This spectacular spiral galaxy, known as NGC 1964, resides approximately 70 million light-years away in the constellation of Lepus (The Hare). NGC 1964 has a bright and dense core. This core sits within a mottled oval disc, which is itself encircled by distinct spiral arms speckled with bright starry regions. The brilliant centre of the galaxy caught the eye of the astronomer William Herschel on the night of 20 November 1784, leading to the galaxys discovery and subsequent documentation in the New General Catalogue. In addition to containing stars, NGC 1964 lives in a star-sprinkled section of the sky. In this view from the Wide Field Imager (WFI) an instrument mounted on the MPG/ESO 2.2-metre telescope at ESOs La Silla Observatory, Chile the star HD 36785 can be seen to the galaxys immediate right. Above it reside two other prominent stars named HD 36784 and TYC 5928-368-1 and the large bright star below NGC 1964 is known as BD-22 1147. This view of NGC 1964 also contains an array of galaxies, visible in the background. The WFI is able to observe the light from these distant galaxies, and those up to 40 million times fainter than the human eye can see.
