Euclid Telescope Unveils 2,674 New Dwarf Galaxies, Revolutionizing Cosmic Understanding
March 24, 2025
The Euclid Space Telescope, launched in July 2023, aims to catalog dwarf galaxies and enhance our understanding of the universe.
In a significant breakthrough, Euclid has discovered 2,674 new dwarf galaxies, advancing our knowledge of galaxy formation and evolution.
This discovery is particularly noteworthy given the challenges of observing dwarf galaxies due to their faintness.
Dwarf galaxies, which typically contain a few billion stars, are essential for studying the early stages of galaxy development and often orbit larger galaxies like the Milky Way.
The research team categorized the newly identified dwarf galaxies, finding that 58% are elliptical, 42% are irregular, and only 1% are rich in globular clusters.
Among these dwarf galaxies, approximately 4% contained a galactic nucleus, while nearly 7% were classified as Blue Compact Dwarfs, known for their high star formation rates.
Led by researchers from the University of Innsbruck, the study utilized data from 25 images captured by Euclid, providing unprecedented depth and spatial resolution.
A pre-peer-reviewed version of the research is available on the arXiv repository, showcasing ongoing scientific collaboration and transparency.
