The Great American Eclipse of 2017

For three years I’ve been talking about this eclipse.  August 21st, 2017 is a date that feels etched into my skull.  With solar eclipses being few and far between, and usually occuring far from my home in Canada, I’m excited that the great american eclipse of 2017 will be within my budget for travel.  Though like many people, I’m ready to pay a bit extra to get to the right spot. The eclipse is expected to draw over 100 million people to the many towns and cities along the path of totality. Though most of the population of North America...

My Three Suns

Not just the title of an excellent Futurama episode, but now a real place.  A planet has been found orbiting in a triple star system, a surprising find that may be more common than once thought. Astronomers from the University of Arizona used the European Southern Observatory (ESO)’s Very Large Telescope (VLT) in Chile to directly image the new planet as it orbits the brightest star in a triple system 320 light years away, in the constellation Centaurus. Orbits like this are thought to be extremely unstable due to the varying gravitational field in the system. “HD 131399Ab is one of the few exoplanets that...

Relative Time: Photography Year 2

Last year after getting a Canon DSLR camera, I spent as much time as I could doing some basic astrophotography.  I took photos of stars, planets, the Moon, and even did some star trails.  One thing I quickly realized is that there are limitations if you don’t have a tracking mount or a telescope adaptor.  The tracking gives you a method for taking longer exposures, and the telescope adaptor as expected gives you the ability to zoom in on distant objects. Even with these temporary limitations (I hope to invest in them someday) there are still a lot of options...

Holiday Lights Make Cities Visibly Brighter from Space

With the extra lights shining in cities across the world at this time of year, we are outputting a significant number of photons into Space.  So many that Satellites in orbit have been able to see the difference.  In the maps below, the areas in green are locations where the brightness has increased by as much as 50%. Being able to see the difference from Space is amazing.  The maps also exist for Caribbean nations, where much of the population celebrates Christmas. Now I’m not avoiding any one particular holiday in my use of the phrase ‘holiday lights,’ because it turns...
