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?

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.

Explaining Science (formerly 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!

The Trappist-1 system

I am sure that many of you will be aware of the discovery announced in February this year of seven Earth-sized planets orbiting a small cool star known as Trappist-1. (Gillon et al 2017). In this post I'll talk about this exciting finding and the possibility that some of these planets might support life. Trappist-1 and its… Continue reading The Trappist-1 system

A Christmas present from The Science Geek

  Now that we are into December, Christmas is almost upon us.

"Is Anyone Out There?" is about the likelihood of there being extraterrestrial intelligent life.  It is… Continue reading A Christmas present from The Science Geek

Schiaparelli on Mars -updated

As most of you will already know, and much to our disappointment, the Schiaparelli probe failed to land successfully on Mars last Wednesday. The plan was that when it entered the Martian atmosphere, the spacecraft would immediately begin to slow down to 1700 km/h as a result of the friction caused by the atmosphere hitting its heat-shield.  When it reached… Continue reading Schiaparelli on Mars -updated
