Well, for the longest time, I could only see it's inverted.

But maybe if you look around the image, suddenly it will switch perspectives for you.

What type of image did you see first?

Are you like me and need proof it's not actually inverted?

Well, have a look at the same region but from a different angle.

Seeing it like this makes me wonder how I could have seen anything else.

This is a small region on the moon called Inna.

It's only 2-3km wide and 64m deep, and no one really knows how something like this formed.

It's one of several similar regions on the moon, although this one is the most prominent.

To a certain degree, a similar optical illusion can happen with small craters.

Do you see domes here, or craters?

Sometimes rotating the picture can help get the right perspective.

That's why the LRO is so useful in my opinion.

Not only do we get top-down views, but oblique perspectives too.

Moving on to another unusual lunar region, let's have a look at Komarov crater.

This crater would be pretty normal by lunar standards were it not for the fact that it has huge fracture lines running across the base.

Komarov crater itself is even bigger than Jackson crater, at 95km in diameter, meaning these are up to 500m deep and 2.5km wide.

It is believed that 2.6 billion years ago, magma built up under the crater, causing large amounts of pressure to fracture the crust, although it appears that the magma never made it to the surface, meaning the fractures were never filled in, and it remained like that ever since.

But although it didn't happen in this instance, there are examples on the Moon of magma breaking through and pooling on the surface.

One such example can be found west of Plato Crater, a large 100km wide crater seen towards the north of the moon, visible with a telescope or binoculars on Earth.
