Astronomer uses Kepler telescope’s data in hunt for spacecraft from other worlds by Peter Brannen.
From the post:
In the field of planet hunting, Geoff Marcy is a star. After all, the astronomer at the University of California at Berkeley found nearly three-quarters of the first 100 planets discovered outside our solar system. But with the hobbled planet-hunting Kepler telescope having just about reached the end of its useful life and reams of data from the mission still left uninvestigated, Marcy began looking in June for more than just new planets. He’s sifting through the data to find alien spacecraft passing in front of distant stars.
He’s not kidding — and now he has the funding to do it.
Great read!
BTW, if you want to search older data (older than Kepler) for alien spacecraft, consider the digitized Harvard College Observatory Astronomical Plate Stacks. The collection runs from 1885-1993. Less than ten (10%) of it has been digitized and released.
