Infrared spectrum in astronomical observations
Table of Contents

Technology

Comparative outputs of the Helix Nebula and the Galactic Center region when seen with infrared light (VISTA 4.1 meter telescope) and with visible light (MPG/ESO 2.2 meter telescope) (ESO, 20091; Emerson, 20122).

This comparison shows the potential of the infrared spectrum (including the VISTA telescope) as a technological advancement for capturing clearer astronomical images. It also shows that visible light may still be better for providing a sense of volume.
