New York – Gregory Dobler is an astrophysicist who honed his craft by recording spectral images of quasars and black holes. Now, from a high-rise rooftop in Brooklyn, he is training his lens on the expanding universe of New York City.

Every 10 seconds for two years, Dr. Dobler and his colleagues at New York University’s urban observatory have taken a panorama of Manhattan. Across hundreds of wavelengths of light, they are recording the rhythmic pulse of a living city, just as astronomers capture the activity of a variable star.

“Instead of taking pictures of the sky to see what is going on in the heavens, we are taking pictures of the city from a distance to see if we can figure out how the city is functioning,” says Dr. Dobler, a scientist at NYU’s Center for Urban Science and Progress.
