Along with the brown dwarfs of IC 348 (which are relatively nearby) or the closest Uranus, James Webb Space Telescope One was observed in early December Supernova Which is located in a galaxy far, far away. This survey was made possible by Gravitational lens Resulting in the signal being amplified while distorting the image. the Gravity lenses They are essential for scientists, allowing them to observe phenomena that would otherwise be too faint even for powerful instruments such as… JWST.

In particular, this phenomenon became possible thanks to a large group of galaxies called galaxies Macintosh J0138.0-2155. The galaxy that was observed thanks to Gravitational lens Takes a name MRG-M0138 It is located 10 billion light-years from Earth (at a time when the universe was relatively still “young man”).
The peculiarity of this galaxy is that in 2019, a supernova explosion was observed in images taken by the Hubble Space Telescope three years ago. In the case of the HST, 105W and F160W filters were used. The synergy between multiple telescopes (ground-based or space-based) is certainly one of the strengths of having instruments that can detect at different wavelengths but also at different times, taking advantage of the fact that Hubble has now been in orbit for many years (which helps) as scientists do who work with the web).
