Europe's Euclid Space Telescope Blasts Off On Quest To Illuminate Dark Universe

The European Space Agency launched its Euclid space telescope to explore dark energy and dark matter, which make up 95% of the universe.
After a monthlong journey, Euclid will survey galaxies as far as 10 billion light-years away to create the largest 3D map of the cosmos.
Equipped with an infrared telescope and spectrometer, Euclid will study the distribution of dark matter between galaxies using gravitational lensing.
By measuring distances between galaxies, Euclid aims to understand the accelerating expansion of the universe driven by the mysterious dark energy.
The mission hopes to test Einstein's theory of general relativity and provide new insights into the fundamental laws of physics.
