Supernova remnants

[Tricky Dicky]

Don't know why, bit thought I'd share NASAs image of the day.

Amazing to think this supernova occurred before the Egyptians built the pyramids and is still expanding ....

It is a subject that if you allow it to can fascinate....time and space are truly an awesome phenomenon-thanks for sharing.

De nada - I follow NASA on twitter and always look at the image of the day. I love the subject of Astronomy and astro-physics - not that I know too much about it.

So much out there that it's frightening,when then pointed Hubble at a previously thought of quiet,dark area of space,what did they see? An area of Galaxies literately colliding into each other..

The numbers and distances involved are truly mind-boggling. Imagine if Betelegeuse goes supernova in our lifetime - and it could do so at any time - it will be easily visible during the daytime.

I'm no expert either,but that's a Red giant i think? that would be quite something especially if we see something in our daily skies other than the Moon and the Sun.

Perhaps it already has,we just can't see it yet..

640 light years away, so possibly.

That's not far at all,in the grand scheme of things it's practically in our back garden so to speak

Me to, may I recommend if you haven't seen it "Beyond the Cosmos" on Discovery (I think, if not one of the 52x numbers on Sky). Most programmes on this subject I tend to find a bit dry (too many equations that us mere mortals can't understand) and very complicated, this tends to try and make a difficult subject a bit more easier. Last night it was multiverses and it was very interesting and mind boggling, if that is your thing.

Very nice. I fancy a trip to the observatory in Herstmonceux on Saturday, for an evening with the planets.

Sounds like fun - I have never looked at the sky through a proper telescope. I reckon I could spend a long time just looking at the moon.

Good call, just added. (I'm not much of a twitterer)

I can't put into words how amazing that would be. But I think it would be wrong to wish for the destruction of another star.

Scientists are wondering whether it could happen in our lifetime, but I assume what they really mean is, it could have happened 600 years ago, we're waiting to see.

Neither am I, but I now follow about 25 people, NASA was one of the first I added.

Me wanting to see it, isn't really going to affect it methinks (it's not personal) - it's going to (or has) happen anyway. Whether I'll be around to see it, is another matter.

It can be difficult to comprehend the vastness of it all.

I had to think carefully when venus and saturn were one above the other last week when all of the planet maps I have ever look at show they are either side of the earth

see something in our daily skies other than the Moon and the Sun...

night time as the mo you can see venus in the west with bigger, brighter saturn above it. In the east large red light is mars. Apart from venus I don't usually know where the other planets are, just lucky at the mo they are so prominent.

Why the dunce hat? That confuses the shit out of me.

I went 6 months ago, expecting them to see through the breaks in the cloud, but if it's cloudy they don't open up the scopes, as they won't risk them getting rained on - call first to check. The moon rises at about mid-day on Saturday, so you can get a good look before Jupiter appears in the night at about 7.30. I'm fascinated by it all, but as yet I've done very little to learn or see much.
