A Surprising Pan

You’d think I would have learned my lesson by now.  Every time I think I’ve seen it all, that I’ve seen every strange phenomenon in space, every unique planet, moon, star, galaxy, every variation, I’m proven wrong.  I expect that the order has been established and everything newly discovered will fall into a category with […]

Einstein’s Final Riddle

Why does the Universe expand the way it does? Why does it accelerate? Einstein’s equations offer an explanation of gravity that works on the scale we know, but does it work on the grandest scales of space and time? Humanity now has a way to find out. The General Theory of Relativity predicts the behaviour […]

Geostationary Revolution

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 […]

Astrophotography: Sagittarius and the Galaxy

The challenge of learning astrophotography, and photography in general, is two-fold.  There’s the work you do at the eyepiece, requiring you to choose the right settings for the right shot.  Then there’s the work you do at the computer screen, the post-processing and adjustments.  Ultimately the more important one is the camera work.  If you […]

Measuring Dark Energy Like a BOSS

When you start to think about the most massive and extreme ‘stuff’ in the universe, you inevitably go to Dark Matter and Dark Energy.  They exist as opposites, one with incredible gravity holding the universe together, and the other a mysterious vacuum energy tearing it apart.  Studying this cosmic tug of war gives astronomers a […]
