A new ultra-low reflection substance has been developed for use in space telescopes. Apparently it is 10-20 times less reflective than matt black paint.

 

"It's the blackest surface commercially available," [Dr Richard Brown] told BBC News Online. "It's a very interesting surface to look at because it's so black." Well duh.

 

The coating is made of an alloy of nickel and phosphorus pitted with tiny curved craters which absorb light.

I wonder how long before I can get this as the color of my car...

Lots of applications for it in the future in solar heating if it's cheap. Maybe a coating on the back of a solar sail. It sounds pretty useful when they get the cost down.
