ESASky [1] is a web-based tool developed by the European Space Agency (ESA) to provide access to astronomical data.
It aims to offer a user-friendly interface for exploring various datasets, including images, catalogues, and spectra, collected from ESA missions like Planck, Herschel, Gaia, HST, XMM-Newton, and INTEGRAL, among others.
[citation needed] ESASky is also designed to facilitate data exploration by allowing users to overlay footprints of different datasets, providing a comprehensive view of multiwavelength observations for specific celestial sources or regions of interest.
This feature enables researchers to analyze data from various missions and projects simultaneously, enhancing their ability to study astrophysical phenomena comprehensively.
It is intended to streamline the process of accessing astronomical data, aiming to reduce the need to navigate through individual mission archives.
