Running Scientific Applications on Academic Clouds

Commercial clouds can prove expensive, especially for long term use of for massive data storage. This week I report on some experiments on processing Kepler data sets on academic clouds. We are trying to see whether these experimental clouds offer … Continue reading

The Kepler Mission: A Gold Mine of Variable Stars

The Kepler Mission was designed to find transiting, Earth-like exoplanets, by continuously observing over 100,000 stars in a field centered in the constellation of Cygnus. Two years into the mission, it is also providing an extraordinarily rich collection of time-series … Continue reading

Finding New Planets With Cloud Computing?

Surveys for Transiting Planets Planet finding is a heavy industry these days. The Kepler satellite (http://kepler.nasa.gov/), launched on 06 March 2009, is a NASA mission that uses high-precision photometry to search for transiting exoplanets around main sequence stars. The French … Continue reading
