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.
Cosmic MysteriesThe galaxy should be crawling with civilizations. Seventy-five years after Enrico Fermi asked the question over lunch, the silence is still deafening — and the possible answers keep getting stranger.
MissionsA gram-scale chip riding a laser-pushed sail could reach another star system in twenty years. The physics checks out — the engineering is the adventure.
Black Holes & SingularitiesPast the event horizon, our best theories collapse into contradiction. Firewalls, fuzzballs, and wormholes — a tour of physics’ most guarded secret.
Astronomy Picture of the Day
Towering columns of cool interstellar gas and dust in the Eagle Nebula glow in this near-infrared view. New stars forming inside the pillars appear as bright red orbs at their tips.
