What are M42 lenses?

Hi, Everyone I ask tells me that canon is better for astrophotography because of it's 3rd party software support, but I don't understand when this comes in handy. Can someone give me real examples where canon comes on top of nikon because of it's software support? I'm having doubts about buying Canon over Nikon because every review on the net concludes that nikon has way better low light performance and can handle higher ISO better than Canon. This would make it better choice for astrophotography, but every astrophographer recommends Canon. What am I suppose to buy now??
