Look up And Wonder
11th Jul. 2011 :: M51 Supernova SN2011dh

So, it would appear that something rather wonderful has happened.

Completely unknown to me a supernova was discovered in M51 on the 31st May/ 1st June this year, and it is clearly visible in my image of a couple of nights ago. Here is an APOD image. So, it seems that I have accidentally taken my first image of a Supernova! It has been designated the wonderful name: SN2011dh. The supernova is clearly visible in my image, as marked in red below:

Here is an image flip between my earlier effort and the latest:
(The apparent movement of some stars and the galaxy itself, is just an artefact of the image's orientation, quality and processing there is no actual movement).

Here is some more discussion.

About Me

I am an amateur astronomer; I am interested in science, innovation, astronomy and general musing about philosophies of life, the universe and our place in it.

I love to look up and wonder, and this blog is mostly what results from that wondering.

I also enjoy Paragliding.
