Sentences with phrase «faint object spectrograph»

Three spectrographs have been particularly important in this endeavor — the Faint Object Spectrograph (FOS), the Space Telescope Imaging Spectrograph (STIS), and the Cosmic Origins Spectrograph (COS).

The Faint Object Spectrograph (FOS) was one of the original instruments on Hubble; it was replaced by NICMOS during the second servicing mission in 1997.

Images taken with the Hubble Space Telescope's Faint Object Spectrograph in 1996 offered some evidence to support earlier indications that either star could be a high - mass brown dwarf (Schultz et al, 1999).

Not exact matches

The team used the Faint Object Camera and Spectrograph (FOCAS) mounted on the Subaru Telescope to thoroughly study the visible wavelength spectrum (Note 1) of the afterglow of a gamma - ray burst (GRB, Note 2), which is a violent explosion of a massive star.

Researchers were able to confirm characteristics of the Little Cub galaxy using Keck Observatory's Low Resolution Imaging Spectrograph, a faint - light instrument capable of taking spectra and images of the most distant known objects in the universe.

• Space Telescope Imaging Spectrograph (STIS) replaced Faint Object Spectrometer (FOS).

My colleagues and I were using the Echellette Spectrograph and Imager (ESI) instrument, which looks at faint objects in the visible wavelengths, to study star clusters and small galaxies.

The FOS examined fainter objects than the High Resolution Spectrograph (HRS), and could study these objects across a much wider spectral range — from the UV (1150 Angstroms) through the visible red and the near - IR (8000 Angstroms).

Redshift is a measure of how much the Universe has expanded since the light left a distant source and can only be determined for faint objects with a spectrograph on a powerful large telescope such as the Keck Observatory's twin 10 - meter telescopes, the largest on Earth.
