3. Extreme star cluster bursts into life The star-forming region NGC 3603 - seen here in this Hubble image - contains one of the most impressive massive young star clusters in the Milky Way. Bathed in gas and dust the cluster formed in a huge rush of star formation thought to have occurred around a million years ago. The hot blue stars at the core are responsible for carving out a huge cavity in the gas seen to the right of the star cluster in NGC 3603’s centre.

Hubble also came of age at the same time as the internet, which created a great opportunity to distribute large format, high resolution images that are absolutely stunning on computer desktops and screen savers. Before that most people only saw astronomy images published in books or newspapers. “Hubble also had a fairly dramatic beginning, with the discovery of the flawed mirror and the subsequent mission where astronauts actually traveled to the telescope in order to repair it. “It is our eye on the universe, but at the same time it is an actual object in space that we can visit and even touch, which helps to bring the images it produces a little closer to home.” — Dr. Heather Knutson Assistant Professor of Planetary Science California Institute of Technology Pasadena, California
