For the lazy it's a next level microscope making a short video of two 0.2nm black dots jamming into each other, walled in by grey carbon nanotubes.

They used TEM for imaging. https://www.umassmed.edu/cemf/whatisem/

Read the article, it didn't capture the minutia of a bond happening, just a few frames of what atoms look like when they do bond.

And 0.2nm is 1mm divided by 5 million.

And the other way 1g of rhenium contains 3234111231049296000000 atoms (3.23 x 10^21).

This experiment is looking at the joining of 2 individual atoms.
