It’s Hubble’s 25th anniversary in space this year but it seems like we’re the ones getting all the presents! Yesterday NASA released two new high-def versions of the famous “Pillars of Creation” image, and now today there’s this: Hubble’s most detailed image ever of the Andromeda Galaxy!

Containing over 100 million stars it’s not just the best view yet of Andromeda – it’s also the most expansive image ever made with Hubble. Although the galaxy is 2.5 million light-years away it extends across an area larger than the full Moon in the sky, so to create such a detailed mosaic Hubble had to obtain 7,398 images taken over 411 individual pointings! It’s 1.5 billion pixels covering an area over 40,000 light-years across.

According to NASA, it’s “like photographing a beach and resolving individual grains of sand.” Wow!
