Tony Hawks (red dwarf fame) in a psychological thriller, where his mental state is slowly revealed to be a facade of someone who went insane years before (shutter island, etc)

It’s a shame we can’t just have 2 satellites flying in tandem, one to gather and reflect light and a much smaller one to receive the focused light, removing the need for struts. Although I imagine cost and the potential for it to go wrong precludes it happening

Tau figure is sublime!

Thanks for the info and the wonderful imagery!

That’s a great capture! Flickr really does it justice
I’m intrigued by this region though, is it that a linear of impacts created the depression line, or are they subsidence following the larger impact nearby?

Such a brilliant image!
I especially love the convection zone creating the dolphin shape:

I hadn’t realised how non-standard it was to buy the glasses, so I’ll be using @astroroyalscot.bsky.social ‘s colander tip!

Thank you for getting back to me, I love seeing what people are able to resolve from the sky outside of institutions

Is this a cluster, a gas cloud, or a galaxy in its own right?
You’ve gotten some great captures!

Is this circular pattern to the top right of the image likely a lens artefact? Or is it present in M101 itself?

As we’re looking at the expansion rate billions of years ago, and not as it is today, isn’t the more accurate measure based on the closest objects?
Are we not essentially watching a record of the early expansion in those distant objects, moving closer to the ‘live view’ the closer we look to Earth?

Being unable to find an answer online, can I ask:
When using spectroscopy to determine elements in the atmosphere of a distant object, how do we account for elements present in the interstellar medium which could alter the photons we detect?

Is the little smudge just above Jupiter one of its moons?

Would we have to do anything about the increased exposure to radioactivity on the moon (and in the ice) before we could use the water locked up in it?
