For stable samples we rarely need to obtain spectra in a hurry, and commercial spectrometers generally operate on timescales ranging from a few minutes to several hours.

It consisted of a telescope and camera that obtained astronomical images and spectra in the far ultraviolet region of the electromagnetic spectrum.

Heliophysics studies were made by obtaining spectra and images of the solar wind, the solar bow cloud, and other gas clouds in the solar system.

Astronomical studies by obtaining direct evidence of intergalactic hydrogen, and spectra of distant galaxy clusters and within the Milky Way.

But on one exceptional night in May 1998, astronomers using the Keck were able to obtain distinct images and spectra of Pluto and Charon.

He became principal investigator of experiment S-013 which obtained ultraviolet stellar spectra during the Gemini 10, 11, and 12 flights.

He obtained spectra of novas and nebulae.

Integral field spectrographs are used to speed up such observations by simultaneously obtaining spectra in a two-dimensional field.

Obtaining complete spectra for stars through spectrometry is much more involved than simple photometry in a few bands.

Starting at the feet and moving up the image, they began obtaining spectra.
