When Titanic was released in 1997, part of the media craze surrounding the film was director James Cameron's painstaking work on re-creating the ship, staterooms, and even table linens with historical accuracy. One person not impressed was astrophysicist Neil deGrasse Tyson, who became a vocal critic of Titanic's depiction of that fateful night sky. In meetings with James himself and in public appearances, Neil called out the director for his inaccurate and "lazy" use of a random assortment of stars despite knowing the precise latitude and longitude where the ship sunk, and thus easily capable of re-creating the exact stars Rose would have seen when waiting in the water for rescue.
Finally, with today's Titanic 3D rerelease, scientific accuracy proves victorious as James Cameron admits his perfectionist defeat and changes the stars to reflect what Titanic survivors would've seen at 4:20 a.m. on April 15, 1912. In honor of Neil's constellation concern, download one of these four apps to ensure you always know which stars you're gazing at on a clear night.
