- The Planck mission, launched on May 14, 2009, is measuring the Cosmic Microwave Background (CMB) over a broad range of far-infrared wavelengths, and to an unprecedented accuracy. The measurements will enable the extraction of essentially all of the information that can be obtained from CMB temperature anisotropies. Planck is expected to provide answers to many fundamental questions about the early history and evolution of our universe. Specifically, it is giving scientists the data needed to: set tight constraints on cosmological parameters

Timeline of United States discoveries Comet Hale–Bopp (formally designated C/1995 O1) was perhaps the most widely observed comet of the 20th century and one of the brightest seen for many decades.It was visible to the naked eye for a record 18 months, twice as long as the previous record holder, the Great Comet of 1811.Hale–Bopp was discovered on July 23, 1995, at a great distance from the Sun, raising expectations that the comet would brighten considerably by the time it passed close to Earth.t was visible to the naked eye for a record 18 months, twice as long as the previous record holder, the Great Comet of 1811.

The Orbital Period of Hale-Bopp Around the Sun Discovered by Alan Hale and Thomas Bopp in 1995, the Hale-Bopp comet came within 1.315 AU of Earth in 1997. One AU is 150 million kilometers (93 million miles). Scientists have computed its orbital period so you can find out when Hale-Bopp will return.

- Numerically, the measure is close to the known size of atoms. This encouraged Bohr to use Planck's constant in searching for a theory of the atom. Planck had introduced his constant in 1900 in a formula explaining the light radiation emitted from heated bodies.

- The Heinrich-Hertz-School The physicist Heinrich Hertz, born in Hamburg (1857 - 1894), discovered electromagnetic waves. His scientific works formed the basis for radio and television technology. The Heinrich-Hertz-School is the only kooperative Gesamtschule in Hamburg. The school was founded in the year 1968. (URL: www.hh.schule.de/hhs/english/school.htm)

- On October 1, 1957, 3 days before the launch of their first sputnik, the Russians released the frequencies to be used for their space probes. Western experts were surprised to notice that these frequencies, at 20 and 40 megahertz, were right in the middle of amateur radio bands.

Planck constant The Planck constant is named after Max Planck, the instigator of quantum theory, who discovered it in 1900. Classical statistical mechanics requires the existence of h (but does not define its value). Planck discovered that physical action could not take on an arbitrary value.n principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century.

Voyager 1 About Voyager 1. Voyager 1 is a space probe launched by NASA on September 5, 1977. Part of the Voyager program to study the outer Solar System, Voyager 1 launched 16 days after its twin, Voyager 2. Having operated for 38 years and 13 days, the spacecraft still communicates with the Deep Space Network to receive routine commands and return data.

The Hubble space telescope: 'It's a terrific comeback story' Nasa hoped to launch Hubble in 1983, but the schedule slipped. The team was about ready in 1986 when Nasa suffered one of the greatest blows in its history. On 28 January that year, the space shuttle Challenger disintegrated over the Atlantic Ocean, killing its crew of seven.

- On October 8, 1945 Raytheon filed a U.S. patent for Spencer’s microwave cooking process, and a prototype was developed for testing. It was almost six feet tall, weighed 670 pounds, and sold for the equivalent of $20,000 in today’s dollars.

Planckâs theory and thermodynamics Planck’s theory and thermodynamics Max Planck described the methods he used to develop his famous blackbody radiation equation in a series of lectures at Columbia University in 1915. These lectures were recorded , and the published document is the information source for these articles.

Laser tag In 1986, the first Photon toys hit the market, nearly simultaneously with the Lazer Tag toys from Worlds of Wonder and several other similar infrared and visible light-based toys. Worlds of Wonder went out of business around 1988, and Photon soon followed in 1989, as the fad of the games wore off.

Chandra X-ray Observatory The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a space observatory launched on STS-93 by NASA on July 23, 1999. Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors.istory [edit]. In 1976 the Chandra X-ray Observatory (called AXAF at the time) was proposed to NASA by Riccardo Giacconi and Harvey Tananbaum. Preliminary work began the following year at Marshall Space Flight Center (MSFC) and the Smithsonian Astrophysical Observatory (SAO).

Planck's law Planck radiation has a maximum intensity at a specific wavelength that depends on the temperature. For example, at room temperature (~ 7002300000000000000♠300 K), a body emits thermal radiation that is mostly infrared and invisible.

History of quantum mechanics The phrase quantum physics was first used in Johnston's Planck's Universe in Light of Modern Physics (1931). With decreasing temperature, the peak of the blackbody radiation curve shifts to longer wavelengths and also has lower intensities.
