"Astronomers are living in a golden age of bigger and better telescopes. But
even our most advanced technology pales in comparison to the power of nature’s
own “cosmic magnifying glasses” – strong gravitational lenses.
In less than 50 years we have gone from the first-ever discovery of a strong
gravitational lens to now finding thousands. As new telescopes come online,
we’re expecting to discover thousands more.
With these lenses, we can look deep into the universe, and catch glimpses into
the most puzzling of contemporary cosmic mysteries: dark matter and dark
energy.
So, what are gravitational lenses and how do they work?"
