The systematic error, first detected by COBE in the dipole evaluation of the "CMB" temperature [11], may be, in actuality, the critical proof. As a result, it appears that the COBE satellite provides the first evidence that the "CMB" monopole does indeed arise from the Earth. A radio telescope is used to detect, collect, and analyze electromagnetic radiation that originates in astronomical objects or the space between them, and has wavelengths between 0.001 and 1 meter. At that time, the CMBR had been observed only in a fairly narrow part of its spectrum, because most of that spectrum was blocked by … CoBE (Cosmic Background Explorer) was the brainchild of a young graduate student in the 1970's, John Mather. By studying these fluctuations, cosmologists can learn about the origin of galaxies and large scale structures of galaxies and they can measure the basic parameters of the Big Bang theory . Learn vocabulary, terms, and more with flashcards, games, and other study tools. Only with very sensitive instruments, such as COBE and WMAP, can cosmologists detect fluctuations in the cosmic microwave background temperature. Operating 900 kilometers above the Earth, COBE is high enough that the residual effects of the Earth's atmosphere do not affect its instruments, yet low enough to minimize interference by the charged particles in the Earth's radiation belts. The atmosphere does such a good job that telescopes designed to detect these portions of the electromagnetic spectrum have to be positioned outside the atmosphere. Start studying Astronomy Dates & Big Bang Webquest. The regions of lower-than-average temperature come in a variety of sizes, but even the smallest of the colder areas detected by COBE is far too large to be the precursor of an individual galaxy, or even a supercluster of galaxies. The light from the Big Bang, which happened almost 14 billion years ago, has been travelling through the universe ever since, allowing us to detect this “afterglow” on Earth. Studies of astronomical objects in high energy X-rays and gamma rays began in the early 1960s. One of three instrument packages aboard COBE, the satellite was placed into a near-polar orbit. ... what does the COBE satellite detect. Scientists working with the data from the COBE satellite did indeed detect very subtle temperature differences—about 1 part in 100,000—in the CMB. ... what does the WMAP satellite measure.
