Maybe it shows the Star Wars Galaxy being acquired by the Disney galaxy?
You saw it on El Reg first!!
The European Space Agency's Herschel Space Observatory has beamed home pictures of two galaxies inexorably moving towards each other and boffins offered simulations of what happens next. The galaxies concerned are known as HXMM01, the name given to a bright spot in the sky. Closer examination of HXMM01 tells us it is very old …
Probably the same as the unofficial rule of the road:
Give way to whoever's biggest.
You can argue about whether a car had priority until you're blue in the face. The fact is that if you pull out in front of bus/lorry then you'll be lucky to be having the argument at all. Which is why I'm always astounded that motorbikes take such risks.
Avoid having the accident. Then it doesn't matter whose fault it was. :-)
It's quite remarkable just how many galaxies are merging in the distant universe. The IR data from Herschel makes them really easy to spot, because all the dust gets heated by merger-induced star formation. ~20% of galaxies that have IR signatures are merging, which results in some really nice images in the optical region from Hubble.
