2024 Reading Challenge #9: More Than 5 Words in the Title
2024 Goodreads Challenge - Book #19/25 (Last book of the year T^T)

Thiiiiis I downloaded on kindle to try and kinda get through my reading goal with short books. It wasn't exactly what I thought it was going to be, though. I thought it might go more in-depth discussing the mythology behind the night constellations and things like that. I did learn a few interesting things, though. Like the fact that I'm younger than a Saturn orbit!!! That makes me feel good. In fact, Saturn will complete one of its 29.5 years long orbits in approximately March of this year which is kinda cool, congrats in advance for completing a lap finally Saturn <3

It was fun coming back to this book every few months this past year to learn about the constellations of the season. I also enjoyed learning about the mythology behind each constellation and the meanings behind the names of stars (so many of Arabic origin!).
It does get very repetitive though just because of how the entries are structured: first a page on the constellation, then a page on the main star in that constellation which has almost all the same information. So it might be better to just use this book for reference rather than read it sequentially. The language is also a bit childish but that's on me for not realizing it's a kid's book hahaha
My favorite memory from reading this is the time I was stargazing with my friend and happened to be open on the exact page that showed us what we were looking at (the summer triangle) 😊

In this basic guide to stargazing, readers will discover some basic information about the sun, the moon, and the planets that are visible without a telescope. Then they will explore the stars and the constellations in the northern sky, the winter sky, the spring sky, the summer sky, and the fall sky.

Discover man-made objects in the night sky; then learn about meteors and meteor showers.

Follow that with other astronomical events, including lunar and solar eclipses, planetary conjunctions, comets, auroras, and more.

Explore the night sky and explore planets, satellites, meteors, and constellations using this basic guide to stargazing. You’re sure to discover something new every night.

=========

After a brief introduction and a few pages of “How to Use This Book” instructions, this book helps beginning stargazers discover what they can see using their eyes or a small telescope. Designed for readers new to stargazing, this book focuses on helping stargazers develop a foundation of knowledge about the night sky rather than providing detailed information.

Easy-to-follow instructions and detailed star maps will help the novice stargazer identify a variety of objects in the night sky. Happy stargazing!

Highly recommended.

100 Things to See in the Night Sky is a guide by Dean Regas, published in 2017 and updated in 2020, that teaches/helps people locate various objects in the sky. The objects are those that can be seen in the Northern Hemisphere at different times of the year. It begins with the simplest objects we see every day-- the sun and the moon. In the discussion of the sun, Regas talks about how to safely observe it without damaging your eyes. He also talks about the best times to observe the moon through binoculars or a telescope, and what to look for when you do. He then discusses the planets visible to the naked eye, followed by various constellations and the stars that form them. He also mentions some deep sky objects that would require binoculars or a telescope to see, such as the Andromeda Galaxy and various star clusters, and how to find them relative to the constellations. He concludes with a discussion on observing things such as comets, meteor showers, and even satellites.

The hardcover version of the book is a little under 250 pages long, but it has a lot of photographs and illustrations, so it is not 250 pages of actual text and reads quickly. Regas does an excellent job of detailing where to look for the various objects he discusses, as well as providing a short history of how they were first discovered (for those there are a record) or the stories behind how they were named. Ultimately, it is a fascinating book that is perfect for amateur astronomers. It is absolutely worth reading.

This is something of a bird book for heavenly bodies: it briefly describes some of the prominent or important ones, and gives some lightweight advice on watching them, but doesn't give much of an understanding of their inner workings or life cycles.

It's frustratingly light on details. Mr. Regas writes "Many people think the Big Dipper is a constellation, but it's actually an asterism, a recognizable shape of stars." Aren't constellations also recognizable shapes of stars? Does the distinction point to clusters of stars that are physically near each other versus those that are merely in the same general direction from our perspective on Earth? (The answer appears to be that constellations are asterisms that have been officially recognized by the IAU.) The effect on this reader is that of a guy at a party who begins a recognizable fraction of his sentences with "well, actually". Technically may be the best kind of correct, but it doesn't make for a satisfying read.

Perfect for any Northern Hemisphere aspiring astronomer, or any excited stargazer!

As a child, I was always interested in the night sky; the moon, the planets, meteors (and especially extraterrestrials). I was two classes away from a minor astronomy degree (but had to use all my later class time for business :( ). This book is packed with not only 100 interesting things to see in the sky, but cool facts, histories, and myths surrounding them. If you like Greek and Roman mythology, you'll like this book. And other stories and names of stars come from lots of different cultures around the world. Then on top of that, the book tells you the best times, places, and locations to see each of the 100 things, and tips on how to find them and reference points to make sure you're looking in the right location. It's so useful you'll almost wish you had a pocket-sized version that you could take with you and your telescope out to the country with less light pollution. While reading it page-to-page like a novel may give you a lot of repetition of information, it's incredible useful as a guide and refresher to learn-up on whatever new constellations and heavenly bodies are in view on any given night.

A nice introduction to stargazing. The book was accessible and easy to understand. The diagrams of the constellations were helpful, as were the directions as to how to find them in the night sky. I also liked learning about the mythologies that previous cultures have ascribed to the constellations and planets, it made the book very enjoyable to read.

I feel as though I’ve gained a more thorough understanding of the stars, planets, galaxies, and various celestial phenomena that grace our skies. A nice jumping point for more in-depth research!!

I work in space physics in my day job, and I picked this book up at Five Below ($5!) hoping for a nice resource for friends and family to navigate introductory astronomy topics and pique their interest. This book did not disappoint! It is excellent for introducing the night sky to beginners, and I learned a few things myself!

A beginner-friendly book . Easy to read and digest. And a reference for constellations and stars for beginners . As a beginner, you need this book with little knowledge about celestial coordinates and dive into the wonders of universe.

It’s a truly formative book on Astronomy. The only drawback from my side is that’s oriented to people who live in the Northern Hemisphere

Awesome book to understand the myths around most popular constellations. Funny and beautifully written, I wish there were more books like this one.

Recommended for anyone starting to spend more time with the stars.

I’m pretty impressed with this book. It’s small enough to tuck into a bag with the rest of your astronomy equipment, is formatted in a clear, simple style with only a few useful star charts for finding and orienting yourself with the constellations, and is printed in a dark blue ink that will result in great contrast when viewed under a red astronomy light. Even the binding seems to be unusually sturdy.

After a half dozen pages with some useful information to help beginners get started, Part 1 covers the sun (including how to view the sun safely), the moon, and the planets that can be seen with the naked eye (Mercury, Venus, Mars, Jupiter, and Saturn). Each entry includes What Is It?, a difficulty level (easy, moderate, or difficult), and a description, as well as some interesting things specific to that object (moon phases, transits of Mercury, the ring tilt of Saturn, etc.).

Part 2 is the largest section and covers stars and constellations (it also includes some star clusters, a nebula, a galaxy, and a few asterisms), organized by the season in which they are best seen, and another group that are visible year round in the northern sky. Each entry includes What Is It?, a difficulty level, a description, as well as directions how to find it. These directions are based on easily identifiable objects and patterns in the night sky rather than right ascension and declination. This makes it easy to really learn your way around the night sky rather than relying on the numbers. Plenty of time for that later.

Part 3 covers a variety of other objects, including satellites, meteors, auroras, eclipses, and more). The basic layout is the same as Part 2, and a list of dates is given for future total lunar and solar eclipses in the U.S. (some of the lunar events have already occurred).

The level of detail isn’t overwhelming, which is a point in its favor for beginners. Some of the information includes relevant history, mythology (did you know that Taurus was painted 17,000 years ago in a cave in France?), and some basic facts about astronomy. It’s a well-balanced introduction to the beauty of the night sky and very easy to read without getting bogged down in too much detail. Even better, everything in here is easily within reach with only modest equipment. If you’re lucky enough to live in or have access to dark skies, you can see most of these with the naked eye or a modest pair of binoculars.
