Tools & Capabilities Breakdown

Astronomy Oracle Tools (3)

lookup_object

Look up a celestial object by Messier number (e.g. M31), NGC/IC designation (e.g. NGC7000), or common name (e.g. Andromeda Galaxy). Optionally compute visibility from a given location and time.

search_objects

Search and filter the celestial object catalog by type, constellation, magnitude, angular size, or catalog membership. Returns a formatted table of matching objects sorted by brightness.

plan_session

Generate an observing session plan for a given location and date. Returns the best celestial objects to observe grouped by time window (evening, midnight, pre-dawn), scored by observability.

Nasa Cmr Tools (3)

search_collections

Search NASA's Common Metadata Repository for Earth-science dataset collections by keyword, platform (satellite/mission), instrument, time range, or bounding box. ~10k collections covering MODIS, Landsat, Sentinel, VIIRS, GPM, and every NASA DAAC. Sorted by usage. Keyless.
