Hey, baby! (Space/Big Bang Theory).What if you shot a Polaroid of your grandma and the camera spit out her baby picture? Sound impossible? NASA NASA: see National Aeronautics and Space Administration. NASA in full National Aeronautics and Space Administration Independent U.S. astronomers have designed such a gadget--it's a satellite called the Wilkinson Microwave Anisotropy Probe This article or section documents a current spaceflight. Details may change as the mission progresses.  For the radio station, see . (WMAP). And it just snapped a picture of the universe as an infant. The universe began as an unimaginably hot, dense soup of particles and energy. It later expanded and cooled to form stars, galaxies, and planets, according to a scientific theory called the Big Bang. "The Big Bang theory big bang theory n. A cosmological theory holding that the universe originated approximately 20 billion years ago from the violent explosion of a very small agglomeration of matter of extremely high density and temperature. Noun 1. predicted that an afterglow afterglow small amounts of light emitted by a phosphor after the stimulating radiation has ceased. Seen in x-ray intensifying screens and fluoroscopic screens. radiation from the young hot era would still permeate the sky today," explains NASA astronomer Charles Bennett. This afterglow is called cosmic microwave background radiation Noun 1. cosmic microwave background radiation - (cosmology) the cooled remnant of the hot big bang that fills the entire universe and can be observed today with an average temperature of about 2. . WMAP captured the microwaves (high-frequency energy waves) and produced a detailed skymap of the early cosmos. From this and other measurements, scientists determined the universe was born 13.7 billion years ago. How much time is left? Twenty billion years, predict scientists.--KM COSMIC HISTORY An afterglow emerged 380,000 years after the Big Bang. The universe inflated, or expanded, into the galaxies we now see. INFANT UNIVERSE A satellite that sees energy left over from the Big Bang captured the universe at age 380,000. |
