INSTRUCTIONS FOR USING THE ASTROGATOR’S HANDBOOK, DELUXE EDITION

Introduction

If you go to any library in the world and check out a book on astronomy, you will find it filled with beautiful star maps that plot the angular positions of the stars in Earth’s sky to within a few tenths of a degree. These maps will have the lines of celestial latitude and longitude plotted on them, and will have the outlines of the constellations superimposed for easy recognition of the patterns of light we see in the night sky.

Unfortunately, these star maps are of only limited use to a science fiction writer. Interstellar space is the natural habitat for the science fiction writer, and we care little about where the stars appear in the night sky of Earth. What we really want to know is where the stars are located with respect to one another. After all, when plotting an interstellar adventure, we may wish to send our hero’s ship from Procyon to Aldebaran. Knowing where those two particular points are in the night sky of Earth is much less useful to us than knowing where they are relative to one another in three- dimensional space! The motto of the science fiction writer is, “Never mind telling me about the mythical beasts in the sky. Tell me how to get there!”

The Sci Fi - Arizona Astrogator’s Handbook, DELUXE Edition was designed to plug this obvious hole in humanity’s knowledge of the stars. Rather than showing you maps of the stars as they appear to us here on Earth, we have taken an external view of local space. We have plotted the positions of the nearest 3500 stars surrounding the sun (Sol) as they would appear to an observer in the vicinity of Polaris, the North Star, looking down on our local space from above.

One of the problems with displaying the absolute positions of stars in three-dimensional space is that current technology requires us to draw star maps using two-dimensional methods. Over the years, various approaches to this problem have been attempted with limited success. Most mapping procedures rely on isometric projection. That is, they display the stars as they would appear to an observer viewing them obliquely from outside local space, much as we can simulate the three-dimensional nature of a house by drawing an isometric view of it on a sheet of paper. Unfortunately, most of us are not good at looking at an isometric projection of a complex three- dimensional object and visualizing that object in our heads. This is especially true if the view contains numerous separate object. It takes only a few dozen stars plotted on an isometric star map to make the pattern too complex for the average person to visualize.

Another approach to star mapping is to plot red-and-green dots on a piece of paper and then use the old 3-D movie glasses to provide the illusion of three dimensions. Here, too, most people have difficulty seeing the true positions of the stars in space, as the dots tend to fade in and out of focus. The method has the further problem of giving many people headaches if they wear the red-and- green filter glasses for too long. The Sci Fi - Arizona Astrogator’s Handbook, DELUXE Edition solves these problems by using a layered 3-D mapping approach that is analogous to the two-dimensional maps that we are all familiar with. The layered 3-D map is constructed by taking the 150 light-year cube of space that surrounds or star, Sol, and cutting it into seven distinct layers that are 20 to 25 light-years thick.

All of the stars in each layer are then displayed in a standard map format, with the X- and Y- coordinates displayed by the position of the star on the map’s two-dimensional grid. The Z- coordinate is displayed as a positive or negative number denoting the star’s distance above (or below) the position of Sol. In this way, the user is able to visualize the relative positions in 3-D space by noting where a particular star lies on a horizontal plane parallel to the plane of the Earth’s equator, and then using the Z-coordinate to visualize the relative position along a vertical axis aligned with the Earth’s axis of rotation. If this seems complicated, check out the star maps. It is much easier to do than it is to describe.

Overall, the maps encompass 3500 stars that occupy a cube that reaches out 75 light-years in all directions from Sol, and covers a region of space encompassing 3,375,000 cubic light-years in volume. The plotted stars are virtually all of the stars for which we currently have precise position data.

The purpose of this manual is to aid science fiction writers in the plotting of their stories, to allow students and educators to gain a true understanding of the structure of local space, and for the use of anyone who just wants to know where any particular star is really located in the sky. To aid in this quest, The Astrogator’s Handbook, DELUXE Edition is divided into five sections:

Reading Layered 3-D Star Maps

Appendix 1 contains 7 overview star maps and 63 detailed quadrant star maps of the region of space surrounding Sol and Earth. Space is broken up into seven layers, and each layer is subdivided into 9 quadrant maps. Each quadrant map represents a volume of space that is 50 light- years square and 20 light-years deep (25 light-years deep for the northernmost and southernmost layers. See Figure 1: Quadrant Maps 50 50 50

Figure 1: 3-D Layered Star Map Arrangement

The levels are:

• Far North Stars — Level N3 shows the stars that are 50 to 75 light-years to the north of Sol, in the direction of the North Star, Polaris. Polaris itself is not shown since, at 680 light-years distance, it is far outside the boundaries of the map. The northern stars are visible in the northern hemisphere.

• Middle North Stars — Level N2 shows the stars that are 30 to 50 light-years to the north of Sol.

• Near North Stars — Level N1 shows the stars that are 10 to 30 light-years to the north of Sol.

• Home Stars — Level 0 shows the stars that are 10 light-years north of Sol to 10 light-years south of Sol. Obviously, this includes our own sun, which has a coordinate among the Home Stars of 0,0,0.

• Near South Stars — Level S1 shows the stars that are 10 to 30 light-years to the south of Sol.

• Middle South Stars — Level S2 shows the stars that are 30 to 50 light-years to the south of Sol.

• Far South Stars — Level S3 shows the stars that are 50 to 75 light-years to the south of Sol, directly opposite the direction of the North Star, Polaris. The southern stars are visible in the southern hemisphere.

Because the scale of the stars would be too small if we attempted to plot each level on a single map (150 light-year square), each level has been divided up into a 3 X 3 grid, for a total of 9 quadrant maps per level. Figure 2 shows the arrangement of the quadrant maps.

Reading Star Maps in Appendix 1

There are 70 star maps in Appendix 1, including 7 overview maps showing all of the stars in each level and 63 detail maps that show the stars in much more detail. Each map shows the position of the star, along with a numerical label that includes 1) the number of the star on that map, 2) the spectral type, 3) the Z-coordinate above or below Sol, and 4) the common name for the star (if available). Because the layered 3-D star map is presented in a familiar mapping format, it is relatively easy to visualize the positions of the stars in three-dimensional space by observing their positions on the map and then visualizing the relative north-south positions from the Z-coordinate.

Figure 3 shows a typical overview star map, with the individual quadrant maps noted. Dimensions are in light-years.

Figure 3: The Home Stars

While the overview map gives a good overall picture of the arrangement of stars in the seven layers that make up the 150 light-year cube centered on Sol, the scale is too large to be able to provide meaningful information about each star. The quadrant maps are used to provide detailed information about stars. Figure 4 is a typical quadrant star map. Dimensions are in light-years.

Figure 4: Quadrant Star Map, Home Stars, Center Quadrant

Beside each star are one or two text labels. These provide information about the star. For example, take the star that is at the bottom-left corner of the map. Its two labels are:

CE Boo 136, M0, 10

CE Boo is an abbreviation of the star’s popular name, CE Bootes.

136 is the star number on the map. Specifically, CE Bootes is the 136th star on this particular map. To find additional information on the star, turn to the Star Tables in Appendix 2, find the corresponding table to the star map on which the star appears, and then look for Star No. 136. The table will give the star’s position in Right Ascension and Declination, as well as in X, Y, and Z coordinates. It will provide the star’s full spectral type, indicating its color and size, as well as its absolute magnitude, which is an indication of its physical size. The table also includes remarks, such as the separation between binary stars and other information of use to astronomers and science fiction writers.

MO is the star’s spectral class, which denotes that CE Bootes is a red star. If the spectral class of CE Bootes were unknown, then the label would read 136,,10.

10 is the Z-axis coordinate for CE Bootes. It indicates that the star lies 10 light-years to the north of Sol. The star directly to the right of CE Bootes has a label of 131, M3.5,-10, indicating that it is another M-class red star and that it is located 10 light-years south of Sol. Thus, although CE Bootes and this M3.5-class star appear to be close to one another, they are actually separated by 20 light-years in elevation. You can think of CE Bootes as hovering above the plane of the map while the M3.5 star hovers an equal distance below the plane of the map.

Navigating Between Star Maps in Appendix 1

The star maps in Appendix 1 have been arranged to allow the reader to quickly navigate between maps. In addition to star data, the maps include navigation markers that make it easy to determine the map’s position in the 63-map array that makes up the surrounding 3500 stars. See Figure 5

Reading Star Tables in Appendix 2

Although the quadrant star maps contain considerable data with regard to the 3500 stars that are closest to Sol, they do not include all of the data for each star. However, if you desire to know more about a star, then that data is available in the star tables of Appendix 2.

The first number in the numeric label next to each star is the table identity number (Table No.). By knowing the table number, it is possible to look up the details of that particular star by turning to the Star Tables in Appendix 2. The table numbers begin at 1 on each quadrant map and are assigned sequentially in order of increasing distance from Sol. To find the detail information on each star, merely note the Table No., and the Level and Quadrant Index number at the edge of each map.

After turning to Appendix 2, match up the Level/Quadrant Index Number for the map with that of one of the star tables, and then look up the star with the same Table No. See Figure 6.

Using the Star Tables and Maps in Science Fiction Writing

Appendix 2 provides detailed data on the 3500 stars closest to Sol in 120 pages of star tables. Typically, a science fiction writer will be interested in stars around which he or she can place habitable worlds for the purpose of writing a story. An example of how the star tables and maps may be used to plot a piece of fiction follows:

If the writer is interested in finding a star around which there may be Earth-like planets, he or she begins by looking at the column labeled “Spectral Type” in the Star Tables, or else looking at the middle identifier on the Star Tables. The sun is a G2V spectral class star. This means that it is a yellow-white (G) spectral type star that is classed as a dwarf (V). The 2 signifies that the sun’s temperature places it in the upper end of the G-spectral class, which extends from G0 (6000C) to G9 (5000C). Habitable worlds are most likely found around stars that are of similar spectral classifications (F, G, or K). The brightest stars (O, B, and A) are too hot for life as we know it (due to their ultraviolet output) and too short lived for evolution to have had a chance to work on any planets that orbit them. The coolest stars (M, R, N, S) are mostly red giants and probably destroyed any planets they might have had when the entered their current phase of stellar evolution.

After selecting a suitable spectral type, determine if the star is part of a multiple star system. Whether life will develop in a multiple star system is questionable. Multiple star systems are noted by having the same numerical Gliese IDs, with A, B, or C noted in the Components column. Two stars with the same coordinates are part of a multiple star system. Having two large stars in the sky will probably make conditions on planets too variable. However, if one star is large and the other small, then the system conditions may not be dramatically different than here in the Solar system. Procyon is an example of a potentially habitable multiple star system.

When you have chosen a suitable star, note the star map on which it is located and its X, Y, Z coordinates. Use the X and Y coordinates to locate the star on the map and the Z coordinate to visualize its position in 3-D space. If you have trouble visualizing, use a straw or other aid to locating the point in space that represents the star’s position. Note: The Z-axis has the same units as the X and Y axes, causing the seven star maps to form a perfect cube (like a 3-D chess board).

A listing of the codes used in the star tables, along with a list of the constellations, can be found in the next sections.

NOVELS

1. Life Probe - US$7.50

The Makers searched for the secret to faster-than-light travel for 100,000 years. Their chosen instruments were the Life Probes, which they launched in every direction to seek out advanced civilizations among the stars. One such machine searching for intelligent life encounters 21st century Earth. It isn’t sure that it has found any...

2. Procyon’s Promise - US$7.50

Three hundred years after humanity made its deal with the Life Probe to search out the secret of faster-than-light travel, the descendants of the original expedition return to Earth in a starship. They find a world that has forgotten the ancient contract. No matter. The colonists have overcome far greater obstacles in their single-minded drive to redeem a promise made before any of them were born...

Appendix A

3. Antares Dawn - US$6.00

When the super giant star Antares exploded in 2512, the human colony on Alta found their pathway to the stars gone, isolating them from the rest of human space for more than a century. Then one day, a powerful warship materialized in the system without warning. Alarmed by the sudden appearance of such a behemoth, the commanders of the Altan Space Navy dispatched one of their most powerful ships to investigate. What ASNS Discovery finds when they finally catch the intruder is a battered hulk manned by a dead crew. That is disturbing news for the Altans. For the dead battleship could easily have defeated the whole of the Altan navy. If it could find Alta, then so could whomever it was that beat it. Something must be done…

4. Antares Passage - US$7.50

After more than a century of isolation, the paths between stars are again open and the people of Alta in contact with their sister colony on Sandar. The opening of the foldlines has not been the unmixed blessing the Altans had supposed, however.

For the reestablishment of interstellar travel has brought with it news of the Ryall, an alien race whose goal is the extermination of humanity. If they are to avoid defeat at the hands of the aliens, Alta must seek out the military might of Earth. However, to reach Earth requires them to dive into the heart of a supernova.

5. Antares Victory – First Time in Print – US$7.50

After a century of warfare, humanity finally discovered the Achilles heel of the Ryall, their xenophobic reptilian foe. Spica – Alpha Virginis – is the key star system in enemy space. It is the hub through which all Ryall starships must pass, and if humanity can only capture and hold it, they will strangle the Ryall war machine and end their threat to humankind forever. It all seemed so simple in the computer simulations: Advance by stealth, attack without warning, strike swiftly with overwhelming power. Unfortunately, conquering the Ryall proves the easy part. With the key to victory in hand, Richard and Bethany Drake discover that they must also conquer human nature if they are to bring down the alien foe …

6. Thunderstrike! - US$7.50

The new comet found near Jupiter was an incredible treasure trove of water ice and rock. Immediately, the water-starved Luna Republic and the Sierra Corporation, a leader in asteroid mining, were squabbling over rights to the new resource. However, all thoughts of profit and fame were abandoned when a scientific expedition discovered that the comet’s trajectory placed it on a collision course with Earth!

As scientists struggled to find a way to alter the comet’s course, world leaders tried desperately to restrain mass panic, and two lovers quarreled over the direction the comet was to take, all Earth waited to see if humanity had any future at all…

7. The Clouds of Saturn - US$7.50

When the sun flared out of control and boiled Earth’s oceans, humanity took refuge in a place that few would have predicted. In the greatest migration in history, the entire human race took up residence among the towering clouds and deep clear-air canyons of Saturn’s upper atmosphere. Having survived the traitor star, they returned to the all-too-human tradition of internecine strife. The new city-states of Saturn began to resemble those of ancient Greece, with one group of cities taking on the role of militaristic Sparta...

8. The Sails of Tau Ceti – US$7.50

Starhopper was humanity’s first interstellar probe. It was designed to search for intelligent life beyond the solar system. Before it could be launched, however, intelligent life found Earth. The discovery of an alien light sail inbound at the edge of the solar system generated considerable excitement in scientific circles. With the interstellar probe nearing completion, it gave scientists the opportunity to launch an expedition to meet the aliens while they were still in space. The second surprise came when Starhopper’s crew boarded the alien craft. They found beings that, despite their alien physiques, were surprisingly compatible with humans. That two species so similar could have evolved a mere twelve light years from one another seemed too coincidental to be true. One human being soon discovered that coincidence had nothing to do with it...

9. Gibraltar Earth – First Time in Print — $7.50

It is the 24th Century and humanity is just gaining a toehold out among the stars. Stellar Survey Starship Magellan is exploring the New Eden system when they encounter two alien spacecraft. When the encounter is over, the score is one human scout ship and one alien aggressor destroyed. In exploring the wreck of the second alien ship, spacers discover a survivor with a fantastic story.

The alien comes from a million-star Galactic Empire ruled over by a mysterious race known as the Broa. These overlords are the masters of this region of the galaxy and they allow no competitors. This news presents Earth’s rulers with a problem. As yet, the Broa are ignorant of humanity’s existence. Does the human race retreat to its one small world, quaking in fear that the Broa will eventually discover Earth? Or do they take a more aggressive approach?

Whatever they do, they must do it quickly! Time is running out for the human race…

10. Gibraltar Sun – First Time in Print — $7.50

The expedition to the Crab Nebula has returned to Earth and the news is not good. Out among the stars, a million systems have fallen under Broan domination, the fate awaiting Earth should the Broa ever learn of its existence. The problem would seem to allow but three responses: submit meekly to slavery, fight and risk extermination, or hide and pray the Broa remain ignorant of humankind for at least a few more generations. Are the hairless apes of Sol III finally faced with a problem for which there is no acceptable solution?

Appendix A

While politicians argue, Mark Rykand and Lisa Arden risk everything to spy on the all- powerful enemy that is beginning to wonder at the appearance of mysterious bipeds in their midst…

11. Gibraltar Stars – First Time in Print — US$7.50

The great debate is over. The human race has rejected the idea of pulling back from the stars and hiding on Earth in the hope the Broa will overlook us for a few more generations. Instead, the World Parliament, by a vote of 60-40, has decided to throw the dice and go for a win. Parliament Hall resounds with brave words as members declare victory inevitable. With the balance of forces a million to one against Homo sapiens Terra, those who must turn patriotic speeches into hard-won reality have their work cut out for them. They must expand humanity’s foothold in Broan space while contending with a supply line that is 7000 light-years long. If the sheer magnitude of the task isn’t enough, Mark and Lisa Rykand discover they are in a race against two very different antagonists. The Broa are beginning to wonder at the strange two-legged interlopers in their domain; while back on Earth, those who lost the great debate are eager to try again. Whoever wins the race will determine the future of the human species… or, indeed, whether it has one.
