A bad, bad, bad Black Hole!

Post #1by ANDREA » 18.12.2007, 11:47

Here the NASA announce of a space drama, due to the jet of a supermassive Black Hole in the core of the 3C321 galaxy, hitting a smaller and very close (only 20.000 l.y.) galaxy:

It looks truly impressive, IMO. 8O
Moreover it's a very good example of scientific cooperation, being involved space and ground-based telescopes: NASA's Chandra X-ray Observatory, Hubble Space Telescope, Spitzer Space Telescope, the Very Large Array (VLA) in New Mexico, and the Multi-Element Radio Linked Interferometer Network (MERLIN) in the United Kingdom.

Just curious here...

What WOULD be the effects on a planet like the Earth in such a
galactic jet?

Good info on the Chandra web site :

I like especially this image :

Fridger, we don't have these galaxies in our database, don't we ?

I may be interested to add something in Celestia, to depict this scene.

And in this page of the Chandra site,
http://chandra.harvard.edu/photo/2007/3c321/index.html

together with many other movies and images, you can see this very nice movie, showing what happened to the Black Hole jet when entered in contact with the companion galaxy (6.8 MB):

Distance Estimate About 1.4 billion light years

I'm interested to create an addon to depict the scene in Celestia. I have all the tools and knowledge to create sprites. If only I was able to render them on my Mac ImageImage

Other animations there :

One of the first addons I tried was an active nucleus black hole. The 16000 LY limitation made it impossible.

In the case of 3c321, we don't need to represent the black hole itself. Just the galaxy and its satellite, and jets (with their extremities). I'll try to do something in end-january, since I don't have time to start the project right now.

Amusingly, I asked this very question just a few days ago... what a coincidence eh?

Hmm... Steinn Sigur?°sson at Dynamics of Cats suggests that the effects on a planet's atmosphere may be minimal.

Just plonk a zone plate in the path and focus the x-rays onto the target- it would do some damage then.
