"Wider field images" may dub this the Heart Nebula, but I claim this bit as The British Isles!

Re: APOD: The Moon Dressed Like Saturn (2024 Sep 01)

Has the Moon been out drinking? The ring around the Moon has slipped a bit.

Surely this does not bode well? ""Last night, the moon had a golden ring, And to-night no moon we see!"

Like Lasse, this made me think of "Gravity", and not in a good way.
Good luck to the crew of the ISS, as the Perseids peak.

What a clever set of pictures!

Surely they could be put together as an animated film, perhaps by using AI to produce interpolated images? Beyond my skills, I fear!

Then some of the secondary particles will be lighter (electrons?) and low energy, so more easily curved by weaker magnetic fields?

Some further Qs. In front of the passing view of the sky are random (?) streaks. Are these particles in the Corona, that we see further out but in front of the starry sky beyond? Or are they radiation particles, directly affecting the camera? And why are so many such streaks curved? A charged partic...

Just HOW is this a "Wolf" moon?
There are no wolves on the island where I live, and few in Europe, and anyway the animals couldn't give a F&^*&^ about it!

It's beautiful picture of a full moon! Why bring in all the false folkways?
