Newfound Planet Orbits Backward Planets orbit stars in the same direction that the stars rotate. They all do. Except one. A newfound planet orbits the wrong way, backward compared to the rotation of its host star. Its discoverers think a near-collision may have created the retrograde orbit, as it i...

Title: PynPoint: An Image Processing Package for Finding Exoplanets Authors: Adam Amara, Sascha Quanz We present the scientific performance results of PynPoint, our Python-based software package that uses principle component analysis to detect and estimate the flux of exoplanets in two dime...
John Canton FRS (31 July 1718 - 22 March 1772) was an English physicist. In 1750 he read a paper before the Royal Society on a method of making artificial magnets, which procured him election as a fellow of the society and the award of the Copley Medal. He was the first in England to verify Benjamin Frankl...
