Forecasting a Supernova Explosion
February 6, 2013
Type II supernovae are formed when massive stars collapse, initiating giant explosions. It is thought that stars emit a burst of mass as a precursor to the supernova explosion. If this process were better understood, it could be used to predict and study supernova events in their earliest stages. New observations from a team of astronomers including Carnegie Institution's Mansi Kasliwal show a remarkable mass-loss event about a month before the explosion of a Type IIn supernova.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
