| HIDDEN SUPERNOVA REVEALS DUST-ENSHROUDED "SUPERNOVA FACTORY" | G03-034 | 05/27/03 | 00:02:05 | An exploding star (supernova) veiled by dust in a colliding galaxy is apparently part of a "supernova factory," a region where stars are exploding at a furious rate 200 times greater than in an entire galaxy. The supernova factory is a cosmic version of a "living fossil," providing insight into how stars were born billions of years ago in the early Universe. |

| ITEM (1): A Gigantic Supernova Factory - Using the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope, astronomers discovered the newly-exploded star hidden deep in a dust-enshrouded supernova factory in a galaxy some 140 million light-years from Earth. The dust blocked visible light from the new supernova and others in the factory, preventing astronomers from seeing them with optical telescopes. However, radio emission from the supernovae passed through the dust, granting a glimpse to astronomers using radio telescopes. Courtesy: NASA | ||||
