Why a Tent on Mars Beats a Full-Blown Planetary Makeover
Today's Martian surface is a cold, nearly airless home. Many dream of a full renovation: warming the planet, filling it with air from carbon dioxide and nitrogen.
Life from Mars: How Realistic Is It?
A rock knocked off one planet by an asteroid impact hurtles through space and lands on another. If microbial spores are hiding inside, they might survive the cold, the radiation, and the rough landing. That's panspermia — the idea that life travels between worlds. But imagining such a journey is one thing; calculating every step is quite another.
A Swarm of Tiny Sails Heads to Proxima b
A handful of coins accelerates to one-fifth the speed of light. That's what Coracle interstellar probes will be like — tiny spacecraft weighing just a few grams, each with an ultrathin sail film. A powerful laser beam pushes them forward: light presses on the sail like wind fills a yacht's sails, except instead of air, it's a stream of photons.
Cosmic Tuning Fork: Earth and Moon Resonate with Gravitational Waves
In the cosmic silence, between the whisper of the relic radiation and the roar of black hole mergers, a hidden symphony plays.
A Sun-Sized Lens Searches for Life Around Distant Stars
The Sun is not just a source of heat; it's also the largest lens in the solar system. Its gravity bends light rays like glass, focusing them into a bright ring far beyond Pluto's orbit. If light from a distant planet enters this ring, astronomers could reconstruct its portrait — not a point, but a map with surface details.
