Dwarf Galaxy Caught Ramming Into a Large Spiral Galaxy


www.nasa.gov said:

Observations with NASA’s Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth.   The hot gas cloud is likely caused by a collision between a dwarf galaxy and a much larger galaxy called NGC 1232.  If confirmed, this discovery would mark the first time such a collision has been detected only in X-rays, and could have implications for understanding how galaxies grow through similar collisions.

Multi-Million degree gas?... Wow! Doesn't bode well for any planets that might have been in the area!

Oh dear, i hope no one was hurt. :(

Life is a hideous business, and from the background behind what we know of it peer daemoniacal hints of truth which make it sometimes a thousandfold more hideous.

It is important to distinguish between temperature and heat energy, they are not the same thing. As an example imagine a candle and a radiator in the same room. The candle flame is at a much higher temperature than the radiator but will never make the room warm as it does not give out enough heat.

The gas may be at millions of degrees, but if (as gas in space often is) it is extremely tenuous then it may not radiate enough heat energy to do much damage.

You are not the first to comment on this. I'm in disguise ;)

Actually it is my original avatar and the one I use everywhere else, so I decided to go back to it here too.

I would like some of that gas to heat my house this coming winter.
