"Is Anyone Out There?" is about the likelihood of there being extraterrestrial intelligent life. It is based on a number of posts from my blog.

Voyager 40th anniversary
Nearly 40 years ago, on 20 August 1977, the Voyager 2 space probe was launched from Cape Canaveral, Florida, on a mission to study the Solar System's four outermost planets. It was followed 15 days later by the launch of an identical spacecraft, Voyager 1. The Voyager spacecraft -Image from NASA Although Voyager 1 was… Continue reading Voyager 40th anniversary

Life in our galaxy?
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?
Enceladus -Could there be life?

The Science Geek
Welcome
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!
