Dr Becky got very excited about that just now this evening (Wednesday):


YouTube brief livestream: The James Webb Space Telescope mirrors are aligned!


Just got to be watched!

Enjoy!!

The JWST has a working resolution of 17 milliarcseconds? Remarkable! I've read predicted figures of 68 and 100 milliarcseconds. This presumably varies somewhat by wavelength. That appears to be 3 to 5 times better resolution than expected. I guess they were being conservative in their expectations.

Another great triumph for the JWST was the launch, the launch was so precise that only 1/2 of the fuel planned for was used which now will extend the useful life from 10 yrs to 20 yrs. A way I am looking at this is twice the life and 3 times the resolution means 6 time the science that was budgeted for. Fantastic.

The James Webb Space Telescope has now produced 14 excellent images of deep space objects, mostly distant galaxies. The video, linked below, shows each image, and includes some information about the objects themselves, and the imaging process.

Uh oh..... MicroMeteoroid hits main mirror on James Webb Space Telescope
In a statement, NASA said the impact happened some time at the end of May. Despite the impact being larger than any that NASA modeled and "beyond what the team could have tested on the ground," the space agency said the telescope continues to perform at higher-than-expected levels. The telescope has been hit on four previous occasions since launch.
