The blue GHOST spectrum

The GHOST blue-arm spectrum of HD 222925, a remarkably bright, chemically complex star. This star is a prime example of the type of object that GHOST will investigate. The spectrum measures light from around 350 nm to around 550 nm. Light that is ‘bluer’ than 380 nm is ultraviolet and is invisible to our eyes.
