Webb Telescope Captures Stunning Image of Dusty, Dynamic Disc


James Webb Space Telescope (JWST) has been used to investigate dusty and dynamic discs around young stars. These discs, known as protoplanetary discs, are made up of gas and dust left over from the star's formation. They are also the birthplace of planets.

JWST's infrared vision allows it to see through the dust and gas in these discs, revealing the structure and composition of the disc, as well as the formation of planets.

Here are some examples of JWST's investigations of dusty and dynamic discs:

  • HH 30: JWST observed this edge-on protoplanetary disc, revealing the distribution of small dust grains and the presence of a high-velocity jet of gas. These observations help astronomers understand how dust evolves and how planets form.
  • NGC 346: JWST observed this star cluster, revealing dusty ribbons around young stars. These observations suggest that the conditions in NGC 346 may be similar to those in the early universe, when galaxies were forming stars at a furious pace.
  • Wolf-Rayet binary stars: JWST will be used to study dust-producing Wolf-Rayet binary stars. These stars are very hot and bright, and they produce large amounts of dust in a distinctive pinwheel pattern. JWST's observations will help astronomers understand the formation and chemical composition of this dust.

JWST's investigations of dusty and dynamic discs are helping astronomers to understand the formation of planets and the evolution of stars. These observations are also providing insights into the early universe.
