^nice technique!

Projected through my little 70mm scope, with mountains on the moon just visible

Best I can get with my wee Fuji and the heavy clouds up in Leeds.

Heh, I got the exact same image!

Fantastic!!

Brief period of sunshine up here in Edinburgh :)

beat you all

As before, I do enjoy this exoplanet stuff.

Hearing those dicks whooping and cheering sure made me feel good

I wouldn’t get in that thing even if they paid me the $28m fare.

This came to mind when Bezos exited the capsule

9 minute flight for a sub-orbital ballistic lob, not really that impressive

On its own maybe not, but fully reusable components? That's a step into the future

out of the two the virgin effort looks way more fun, proper buck rogers type spaceship rather than an elevator ride to the 11,987,237th floor

Last night's ISS pass just before 11 was a cracker

Is that you Bender?

But otherwise... Wow!

I suppose we're both fuelled by alcohol and both a bit bald, but the resemblances probably stop there!

Last night's show

Very impressive

What is the red dot/light at the start of this?

Ah, I have just worked out that it is the light on an airliner that I used as target practice just before the ISS appeared.

Anyone have any Perseid luck? "They" were expecting a late peak but spent an hour with a brew (1:30 - 2:30) and only counted 20 - I'm out in Hertfordshire with pretty good skies.

Spent half an hour outside at about midnight, under fairly dark Bucks skies (Milky Way and m31 clearly visible) and saw maybe 15.

Hello folks. I’m writing a sci-fi story for a competition, and I have a couple of astrophysics/ simulation theory queries that I’m hoping someone here can help me with (x-post from the AQA thread).

In my story, black holes are akin to USB ports onto which information from our Universe is being drawn, for eventual removal. It’s my understanding that the size of a black hole can be measured or approximated with the aptly named Schwarzchild radius. Is this radius on the event horizon? Does the size of a black hole impact the size of the singularity? Is the density of the singularity infinitely dense? Regarding white holes, is dark matter also theoretically expelled or is the energy+mass mix reconfigured in the wormhole?

Simulation theory and sci-fi-wise, has this idea been written about?
