It’s always funny explaining astronomical time to a non-scientist. I often get the craziest looks when I mention a million years as being a ‘blip on the radar.’ Perhaps there is some immortal alien race out there who would understand how nothing much happens on the scale of the universe in a million years. To humanity and our ever-accelerating advancement, a million years is thrice the age of our entire species. But I guess Einstein was right when he said that ‘it’s all relative.’ This brings us to Saturn, a planet as ancient as the solar system. Moderately old in...
A lot of the data that comes from Space can be called art. Though if you’ve ever seen raw Astronomical data, it’s anything but. It takes a talented artist to bring out the detail in the photo and make it truly beautiful! In the case of large missions like the Cassini Spacecraft, there are a plethora of scientists and artists alike making the most of the data. Especially with Cassini, I always get the feeling it’s a professional photographer taking the photos. The lighting, composition, and other photographic buzzwords are all exceptional, as if it was staged by someone saying...
Since Voyager 1 and 2 passed by Saturn in 1980 and 1981 respectively, scientists have wanted more information about the many amazing icy moons that orbit the gas giant. The follow up mission to Saturn, Cassini, has been in orbit around the planet for over a decade, and has since mapped the icy moons in their entirety. Take a look at some of the Voyager images and how they compare to the new colour maps from Cassini. I should note that the colours in the Cassini images are beyond human vision, extending into infrared and ultraviolet to add some further...
