Webb Reveals Rich Composition of Interstellar Molecular Cloud Ices

NASA's James Webb Space Telescope finds signs of 'building blocks for life' in icy clouds | Science & Tech News

Darkest view ever of interstellar ice

Fires in a microgravity environment (like the space station) are fed by random oxygen molecules stumbling into them in a process called molecular diffusion. This produces spherical flames that burn more slowly and consume less oxygen, giving off a fraction of the heat emitted by terrestrial flames.
