Happy Birthday Hubble

Today, 24 April 2015, the Hubble Telescope turns 25 years old. During its quarter-century, the Hubble has produced an incredible array of now iconic images, including the famous Hubble Deep Field—where the telescope aimed its lens at a tiny speck in space for 10 days, revealing thousands of galaxies. The Hubble has been an enormous aid to astronomers and has been hailed one of the most productive scientific instruments ever constructed. To celebrate Hubble’s birthday, The Guardian has rounded up some of its most remarkable images.
