Figure 3: This plot shows the faintest flux of light emitted by a point source that different telescopes can detect, by wavelength. It's measured over 10,000 seconds at a signal-to-noise ratio of 10. On the left axis, flux is given in units of Jansky, where 1 Jy = 10^-26 Watts per area per wavelength. On the right, flux is given by AB magnitude. Note that two JWST instruments are shown, NIRCam and MIRI, that operate over different wavelengths (red lines). Credit: Space Telescope Science Institute.⁵
