As I often do, I pulled up the Astronomy Picture of the Day, and noticed today’s photo was a fond reminder of the eclipse I witnessed a month ago. I began to think about the preparation and timing, planning and organizing, the countless hours of testing gear for a single moment lasting two minutes, where the Moon and Sun aligned. I was in the right place, at the right time. Solar Eclipses are rare, and it’s mostly because only a narrow band of land on Earth, usually around 100 Km wide, experiences such an event at any one time. And with...
It was like someone turned down the Sun with a dimmer switch. The tempurate dropped quickly, enhanced by the lack of moisture in the dry mountain air. In a span of an hour, the Sun looked the same, but was very different, as totality approached. I was taking photos through my telescope with an attached solar filter, so I could see the Moon slowly covering the Sun. But as the environment changed in Northern Wyoming, I grew more excited for what was to come. Over a year of preparation for this event, and clear skies greeted me with the confidence...
For 4.5 billion years, life evolved on planet Earth. Not once were the inhabitants of this tiny blue mote of dust able to gaze upon their home as one entity. To them it had always been an endless land without borders and an endless supply of food and resources. Most of them were blissfully unaware that they could ever venture further, and so they accepted the boundaries of their existence unquestionably. Once humans started making tools, we were taken down a path of discovery that would let us escape the bounds of our shrinking world. Finally, just over 70 years...
One of the reasons I love science is that it actually does allow us to look into the past and future, beyond our existence in the present. Written history gives us a perspective of a person who was around before any human currently living on Earth, and allows us to piece together the history of our culture. This is very important, so no disrespect to historians and their work. Much disrespect to fortune telling though. It’s a waste of energy involving a person who fishes for information for a living. But let’s talk about Science. Since we just passed Canada...
After a relatively long hiatus, I am back blogging. I am currently more than 22 posts behind my “post every day” goal, so expect some short and sweet posts to make up the difference. I’m not worried about it, because life gets busy, and we all have other priorities. But I’m glad to be back. A true love of Astronomy and Space will always keep me here, writing about the new and exciting science in a field I have loved my whole life. If you, reading this right now, are the only person who ever reads these words, I hope it adds...
One of the most important questions our species has tackled is the origin of life on Earth. If we can figure out the conditions and catalyst for the beginning of life, we can look elsewhere in the universe for those same conditions, and zero in on the potential for finding extraterrestrial life. We know the universe is old enough for the painstakingly slow evolutionary process, but what started it? In the famous 1952 Miller-Urey experiment, a flask containing the basic natural elements water (H20), methane (CH4), Ammonia (NH4), and Hydrogen (H2), all present on the early Earth, was subjected to...
This guy is everything you expect in an astronaut. At least that was my first thought when I was looking at his biography. David St. Jacques was one of only two candidates (along with Jeremy Hansen) chosen in the 2008 Canadian Astronaut draft, the third in our nation’s history. He has a degree in Engineering Physics, a Ph.D. in Astrophysics, and is a medical doctor. And that’s just his formal education. He’s an avid mountaineer, cyclist, skier, and sailor. Not to mention his advanced certification as a scuba diver, his commercial pilot’s license, and his ability to converse in Russian, Spanish, and Japanese. And so...
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,...
Life in the universe is a fascinating topic. The simplest question: Are we alone? It breeds so many deeper and more profound scientific questions, like “How many habitable planets are there?” “How likely is life to develop on any given planet?” and “How long can a civilization survive?” We can’t answer them definitively, but we can narrow it down. The Drake equation, shown above, was first developed by Frank Drake, the head of the Search for Extraterrestrial Intelligence (SETI), in 1961. He took the question of are we alone and made it quantifiable, in a probabilistic way. It lets us...
Mice are a common laboratory animal for pre-human testing. Everything from drugs to medical treatments to surgeries have been tested on mice, and the effects of spaceflight are no exception. Animals such as Laika the dog and Rhesus monkey Albert 1 have had their own test flights, but mice offer an easy alternative when there’s not much extra room on a spacecraft. In a recent study, mice flown on the space shuttle Atlantis were shown to have developed early signs of liver disease. Could humans in space exhibit the same symptoms? “Prior to this study we really didn’t have much information...
