The James Webb Space Telescope, which was sent into space in December 2021 and officially began operations in the early weeks of the summer of 2022, emerged today with another major sighting. scientists in space dust particles repelled by ‘light’ managed to observe.

The observation in question was made in a system called WR 140, where two stars orbit each other. The system is emitted from the same stars, along with the charged particle winds from the stars. radiation irradiation It contains nested layers of dust that are pushed by. In the new observation, the moments when these layers of dust are pushed are clearly visible.

WR 140 as seen by James Webb:

With this observation, scientists for the first time in history succeeded in detecting this radiation-induced pressure. Speaking of his achievements, the astronomer Yinuo Han told how the observation was possible:

“It’s hard to see that starlight causes acceleration because the force decreases with distance and other forces take over. To make the acceleration measurable, the material must be reasonably close to the star or the radiation pressure source must be extra strong.”

The two stars in the WR 140 continuously work together as follows:
