Moon crater classification
Moon Mappers' objective is to provide a large, scientifically robust and geographically broad catalog of lunar craters and other features. Specifically, the identification, cataloging, classification, and analysis of small impact craters (10-1000 m in size), atypical impact formations (e.g., elliptical, exogenic dark-haloed, and concentric craters; bright rays; ejecta exclusion zones), volcanic structures (e.g., vents, endogenic dark-haloed craters, domes, rilles), and other unusual/interesting geologic features that can be used to help answer several fundamental questions in lunar science.
The Galaxy And Mass Assembly (GAMA) Survey is an international project to exploit the latest generation of ground and space-based survey facilities. Its aim is to study cosmology and galaxy formation and evolution from scales of thousands up to millions of light years across. The science goals include furthering our understanding of how the mass of stars within galaxies builds up over time, how and when do galaxies form their stars, how are those previous questions related to a galaxy’s environment, and at what epoch did star-formation and mass-build-up dominate? Visual morphologies from Galaxy Zoo will allow us to explore if, how, when, and where galaxies transition from one type into another, what impact this has on the formation of stars, and to look for new types of unique and interesting galaxies.
The AAVSO Solar Section is an international group of observers dedicated to observing the closest variable star in the sky - our Sun. The AAVSO Solar Section monitors and records sunspots from which the American Relative Sunspot Numbers (RA) are computed.
