James Webb space telescope: thousands of galaxies in a grain of sand

This week, Nasa unveiled the first images from the James Webb space
telescope – much awaited pictures that show our universe in
glorious technicolour. The $10bn telescope, now 1 million miles
from Earth, will allow scientists to look back to the dawn of time.
Prof Ray Jayawardhana, who is working with one of the instruments
onboard the JWST, speaks to Ian Sample about what these images show
us, and what they mean for the very human quest of discovering our
place in the cosmos.. Help support our independent journalism at
