Photographer Alex Cherney visited this remote observatory and created a really lovely time lapse video of the telescopes at work:

The telescopes taken together are called the Australian Square Kilometre Array Pathfinder, or ASKAP. The Square Kilometer Array is a project currently underway in Australia and South Africa to create the largest radio telescope in the world.

But ASKAP is a full-fledged observatory in its own right, and will add to our arsenal of instruments peering into deep space.
The video is beautiful, and as always when I watch these from Australia, I’m overwhelmed by the southern skies. The stars are different than the ones we see up here, but it’s not just that. What always gets me is how, from my own experience, the motion is ...
