Welcome to a new series of posts that will characterize 1000 amazing facts about the Universe. There is so much out there that we have yet to learn, and every day, astronomers across the globe are using their research to reveal the deepest secrets of the cosmos. This series will look at the strangest, coolest, most exciting facts that we have discovered in hundreds of years of modern science. Fact #3: The Universe is made of a ridiculous amount of nothing. What is everything made of? The answer will change depending on how much education you have. For most of...
With the historic fly-by of Pluto last month, NASA’s New Horizons spacecraft gave us an up-close look at the former 9th planet, showing that it is a dynamic world with icy plains, tall mountains, and an atmosphere. But now that New Horizons has passed by Pluto, it has the infinite cosmic horizon in its stead. So what’s next for the $700 Million spacecraft? Its battery will keep it going for a few more decades, and it will likely pass beyond the edge of the solar system, in the stead of the Voyager crafts. What else is ahead? The good news is...
I am always fascinated by the diversity of colours, shapes, and scenarios that pop up throughout our universe. Even though we can classify things into categories like ‘planetary nebula,’ ‘galaxy,’ ‘dwarf star,’ and such, there is still a huge amount of variability among these categories. The most diverse group may be nebulae, since their shape relies on what elements are present, the environment in which they formed, and how far along they are in their evolution. A great example of a strange and interesting nebula is the PN M2-9, the Twin Jet Nebula. Lying 5,560 light years away, in the...
We know that solar systems form in a disk shape, with the star forming in the middle and any other rocks, presumably planets, form out from the center in whatever dust and gas remains. But what about the space between stars? Is it truly empty? And if there is something out there, how could we find it? How did it get there? For years, astronomers and chemists (believe it or not) have been trying to answer these questions and more. The specific problem is that when we take a spectrum of a distant star, we see a collection of 400...
I was doing my daily check of some astronomy and space news sites to see what was happening today, as I do every morning before I decide what to write about in my daily blog post. I looked at today’s astronomy picture of the day, a gorgeous work of astrophtographic art showing Mt.Rainier and dozens of meteors, all in front of the sharp filaments of gas of the Milky Way. As a newbie in the world of astrophotography, I look at this picture and try to think about how it was done. Did he take a foreground shot to get...

This series will look at the strangest, coolest, most exciting facts that we have discovered in hundreds of years of modern science. Fact #2: There are more Galaxies than you could possibly count. Our night sky is jam-packed with stars. If you’ve ever left the city to go far beyond the reach of...
Type 1a supernova explosions are used by Astronomers as a standard candle for measuring distances in Astronomy. They all explode with the same intrinsic brightness, and so depending on their apparent magnitude, ie how bright they look, we can determine the distance to them. It’s like a 40 watt light bulb. No matter how far away I move it, it’s still 40 watts, even though it looks dimmer if it’s further away. However, a few months ago some research came forward about type 1a supernova explosions, hinting that there may actually be two or more distinct types with slightly different...
An unusual Phenomenon known as a Red Sprite has been seen by the International Space Station as it orbits the Earth. Seen above a lightning storm, it is unknown what causes this rare phenomena of tendril-like lines that extend up into the atmosphere from the lower storm. The Moon is visible near the centre of the frame, and to its right we can see the constellation of Orion above the atmosphere and lights of our comfortable planet Earth. Along the horizon at the right side of the image is the visible red sprite, occurring quickly during this longer exposure. Amazing...

This series will look at the strangest, coolest, most exciting facts that we have discovered in hundreds of years of modern science. Fact #1: The Universe is Far Larger than you Can Possibly Imagine Let’s start with the fastest speed ever travelled by a human being, about 11 Km/s (40,000 Km/h). This is incredibly fast...
The next mission to Mars, called InSight (Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport), is slated to launch in Spring of 2016. It will be the first stationary lander to investigate the internal structure of Mars and search for seismic activity, ie marsquakes! NASA has always been good at including space enthusiasts in the public in their missions, giving them a human feel, and this mission is no exception. You can sign up to have your name included on a silicon microchip on the lander! In the first 24 hours, NASA has had 67,000 people sign up, and they expect...
