Hind's Variable Nebula

Hind's Variable Nebula and T Tauri

Hind's Variable Nebula is a reflection nebula remarkable for its changes in brightness, which are due to wide variations in the star that illuminates it – T Tauri. Discovered by John Hind in 1852, it began to fade after 1861 and had disappeared from view to even the largest telescopes of the time by 1868. It was not seen again until 1890 when it was observed by Edward Barnard and Sherburne Burnham. Since the 1930s it has been gradually brightening but remains a challenge for the amateur observer.
