Illustration of 19 spiral galaxies observed with the James Webb Telescope in the near- and mid-infrared light range. The near-infrared camera captured millions of stars in these images. Older stars appear blue and are clustered in the galaxies’ cores. The observations in the telescope’s mid-infrared range highlight glowing dust, showing where it exists around and between stars, appearing in shades of red and orange. Stars that haven’t yet fully formed and are encased in gas and dust appear bright red.

Heidelberg University astrophysicist vital contributor to preparation and study of new data

Fascinating new images from NASA’s James Webb Space Telescope show the structure of 19 nearby spiral galaxies. They were acquired with infrared light and provide a detailed view of the distribution of stars and the material from which they form. An astrophysicist from the Centre for Astronomy of Heidelberg University (ZAH) made significant contributions to the latest publication: Dr Oleg Egorov is one of the main developers of the data reduction software used to convert the observations from the space telescope into images. The researcher also uses the data for his own research. ...
