This post is a collaboration with my good friend Bob Wegner, a professional musician, amateur astronomer, and genuinely good person. With the New Horizons spacecraft passing Ultima Thule on New Year’s eve 2019, Bob and I noticed that Queen guitarist and astronomer Brian May was on hand for the live event, playing a newly-written song to mark the event. Bob and I often talk about astronomy, as I’m always interested in his perspective as an enthusiast, while he’s equally interested in my opinion as a professional. We decided to take this event and write about it from two perspectives. For...
On the heels of my last review, I watched another movie with a space-documentary theme. Though it started out with the human perspective from space, it progressed into so much more. This is the TVO documentary called Planetary. It began with Apollo. Humanity broke the bonds of our world and set foot on another heavenly body. For the first time, we could look back and see the world as it truly is. One of my favourite quotes from the movie came up early, though I’m paraphrasing: We are the Earth, and the Earth is all of us. Seeing the Earth...
I recently had the opportunity to watch a brand new IMAX feature, called A Beautiful Planet. It features incredible views of the Earth from space, captured by astronauts aboard the International Space Station. Most of the footage was taken during Expedition 42 on the ISS, starting with the arrival of Samantha Cristoforetti, Terry Virts, and Anton Shkaplerov aboard the Soyuz TMA-15M, and ending with their departure. Much of the film was focused on the views of Earth, the scenic diversity of life and land that can only be seen from space. It was difficult to see the effects of humans during the day time,...
One of my first books on Astronomy was about the planets. It had a collection of pictures from the first missions to each of the worlds in our solar system. Seeing those photos, the planets felt so alien, so different, and the perspective was like something out a 1950s science fiction comic. But now, with modern advancements in imaging technology and rocketry, we can send heavier instruments to distant worlds, and see them in high definition. It changes the perspective and makes the world seem more familiar than alien, more livable and real. Take a look at the first picture...
When we see the Earth’s only Moon up in the sky, we often think about how small it is. It’s only about 1/4 the diameter of the Earth, and at a distance of 384,000 Km, it looks small in the sky. But often size is entirely a matter of perspective. What we compare something to, that’s what determines it’s size. When the Moon is high in the sky we easily compare it to the size of the window we are looking through, or to a nearby tree, or our outstretched hand. All of this can make the Moon seem pretty tiny....
As 2015 wraps up, I wanted to share one of my favorite quotes and perspectives, from none other than Carl Sagan, arguably the greatest science communicator in history. “Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love,...
When I became a Masters student, a big part of the reason I liked the supervisor I had was that she studied M31: The Andromeda Galaxy. Since I was young I was obsessed with finding this galaxy in a telescope, and I will never forget the night I first found it. Seeing that strange fuzzy patch, photons that had travelled for 2.5 Million years through space, it was my first ever experience with ‘time travel’. Consequently, it makes sense that I am excited about a recent Hubble release: the highest resolution photo of the Andromeda Galaxy Ever taken. Let’s start...
Pictures can say a thousand words, and the Astronomy Picture of the Day from NASA usually does. Today’s photo shows massive perspective, from the ground a pretty large observatory is visible, yet it pales in comparison to the vast mountain range in the background. Further still is the structure that makes all human experience seem minuscule: The Milky Way Galaxy.
You need to see this animation. It’s an amazing picture showing the Hubble Ultra Deep Field and the small patch of sky Astronomers had to aim at in order to photograph it. The moon is there for comparison. The patch of sky is about the size of a grain of sand held at arm’s length. Courtesy of gfycat.com, it really puts things in perspective. The crazy part is that if you look in any direction in the universe, in patches of sky as small as this one, you see the exact same thing. There are more galaxies in the Universe than we...
