Science Plenty of really hot things exist in the universe. But do we know of fire anywhere besides on our planet?
Robotic Spaceflight Why doesn’t NASA reuse space probe designs from successful missions like Cassini, New Horizons, and the Mars rovers? Using the same design and tweaking for landing on different planets or orbiting them would seemingly make the entire endeavor cheaper.
Deep-Sky Objects Since the discovery of the “Pillars of Creation,” what changes have occurred within them and the surrounding area?

Astronomy for beginners, Observing Basics Why do the constellations and the Moon appear upside down from the Southern Hemisphere?
