Deep Space Object Search API

A FastAPI-based service for searching and retrieving information about deep space objects from various astronomical catalogs.

Data Overview

Our astronomical catalog includes data from multiple sources, processed and standardized for easy access. Here are some visualizations that showcase the scope and quality of our data:

Objects by Catalog

Distribution of objects across different astronomical catalogs

Sky Distribution

Spatial distribution of objects across the celestial sphere

Size Distribution

Range and distribution of object sizes within each catalog

Data Completeness

Completeness of different data fields across catalogs

Right Ascension Distribution

Distribution of objects across right ascension values

Data Processing

The data processing pipeline:

1. Downloads raw catalog data from VizieR
2. Processes and standardizes the data format
3. Validates coordinates and measurements
4. Generates processed CSV files ready for API use

Usage

The processed catalog files in data/processed/ are ready to use with the API:

• processed_messier.csv: Processed Messier catalog
• processed_ngc.csv: Processed NGC catalog

Each file contains standardized columns:

• name: Object identifier
• catalog: Source catalog
• ra: Right Ascension (J2000)
• dec: Declination (J2000)
• size: Angular size in arcminutes
