so strong that chemistry becomes impossible in their vicinity. They’re neutron stars with a superfluid interior that includes charged particles, so it’s easy to understand how a magnetic dynamo is maintained to support that magnetic field. But...
Four years from now, if all goes well, a nuclear-powered rocket engine will launch into space for the first time. The rocket itself will be conventional, but the payload boosted into orbit will be a different matter....
