NASA’s Webb Redefines Dividing Line Between Planets, Stars

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way. Astronomers used NASA’s James Webb Space Telescope to examine 29 Cygni b, an object […]

Nutrition Research Arrives Aboard Space Station

No matter how far humanity aims to travel or how ambitious the mission, nutrition will play a key role for the crew members on distant worlds. Before planning long-term stays on the Moon, Mars, and beyond, humans must learn to grow and care for plants and other sources of nutrition like algae to keep the […]
