Looking Closer and Testing Theories

Last week, while looking at some of the best images from the Cassini spacecraft, I commented on the fact that the smooth rings of Saturn are small, varied chunks of ice and rock when you get down to the smaller scales.  Reflecting on that this morning, I was thinking about how observing objects in our universe at smaller scales gives new insight into the variety and complexity of natural phenomena.  Not long after, I came across a story of a new interesting object in our own Solar System. A new binary asteroid was discovered.  This in itself isn’t too different...

Latest Weather Update from Pluto: Hazy with a chance of Ice Flows

Friday’s science update from the New Horizons team shed some more light on the seemingly endless jaw-dropping discoveries from the Pluto system.  We have found a surprising atmosphere and very cold ice flows, contributing to a surprisingly active geology for an object that receives so little sunlight.  Seven hours after the craft made its closest approach of Pluto, it turned around and took a backlit shot, revealing two distinct layers of hazy atmosphere at 80 Km and 50 Km above the surface respectively. It looks more like an eclipse photograph from much closer to home, but it shows a hauntingly...

Mars keeps on Surprising: It has Glaciers!

As the inevitable launch of humans to Mars slowly approaches over the coming decades, we are using our best technology to study our neighbour in detail.  With multiple orbiting satellites and ground surveyors, we are slowly learning more about the geology, climate, environment, and history of Mars.  It feels as if every new discovery is a surprise, and we never expected Mars to be such a dynamic and complex world.  With science and technology improving every year, humanity is focussing efforts on the red planet.  The latest incredible discovery comes from radar data from the Mars Reconnaissance Orbiter (MRO).
