Welcome to the Jafar gallery ! It showcases some beautiful images taken by the Euclid space telescope. Select a type of object to discover more about them, or simply admire them all.

This is a subsample of galaxies within the Euclid Q1 data that display prominent tidal features. These extended structures are stars expelled from their galaxies due to the gravitational forces occurring during galaxy mergers. Tidal features are therefore great probes of recent or on-going galaxy mergers, and help us unravel the mass assembly of galaxies. The images illustrate the amazing details revealed by the Euclid space telescope, that will enable the study of faint, low surface brightness (LSB) features over thousands of square degrees on the sky. A detailed analysis of these systems will be presented in a future paper.

Dwarf galaxies are the most common type of galaxy in the Universe. Despite their small size, they are believed to be the building blocks of larger galaxies. Studying their properties and abundance offers valuable insights into the cosmological history of our Universe. Dwarf galaxies in the nearby Universe are particularly important to investigate, a task now made possible with surveys like Euclid. Below, we showcase examples of dwarf galaxies with elliptical shapes, some of which also exhibit a bright central nucleus — a dense concentration of stars at their core.
