Heavy Metal

Where do the heavy elements on the periodic table come from?  The general answer is from what’s called the r-process of stellar nucleosynthesis.   This translates to ‘rapid neutron capture’ being the method by which most of the elements heavier than Iron are formed on the periodic table.  This process requires immense energy and was originally […]

How Life on Earth Began

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 […]

Mars in the Spotlight

On May 22nd, Mars will be at opposition.  It’s the astronomical term for when Mars and the Sun are on opposite sides of the Earth.  This makes the face of Mars fully illuminated from Earth, and also brings the Earth to it’s closest approach of Mars, at 75 Million Km.  Hubble images the red planet to […]

Europa Chemistry

I always get giddy when talking about Europa, as many astronomers do.  It’s one of the most fascinating places in our solar system when it comes to the search for life.  It has lots of water, likely contained in a subsurface ocean.  It’s heated though a gravitational tug of war with Jupiter and the other […]

New England Fireball

Space dust hits the Earth every day in the form of meteorites. As much as 300 tonnes of the stuff falls to the Earth each day.  Of course, most of it is dust or small rocks, and goes unnoticed by the majority of people.  But every so often, a larger rock plummets to Earth, and […]

The Next Canadian Astronaut

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 […]

Review: Planetary

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 […]

Review: IMAX: A Beautiful Planet

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 […]
