Hubble Views Galaxy Lacking Dark Matter
NASA's Hubble Space Telescope took an image of a bizarre, ghostly looking galaxy called NGC 1052-DF2 that astronomers calculate to have little to no dark matter. This is the first galaxy astronomers have discovered to be so lacking in...

The End of the Universe: Hot or Cold?
We've talked at great length about the beginning of the universe, everything we know, and what we don't yet know. But everything that has a beginning must have an end. How will the universe end? How can we tell? When will it happen?...

Dark Matter Detection with XENON100
Dark matter has so far foiled most means of detection, but researchers are continuing to pursue its mysteries. They're using the most sensitive detector yet, called XENON100, to try to glimpse the particles. See how it works in this...

Dark Matter and Dark Energy: The Frontier of Astronomy
For a while now, we've been discussing all of things we know about the universe. What about some of the things we don't know? If we look to the current frontier of astronomy, we find two mystifying concepts, dark matter and dark energy....

This video shows the first 3D map of the distribution of dark matter that scientists have created by analysing the Hubble COSMOS survey - the largest survey of the Universe ever conducted by the Hubble Space Telescope.
Note how the clumping of the dark matter becomes more pronounced, moving right to left across the volume map, from the early Universe to the more recent Universe
