NASA: Record-breaking black hole discovered by Webb and Chandra telescopes
Watch an intermediate-mass black hole take a bite of a wayward star and then fling the leftovers across the galaxy. Using not one, but two powerful NASA space telescopes, astronomers have discovered a black hole so distant it could reveal how some of the first supermassive black holes formed. Researchers combined data from NASA’s Chandra…

Boom in satellites changes the sky forever
Astronomers have classified a new object among the brightest in the sky. It’s not a star or a planet: it’s BlueWalker3, the prototype for a new fleet of dozens of satellites that will provide a 5G WiFi connection from space. Achieving the technological goal of being able to be connected anywhere on the planet is…
