# Visualisation of Multi-mission Astronomical Data with ESASky

## TL;DR

ESASky is a user-friendly web portal that enables scientists and the public to explore and visualize multi-wavelength astronomical data from various space missions and catalogs efficiently and intuitively.

## Contribution

This paper introduces ESASky, a novel web application that simplifies access and visualization of multi-mission astronomical data without requiring prior mission-specific knowledge.

## Key findings

- Supports visualization of sky in multiple wavelengths
- Provides summaries of query results and observations
- Maximizes responsiveness and usability

## Abstract

ESASky is a science-driven discovery portal to explore the multi-wavelength sky and visualise and access multiple astronomical archive holdings. The tool is a web application that requires no prior knowledge of any of the missions involved and gives users world-wide simplified access to the highest-level science data products from multiple astronomical space-based astronomy missions plus a number of ESA source catalogues. The first public release of ESASky features interfaces for the visualisation of the sky in multiple wavelengths, the visualisation of query results summaries, and the visualisation of observations and catalogue sources for single and multiple targets. This paper describes these features within ESASky, developed to address use cases from the scientific community. The decisions regarding the visualisation of large amounts of data and the technologies used were made in order to maximise the responsiveness of the application and to keep the tool as useful and intuitive as possible.
