Anyone for an astronomy thread?

[torres]

What scope do you have?

Nothing too flash. Celetron with a 50mm lens.

Per Scott Manley, it's going to take several weeks to get enough observations to have an accurate measurement of the deviation.

[Ginger Yellow]

I doubt they know yet.

Did it work? I read that they'd successfully crashed into the asteroid but not whether it had made any difference to its trajectory

[Rogin the Armchair fan]

Is this the best thread for NASA managing to crash a probe into an asteroid? I thought that was pretty cool having grown up on a Hollywood diet of Deep Impact / Armageddon / Don't Look Up. Slightly reassuring to know that we now potentially have the technology to deflect a civilisation destroying meteorite.

Or create one ...

I’ll let you know once I’m home hobbes.

[hobbes]

What scope do you have?

[torres]

It’s the clearest I’ve ever seen it through the scope. Even MrsT was suitably impressed.

[hobbes]

If it's clear over the next few days, I might get Bertha out for a look.

There were some belting views of Jupiter and it’s moons last night.

[Guy Profumo]

Anyone from Scotland / NI / Ireland see or record pictures from last night's fireball?

[Discordant Resonance]

Sadly, Artemis has been postponed for a second time, due to another fuel leak.

I bet they find a Starbucks there. Or a Sbarros.

This is a good explanation of the expansion thing. It's not all expanding equally.

Space itself is expanding. So we're not "moving", as such, but we are rather like the spots on a balloon that's being inflated. I heard Brian Cox say that, so it must be right.

[Nocturnal Submission]

What boggles my mind when I think about stuff like that is that it shows that the universe is expanding faster than the speed of light, as otherwise we wouldn't be able to see the stars from billions of years ago, many of which will have long since burnt out and turned to black holes.

So we're sitting on a planet which is spinning on its axis, orbiting round the sun, inside the arm of a galaxy that's orbiting a black hole, and it's all simultaneously travelling away from the centre of the universe at faster than the speed of light, and yet, we feel none of this movement.

I feel like it's time for this:

My God, it’s full of stars!

There’s a cool documentary about how they arrived at the “picture” of the first observable black hole. I’m going on memory, but they basically give all the data to several teams of astronomers around the world. They then crunch the numbers and arrive at what they think the data “looks” like. They do this in isolation. They then collate all the pictures and see where the similarities lie. They then debate for a bit, before arriving at a composite image that represents the black hole.

I’m probably getting that totally wrong. I was just amazed/embarrassed to find out that it’s not an actual photo-photo. Probably belongs on the thread about such things.

Sounds a lot like solving a blockchain but actually useful.

I’ll be honest here. You’re not alone.

Is there life on Mars?

No, there isn't

As the article says, it resembles a portal

Move on

Oh yes, there is an awful lot not only of image processing but image imagining going on to sharpen up the utter blur to a semi-resolved blur. The decision making on what should and shouldn't be included is also reliant on wisdom of crowds concept, which has had some spectacular experimental results suggesting it's efficacy.
