Webb found galaxies at redshifts above 14, existing less than 300 million years after the Big Bang, more luminous and numerous than models predicted.
Webb operates at L2; mission and science control at STScI.
What it led to
- Revision of galaxy formation models
- Search for Population III stars
- Study of reionisation
