Webb and Hubble release images of a stellar nursery, a galaxy cluster and a nebula
Webb imaged the NGC 7129 stellar nursery and a galaxy cluster, while Hubble imaged an out-of-sync galaxy and a nebula.
Teams using the James Webb Space Telescope and the Hubble Space Telescope have released several new images. Webb's show a stellar nursery and a galaxy cluster. Hubble's show an out-of-sync galaxy and a bubble-like nebula. Both telescopes are jointly operated by NASA and the European Space Agency, and the Canadian Space Agency also participates in Webb.
The Webb image of the stellar nursery NGC 7129 covers a region 3,300 light-years from Earth. Its dust clouds help start the formation of stars but also block the light from young stars at optical wavelengths. Webb's infrared sensitivity lets its instruments see through the dust and reveal hundreds of stars at different stages of their lives.
The most massive star in NGC 7129 is LkHα 234, at the centre of the region. It is five to eight times more massive than the Sun, and it is a pre-main-sequence star that has gathered all the mass it needs and is contracting under its own gravity.
