Wonders of the Universe

One thing that wasn't clear in the last episode... It was suggested if/when Betelgeuse went supernova, we'd have an object about as bright as a full moon in our sky.

But for how long? How long would that immense light last for, and how quickly would it die down? Would it be (super) bright for just a few hours for example?

Was looking forward to it myself but like a few others.. I've found it a touch boring. He does get to go to some nice locations though.

I did laugh:-

Trip to the US + drive in mustang convertible = just to blow some soap bubbles :D
 
Yeah, it's bizarre some of the things they gave going on in the background while he's basically giving us a physics lecture. Still, it grabs my interest so I'm not complaining.

Him randomly playing the piano was a bit too much though. "Hey, look what else I can do!"
 
I actually find this to be a brilliant sleep aid, still not found one better actually. Put it on my phone and try to watch it in bed. I don't find it boring, the exact opposite. I find it so fascinating I'm hit with the age old problem of the only time you need to stay awake the only thing you can do is sleep :D It's great.

Hmmm I might try that. Through iPlayer I take it?

Currently my sleep aid is to read a book on my phone (with the background black and text white). I'm normally struggling to keep my eyes open after about 15 minutes.

Would be a few days.

Im also a bit annoyed be kept calling it Bettlejuice, call it by its proper name you moron.

Betelgeuse is the most interesting thing in the night sky imo. You can see a Red Giant 600 ly away with the naked eye and it might not even be there anymore. If it was to go supernova in my lifetime I think I would consider myself the luckiest Human to witness it.

It sure would be an awe inspiring event if it did go supernova someday - to look up at night and have the chance to see something of such celestial majesty would be a real honour!

To think it's doing the things described and yet it would look so serene and peaceful to the casual observer!

/awesome video there by the way - was it actually posted by the BBC or is that a faked upload?

The star's unusual name inspired the 1988 film Beetlejuice, and script writer Michael McDowell was impressed at how many people made the connection.

I can find at least 5 astronomy sites that also call it beetlejuice.
 
Old biddies have been complaining that the music was too loud and they struggled to understand the speech, so you should notice a relatively quieter audio track for future installments. Bless.
