| Description | The Telescope was created by Lacaille in the 1750s to honor the instrument that transformed astronomy since Galileo first turned one to the sky in 1609. It sits in a faint region of sky south of the rich Sagittarius-Scorpius Milky Way. The constellation contains RR Telescopii — one of the most luminous novae ever observed, a symbiotic nova that erupted around 1944 and is still slowly fading; it consists of a white dwarf accreting material from a giant companion star, undergoing a continuous slow thermonuclear burn on its surface that has kept it glowing for over 80 years — an extraordinary and sustained stellar event. |
