After an epic weekend of eclipse talk, NASA came out with a press conference that overshadowed much more than just the Moon. The announcement, as many had speculated, revealed that conclusive evidence shows there is flowing water on Mars. Like seasons on Earth, warmer conditions cause water to flow down steep hills and into valleys. The speculation came due to the invitation of Lujendra Ojha of the Georgia Institute of Technology to the NASA panel. Ojha noticed strange features on Mars as an undergraduate student in 2010, while looking at images from the Mars Reconnaissance Orbiter (MRO)’s High Resolution Imaging Science...
I promised my friend Dash I would use the term ‘Apoceclipse’ to describe last night’s Perigee Harvest Moon Lunar Eclipse, so here it is! Last night was great fun, even though I couldn’t see the event at all due to cloud cover. Here’s why. It all started with a media blitz and a crazy day at the Science Centre. I started off by doing a Global News interview in the morning, and then a 680 news phone in around lunchtime. I had a planetarium show, and then it was off to CBC downtown to do the national news live! It...
Tonight is the Perigee Lunar Eclipse. A nice video from NASA sums up what we will see, though I still dislike the use of the term “Supermoon.” I’ll be out all night watching it, so stay tuned for pictures! I’m hoping to do a time-lapse of the entire eclipse to make into a movie! It will start around 9pm and peak at 10:47 pm EST. Stay warm!
A few days ago we passed the Autumnal Equinox, and said goodbye to Summer in the northern hemisphere, as the southern hemisphere welcomed Spring. This is all due to the tilt of the Earth’s axis at 23.5 degrees. As it orbits the Earth, the tilt alternately points the hemispheres toward direct sunlight, bringing summer during that time and winter 6 months later. But what about the North and South pole? What happens there? In summertime, because the North pole is actually tilted toward the Sun, the region receives direct sunlight for 6 months! The Sun just never sets! Check out...
One of the things I love most about my job at the Ontario Science Centre is that it gives me opportunities to connect with some pretty amazing people. I’ve met some incredible communicators, scientists, leaders, astronauts, and people from all walks of life doing amazing things. Last night my astronomy background gave me an opportunity to work a special event for future astronauts who are participating in the Virgin Galactic commercial space flight program. The group consisted of about 20 people, some of whom were lead flight engineers and technicians forking on SpaceshipTwo. Others were commercial development and administrators for Virgin...
New science has come forward from a team of astronomers who, earlier this year, discovered a pair of black holes in a close orbit, heading toward a cataclysmic merger. The new results suggest that this incredibly powerful collision will occur much sooner than previously thought, as little as 100,000 years from now (A blip on the radar of astronomical timescales). By precisely calculating the individual and relative masses of the black holes, the team was able to predict how the merger would take place, giving a time line for the collision. The astronomers, from Columbia University, saw bright flashes of light...
I’ve seen images from the Sun in all different wavelengths of light. It looks very different across the electromagnetic spectrum, with some wavelengths making up more of the Sun’s total energy output than others. What’s always striking to me is seeing the images of the Sun that show its structure, including the strange and beautiful features of plasma that dance across it’s surface. A recent APOD captures just such a concept. This image shows the Sun in Hydrogen Alpha, a wavelength of light at 656 nanometres. This is from the ionization of Hydrogen, where the electron is excited and transitions...
This is a story that not many know, about a Russian cosmonaut named Vladimir Komarov. He was one of the first Soviet cosmonauts in the 1960s during the cold war space race between the United States and the Soviet Union. He was the first cosmonaut to fly on more than one space mission, and he sadly became the first human being to die due to space flight. An Aerospace Engineer and test pilot, he was one of the few exceptional candidates accepted into Air Force Group One, the original Soviet cosmonaut program. He wasn’t medically fit for the program on...
A video released a couple of days ago is a brilliant short film about a group of friends who went in to the Nevada desert and built a scale model of the solar system to give us a perspective on how large space actually is. Filmmakers Alex Gorosh and Wylie Overstreet led the project, which featured footage of the production of the model as well as some interesting results. Watch right to the end, where some fabulous footage of the Apollo program is shown, along with some inspiring words from the few men who have seen the Earth from beyond...
I’m over-stimulated. I literally can’t take it anymore. These images from Pluto are mind-blowing, but with so many incredible photos released over the past week, I have reached my limit. I can no longer contain my excitement(not that I have in the past). Here are the newest images showing a Pluto we have never seen before. This second image is my favorite. It shows so much depth and detail, and reveals Pluto to be a world, far more than just a boring rock occupying the outer reaches of our solar system. Visible in the image is the layered atmosphere, mountain...
