Hubble: The Mirror on the Universe

The latest images from the Hubble Space Telescope's recent discoveries and fascinating updates.

In its 20 years of viewing the heavens NASA's Hubble Space Telescope has traveled 2.8 billion miles, made more than 930,000 observations and snapped over 570,000 images of 30,000 celestial objects. It has forever changed how we view the universe and our place in it.

This third edition of Hubble picks up the journey where the last edition left off. It includes a fascinating discussion on how the latest discoveries are revising scientific understanding of the universe, such as:

• The first direct observation of an "exiled" star. For every 100 million stars in the galaxy there is perhaps one hypervelocity star.
• A long-exposure image that captured the faint details of spiral galaxy NGC 4911 within the Coma Cluster of galaxies, which is 320 million light-years from Earth.
• A composite "mash-up" image of two colliding galaxies located about 62 million light-years from Earth, taken by the Hubble Space Telescope along with the Chandra X-ray Observatory and the Spitzer Space Telescope.

Since the 2007 edition of Hubble, the Hubble Space Telescope has clocked millions more miles and taken thousands more images. This new edition describes how, like the Hubble Space Telescope's missions, our view of the universe is a constantly evolving journey.
