On this day: 18 August 2011!


On this day in 1868, the French astronomer Pierre Jules Csar Janssen (1824-1907), discovered helium whilst observing a solar spectrum during a solar eclipse at Guntur, in Andhra Pradesh, India.

On display in the MUSA Collections Centre is a sample of helium that was used in the world’s first helium-filled airship, the U.S. Navy’s C-7, which flew its maiden voyage from Hampton Roads, Virginia to Bolling Field in Washington, D.C. on December 1, 1921! If you would like to see this object, you can arrange a visit by contacting Claire Robinson, Project Officer, on cr67@st-andrews.ac.uk or 01334 461 699.
