Did you know the pioneer of modern astronomy, Henrietta Swan Leavitt, was from Freedom’s Way NHA
Henrietta Swan Leavitt was a Harvard “computer,” or, a human calculator, in the 1900s. Though this profession was looked down on by male scientists, it was through her work that Leavitt discovered the relationship between the cycle and the level of brightness of Cepheid stars. Cepheid stars are a kind of variable star, with light that sums and brightens regularly. What Leavitt found about the connection between timing and brightness in these stars allowed her to calculate the distance to the star.
This discovery, “Leavitt’s Law,” went unrecognized until after her death at 53. Then, her findings paved the way for other astronomers to calculate the distance between stars everywhere, and to the discovery that the universe is always expanding.

Star trail from Ghatkopar has always been impossible due to pollution! All thanks to lockdown and 9 pm lights off task. Got just 10 mins to shoot though, but it was worth it. Hope things quickly get back to normal and we start respecting nature 🙏
