On Monday, Grand Central Terminal unveiled their new LED-lighted Grand Concourse ceiling, which will not only return the constellations to their previous glory, but reduce energy costs for the MTA. Steve Stroh of Metro-North said the new lights will last "twice as long as the old system," and that it uses "about 60% less electricity than the original lights." The lights will be on from 5 a.m. to 2 a.m. every day, and each one will mimic the intensity of its star as seen from earth. “When gazing up, 125 feet above the Tennessee pink marble floor, one cannot see all the lighted stars at once,” says the MTA. "As people walk across the Concourse floor and their vantage point changes, different stars appear, giving a twinkling impression."
