MissionsTesla’s new Roadster flew over its own lineup on cold-gas thrusters borrowed from orbital flight. Here’s what the hover demo proved, and what it didn’t.
Black Holes & SingularitiesSwap the Sun for a black hole of the same mass and Earth’s orbit wouldn’t twitch, but with the light gone, our planet would freeze solid within months.
Terraforming & Sci-TechFrom super-greenhouse gases to an artificial magnetosphere, here is the actual engineering sequence scientists have proposed to make Mars habitable, and how long each step would take.
Cosmic MysteriesIn 1960, Freeman Dyson described how to find giant alien civilizations: look for the waste heat of star-sized machines. Sixty-six years later, astronomers are still looking, and the hunt just got interesting.
Black Holes & SingularitiesFrom the 4-million-solar-mass heart of our galaxy to a 100-billion-solar-mass monster that strains physics itself, a tour of the heavyweight champions of the cosmos.
