Dense gas blocks starlight, creating unusual shadows. A new study shows how these shadows affect hydrogen and carbon in space.
Scientists discover how shadows change the chemistry of star-forming clouds
Shadows may play a much bigger role in the birth of stars than scientists previously understood. A new computer model shows that shadows inside enormous clouds of gas and dust can change chemical reactions and help explain patterns seen by powerful space telescopes. Stars are born inside huge clouds of cold gas and dust in […]
Hidden shadows in stellar nurseries reveal how stars reshape cosmic chemistry
A high-resolution 3D model of the Orion Bar reveals how dense gas clouds shield molecules from stellar radiation, shaping chemical reactions and structures observed by the James Webb Space Telescope.
Cosmic shadow games: The light of young stars changes the molecules in the clouds from which other stars emerge. A three-dimensional model of a gas cloud modelled on the Orion bar now shows how dense areas shield radiation and deform chemical interfaces. This could explain why the James Weber space telescope sees arcs and thread-like structures there that can hardly reproduce simple models. Duisburg [...] The article James-Webb shows how gas lum…
