Lam-2

Its story

Lambda-2 Tucanae is a yellow G-type star 222 light-years away, a solitary light in the southern constellation of the Toucan, a sky so sparsely populated that it served sixteenth-century European navigators as a reference in southern seas. The constellation itself was carved out of the unmapped austral sky by Dutch astronomers Keyser and de Houtman around 1597. The light reaching us tonight set out around 1804, when Beethoven was premiering his Third Symphony in Vienna.
