Microlensing is a form of gravitational lensing, a phenomenon that occurs when one object in space, known as the “lens,” passes in front of a more distant object.

As light from the source travels through the gravitational field of the lens, it becomes warped and magnified by the curvature of spacetime.

Alignments between microlenses and their sources are much more short-lived than larger lenses that endure far beyond human timescales.

Microlensing is now experiencing a step-change in sensitivity that will have major implications for astronomy, cosmology, and the search for extraterrestrial life.

The field is about to be supercharged by the introduction of next-generation approaches and instruments, such as NASA ’s Nancy Grace Roman Space Telescope , due for launch in 2027 .

In 2022 , scientists detected the first isolated black hole using microlensing.

There are an estimated 100 million solo travelers skulking through the Milky Way.

Microlensing continues to shed new light on the nature of dark matter.

We’re now on the cusp of spying an enormous population of celestial bodies.
