Glowing laser beams cut through the cosmos, pointing to the center of the Milky Way galaxy. (Image credit: A. Berdeu/ESO) Four glowing laser beams blasting through open space converge at the center of our galaxy. But this isn't Star Wars, it's real science. What is it? The European Space Observatory's Very Large Telescope in Chile has four giant Unit Telescopes (UTs), which emitted lasers pointed to the center of the Milky Way galaxy . The UTs create what ESO refers to as "artificial stars" in our atmosphere, about 56 miles (90 kilometers) above Earth's surface. These beams of light allow scientists to see how our planet's ever-changing atmosphere might be distorting incoming light, which is critical for accurately analyzing telescope observations. This information allows the VLT to make real-time changes in response to Earth's atmosphere, making sure that it can see through the cosmos clearly. Why is it incredible?…
