Hubble’s Universe Unfiltered

In order to observe the most distant objects in the universe, one needs two things: very fine resolution and very long exposures. As a space telescope, Hubble provides the detailed view. However, getting several days worth of exposure for a single observation on this valuable resource is an extremely tall order, since there are many more requests from astronomers to use Hubble than there are hours available to use it. Nevertheless, Hubble has done a few deep images looking across the universe, and unveiled some dramatic findings. To call these observations mind-bending is an understatement, as one has to traverse several deep concepts about space and time before even grasping the nature of the results. Jo
