Inside the lab: creating artificial stars with lasers

Twinkling stars can make for a magnificent night sky. But to astronomers, this twinkling caused by light traveling through our atmosphere makes it difficult to capture sharp images of space.

To combat this, Dr Martinez Rey uses a powerful laser to make an artificial star appear near the object she is trying to look at with the telescope. She can then remove the negative effect of light captured by the telescope to produce sharper images.
