One of the most fascinating things happens whenever I show someone the planet Mercury in the sky. Their first reaction is to be surprised at how bright it is. Most people think of Mercury as a faraway planet, too close to the Sun to see at all. But in reality, Mercury is close to Earth, and when the angles are just right, it’s not hard to find. Mercury is 57 million kilometers from the Sun, more than a third of the way to Earth. We are also much closer to Mercury than we are to Jupiter and Saturn. When we see the...
Since the dawn of human history, we have looked up into the night sky and found patterns in the stars. Some of us saw animals, others saw gods and heroes, but we all agreed that they were greater than our simple existence. In this blog series, we will take a deeper look into the constellations that Astronomers use to map today’s night sky. We will look into the history of each of the 88 constellations and the stars and objects that form them, to discover more about our culture, and our connection with the universe. Our first constellation on the list is bright, large,...
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...
At least once a month we hear of a new exoplanet with a strange and amazing story. From the ‘Super-Saturn’ ringed world to Magnetic Fields to systems of three Earths, there is an abundance of planets and strange systems. The latest weird discovery brings us to a star 1,500 light years away in the constellation Cygnus. The small-Mercury sized planet it hosts orbits in only 16 hours, bringing its surface temperature to over 1,800 degrees celsius. This amount of heat is enough to vapourize rock, and so the star is literally roasting the planet and blasting away its surface. The dust...
NASA is sure to start selling trips to these fabulous space destinations! The only problem is that we have no way of getting there, or more importantly, back home. Still the posters give a great homage to the ‘see America’ posters of the 1920s, and they sure make me want to visit. Kepler 186f is a habitable zone planet around a red dwarf star, meaning it could support liquid water. If any plant life forms on this planet, it would photosynthesize differently, potentially giving it a red colour palette. HD 403007g is a planet with 8 times the mass of Earth....
