Astronomers have long believed that pulsars are produced by stellar explosions. Until now, though, no pulsar had been observed so soon after its birth. The first pulsar was discovered in 1967, its radio signals so regular that they were suspected of coming from an alien civilization. Several hundred pulsars have since been found...

Junior sprinter Meredith Rainey had a stellar performance running the first leg of the victorious 4-by-220 yard relay, placing second in the 200-meter dash in 25.05 and qualifying for nationals in the 400-meter dash with a time of 54.2 seconds...
Evidence leading to the hypothesis of a double supernova, however, was collected by Kirshner and his co-workers while examining the remnant of an ancient explosion, which took place more than 4000 years ago. Astronomical observers uncover about 20 of such stellar fossils, which are less useful than phenomena occuring more recently and closer to the Earth...
Kirshner says one important reason to analyze these phenomena is because they are theorized to be the source of all heavy elements in the universe. When the stellar explosion takes place, it fuses all of the star's abudant light elements, like hydrogen and helium, into heavy elements, like iron. "There is a real sense that supernova elements are actually the physical origin of [the heavy] chemicals in our body," Kirshner says. The elements these supernovae create are in everything, he says, including "life, earth, iron and gold...
