The Trials of Solar Eclipse Photography

Although the August 21st eclipse happened about 6 weeks ago, I realized it would take me a long time to edit all the photos I took during my trip.  I had over 2000 individual shots of the eclipse alone, taking a single (1/4000 s) shot every 10 seconds, at ISO 100, with my telescope coming out at around f/6.  I’ve done a lot of time-lapse photography before, so I thought it would be a routine shot, but I was wrong.  Eclipses are much tougher to edit in terms of a time-lapse. But first, the end result of my 10 hours...

Double Post: Mini Stars & Morning Micrometeorites on Mercury

Alliteration is accessible to all! Okay I’m done. Start some science! Really done this time.  Today’s double post covers the smallest of stars, still larger than most planets, and the only weather Mercury will ever have. Humans are naturally interested in the extremes, the biggest, smallest, fastest, hottest, coldest, and every other characteristic outlier.  With stars, being so huge and powerful, we are often more interested in the largest, hottest, and most energetic.  Though on the opposite end of the spectrum, Cambridge University astronomers have discovered the smallest star in the known universe. The star, a red dwarf, has the...

The Gravity Wave Era

I saw an article last night about gravitational waves, that a black hole merger was detected by not just the Laser Interferometer Gravitational Wave Observatory (LIGO), but by another project altogether, the Virgo collaboration.  This is the first gravitational wave detection confirmed by two separate groups, and it marks the beginning of a new era of experimental science, the first in astronomy in over two decades. Around 1.8 Billion years ago, to black holes merged in a faroff galaxy.  They had masses of 31 and 25 times that of the Sun, though with their incredible density they would each be...

Looking Closer and Testing Theories

Last week, while looking at some of the best images from the Cassini spacecraft, I commented on the fact that the smooth rings of Saturn are small, varied chunks of ice and rock when you get down to the smaller scales.  Reflecting on that this morning, I was thinking about how observing objects in our universe at smaller scales gives new insight into the variety and complexity of natural phenomena.  Not long after, I came across a story of a new interesting object in our own Solar System. A new binary asteroid was discovered.  This in itself isn’t too different...

Water in the Lunar Desert

The environment on the moon is pretty boring.  Rocks, dust, and craters as far as the eye can see in all directions.  Untouched for billions of years, save for meteors and a few recent visits by a blue neighbour.  In 2009, the cold, dry surface of the moon was found to harbour trace amounts of water.  Now, less than a decade later, the first map of lunar water has been produced. The map was produced with data taken by NASA’s Moon Mineralogy Mapper, which flew aboard India’s Chandrayaan-1 spacecraft, the craft that discovered the water in 2009, along with a similar...

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 solar system, originally conceived right after the voyager flyby in 1982, would give us a chance to study more than just a planet, but an entire system of interaction between a planet and it’s moons.  Beyond that, it included the Huygens probe, to land at...

The Eclipse Feeling

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...

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 from a distance of 52,000 Km, has a vivid and chaotic southern pole in the above image.  Swirling storms thousands of kilometres across whirl around one another in a sea of gaseous ammonia clouds.  Will the system remain chaotic? Or will it change a year from...

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 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...

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...
