An inset or zoomed-in plot in astronomy is used to highlight a specific region of interest within a larger dataset, image, or graph. It helps show finer details that may not be visible in the main plot. Here’s how it works:

How It Works:
Main Plot: Displays the overall view, such as a full galaxy, sky survey, or spectrum.
Inset (Zoomed-in Region): Focuses on a specific part, like a star-forming region, a black hole’s vicinity, or detailed spectral lines.
Connection (Optional): A box or arrow marks the region in the main plot that is being zoomed in.
Common Uses in Astronomy:
Galaxy Studies:

Main plot: Entire galaxy.
Inset: A zoomed-in view of the central supermassive black hole region.
Spectroscopy:

Main plot: Full spectral range.
Inset: A zoomed-in section showing a key emission/absorption line in detail.
Cosmology:

Main plot: Large-scale structure of the universe.
Inset: A small section showing a galaxy cluster or cosmic filament.
Exoplanet Transits:

Main plot: Full light curve of a star.
Inset: A zoom-in on the dip in brightness when a planet transits.
