Of course, there is that scene in Cosmos where Carl Sagan is sitting on a beach somewhere and talking about the stars. He picks up a handful of sand and says that the number of grains of sand in his hand is about as many as the number of stars you might be able to see unaided if you looked up at a clear night sky. He then says that modern cosmology has shown that there are more stars in the universe than all the grains of sand on all the beaches of the world.

This is a book about what happened w
One day in 1925 :

Hubble : The universe is bigger than everybody thinks.

A humbler astronomer invented for the purpose of this review : Yeah? How big are we talking?

Hubble : Well, you know the Milky Way? Okay, now see through this telescope, see those little wispy things there?

Astronomling: You mean those spiral nebulae?

Hubble : Well what if I told you they weren’t spiral nebulae?

Little astronomer: Aww, you mean they’re just smudges on the lens? Damn. We wasted a lot of time on those things.

This book is a fantastic, popular-science history of a pivotal era in astronomy: the moment in time when we went from a belief that the Milky Way was the Universe entire, to the knowledge that the Milky Way is but one galaxy in a Universe comprising billions of others.

Both the famous names (Hubble, Einstein, etc) and the less well-known players (Vesto Slipher, Milton Humason, Georges Lemaître, etc) are represented in this fascinating, well-written, and well-researched book.

I can't even imagine what it would have felt like to have seen some of these early images of the expanding universe during this time but it must have been completely inspiring, and if any book gives you a glimpse into what this must have felt like this book is it. It contains an assortment of well known and less well known but equally important contributors to Astronomy in the early 1900's leading towards today. It really makes you look differently at the giants of this time such as Edwin Hubble ...more

This book provides a virtual front row seat to the discoveries of facts about the universe that were bigger, stranger, and more spectacular than anybody could have imagined at the beginning of the 20th Century. Today the newness has worn off of such terms as expanding universe, space-time continuum, and multiple galaxies. So it's good to imagine the excitement that must have been felt when these words were first uttered. If these concepts seem unfathomable now, they were even more unbelievable t ...more

Oh, to have been an astronomer in the heyday in the early 1900s. I've always wanted to be an astronomer (was never good in physics). Now I know what time I would have ideally wanted to be one. Everything was new...the telescopes, the country, the skies were free from light pollution, and the glory of discovery. Oh, to dream.
A dramatic and wonderfully written book about a special group of scientists that shaped our knowledge of the universe, in turbulent period at the beginning of the 20th century.
It follows their lives, their work, their battles of ideas, theories and calculations that inflated our universe from our solar system and Milky Way to the ever-expanding vastness filled with countless galaxies.
Meet the scientists that searched for their answers among the stars, people like James Keeler, Heber Curtis, Hen
This is easily the most interesting book that I've
read this year and I've read quite a few. Please
don't shy away from it due to a fear that it might
be a difficult read, it's totally accessible and
requires no prior knowledge of astronomy &c.

The action really starts just prior to 1900 and
continues on for the first three decades of that
century, a period that revolutionized our under-
standing of the Universe, its structure, extent
and our place in it.

Einstein's is a name familiar to all of us, an
the title of this book should be changed to "The entire history of star gazing PLUS the entire backstory of every person that ever had a telescope in their life AND (maybe) the day they all got together"

i did not finish this book. i made it about halfway through and it was the most boring thing ever! i was expecting a book about a single day and some in depth knowledge on that day and some stuff about astrophysics and scientists who i have heard of and who i havent.

well, this is not that. and i
Before the first world war the universe was not much bigger than the Milky Way. Every pinpoint and smudge of light that could be seen through the best telescopes of the time were believed to exist within the confines of our own galaxy. During the decade after the war, all that changed when Edwin Hubble came to Mount Wilson to peer at the night sky through the 100 inch reflector. By 1930, we new that the universe was made of innumerable galaxies speeding away from us at every increasing velocitie ...more
In the 1920s we found out that the universe is much bigger than we thought and getting bigger. The main person who generally gets the credit is the American astronomer Edwin Hubble, who worked at the Mount Wilson observatory near Pasadena, California. Hubble's contributions were important but not the whole story. Vesto Slipher, an astromer at the Lowell Observatory in Arizona, had noticed that the light from what were then called spiral nubulae were mostly Doppler shifted to the red end of spect ...more

Terrific insight and careful explanation about how the universe was discovered. Wonderful anecdotes, background information and buildup to Einstein's acceptance and confirmation of it all. Hubble plays a major role but all the characters and their roles are laid out and explained. No complex math. Any layman with a high school education could read this book and leave it fully enlightened about the universe they live in.
Billie Mulcahy
Beginning in 1888, with the construction of the Lick Observatory on Mount Hamilton in California, to the Mount Wison Observatory, with its 100 inch telescope where Hubble discovered, in 1925, that there were other galaxies, Bartusiak describes the many astronomers and the advances in telescopes that lead to Hubble's discoveries. The story begins with a wealthy man, James Lick, who wanted to build a monument to himself, and decided to build a marble pyramid that would have been larger than the py ...more

Recommends it for: anyone interested in learning how we discovered the size of the Universe
A very interesting book. I have to admit that when I first started to read it, I found the writing very dry, and only my interest in the subject kept me reading. I'm not sure whether the writing improved throughout the book, or if I became used to her writing style, but by the end I loved the book. I hope she writes a continuation covering the discovery of the Big Bang theory, and the astronomers involved in that discovery.

The author starts off talking about each astronomer and their discoverie
If you care about how we learned what we know today, then the history of science is important and you will like, probably love, this book. A complete and well-told story of a branch of astronomy featuring Lick Observatory (the first built at high elevation), the infancy of space photography, spectroscopy, and all the contributions that led to Hubble's seminal work in the 1920s. A great illustration of how the scientific method produces new understanding. it made me humble: it's easy to mock peop ...more
Gave this five stars even though I didn't find it engrossing in many parts. Purely for the information it provided me. It did its job as an educational historical science book.

Fun popular history of astronomy in the 20th century, written in a very lively style. Good enough I bought a copy for my father for Christmas!

A wonderfully well-writen, well-researched, extremely interesting and cativating account into the story of the people who contributed for our understanding of the universe.
This was a very interesting account of how scientists discovered that the Milky Way is not the only galaxy, and that the universe was much, much, larger than thought. It was like a great detective story, with many false leads, egos and missed opportunities along the way. When Hubble ocnfirmed that nebulae were actually distant galaxies, this resulted in eventual unerstanding that the universe was TRILLIONS of times bigger than estimated prior to this. This line is int he introduction and stuck w ...more

I read this a while back lent it to a friend who also found it an excellent book. When I read it again I'll add more details.
Challenging enough to teach one something, and be worth one's time. Very clear in explication. In the early 20th century we learned that the universe is much larger than we at first thought. Edwin Hubble was the dashing, romantic figure who proved it, but Marcia Bartusiak doesn't slight the other important figures who were part of the discovery. Bartusiak's explanations are clear and straightforward, and additionally, she is a very nice lady. Don't miss her Thursday's Universe.Thursday's Univers ...more
Oh my god. I started this book two and a half years ago and I finally FINALLY finished it. It was extremely interesting leading up to Hubble. In the "Adonis" chapter, where the author introduces Hubble, I completely lost interest. I disliked Hubble's persona and arrogance which put me off finishing the book for so long. I've been reading so much physics and cosmology lately though, I just couldn't leave this unread any longer. I got through my personal distaste of Hubble but focusing my attentio ...more
Great historical recounting of the history of astronomy.
Picked this up at the gift shop at the Griffith Park Observatory (great place to visit BTW). This is a fascinating and engaging story of how Edwin Hubble proved that we weren't the only galaxy in the universe and about all the players that came before him and contributed to what he ultimately determined. The astrophysics wasn't too difficult to keep up with, and the the story of the cast of characters was interesting. Good, easy read
Very well done popular history of the state of astronomy research in the late 1880's to pre-WWII. The title refers to Hubble's paper, released in early 1925, verifying that there were other galaxies (aka island universes at that time) than our own Milky Way. Great capsule biographies of several of the major players, such as Shapley and Hubble. Highly recommended.
There was a lot to like about this book. It told the history of astronomy leading to the realization that the Milky Way is just one of billions of galaxies and is not the center of thing. Biggest surprise was how huge a role Lick Observatory played in this. Disappointed that the author didn't recognize that lots of good work is still going on there.
For someone who may not have the slightest background in astronomy and only the basic knowledge of who Einstein was, this book does a wonderful job of describing the fascinating science behind the discovery of the universe as we know it today.
Ms. Bartusiak is a wonderful author and truly painted a more meaningful picture of the night sky.
In depth survey of the scientists and lay people whose works combined to measure the distances to the galaxays. Thus opening a new vision of our place in the universe.The story is well known, but some of the lesser known people are given their due.

I've always enjoyed Marcia Bartusiak's science writing. This one is no exception.
A thoroughly interesting history of the story of the beginnings of many observatories in the U.S. and particularly California. For me, the (local) information on Mt. Wilson and the astronomers who worked there, their relationships and how many astronomers' discoveries were not believed or put aside was particularly interesting.
I found this to be an excellent run through of our findings about the universe up to this point - I feel like I have a better understanding of how we got to our current model. There was also just enough humor to prevent me from getting bored. Yay! ^_^
