Why is Mercury so Dark?

Mercury, the smallest planet in the solar system, and closest to the Sun, is only a little bit bigger than Earth’s Moon.  But the Moon is comparatively reflective object.  Mercury is thought to be made of the same rock as the Moon, so what is the difference? Why do objects in our Solar system have […]

Huge Physics News: Neutron-Proton Mass Difference Found!

Our entire universe, from the tiniest atoms, to the structure of our experiential world, to the most massive galaxy clusters and the cosmic web, is dependent on a set of single properties, where small changes to these fundamental numbers would lead to a state where none of it could exist.  Understanding these fundamental numbers is […]

One Year Mission on the ISS Begins!

When Canadian Astronaut Chris Hadfield was in space, on the International Space Station (ISS), he stayed there for six months, the standard length of stay for an astronaut.  On the ISS, three of the six-person crew are replaced every three months.  After returning to Earth, Hadfield could barely walk.  He had lost bone density and […]

Dark Matter is Darker than we Thought?

We call it dark matter because it doesn’t give off light, right? Well there is a lot of matter than doesn’t radiate, but the difference is that whatever the stuff is that we call dark matter doesn’t interact with anything through the small-scale fundamental forces.  The only way we have been able to detect it’s […]

Best View Yet of Gas Cloud Passing Milky Way Black Hole

A few months ago I talked about Astronomers seeing the gas cloud known as G2 passing the central black hole of the Milky Way, called Sagittarius A*, and how we had hoped to watch the black hole destroy it in order to learn about the behaviour of supermassive black holes.  As we all sat and […]

Measuring Saturn’s Speedy Rotation

How do we measure the rotation speed of a planet? Exactly as you would expect.  Watch the surface, look for markable features, and time how long it takes until those features pass the same point again in the future.  But how can we possibly nail down this information when the planet has little to no […]

Jupiter Came in Like a Wrecking Ball! A New History of Our Home System

It’s difficult to determine the history of the Solar System.  The planets have been in their current orbits for Billions of years, and any signs of prior activity or configuration has to come from leftover geologies of smaller, rocky worlds.  It makes it especially difficult when the Billions of interloper asteroids and comets throughout history […]

Biggest Asteroid Impact Crater Ever Discovered in Australia

We have found evidence of ancient impacts all across the Earth, from the famous Chixulub crater in Mexico to the Sudbury Basin a little bit closer to my home.  From Space the remains look nothing like craters, millions of years of sediment and growth hide the massive regions from obvious detection, but signs remain of […]

One Night with Mars, One with Venus – The Moving Moon

Yesterday I posted some of my own photos of the Moon and Mars in conjunction from the night before.  Last night I went out again knowing that there was another planetary conjunction in the works.  The Moon was now with Venus.  People on the internet and in person were asking me “Mars? I thought the […]
