I bought a new digital camera a few weeks ago, and I was very impressed by its resolution - a whopping10 Mpx! (10 million pixels). But that is tiny compared to the digital camera involved in the University of Hawaii's Pan-STARRS project...

Their digital camera is a staggering 1,400 Mpx!

I would have to buy another 139 cameras to compete with that!

Pan-STARRS main aim is to repeatedly photograph the sky looking for potentially hazardous asteroids - we only know of 953 PHA's at the moment...
