Cosmology What if there were two gravitational wave sources coming from different directions? Would there be an interference pattern?
Telescopes and Equipment I am struggling to find a system for telescopic observations of the planets and their major moons worthy of photographing. One wrinkle: I am in a wheelchair and almost blind.
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?
The Moon Why does the daily moonrise time vary by as much as 60 minutes, and as little as 30 minutes during the same month?
Cosmology, Science Why are gravity and quantum mechanics incompatible with each other? Why can’t they be combined into a single formula or concept?
