Mirabel and Luis Rodriguez of the Center d'Etudes de Saclay in France. They observed radio emission from jets and determined that the jets were traveling faster than 90 percent of the speed of light, or roughly 600 million miles per hour. The half-hour spacing between the ejections may be telling us that what we had thought were smooth, continuous outflows may in fact be intermittent explosions.
