Scientists have discovered the strongest evidence yet of a rocky planet with an atmosphere outside the solar system, challenging previous notions that small planets that orbit closely to their stars are unable to sustain a thick blanket of gases. TOI-561 b orbits a 10-billion-year-old star located about 280 light-years from Earth and has a vast […]
New Life-Giving Molecules Found in 17-Year-Old Data From Saturn’s Moon Enceladus
The south pole of Enceladus—a tiny moon orbiting Saturn—is a volatile place. In this region, the moon’s subsurface ocean spews jets of water through four “tiger stripe” cracks in the icy crust, culminating in a single plume of ice particles that stretches hundreds of miles into space. The Cassini spacecraft spent two decades studying these […]
