Caption: The recently discovered LAEJ095950.99+021219.1 galaxy is extremely faint and was detected by the light emitted by ionized hydrogen. The search employed a technique ASU professors James Rhoads and Sangeeta Malhotra pioneered that uses special narrowband filters that allow a small wavelength range of light through. In this photo, a narrowband filter is being mounted in a filter holder for use in the instrument IMACS (the Inamori-Magellan Areal Camera & Spectrograph). IMACS was built by a team at the Observatories of the Carnegie Institute of Washington, led by Alan Dressler.
