Fast astronomical photometry of variable stars Super-resolution of astronomical images Artificial intelligence in the analysis of astronomical data The newly discovered Kepler-90i (a sizzling hot, rocky planet that orbits its star once every 14.4 days) was found using machine learning from Google during searching through archived Kepler data - an approach to artificial intelligence in which computers learn to identify planets Data mining in astronomy Cross--identification solves the problem of connecting the source list in observational data to the source list in data archives and catalogs Cross-correlation which makes new discoveries possible based on the analysis of already existing data Nearest- Neighbor Identification which is estimating the photometric redshifts of galaxies or quasars by application of clustering algorithms in a multi-dimensional parameter space Systematic Data Exploration which is the- application of specific queries to a database to make a discovery of new objects or a new class of objects Visualization of astronomical data Data is being collected increasingly often during a single observation, which creates new challenges for data interpretation.
