I have a couple of 3D printed items at home & love seeing how CSIRO helps cancer patients with world-first surgical innovations. At present I'm in it for dice & boxes, but you never know. Maybe one day I'll have titanium ribs!
Just how dim is the sunlight on Pluto, some three billion miles away? This artist's concept of the frosty surface of Pluto with Charon and our sun as backdrops illustrates that while sunlight is much weaker than it is here on Earth, it isn't as dark as you might expect. In fact, you could read a book on the surface of Pluto. Image credit NASA/Southwest Research Institute/Alex Parker
