Astronomers have observed directly for the first time how intense light from stars can ‘push’ matter. Researchers made the observation when tracking a giant plume of dust generated by the violent interactions between two massive stars.
The results, made using infrared images of the binary star system WR140 taken over 16 years, are reported in the journal Nature.
In a complementary study of WR140, published in Nature Astronomy, NASA’s James Webb Space Telescope (JWST) was able to see much deeper to snap an image of not just a single accelerating dust plume, but almost 20 of them, nested inside each other like a giant set of onion skins.
WR140 is compri...
