ESA's Euclid Mission Captures Highest Resolution Image of Milky Way's Galactic Center
By
Kate Mothes
Summary
In March 2025, the ESA's Euclid mission captured the highest resolution image ever taken of the dense, glowing center of the Milky Way galaxy. The image reveals a massive swarm of stars forming a bulge at the galaxy's heart, composed mainly of old, cooler stars giving it a characteristic yellow hue. Scientists are using this data to search for exoplanets through microlensing, a technique that monitors tiny changes in starlight over time to pinpoint exoplanets and measure their mass.
