Planetarium Software

A large fraction of astronomy software can be classified as planetarium programs. As the name suggests, they display views of the night sky, which you can alter by changing the time and location. Many programs, though, go far beyond simply displaying images of the sky. They can locate and provide information on thousands or even millions of stars and other objects in the sky, and can simulate views the ordinary observer may never see, such as looking at Earth from space. Some programs provide...

Nebulae

Nebulae were once defined as any cloudlike object visible in the night sky, but as many of those turned out to be galaxies, we now consider nebulae to be clouds of dust and gas. This is still a very open definition there is a wide range of nebulae, from dark, black objects that obscure starlight to those that shine a bright red or blue. Their cloudlike nature also means that nebulae come in almost any imaginable shape. There are different methods of classifying nebulae. One way is by whether...

CCD Cameras

With a computerized telescope and a home PC, you could conceivably run your telescope from the comfort of your own home (a very nice option on cold winter nights ), provided you didn't have to go out and actually look through the telescope. However, thanks to the advent of the CCD camera, you can observe the night sky with your telescope and computer without even going outside CCDs were first developed at Bell Labs in the late 1960s as memory storage devices. However, researchers found that...

Stellar Basics

The stars we see in the night sky are suns like our own in the sense that they are giant balls of hydrogen and helium that create their energy through nuclear fusion. However, there's a wide range of stars that can vary greatly from our own run-of-the-mill Sun. Some are giant red or blue stars, many times larger and brighter than the Sun, while others are much smaller and much dimmer red and white dwarfs. Our Sun lies in the middle, one of many average stars. Viewers can easily see part of this...

Learning about the Moon

It should be no surprise that the Moon is the most-studied body in the night sky. It has been the subject of naked-eye observations since antiquity and was one of the first objects Galileo studied with his telescope. More recently, it has been the target of a fleet of spacecraft from the United States and the former Soviet Union, and it is the only world other than Earth where humans have set foot. This intense analysis means we have learned a lot about our neighboring world, although many...

Halley Hyakutake and Hale Bopp

The most famous known comet is certainly Halley's comet. Its appearances every 74 to 76 years have been traced back in the historical record to at least 240 B.C.E. This large comet usually makes a bright appearance in the night sky when it passes though the inner Solar System, with the notable exception of its last passage in 1985 86. There are general and scientific resources about the comet at halley.html and While the last passage of Halley's comet through the inner Solar System was not a...

Astronomical Image Processing Software

Picture might be worth a thousand words, but if it is impossi- ble to clearly see what is trying to be communicated, then the vocabulary might be insufficient. While astronomical image processing software might seem to be strictly in the domain of those fortunate enough to have a CCD camera, in fact there are many uses for such software. For example, a broad selection of CD-ROMs containing raw image data from the Voyager flights through the outer Solar System are available, and image processing...

Satellite Tracking Software

For many, the fascination with the night sky has to do not only with the relatively static stars and planets that appear to the naked eye, but with the moving points of light that are the artificial Earth satellites launched by man, ranging from the Space Shuttle and Mir space station to small, relatively unknown satellites. Such Earth satellite tracking software is dependent upon regularly updated positional data that is used to locate and track these artificial moons. Fortunately, there are...

Other Galaxies

As astronomers studied the sky with more powerful telescopes, new objects came into view. These objects did not have the pinpoint sharpness of stars, but rather were dim and fuzzy. They were dubbed nebulae from the Latin word for clouds. Some of these nebulae had distinctive shapes, including spirals and ellipses. A debate ranged in the astronomical community for decades over what they were. Some argued that they were just clouds of gas and dust, with perhaps small clusters of stars, within our...

Black Holes

Neutron stars are supported from further collapse by the pressure neutrons exert on each other in the densely packed interior. This works for stars of masses up to about three times the Sun's. However, for even more massive stellar remnants left behind by supernova explosions, the force of gravity becomes so strong that not even the neutrons can resist it. What keeps the star from collapsing further Nothing. No known force in the universe can keep the star from collapsing into an infinitely...

Other Suns Other Planets

We have long since recognized that the stars we see in the night sky are suns like our own Sun, and many astronomers have thought that at least some of them may have planets.

However, thanks to new observing techniques and better, more powerful...

Radio astronomy played a role in the discovery of active galaxies, and it has also helped uncover something even more unusual. The first surveys of the sky at radio wavelengths started in the mid-1950s by astronomer Grote Reber, who used a homemade telescope in his Illinois backyard. Early surveys found a number of strong radio sources some of which were traced to supernovae, others to the nucleus of our galaxy, but one dubbed Cygnus A, as it was the first radio source discovered in the...

Colliding Galaxies

Space is incredibly vast, and although galaxies are large and numerous, most of the universe is still empty space. It thus seems unlikely that two galaxies would come close to one another, let alone come into contact. Yet we have seen several cases where galaxies are in the slow process of crossing each other's paths, with varying consequences. What happens when a pair of galaxies come into contact depends largely on their sizes. If one galaxy is much more massive, the tidal forces it exerts on...

Computer Controlled Telescopes

Moving a telescope to observe a particular object can often be a frustrating, tedious experience, particularly for beginners. Centering a telescope on a particular star or object can take some time. Finding a dim object may require star-hopping moving from one (brighter) star to another to get to the location of the dim object.
