Reflection in a Dark Universe

Like lighthouse beacons in a dark ocean, stars act as tiny islands in the vast universe.  Producing light at the atomic level from the powerful release of energy through fusion, they are the engines that drive the formation of new elements.  But in the darkness there are plenty of other hidden objects that are cold and give off little to no light.  Yet many of them are easily seen.  Here’s Why! The first thing to think about is infrared light, the radiation given off by warm objects.  Large planets and brown dwarf stars are very bright in infrared, much brighter...

Cassini Dives into Enceladus Geysers

Since 2004, the Cassini spacecraft has been orbiting Saturn, giving us unprecedented views of the rings and Moons, and sending back data that has helped us to understand the dynamic nature of the Saturnian system.  The flexibility of such a craft allows for new science goals to be determined in an ongoing basis, since new discoveries often lead to new questions and new areas to focus our resources on.  Yesterday, October 28th, Cassini focused its resources on the geysers of Enceladus, flying lower than ever before over the surface of the icy moon, in an attempt to sample some of...

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). The...
