About this image

M92 is actually an intrinsically brighter cluster than M13 but because of its greater distance from us, 26 light years, it appears smaller. M92 is also remarkable for being the oldest globular cluster in our Milky Way, at 14.2 billion years, roughly the age of the universe. M92 is around 110 light years across.

Weather: 13^oC. 83% Humidity, pressure 997mb
