![[Left]: A concept raytrace showing the IFS, with just the FUV channels shown. The NUV channels take the zero-order from each FUV grating and reflect it towards the IFS fold mirror (on either side) into a similar format NUV IFS (see Haughton et al., 2026 for a depiction of the INFUSE design that this IFS is based on13). The IFS assembly is forward (out of the page) from the MOS at the focal plane, with the IFS fold mirror canted slightly to move the slicer, gratings, and detectors over 0.7 meters from the MOS optical path. [Right]: The slicer-based IFS operates by reflecting portions of the image plane to different gratings, which then focus a spectrogram to a unique portion of the detector. In essence, each reflective slice operates like a long-slit spectrograph, with the slicer geometry separating the multi-slit spectrograph to avoid spectral confusion.-- astro-ph.IM](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/An-Ultraviolet.png?resize=1200%2C563&ssl=1)

![Architecture and workflow of AstroGenesis. Researchers interact with the system through a chatbot interface and select an appropriate DSRM corresponding to the astrophysical source class under investigation. Within the selected DSRM, a Supervisor Agent coordinates task execution through a Planner/Replanner and a set of specialized agents responsible for literature analysis, observational data retrieval, theoretical modeling, and research ideation. These agents operate using external tools which include, astrophysical tools, data-analysis modules, and pre-trained models to perform modeling of the data, etc. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/AstroGenesis.png?resize=1200%2C722&ssl=1)

![First detection of fully deuterated methanol in interstellar space This composite image shows the Perseus molecular cloud, which is located about 1,000 light-years from Earth. A rare form of the organic alcohol methanol has been observed around at least one of the very young stars still embedded within it. This is the first time this molecule has been detected in space, as shared by the ALMA COMPASS Large Program (Complex Organic Molecules in Protostars with ALMA Spectral Surveys).
