Cassini – A Fond Farewell

I remember vividly my first astronomy class in university.  Winter 2004, only months before the Cassini spacecraft was set to arrive at Saturn after a seven year journey.  On several occasions in that class we talked about what we might see when Cassini reached it’s destination.  The first dedicated mission to the jewel of the […]

Juno’s New Jupiter

The Juno spacecraft began its long journey to Jupiter in 2011.  Waking up in 2016 it underwent a successful orbit injection on July 4th. Now after nearly a year of waiting, the public finally gets to see the first fruits of the mission. It has certainly been worth the wait.   A new Jupiter, seen […]

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 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 […]

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 […]

Moon Size

I hate the term ‘supermoon’. In fact that is the only time I’m going to use that term during this entire post.  The Moon does appear a tiny bit larger in the sky, but it’s not an uncommon thing.  Here’s why this one was particularly good at driving headlines. The technical term for the full […]
