Astronomers analyzed the gravitationally lensed image of a distant galaxy to test the nature of dark matter.
Astronomers use cosmic magnifying lenses to peer into the universe's distant past.
The latest data release from a survey of 31 million galaxies reveals that our universe is even smoother than we thought it was.
Thanks to the effects of gravitational lensing, a team of astronomers was able to reconstruct a distant galaxy and study its unexpectedly clumpy star forming regions.
Astronomers analyzing a new sky survey have found that the distribution of dark matter in the modern universe is smoother than predicted from observations of a far younger universe.
