Wordless Wednesday – Supernovae

by Deb on August 31, 2011

Supernova remnants

To continue from Monday’s post, pretty pictures!

Cassiopeia above was a Type II supernova, that white spot in the middle is the remaining neutron star and the outer layers are the material that was blasted away by the explosion.

sn1006c is about a thousand years old.

The other three were all Type Ia supernovae, like the M101 explosion we are seeing now. They were all observed with the naked eye.

kepler

Kepler is around 400 years old.

These are not pure optical images, they are combinations from different NASA observatories showing optical and x-ray information. The colours indicate either energy or the type of elements that have been blasted out.

Tycho was observed in 1572.

What amazing images! 🙂

I brought up the topic of the diamond planet at dinner last night, thinking I might sound clever, and it seems my husband had already seen it 🙁 Oh well, next time!

Love the name Tycho, they use it for a dog in the kids Planetarium presentation in Melbourne. We have a stuffed version on Miss 4’s bed, she loved the show that much.

The diamond planet has been everywhere, I think it’s irresistible. That’s why I tried to give a bit of an explanation of how it happened, to make my take a bit different.

Tycho Brahe was a great scientist, the last of the naked eye astronomers. Kepler was his assistant and worked out the laws of planetary motion using Tycho’s observations. There are lots of astronomical things named after him, including craters and stars as well as the supernova.

The colours are quite incredible. I love that you’re sharing this. I’m learning so much from your blog. (Science was never my strong point at school!) 🙂

I wish I knew more about space – Im pretty sure my sons know more about it than me! I think Stephen Hawking and I need to spend some quality time together in my living room 🙂 Happy WW!
