AkaSci 🛰️ | Redshift for distant objects can be estimated from their light spectra and noting the wavelengths of known emission and absorption lines. The Lyman-α break at 0.1215 µm is a distinct ultra-UV wavelength in astronomy; wavelengths shorter than it are absorbed by H in the source galaxy and in inter-galactic space. Redshift causes these wavelengths to get stretched. For JADES-GS-z14-0, Lyman-α was detected at 1.867 µm, i.e., z = (1.867 - 0.1215) / 0.1215 = 14.32. https:// webbtelescope.org/contents/med ia/images/01HZ0AGNJ96R1GSR956QYMFCRE # JWST 3/n
