JWST is now in its L2 orbit, and getting ready to start work.

Thirty days after it was launched, the James Webb telescope has arrived at the position in space where it will observe the Universe.

The Lagrange Point 2, as it's known, is a million miles (1.5 million km) from Earth on its nightside.

Webb was finally nudged into an orbit around this location thanks to a short, five-minute thruster burn.

Controllers back on Earth will now spend the coming months tuning the telescope to get it ready for science.

Key tasks include switching on the observatory's four instruments, and also focusing its mirrors - in particular, its 6.5m-wide segmented primary reflector.

There's still a lot of adjustment and checking to do, but it won't be too long before we start to see some amazing images.
Looking better with each milestone passed.

The mirrors, antenna and sun shade all have deployed successfully. I wouldn't say we're home free, but this is looking more and more hopeful all the time.

And now JWST appears in a game:

(Which is actually about the Nancy Grace Roman Space Telescope.)

My top score so far is 577...

ETA: 667...
