Summary
A 26-hour Euclid observation has produced the largest, most detailed visible-light image of the Milky Way’s center, resolving more than 60 million stars in the crowded galactic bulge.
That snapshot could sharply expand planet hunting by giving astronomers a clean baseline before stars overlap, improving microlensing measurements and helping confirm a planet’s existence and mass.
Dr Eamonn Kerins said the data could push the known exoplanet tally from about 6,000 to more than 100,000 across the galaxy, with measurement accuracy improved by up to a factor of three.
The €1 billion ESA telescope was launched in 2023 to map the cosmos and probe dark matter and dark energy, but researchers say its camera has proved unusually powerful for exoplanet work.
Nasa’s Nancy Grace Roman telescope, due to launch in August, is expected to find about 1,500 microlensing planets and another 100,000 transiting candidates, with Euclid data helping rule out false signals such as binary stars.
As two super-telescopes prepare to find 100,000 new planets, how will we decide which distant worlds could actually harbor life?
With telescopes creating overwhelming data, will AI become the primary discoverer of new planets and cosmic laws?
Could Euclid's data prove dark matter and energy are linked, rewriting our fundamental understanding of the entire universe?
Euclid’s Unmatched 26-Hour View of the Milky Way’s Core: Revolutionizing Exoplanet and Galactic Science
Overview
The European Space Agency's Euclid space telescope has delivered a groundbreaking image of the Milky Way's core, offering an unprecedented look at our galaxy's bustling heart. Thanks to its exceptionally sensitive visible light camera, Euclid can distinguish individual stars even in the dense galactic bulge without being overwhelmed by their combined light. This capability marks a significant milestone for galactic astronomy, providing the most detailed and expansive view of the Milky Way's center ever captured. The unique data from this large and remarkably sharp image opens new possibilities for scientific discovery and advances our understanding of the galaxy.
