In a major announcement this week, researchers with the Kepler Space Telescope science team have confirmed the existence of 1,284 new planets that had originally been found by Kepler. This is a huge leap in the number of confirmed planets, bringing the total to over 2,300. The previous science data collection done by Kepler was completed in 2013, so why is this new news? Well the exciting part is that these are confirmed planets. Usually when Kepler detects a signal indicating a potential planet, it needs to be verified by using some of the larger ground-based telescopes. Kepler is not immune...
Everyone in Canada looks forward to the Perseid meteor shower each August. The weather is warm, the skies are clear, and they have a high zenithal hourly rate (ZHR). But once they are done, it’s not long before the weather starts to cool down, Canada moves into Autumn and eventually the deep freeze of winter sends our fine nation into hibernation. But if you do feel like coming out of your fort this weekend, in an unseasonably warm December, you will be treated to what has often been the best meteor shower of the year: The Geminids. Under ideal conditions,...
What do other planetary systems look like? We have seen some where massive Jupiter-sized worlds orbit closer to their star than Mercury does to the Sun, baking them with radiation. Others have had multiple rocky planets within the Earth’s orbit distance. Some have planets similar to Earth in a variety of locations. But what about far away from the star? We never expected to find gas giants like Uranus and Neptune in the far reaches of our solar system. Are there planetary systems where planets live even farther away? Maybe there are planets that live in the empty darkness between stars,...
Today is a busy day in the world of astronomy and space news. The US Air Force has approved SpaceX for military launches, ending a ten year monopoly by Boeing and Lockheed-Martin. A black hole jet moving at nearly the speed of light is having traffic issues, resulting in knots of jet material rear-ending each other. An experiment in Quantum Mechanics has shown that reality simply doesn’t exist until we measure it. Finally, the Gemini planet imager has found a bright, disk-shaped ring of dust around the star HD 115600, which is being likened to the Kuiper Belt in the...
When we have the best telescopes at our disposal, we can take the most detailed data, and ultimately gain the most valuable science. Being able to take a closer look, to resolve the finer details, to see what lies within, gives us the ability to understand the present, peer into the past, and ultimately, predict the future. The ESO’s Very Large Telescope continuously brings in fantastic images of objects that we have studied previously, but weren’t quite sure about. This week we saw another prime example of this. The Medusa Nebula is a planetary nebula in the constellation Gemini. It...
