An example target in a Webb cycle 1 program using this mode: the Hubble Ultra-Deep Field.Ģ. This mode will be used for almost all aspects of Webb science, from deep fields to galaxies, star-forming regions to planets in our own solar system. Near-infrared imaging will take pictures in part of the visible to near-infrared light, 0.6 to 5.0 micrometers wavelength. The detailed list of peer-reviewed observations planned for the first year of science with Webb ranges from our solar system to the most distant galaxies.ġ. These are just examples each mode will be used for many targets, and most of Webb’s science targets will be observed with more than one instrument and/or mode. Some of the modes won’t be verified until the very end of commissioning.įor each mode we have also selected a representative example science target that will be observed in the first year of Webb science. Each mode has a set of observations and analysis that need to be verified, and it is important to note that the team does not plan to complete them in the order listed below. In this post we’ll describe the 17 modes, and readers are encouraged to follow along as the Webb team checks them off one by one on the Where is Webb tracker. Once we have approved all 17 of these modes, NASA’s James Webb Space Telescope will be ready to begin scientific operations! There are 17 different instrument “modes” to check out on our way to getting ready for the start of science this summer. With the telescope optics and instruments aligned, the Webb team is now commissioning the observatory’s four powerful science instruments.
