What does the VLT interferometer do?
AWhen they point the VLT telescopes at a star, it dims the star's light, allowing them to see planets that orbit the star.
BIt blocks the harmful ultraviolet light that would otherwise damage the equipment on the telescopes.
CIt uses the light from many stars to make a 3-D map of the Milky Way galaxy.
DIt combines the signals from multiple telescopes to make a much sharper image than a single telescope could.
