Review: IMAX: A Beautiful Planet

I recently had the opportunity to watch a brand new IMAX feature, called A Beautiful Planet.  It features incredible views of the Earth from space, captured by astronauts aboard the International Space Station.  Most of the footage was taken during Expedition 42 on the ISS, starting with the arrival of Samantha Cristoforetti, Terry Virts, and Anton Shkaplerov aboard the […]

Mercury Transit Now!

The Transit of Mercury is happening right now here on May 9th, 2016.  If you want to watch live, check out the NASA feeds from the Solar Dynamics Observatory. For the small size of Mercury, it makes a pretty stark contrast against the bright Sun, and is easy to see, even in a small telescope.  […]

Rockets Blowing Up

Modern rocketry is a pinnacle of engineering.  It requires the right balance of multiple systems, and a deep knowledge of scientific principles such as fluid dynamics, aerodynamics, and chemistry.  But a huge part of the brute force science done in rocketry has been ‘try and fail.’  Countless rockets have exploded in tests dating back to […]

The How and Why of Planet Nine

It hasn’t been found yet – let me make that clear.  But with evidence that it should exist, astronomers are looking more closely at the proposed planet nine and how it might have formed, and how it could have ended up in such a distant orbit. When you start to think about how a planet ten times the […]

Martian Water is Quick-Boil

At this stage of our understanding of the planet Mars, we have seen salty water flowing (recurring slope lineae), found evidence of ancient riverbeds, and seen seasonal changes in the polar caps.  But an important question is how does water behave on Mars? A bit of science here on Earth gives some insight. Water at sea […]

Mercurian Monday

If you haven’t already heard, Mercury is going to transit the Sun this coming Monday! It’s like a solar eclipse, except Mercury is covering the Sun instead of the Moon.  And since Mercury is tiny and far away, it’s not so much ‘covering’ the Sun as it is passing across the face of the Sun […]

Three Nearby Earths

As the search for planets in the galaxy continues, there are two places to focus on: Distant stars with potential large planets, and nearby stars with potential small planets. If we are able to find Earth-like planets orbiting nearby stars, they will be prime targets for future generations to explore. Astronomers have just announced the discovery of […]
