D A R K S K I E S 9

W hen the cloudy expanse of the Milky Way stretches above us from horizon to horizon, or a meteor streaks across the sky,

or a rocket defies gravity to leave Earth, it touches on a sense of wonder and awe. There is something breathtaking and humbling about the knowledge that beyond the protective layer of our atmosphere, there is a lot more out there. The universe is vast almost beyond comprehension: while technology helps increase our knowledge of moons, planets, and suns, we can hardly imagine how many other places there are in our solar system, galaxy, and the universe once you leave planet Earth.

The natural world on Earth never ceases to amaze us; we make pilgrimages to Everest, Niagara, the Amazon, and countless other awe-inspiring sites on our bucket list. But somehow, the night sky is often omitted from the list of natural experiences we should seek out. Yet its magnificence can be even more overwhelming than terrestrial wonders. For millions of years, the stars have wheeled overhead, and the planets have performed their celestial dance. Observing this pageant used to be a nightly ritual for humans across the planet until very recently. But while we often book trips to explore new cities and try new foods, we rarely do the same for astronomical phenomena and space experiences. We may have gone stargazing as a kid or learned about astronomy in school, but we don’t journey to discover it firsthand. In not seeking out encounters with astronomical phenomena, whether at the certified dark sky parks listed in this book or by viewing a meteor shower or eclipse, we deprive ourselves of a magical experience. Less than one hundred years ago, seeing the unobscured

Early contributions by civilisations like the Sumerians, Babylonians, and Indians are still used in astronomy today. Over the centuries, the amalgamation of work by Chinese, Islamic, Egyptian, and European astronomers helped solidify astronomy into a scientific field in its own right. During the medieval era, astronomy was advanced significantly by the work of Islamic astronomers. While astronomy was actively practiced in Asia, Islamic astronomers helped with the translation from ancient Greek to Latin of fundamental astronomy texts by thinkers including Aristotle, Euclid and Ptolemy. As a result European astronomers were able to recommit to the science of astronomy that was at risk of being lost. Islamic astronomers also created some of the most accurate calendars, predictive models, and recorded observations of astronomical phenomena in human history.

Later, Renaissance astronomer Nicolaus Copernicus helped initiate the Scientific Revolution which fundamentally shifted human understanding of astronomy and science in the 15th and 16th centuries. While the idea of a heliocentric universe had been proposed centuries before by the Greek astronomer Ptolemy, Copernicus’ reassertion that the Earth orbited the sun became one of the most controversial ideas of human history. Physicists and astronomers including Galileo, Kepler, and Newton helped drive forward our understanding of the universe using this new model.

After initial resistance by the Catholic Church, the Copernican theory was accepted and knowledge about astronomy and astrophysical principles began to receive global consensus. The Copernican revolution came to its natural conclusion with the discovery of a series of scientific laws that helped us understand the night sky and our place in it. Between the 17th and 20th centuries, the rate of discoveries by observational astronomers

night sky was a birthright; now it is inaccessible to urban and suburban residents across the globe. Yet it's still in reach if we seek it out.

What drives our collective interest in the night sky? It’s likely the case that the roots of astronomy lay deep in the prehistoric era, among the first Homo sapiens who became aware that the movements of the sun, moon, and stars were not random. In an attempt to find significance among these patterns, religious beliefs were established to help make sense of the natural phenomena. These religious beliefs remain closely tied to astronomy to this day, as reflected by the practice of astrology (the idea that the movement and placement of stars and planets have a direct impact on our daily lives).

A more modern interpretation might also say that though we did not always know with scientific certainty that there was ‘more’ beyond Earth, our human nature to explore and colonise drives us to look toward the stars. In the 21st century, it’s likely that our efforts and investment will take us to other planets in our solar system at the very least. While we have spent centuries learning about the night sky, our time exploring it has only just begun.

The most easily accessible way to enjoy the night sky is by stargazing, looking up at the constellations and planets visible either with the naked eye or through a telescope. Astronomy dates back nearly 5000 years, to the Bronze Age. While there aren’t many records from this time, archaeoastronomers have discovered evidence and relics that suggest that from among the earliest periods in human history, we were attentive to the night sky and attempted to record the patterns observed there. Nearly every major civilisation at one time was involved in the study of astronomy. Major sites testifying to the astronomical knowledge of earlier cultures remain in the Yucatan, at Uxmal and Chichen Itza; at Chaco Canyon (p94); and at the pyramids of Egypt, Stonehenge, and more.

increased exponentially as the astronomical objects and phenomena laid out by these new laws was confirmed. Findings included the discoveries of planets, moons, asteroids, and comets in our solar system as well as more distant galaxies, nebulae, exoplanets, and black holes. New observing technology developments accelerated our rate of discoveries too. First invented in 1608, simple telescopes became increasingly powerful at observing the heavens. While there continued to be disagreement in reconciling religious and scientific beliefs about the solar system and universe, these were for the most part relegated away from the steady advancement of human knowledge of planets and moons, asteroids and comets, nebulae, supernovas, and galaxies.

During the 20th century, massive strides were made to improve astronomical technology for observing the skies, and our theoretical understanding made similar strides after Einstein’s breakthroughs around General and Special Relativity. The light we see from the stars and planets has to travel across space to reach Earth; as a result, understanding how light moves is fundamental to understanding astronomy. Building on the massive legacy from civilisations and centuries of astronomy, scientists have been able to ask the deepest questions about the origins of the universe – and have begun to craft answers based on the observational data and theoretical models we have developed. As the 21st century continues, we are closer than ever to understanding the night sky, but still have a lot we don’t even know to ask. When we look up at the stars and galaxies in the night sky, we are seeing the death of old stars in supernova, the birth of new ones in stellar nebulae (also sometimes called ‘nurseries’), and in some cases, the impacts of invisible-to-us black holes on the space around them.

Even the space race of the 20th century was in part driven by the pull we feel to reach the stars.

Milestones such as putting the first man in space or reaching the moon were meaningful because they took significant steps beyond our planet – the place we have called home for millennia. The human race to space has continued to launch satellites, orbiters, space telescopes, and rovers to explore deeper into space to better understand how the universe works.

The latter half of the 20th century and early 21st century has also seen the rise of the dark-sky preservation movement. Driven by international organisations like the International Dark-Sky Association, national bodies like the Royal Astronomical Society of Canada, and local institutions and advocacy groups, there is an increasing focus on preserving the dark sky where it is still visible, or in some cases reverting back to darker skies through infrastructure planning and lighting replacements. Many of the locations mentioned in this book are destinations focused on dark-sky preservation, and some have received designations for their work preserving the darkness. If you think you’ve seen the night sky but you’ve never witnessed it from a location with a truly dark sky, you’re in for the surprise of a lifetime.

The skies above us are part of our heritage, both natural and cultural. Astronomy and stargazing are an important part of human history, one that can connect us back to early myth or awaken us to the vast scale of our universe and its many mysteries. Witnessing the sweep of the Milky Way, the remains of passing comets as they burn up in our atmosphere, or the shimmering aurora, we better understand space and our place in it. This book will help you experience all of this and more first-hand, so that you can glimpse some of the celestial wonder yourself. Taking time to enjoy the heavens, whether on travels abroad or from the backyard, deepens our knowledge and appreciation for our planet and the universe as a whole.©

Many people learn to stargaze as a child when their parents

or teachers point out some of the most famous stars and constellations in the night sky. While the names of these stars and constellations might vary depending on the culture or time you grew up in, they’re a good foundation for stargazing later in life. If you didn’t grow up with an opportunity to stargaze – either because it wasn’t taught or because you lived in a city where stargazing wasn’t possible – now’s the time to begin. Stargazing is one of the easiest ways to enjoy nature here on Earth: all you need are your eyes and dark skies!

Before you go stargazing you may want to do some research on the constellations visible in the sky above you, depending on your location and the month. The good thing is that the movement of celestial bodies in space is predictable, and there are powerful tools to show you what the night sky will look like before you start stargazing (or historically, if you’re

Quick Definitions

Comet: A small solar system object comprised primarily of ice, but which may also have dust and rocky particles in it

Asteroid: A small object comprised primarily of rock, usually from within our solar system but sometimes from beyond it

Meteoroid: A very small space object made of rock or dust, bigger than a molecule but smaller than ~330ft (100m) in diameter

Meteor: A meteoroid that has come into contact with Earth’s atmosphere

Meteorite: A meteor that passes through Earth’s atmosphere without burning up and makes impact on Earth

Meteor showers are a visible record of astronomic life in our solar system. Caused by comets and asteroids that leave trails of debris as they

transverse Earth’s orbital path, the detritus shed by these comets and asteroids on their journey flames out in glory when it meets Earth's atmosphere. Each year, Earth crosses those trails on the same schedule, to the delight of meteor watchers. As the planet passes through one of these fields of debris and a meteor shower occurs, it’s a reminder that there are many objects in our solar system, moving around and dancing in sync without stepping on each other’s toes. In fact, meteor showers occur on every celestial body as the planets, moons, asteroids and comets move in their celestial dance.

As Earth crosses the paths of cometary debris, it enters the atmosphere at a higher frequency than one-off objects entering the atmosphere from space. Watching these spectacular shows doesn’t require anything more than the right timing: they’re visible to the naked eye. When small objects hit Earth’s atmosphere, we see these meteors light up as so-called shooting stars as they burn up on their fiery passage. While ‘shooting star’ may be a misnomer for the event, which is unrelated to any stellar phenomena, there’s no denying the magic of seeing a bright object arc across the night sky.

Meteor showers are typically caused by comets, and less commonly by asteroids, but what’s the difference between the two? Comets, which are responsible for the majority of meteor showers, are small solar system objects that are comprised primarily of ice and dust. They may also have an atmosphere, or tail, made of ice, dust and rocky particles. Comets in our solar system typically originate in the Kuiper belt, beyond Neptune. Asteroids, by contrast, are considered ‘minor planets’ in our solar system and have a rocky,

mineral core. Typically they orbit the sun in a similar way to the other planets, and there is a large asteroid belt between Mars and Jupiter where most observed asteroids can be found. Some asteroids merely travel through our solar system on their journey, but these are less likely to leave a debris path notable enough to cause an annual shower.

Some meteor showers occur on a regular basis, including the majority of those in this section. There are also ‘periodic’ meteor showers, which occur less consistently: some years they may be very active, whereas in other years there may be no visible meteor behaviour at all (the Draconids are one such periodic meteor shower). Additionally, meteor showers are generally visible in parts, but not all, of the world, depending on the position of the debris path. It's their very unpredictability and brief lifespan that makes them so magical to view.

To see a meteor shower, plan to view in the hours between midnight and dawn. Most showers will experience the greatest visible activity at that time since the skies will be dark and most radiant points will be higher in the sky. But while there is a radiant point, identified as a constellation or collection of stars that meteors seem to appear from, don’t look directly at it when trying to view meteor showers. You’ll have a better chance of seeing meteors if you look in the space around the radiant point and, in some cases, throughout the whole night sky (as with the Leonids). It’s optimal to try to view a meteor shower on its peak days, when the most meteor activity will occur; there are often forecasts available from NASA ahead of time that provide more detailed estimates. Increase your chances of seeing a 'shooting star' by planning ahead, but be aware that the dates may shift by one or two days on any given year. Always avoid nights with a full moon, or observe before the moon has risen or after it sets. Oh, and don’t forget to make a wish! ©
