"molecules from the rocket exhaust produce photons at a wavelength of 6300 Å – the same color as red auroras."
Anyone else have this use of Ångström trigger an exception in their brain? The unit of default for wavelength is nm, not Å… (1nm=10Å)

Anecdotally I've only really heard angstroms used in material science / condensed matter physics, where most small structures are small integer numbers of angstroms across.
