With the recent discovery of three planets orbiting the red dwarf star Trappist-1 which have a similar size, mass and average surface temperature as the Earth, there has been considerable speculation as to whether one or more of these planets supports life. What the surface of Trappist 1f, one of the planets orbiting Trappist 1, might look… Continue reading Life in our galaxy?
Three years ago my first ever post was about Saturn’s moon Enceladus. It is interesting that once again this small moon is in the headlines as a possible place on which there could be life.

Hello and welcome to the first post from the Science Geek 01. I intend to write a weekly blog about various topics of interest, which will cover all aspects of science. The articles will be aimed at the non scientist and won’t require any previous detailed knowledge. I hope you enjoy reading them and please feel free to comment.
My first posts will deal with the subject of life within the solar system, which in astronomical terms is our own backyard.
Life on Mars
Throughout most of the twentieth century many scientists thought that there could be life on Mars. Indeed the famous American astronomer Percival Lowell (1855-1916) claimed to have seen through his telescope a large network of canals built by an intelligent civilization and even produced maps of the Martian canal network. These canals certainly provided great material for science fiction writers but they were probably all due to Lowell’s imagination!
Percival Lowell’s Martian…

On 28 October 2015 the space probe Cassini, which has been orbiting Saturn for the last 10 years, will pass within 50 km of the surface of Saturn's moon Enceladus. This is an extremely close approach by an interplanetary spacecraft (by comparison the New Horizons mission only got as close as 12,500 km above the surface of Pluto) and… Continue reading Enceladus Flyby 28 Oct 2015
As a child I was fascinated by the idea of people from Earth encountering alien lifeforms. I was an avid watcher of Star Trek and the British science fiction TV shows Dr Who and Blake's 7. I am not alone in my fascination - the idea of humans making contact with intelligent aliens from other planets has intrigued… Continue reading Is There Anyone Out There ?
Introduction Welcome to the third post from the Science Geek. This post continues my previous two posts and discusses how we might get to Saturn's moon Enceladus, which many scientists now believe is the most likely place in the solar system, other than the Earth, to harbour life. Image from NASA Types of… Continue reading How Would We Get to Enceladus ?
As stated in my previous post NASA's Cassini probe has shown that Saturn's moon Enceladus not only has an thin atmosphere, but that volcanoes of water are erupting from its surface into space. Even more remarkable has been its discovery, that these volcanoes contain the raw chemicals which are the building blocks for life. Image from NASA The question which really… Continue reading Enceladus what kind of life ?
