A Night Observing with SAMI

This video shows scenes from one night observing galaxies with the SAMI Instrument on the 4-metre Anglo-Australian Telescope (AAT) at Siding Spring Observatory in New South Wales, Australia.

SAMI is the Sydney Australian Astronomical Observatory Multi-object Integral Field Spectrograph. Integral field spectroscopy allows a unique view of how stars and gas zoom around inside distant galaxies because we collect dozens of spectra across the entire face of each galaxy.

The new technology of SAMI includes the bundles of wires shown in orange and silver which plug into a unique metal plate. Inside the silver cords are 61 optical fibres! One bundle points at a single galaxy and captures its stars and gas swirling around in 61 different spots across the face of the galaxy. There are 13 of these galaxy hexabundles, making the survey uniquely efficient. 

This footage was shot on the night of 27 April 2014, the 40th Anniversary of the first starlight ever collected by the AAT.
