Top Ten JWST Facts!

The James Webb Space Telescope looks nothing like the Hubble Space Telescope shown here.

As excitement mounts ahead of the launch of the James Webb Space Telescope (JWST) later this month I thought I would, as a service to the community, for the edification of the public at large, and despite popular demand, present my list of Top Ten JWST Facts.

  1. The JWST spacecraft will orbit the Sun near the Second Lagrange Point, L2, because it took so long to get built that tickets were no longer available for L1.
  2. JWST cost $10bn but its telescope is so sensitive that it can see back to redshifts greater than ten, meaning that it sees light that was emitted when its budget was less than $1 bn.
  3. To provide secure backup storage of the complete JWST data set, NASA has commandeered the world’s entire stock of 3½ inch floppy disks.
  4. As well as observing the Universe’s first galaxies and revealing the birth of stars and planets, JWST will look for signs that there might be intelligent life somewhere in the Universe.
  5. JWST’s unique 6.5m deployable mirror was  especially designed by experts from the IKEA company in Sweden who are famous for making items for ‘easy self-assembly’.
  6. The angular resolution of JWST is  0.1 arc seconds, which means  it could resolve a football at a distance of 550 km (or even further if it had Sky Sports).
  7. The Near-Infrared Spectrograph on JWST will be able to make simultaneous measurements of up to 100 sources while at the same time making a cup of coffee and washing the dishes.
  8. The BBC will be shortly be broadcasting a new 26-part TV series about JWST. Entitled WOW! JWST! That’s Soo Amaazing… it will be presented by Britain’s leading expert on infra-red astronomy, Professor Brian Cox.
  9. Er…
  10. That’s it.

    The Ashes start tonight; can it broadcast a free live feed if there is no cloud?
