Cosmic ‘web’ seen for first time
The hidden tendrils of dark matter that underlie the visible Universe may have been traced out for the first time.
Cosmology theory predicts that galaxies are embedded in a cosmic web of “stuff”, most of which is dark matter.
Astronomers obtained the first direct images of a part of this network, by exploiting the fact that a luminous object called a quasar can act as a natural “cosmic flashlight”.
