1 00:00:07,800 --> 00:00:10,620 A Universe Aglow 2 00:00:12,000 --> 00:00:20,260 ESO's Very Large Telescope has uncovered a faint omnipresent glow surrounding distant galaxies. 3 00:00:21,280 --> 00:00:27,500 By gazing deep into the famous Hubble Ultra Deep Field... 4 00:00:28,440 --> 00:00:35,240 ...VLT's MUSE spectrograph saw nearly the entire field of view glowing. 5 00:00:36,140 --> 00:00:43,080 This glow is caused by clouds of hydrogen that surround galaxies in the early Universe. 6 00:00:44,480 --> 00:00:51,480 MUSE's exquisite sensitivity allowed us to observe these dimly shining clouds... 7 00:00:52,620 --> 00:01:00,700 ...and showed that the glowing hydrogen illuminates almost the whole night sky. 8 00:01:03,280 --> 00:01:09,860 Transcribed by ESO; Translated by —
