This is an artist impression of exoplanet LTT9779b orbiting its host star. The host star is located on the left as a large white circle with rays coming out of it in orange. The exoplanet is smaller and shown on the right of the image. The side of the exoplanet that is facing its host star is illuminated. The planet is around the size of Neptune and reflects 80% of the light shone on it, making it the largest known “mirror” in the Universe. The background of the image is black and speckled across the image is a starfield, showing innumerable stars of many sizes
