Astronomers Release Enormous Database of Variable-Luminosity Celestial Objects 54

wisebabo writes "According to a Caltech news release, 'Astronomers from the California Institute of Technology and the University of Arizona have released the largest data set ever collected that documents the brightening and dimming of stars and other celestial objects—two hundred million in total. The night sky is filled with objects like asteroids that dash across the sky and others—like exploding stars and variable stars-that flash, dim, and brighten. ... Using the Catalina Real-Time Transient Survey, a project led by Caltech, the astronomers systematically scanned the heavens for these dynamic objects, producing an unprecedented data set that will allow scientists worldwide to pursue new research.' So, anybody going to write a program looking for artificial sequences? (primes, Fibonacci, integers.) Wouldn't a good way to attract interstellar attention 'cheaply' would be to put up some (very) big solar sails in orbit around a star to modulate (and maybe collect!) its output? With 'micro-transits' being a preferred way to find exoplanets, somebody looking could stumble across this."
