Simeis 147 in Taurus

[prokyon]

Hi folks,

done 2 weeks ago. I was always fascinated by this supernova remnant in Taurus. It is huge ( diameter is 6 full moons!) but very weak.

Just for fun I tried to give some colour. :rolleyes:

Impressive Werner! Certainly one to put on the list. :thumbsup:

[h0ughy]

lots of structure in that shot

Fantastic Ha shot Werner.

Nice rendition of a not all that often imaged object:):)

[strongmanmike]

Yes, an excellent result, the filaments a so thin, fascinating object huh?

A great image of a terrific object.

Wow, thats beautiful Werner!! :thumbsup:
Bit out of visual range for my 10", great image to image.


Some info here, and includes - very large SNR in Taurus that occurred 30,000 years ago, covering 3 dg of sky. lar that is expanding at a rate of 1000 kilometers/second

Philip Harringtons new book 'Cosmic Challenges' (which I have) also has some info -

Simeis 147 is a very faint, very large supernova remnant in Taurus that is expanding at a rate of 1000 kilometers/second. It covers an area of over 3 degrees of sky and is just barely included in this two frame mosaic using the STL11K in combination with the FSQ106 scope. Simeis 147 is a result of a supernova explosion that occurred approximately 30,000 years ago, and the remaining pulsar has supernova results from a massive star (at least 8 solar masses) that has used up most of its elements through fusion, converting hydrogen to helium, oxygen, silicon, sulfur, calcium, gold, and eventually iron. Iron is not a viable fuel for fusion (it requires too much energy), meaning that this element represents the end of the line for a dying star. Without the outward force of fusion-induced radiation, the star collapses under its own gravity, resulting in a massive explosion and release of radiation, some of which we see as visible light. The stellar remnant of a supernova explosion is a neutron star or a black hole (depending upon the size of the residual star). If the residual star is between 1.44 and 3 solar masses, it forms a neutron star (which is also known as a pulsar, as is the case for Simeis 147). If it is greater than 3 solar masses, it forms a black hole.
