He has encouraged amateur astronomers and advised many U.S. governmental and scientific agencies. CREDIT: ALLAN BURCH A s an Iowa farm boy, I contracted a case of polio and it prevented me from becoming a professional tennis player. When I entered the University of California at Los Angeles, it was still my main ambition to excel at tennis. A mathematics major enabled me to bring home good grades without having to spend much time on studies. But I never made the tennis team. In my junior year, I shifted from mathematics to astronomy because the course Frederick C. Leonard gave had intrigued me, and this determined my career. Subsequently, he obtained a teaching fellowship in astronomy at the University of California at Berkeley for me. After earning my Ph.D., I accepted Harlow Shapley's offer to head Harvard College Observatory's observing program. My interests, besides computing comet orbits and looking for new comets on the photographic platesI found sixincluded galaxies, but the institute's director made it clear by subtle means that this area of research was not for me.

Scholastic Home About Us Site Map Search ... Tools Comets, Quasars, Meteors The following questions were answered by astronomer Dr. Cathy Imhoff of the Space Telescope Science Institute. Where do comets come from? We think that comets are sort of "cosmic leftovers" from the formation of our solar system. There seems to be millions of them far, far out in our solar system, far beyond the orbit of Pluto. They are made up of ice, rock, and dust. They are much smaller than they look. The comet itself may only be a mile across but the tail can be millions of miles long (but it's just thin gas and dust). Why does a comet have a tail behind it? Can meteors hit the earth? You may be surprised that meteors hit the earth all the time! The vast majority are very small and burn up when they hit the earth's atmosphere. A few make it through and hit the ground or fall into the ocean. I have one, about the size of a pebble, in my rock collection. It is very rare for a meteor big enough to do any damage to hit the earth. Have you ever heard of the Meteor Crater in Arizona? I have visited it. It's about a mile across and occurred about 25,000 years ago. Fortunately these days, astronomers are tracking all the larger objects and keeping track of them in orbit. Hopefully if one if them looks like it might hit the earth, we can do something about it. What is the difference between a meteor shower and a meteor storm?

Photo courtesy of NASA Comet Kohoutek Comets Comets are brief visitors from the outer solar system. They change brightness and develop tails as they pass close to the sun. The views of comets in telescopes vary dramatically with each comet.

Comets are insubstantial bodies, loosely knit assemblages of frozen gas and dust that loop around the Sun on highly elongated orbits. They return to the inner Solar System at intervals ranging from a few years to many thousands of years, becoming visible to us on Earth as ghostly, glowing apparitions for a few weeks or months before receding back into obscurity. Our Galaxy has two small companion galaxies called the Magellanic Clouds. To the naked eye they appear like detached portions of the When far from the Sun, a comet shines only by reflecting sunlight. At that stage it is small usually no more than a few kilometres across and faint. Approaching the Sun, the comet warms up, turning its icy surface into gas. Under the influence of the Sun's radiance the gases of the comet begin to fluorescence, in similar fashion to the gas in a neon tube, thereby considerably increasing the comet's brightness. Gas and dust released from the warming comet produce a halo or coma 100,000 km or so in diameter. At the centre of the coma is the nucleus, the only solid part of the comet, consisting of a "dirty snowball" of ice, dust and perhaps some rock. In a large comet the nucleus may be a few tens of kilometres across, but most are only a kilometre or so wide. Well over a thousand million comet nuclei would be needed to equal the mass of the Earth. Not all comets develop tails, but many do. One part of the tail consists of gas blown away from th comet's head by the solar wind of atomic articles streaming from the Sun. The other part of the tail is made up of dust particles liberated from the head by the evaporating gases. Comet tails always point away from the Sun. A comet's tail can extend for 100 million km or so, further than the distance from the Earth to the Sun, as did the gas and dust tails of Comet Hale-Bopp in 1997. Yet, for all its glorious appearance, the tail is less dense than a laboratory vacuum stars shine through it undimmed. The tail of a comet gives it the appearance of speeding across the sky, but actually its movement against the stars is barely noticeable during the course of a night.

Coming Up SA Weather General Forecast Min-Max Forecast Comets and Meteors Comets are "dirty snowballs" from deep space and orbit the sun in areas known as " The Kuiper Belt " and the " Oort Cloud " named after the famous astronomers. Many new objects have, in recent years, been discovered there, some nearly as big as Pluto's moon, Charon. These icy worlds ( - 260 Deg C.) get disturbed and occasionally they fall into the inner solar system, where they become visible due to massive evaporation and ejection of heated gasses and dust, forming the tails of comets. Next year, 2004 August, there should be a bright comet from this area. As they are deep space objects and very faint, you need some good equipment and a dark sky to observe and discover them.

Send it to a friend! Asteroids When someone hears the word asteroid, one of many images may come to mind. Some will think of earthly destruction, others might picture a scene from the movie Star Wars , and yet more will picture the Asteroid Belt. First, there are some facts about asteroids that are commonly mixed up, in an immense, hugely wrong sort of way. For example, in Star Wars , the asteroids are very close to one another. In reality, you'd be lucky to see one in a vast distance. The Asteroid Belt The Asteroid Belt right in between Mars and Jupiter. Lots of asteroids are located there. A common mistake people make is that the Asteroid Belt was a planet that was smashed to big pieces by Jupiter's immense gravity. This is possible, but is not always the theory of choice. The more likely theory is that the asteroids were just leftover stuff that never formed anything really large due to Jupiter's gravity and that there isn't a whole lot of it, compared to the larger planets. Other Locations and Components However, not all asteroids are located in the Asteroid Belt. Some actually orbit the Sun separately and cross the Earth's path often. The chances of actually coming into contact with these large rocky/metallic blobs are slim, but they make for great movies with lots of sickening mushy scenes involving people wishing farewell to each other only coming to find out that the world really isn't going to end. But seriously, they can be a big threat. An asteroid or meteorite was thought to have taken out the dinosaurs, so the threat of them might be cause for some preparations. Maybe we could hide under our desks and chairs with a paper bag over our heads, or maybe we could identify it early enough to blow it up (like in the mushy movies). Anyhow, asteroids are made up of two different materials. Some contain only rock, some contain only iron, and some are a mixture of both. The percentages are as follows:
