...first bright supernova since Harvard was founded," said Professor Of Astronomy Robert P. Kirshner '70, who studying ultraviolet (UV) light emitted form the bright supernova. The most recent supernova observable from Earth with the naked...
...jumped from near invisibility to respectable brightness literally overnight, and while its wave-front speed was high, its spectrum revealed the unmistakable hydrogen-bearing signature of a Type II. But when the International Ultraviolet Explorer satellite reported a rapid drop in ultraviolet light, scientists began to wonder. Says Robert Kirshner, of the Harvard-Smithsonian Center for Astrophysics: "The spectrum we're seeing in the ultraviolet resembles the spectrum of a Type I. That's a puzzle." Admits Texas' Wheeler: "There are some funny features in this supernova...
Within a couple of weeks, says Harvard's Robert Kirshner, the temperature of 1987A's expanding shell should drop from its current 10,000 degrees C to roughly 6,000 degrees C, about the same temperature as our sun's surface. During the explosion, though, internal temperatures climbed to billions of degrees, and elements like silicon, sulfur and platinum, synthesized by the star, began spewing out over a vast region of space, where they will form clouds of gas and dust that can coalesce into new stars and planets. Indeed, most of the elements abundant on earth today, except hydrogen...
...chance that they might finally be able to pinpoint a specific progenitor star, which could finally confirm or recast their theories about how supernovas explode, has astronomers beside themselves with excitement. "It's like Christmas," says Woosley. "We've been waiting for this for 383 years." Agrees Kirshner: "Everyone in the field has been calling each other up, partly for scientific reasons and partly for sheer pleasure. It's like when someone has a baby -- it's a great event, and you just want to talk...
...know, the universe can expand forever and Harvard can have a 350 billionth birthday," Kirshner said...
