IC 4970 and NGC 6872

This composite image of data from three different telescopes shows an ongoing collision between two galaxies, NGC 6872 and IC 4970 (roll your mouse over the image above). X-ray data from NASA's Chandra X-ray Observatory is shown in purple, while Spitzer Space Telescope's infrared data is red and optical data from ESO's Very Large Telescope (VLT) is colored red, green and blue.

Astronomers think that supermassive black holes exist at the center of most galaxies. Not only do the galaxies and black holes seem to co-exist, they are apparently inextricably linked in their evolution. To better understand this symbiotic relationship, scientists have turned to rapidly growing black holes - so-called active galactic nucleus (AGN) - to study how they are affected by their galactic environments.

Black Holes

A nice photo but it is still an assumption that black holes exist. No proof! In theory but that is all it is, a theory. Figures can be manipulated to make maths prove anything!

Galaxy Collision Switches on Black Hole

While IC 4970's black hole gets revved up by this interaction, the nucleus of the larger galaxy NGC 6872 shows no signs of current star formation or nuclear activity. But for how long?

It's a matter of time

That's a good question - it's just a matter of time, though that may be millions of years!


Now this is highly recommended post for me. I will surely email this to my friend.

Nice work! Your post is an
