Hubble Space Telescope records Andromeda galaxy with stunning richness of detail.

By taking a sequence of photos of the Andromeda galaxy, identified as M31 by astronomers, in high definition, capturing more than 100 million stars - a relatively low figure compared to astronomical values the Hubble Space Telescope downgraded our size even further.

The image was made available by ESA, the European Space Agency, in partnership with the United States space agency, NASA, as both manage Hubble. To view it with a zoom tool directly in the browser, click here .

Due to the large size of the Hubble record, it was best to turn the image into a video, which can be watched below. "This is a cropped version of the full image and is 1.5 billion pixels long. You would need more than 600 HD television screens to display the entire image," the European agency explained.


With its 1.5 billion pixels, the image depicts a 40,000 light-year stretch of Andromeda, showing conglomerates and many stars - which are orbited by several planets and natural satellites (constituting "Extrasolar Systems"). Many of these stars don't even exist anymore, we're practically seeing "ghosts" in this small cosmic array. Soak in a small fraction ofcosmic immensity.
