Twinkle Twinkle Little Star

Daring the mid-1970's when the Voyager's were launched into space, the media was excited about information the craft would carry of planet Earth and its inhabitants. Should the probe be discovered by another deep-space civilization or land on an inhabited planet, these beings could learn about our solar system and the life it contains. Since that time, radio astronomy and the search for extraterrestrial life became a serious matter for many professional and amateur scientists.

Symposium And Educational Workshop

Radio amateurs have been successfully bouncing VHF, UHF and microwave signals off the surface of the moon, and receiving their echoes, for nearly forty years. EME (Earth-moon-Earth) activities have enhanced the teaching of disciplines as diverse as electronics, astronomy, and physics, with several generations of students having now used measured echoes to determine the distance to, and orbital parameters of, the moon. Penn College students have recently had an opportunity to apply these measurements on a truly grand scale, using EME signals to measure the mass of the Earth. Their results differ from the currently accepted figure by about one percent.

Evaluating Our Result

Any astronomy textbook will reveal multiple measurement errors for each of the intermediate values which we used to estimate the mass of the Earth. For example, the actual period of the lunar orbit is about two percent less than we estimated through our rather crude calendar technique. The lunar radius is in fact nearly four percent greater than we estimated through visual observation and simple trigonometry. And the radius of the moon's orbit turns out to be about a percent and a half less than we calculated from our echo measurements.

Doppler Fun from Austria to Your Hometown

Christian Doppler was born into a family that had built a successful stonemasonry business for 125 years, but his health was always too bad for that arduous occupation. Aftfir studying mathematics and astronomy at two institutes in Vienna, he sought a career as a professor. Despite being quite ambitious and having already published four papers in mathematics, he was turned down for several positions. There was no way to measure tiny shifts in apparent color from stars in those days, so Doppler couldn't directly prove his hypothesis by experiment. Most astronomers pooh-poohed it. Six years later, Doppler set astronomy aside and took on a new scientific interest, studying the Earth's magnetic field as a teacher at the Academy of Mines in Slovakia, His publication topics included changes in Earth's magnetic declination, another subject of interest to hams who are mobile T-hunters.

By James A Hall and Young Dae

INCREASING USE OF THE 2-GHz bands for long-haul communications and for satellite tracking and telemetry, coupled with the growth of navigational systems, radio astronomy and meteorology in the 1 to 2 GHz band, has intensified the need for precision test instrumentation for this range of frequencies. At the same time there is increasing use of phase modulation (< > M) in communications, telemetry, and navigation systems, so phase-modulated signal generators are needed for testing these systems.

The Role of Measurement

The careful astronomical observations of Tycho Brahe and the brilliant analysis of his data by Johannes Kepler illustrate very dramatically the contribution of accurate measurement to scientific progress. Plato, and the Greek philosophers who followed him, believed that the heavenly bodies, being perfect, were composed of the quintessence (literally the fifth essence of matter as distinct from earth, fire, air, and water) and that their motions must be eternal and perfect. Certainly the stars moved in circles, and it was believed that the motions of the planets could be described by an appropriate combination of uniform circular motions. For two thousand years the resolution of planetary motions into circular components was considered the most important problem in astronomy. The heliocentric theory of Aristarchus of Samos (250 B.C.), the geocentric theory of Ptolemy (A.D. 150), and even the heliocentric theory of Copernicus (A.D. 1543), all adhered to the concept of circular motions....

OSCARs in the Classroom

When students at all grade levels arc asked today what pan of the curriculum offered hy schools interests them most, astronomy and space science arc high on their lists. As director of a public school planetarium for the past 20 years, I have seen thousands of students thrill to the sight of the night sky and to the spacecraft, such as Voyager and Viking, that have probed through the blackness of space to the planets of our Solar System, Students often ask me how these spacecraft yet where they are going, and how the information they gather is sent back to waiting scientists on Earth. The also w ant to know how communication satellites work, and how some of those birds can just hant there in the sky.

Such noise is basically due to the statistical unpredictability of energy-level changes within the individual atoms which go to make up the universe, and because of this is always present. In amateur practice, it is generally characterized by its apparent origin. Thus we have, for example, antenna noise which is present with the signal when it arrives from the antenna. This is, in turn, composed of galactic noise which arrives from outer space, atmospheric noise which originates within our own atmosphere and ionosphere, and thermal noise which originates within the conductors of the antenna and feedline (as well as within the components of the amplifier's first rf amplifier stage). Noise of this sort is always proportional to temperature the higher the temperature, the greater the noise voltage. In fact, in radio astronomy noise levels are measured in degrees Kelvin which are a measure of the temperature of the apparent noise source.

Phase Locking Synchronizer for Stabilizing Reflex Klystrons

Klystron Stabilizer

M ICROWAVE signal sources of high frequency-stability and spectral purity are increasingly important to many fit-ids. These include doppler systems, nuclear spectroscopy measurements, spectrum analyzers, as well as telemetry, radio astronomy, and other communications-type work. All of these applications are characterized reduced typically by about 10 times. The synchronized klystron is thus useful as a local oscillator in the most sophisticated receivers such as dop-pler-tracking receivers, telemetry or radio-astronomy receivers, or as a pump in receivers employing masers as low-noise input amplifiers. The arrangement also permits greater latitude in the selection of a klystron, since more emphasis can be placed on achieving other characteristics such as power output, environmental tolerance, tuning characteristics and reliability.

Nomenclature And Letter Symbols

Before developing further the theory of vacuum tubes, a suitable system of notations or letter symbols must be adopted in order to denote easily the many different quantities involved. Although several schemes of notation have been suggested, no one system as yet has come into general use. A satisfactory system of symbols is urgently needed because of the exceptionally large number of different components and aspects of the same quantity necessary to be distinguished in this field. For example, the potential between two points may consist of a steady value on which is superimposed a periodically changing value. We have then to deal with the steady value, average value, peak value, and maximum value of a harmonic component, total instantaneous value, instantaneous value measured from the average value and also from the steady value, etc. The symbols should be such as to suggest, as far as possible, the quantities represented and to burden the memory of the reader as little as possible....

Radio at Green Bank

The active radio observatory at Green Bank, West Virginia, is also a center for preserving some of the major early developments in radio astronomy. Green Bank has become a center for the history of radio astronomy as well as an active radio observatory. A replica of the first antenna that was used to detect radio emissions from space has been constructed near the administr t ion building. The original antenna was built by Karl Jansky, a radio amateur who worked as a scientist at Bell Laboratories in Hoimdel. New Jersey, With his antenna system, Karl Jansk was studying radio noise. The antenna was constructed fora wavelength of 14,6 meters, which is near our 15-meter radio band. He discovered that the strongest noise sources seemed to follow the movement of the sky as the Earth rotated, In 19.10 Karl Jansky determined that the band ol radio noise that he detected seemed to coincide with the Milky Way and that it was strongest near the constellation Sagittarius, the center of the Milky...

Sunspot Cycle

In 1848, a method was introduced for the daily measurement of sunspot numbers. That method, which is still used today, was devised by the Swiss astronomer, Johann Rudolph Wolf. The observer counts the total number of spots visible on the face of the sun and the number of groups into which they are clustered, because neither quantity alone provides a satisfactory measure of sunspot activity. The observer's sunspot number for that day is computed by multiplying the number of groups he sees by ten, and then adding to this value the number of individual spots. As can readily be understood, results from one observer to another can vary greatly. Measurement depends on the capability of the equipment in use, on the stability of the earth's atmosphere at the time of observation, and on the experience of the observer. A number of observatories around the world cooperate in measuring solar activity. A weighted average of the data is used to determine the International Sunspot Number or ISN for...
