If you happen to stroll through Grand Central today or tomorrow, take a look up at the Main Concourse's ceiling—not just because it's a magnificent work of art, but because this week it's getting lit up with the faces of some badass women scientists.

As part of GE's effort to support women in the sciences through their Balance the Equation initiative, the company is sponsoring the aforementioned installation, which kicked off yesterday and runs through tomorrow. Dubbed "Unseen Stars," the show projects the faces of influential female scientists into the Grand Central Terminal's ceiling constellations. Honored women include Millie Dresselhaus, the first woman to win the National Medal of Science in Engineering; Hadiyah-Nicole Green, the first woman to use lasers to kill cancer cells; and Laurie Leshin, who executed space exploration programs at at NASA's Goddard Space Flight Center.

The show runs seven minutes long and repeats on and off until 11:59 p.m. tonight, and from 5:42 a.m. to 11:59 p.m. tomorrow.
