Unverified HuggingFace

21cm Hydrogen Line Sky Survey Continuous 1-second-cadence power spectra of the 21cm neutral hydrogen (HI) line at 1420.405 MHz, recorded 24/7 from a fixed omnidirectional observer on the US East Coast. What this is A radio telescope pointed at the whole sky, recording one spectrum per second, indefinitely. The Earth's rotation scans the beam across the galactic plane daily, producing a natural drift scan. Every row is a self-timestamped power spectrum spanning 2… See the full description on the dataset page: https://huggingface.co/datasets/phanerozoic/hi-21cm-survey.
