It has been 15 years since November 2nd, 2000, when Astronauts first occupied the International Space Station. Since then, it has been inhabited continuously by a team of up to six people. 220 citizens of Earth from 17 nations have flown with $100 Billion station over many 45 minute orbits of our planet. The men and women who have spent time aboard the station have had a view of our world that so many people have never experienced. Seeing the planet as a planet, one of countless other worlds in a dark empty void dotted by stars, it changes your perspective on...
Halloween is an amazing chance for people to be someone (or something) they have always wanted to be. To step outside of their norm and live their life as an alter ego, if only for one night. This is why so many people have crazy Halloween stories, and why the ‘holiday’ captivates us so much. With humanity’s excellent pattern recognition skills, we tend to see spooky things in space, where if you would just turn the picture 90 degrees, it probably would look like some other item from human experience, and not be spooky after all. Here are a few...
It always fascinates me to see videos and photographs from the International Space Station (ISS), how simple day to day activities are so altered because of the altered Physics of constant free fall in orbit around the Earth. Many of the videos are showing what people call the ‘effects of zero gravity.’ This is actually not the case. There is gravity in space. Let’s take a closer look at the situation of an ISS astronaut. If we do the math (I do realize the term ‘do the math’ turns away a lot of people, so I will keep it short),...
The Sun. A bright fiery light in the sky to some, worshipped as a god by others, seen as a massive ball of hydrogen plasma 150 million kilometres away by scientists. Once in a while, the Sun goes ahead and releases massive amounts of charged plasma particles toward the Earth. The particles should eradicate humanity with horrible burns and render our planet lifeless, but luckily… they don’t. Why? The Earth’s magnetic field protects us, funnelling the particles to the poles where they ionize gases in the atmosphere and become harmless. The bonus for humanity, aside from not dying, is that we...
Did you know that more than two-thirds of stars are part of multiple systems, where two or more stars orbit a common center of Gravity? This means that the Sun is one of the minority, being on its own. Most of the multiple systems out there are in fact double star systems, but some of them are triples and a few are quadruples. One such quadruple star system, known as DI Cha (in the chameleon constellation), was recently imaged by Hubble. The system lies in the southern constellation of Chameleon, about 520 light years away. The quadruple system is a...
Today is the day that one year ago that I sat down and decided I wanted to improve my writing skills. I decided I wanted to keep up with the latest news in the world of astronomy and space science. I decided I wanted to learn astrophotography and renew my passion for astronomy, a passion I have had since I was 6 years old. I decided I would write an article every day, or at least post something. And even though I didn’t write a post every 24 hours, due to vacations, family events, and life getting in the way,...
The Earth, along with the rest of the solar system, was born around 4.6 Billion years ago. At that time, Earth was part of the early group of habitable planets to form in the Universe. According to a new theoretical study from the Space Telescope Science Institute (STScI), the vast majority of Earth-like planets has yet to form. Using data from the Hubble space Telescope (HST) and the Kepler Space Telescope (KST), astronomers were able to come up with a theoretical model of cosmic evolution, detailing how planets will form over the entire lifespan of the Universe. “Our main motivation was...
This past week, American astronaut Scott Kelly, currently on a one year stint aboard the International Space Station, broke the record of 363 days for most time logged in Space by an American. Kelly will continue to run up the tally, as he is just over halfway through his one year mission. His record comes from a total of four space missions, including two Shuttle missions and two ISS stays. While Kelly continues his mission to determine the long term effects of space flight on humans, his fellow ISS astronaut Andreas Mogensen has been testing a new skin suit developed...
Every so often we see a new set of images from Pluto, giving us a chance to rediscover it multiple times. It’s like we are experiencing the July fly-by over and over again, and each new set of images reveals something new and exciting. I feel the same sense of excitement and discovery each time I see a new image, realizing that it spent 6 hours as a beam of light crossing the 5 Billion Kilometres of the solar system to connect us to the New Horizons probe, a lonely little piece of human ingenuity flying through the darkness. Here...
Is this a giant hole in space? I show a picture similar to this as I ask this question to students and audiences that I host in my planetarium. Most people answer that it is a black hole, or dark matter, or dark energy, or something strange like that. But the amazing thing is that it is actually a thick cloud of dust that is opaque, letting no visible light from the distant stars pass through. The funny thing is that the cloud is transparent in infrared light, but in the visible spectrum it highlights something interesting about the universe:...
