Even down on the Red Planet's surface, the Curiosity rover might be able to get in on the act: Because Mars's atmosphere has no ozone to block ultraviolet light, sensors on the rover will be able to detect those wavelengths and thereby monitor certain trace gases spewing from the comet — unless a dust storm blocks the view to space, Lemmon says.

The light - absorbing molecules break off from the chains when exposed to ultraviolet light at 350 nanometers wavelength, triggering degradation of the plastics.
By the time it stops working, the JWST should be in orbit, but the newer telescope will operate in different wavelengths from Hubble — using infrared rather than optical and ultraviolet light.

The other part of the process, as explained in the paper, is using the high harmonic generation process to produce bright spatially coherent beams from a tabletop laser, spanning the range from the vacuum ultraviolet (wavelengths less than 200 nm) to the soft X-ray region of the spectrum (wavelengths less than 10 nm)
This large range of wavelength coverage, combined with the instrument's high sensitivity, allows the study of everything from comets (which have interesting features in the ultraviolet part of the spectrum), to the blue light from star formation, to the red light of very distant objects.
When the star's ultraviolet radiation strikes the gases in the nebula, they heat up, giving out radiation ranging in wavelength from blue — emitted by hot oxygen in the bubble near the star — to yellow — emitted by hot hydrogen and nitrogen.
