Supernova in the Big Dipper
There is apparently a Supernova that's appeared in the handle of the "Big Dipper". Large binoculars or good sized scope should show it. I tried seeing it last night but it was obscured by streetlights, pollution and clouds. Hopefully I'll have better luck tonight as I saw the last one that occurred 25 years ago when I was still living in South Africa so it'll be cool to see this one as well if I can. Though at Magnitude 10 it looks like I might not be lucky this time around. Pity.

Cool! (or I should say, Hawt!)
Hopefully somebody will swing Hubble around for snapshot. |
Wow, thanks for the heads up. I might try my 150mm camera lens + 2x adapter (300mm) to see what's up.

If I am understanding this correctly a light year is the distance it takes light to travel in one year. Since this is 21 million light years away, this supernova occurred 21 million years ago?
Hard to wrap your head around numbers like that. |

It's cloudy tonight, maybe tomorrow I could get a peek. How long should this last?
|
I believe I read peak viewing will be from 9-12 Sep.

Well I tried looking for it tonight but no luck despite clear skies. Mag 10 is below naked eye visibility and even with my 4.5 inch scope I couldn't even find the galaxy it's in. I think the light polution is just too much at my house. Might try again next couple of nights though and hope I get lucky.

Still cloudy tonight. Bummer.
|
Haven't had a clear night here in....probably a few weeks at this point! I'll have to resort to interwebs pictures from hubble and whatnot
|
Out of curiosity, how does one "see" a black hole?
|
By calculating the gravitational force generated by that point. Since we can see things around it being drawn to it we can calculate those masses by terms of other gravity forces, spectrography, and some other calculations...calculate the speed and centripetal force and voila! Mathematically we can show black holes exist as well, through some serious physics.
|
yeah, but these guys are talking about seeing it with a pair of binoculars...
