The most detailed 3D map of the Universe ever made

Each image is one gigabyte. With a few hundred exposures per night. Producing terabytes of data per day. For a petascale data set in total mapping 300M+ galaxies.

Roughly the same data set size as the recently released cubic millimeter electron microscopy volume of human brain connectome ;)

That's why as a 50 years old dude I study data science. Those of us old enough have grown on basis of microscopic data size. Time to adapt :-)

I for one welcome our new googol-sized-datasets overlords.

I was wondering why an article about a map did not include a picture of the map.

There's been a few posts over the past week about this. Here are two with a reasonable amount of discussion:

Alien 3D maps are in a weird file format that no one can open, so we we're stuck with this human created data for now.
