You may have seen the Hubble Ultra Deep Field (HUDF) photo before – it is a photo of a clear patch of sky that shows over 10,000 galaxies. It is often called the most important image ever taken because it allowed scientists to estimate that there are over a 100 billion to 1 trillion galaxies in the universe.
Earlier this month a 3D animation rendered using the measured redshift of all 10,000 galaxies in the Hubble Ultra Deep Field image hit YouTube:
Quite an impressive view, isn’t it? Well … here is another one (a tiny part of the huge image below). It is a rarely seen before image that is perhaps a hundred times larger (here’s a link to the BitTorrent of the image [180 MB]) than the HUDF and thus not widely circulated.
In a way, this view is more special because rather than a static photo, it actually is an interactive composite made using the OpenZoom technology, similar to Google Maps. You can pan the “map” using the arrows on your keyboard (or by dragging its parts with your mouse). +/- (or the wheel button) can be used to zoom in and out. Also, you can press ‘F’ to enter the full-screen mode and ‘H’ to return to the original view.
The author of this composite also made available a similar view of the Orion Nebula.
