Abstract
Searches for very-high-redshift galaxies over the past decade have yielded a large sample of more than 6,000 galaxies existing just 9002,000million years (Myr) after the Big Bang (redshifts 6>z>3; ref. 1). The Hubble Ultra Deep Field (HUDF09) data have yielded the first reliable detections of z≈8 galaxies that, together with reports of a β 3-ray burst at z≈8.2 (refs 10, 11), constitute the earliest objects reliably reported to date. Observations of z≈78 galaxies suggest substantial star formation at z>910 (refs 12, 13). Here we use the full two-year HUDF09 data to conduct an ultra-deep search for z≈10 galaxies in the heart of the reionization epoch, only 500Myr after the Big Bang. Not only d..
