About Us The Centre for Remote Imaging, Sensing and Processing (CRISP) is a research centre of the National University of Singapore established with funding from the Agency for Science, Technology & Research (A*STAR) of Singapore. CRISP's mission is to develop an advanced capability in remote sensing to meet the scientific, operational and business requirements of Singapore and the region. Our Milestones. CRISP operates a satellite ground station to acquire data from remote sensing satellites, and processes the archived data to standard or value-added products for distribution and research.

The Sloan Digital Sky Survey (SDSS) is one of the most ambitious and influential surveys in the history of astronomy. Over eight years of operations (SDSS-I, 2000-2005; SDSS-II, 2005-2008), it obtained deep, multi-color images covering more than a quarter of the sky and created 3-dimensional maps containing more than 930,000 galaxies and more than 120,000 quasars. SDSS data have been released to the scientific community and the general public in annual increments, with the final public data release from SDSS-II occurring in October 2008.

SIMBAD Astronomical Database SIMBAD Astronomical Database SIMBAD on the Web is the WWW interface to the SIMBAD database. It offers the following functionalities: Query by identifiers and around identifiers Query by coordinates, specifying the radius and the equinox Query by bibcode and partial bibcode Sampling with a set of physical criteria Query by lists of objects, coordinates or bibcodes Display charts for list of objects resulting from coordinates query Moreover, the interface provides links with many other data services : Links to the other CDS services: Tables in VizieR, giving access to the whole catalogued data, links to Aladin images, surveys and observatory logs. Through the coordinates in basic data, you can query around an object, using a provided radius.
The Globe at Night program is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure their night sky brightness and submit their observations to a website from a computer or smart phone. It's easy to get involved - just follow these 5 Simple Steps! Image courtesy Babak A. Tafreshi

Welcome to the Digital Library for Physics and Astronomy The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 10.7 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints.

The units used to describe brightness of astronomical objects. The smaller the numerical value, the brighter the object. The human eye can detect stars to 6th or 7th magnitude on a dark, clear night far from city lights; in suburbs or cities, stars may only be visible to mag 2 or 3 or 4, due to light pollution. The brightest star, Sirius, shines at visual magnitude -1.5. Jupiter can get about as bright as visual magnitude -3 and Venus as bright as -4. The full moon is near magnitude -13, and the sun near mag -26. Glossary of astronomical terms Glossary of astronomical terms

Planet Hunters

Planet Hunters We find new planets by looking at how the brightness of a star changes over time As the planet passes in front of the star we see a dip in the light from it. Depending on how far the planet is from the star, you may see one or many dips in the lightcurve Can you spot the transits?

Few have witnessed what you're about to see Experience a privileged glimpse of the distant universe as observed by the SDSS, the Hubble Space Telescope, and UKIRT Roughly one hundred billion galaxies are scattered throughout our observable Universe, each a glorious system that might contain billions of stars. Many are remarkably beautiful, and the aim of Galaxy Zoo is to study them, assisting astronomers in attempting to understand how the galaxies we see around us formed, and what their stories can tell us about the past, present and future of our Universe as a whole. more The launch of this new version of Galaxy Zoo, the 4th, comes just a few weeks after the site’s 5th birthday. It all started back in July 2007, with a data set made up of a million galaxies imaged by the Sloan Digital Sky Survey, who still provide some of the images in the site today.
