Millions of stars. Thousands of hidden worlds. One unprecedented view of our galaxy.
Three years since launch, ESA’s Euclid space telescope reveals the Milky Way galaxy’s centre in extraordinary detail: a mosaic of tens of millions of stars captured in just 26 hours.
But this is more than an image. It is a map of stellar evolution, from dark clouds where stars are being born to ancient populations packed into the galactic bulge.
And hidden within this dense field of light are planets we cannot see directly.
Through gravitational microlensing, astronomers detect distant worlds by measuring tiny, temporary changes in light as stars pass in front of one another, revealing planets and even their masses through gravity alone.
Euclid, originally built to explore dark matter and dark energy, is now helping open a new window on our own galaxy, and the unseen worlds within it.
