I was very excited to read about the discovery published last week by NASA’s Curiosity rover of the seasonal variation in the amount of methane in Mars’ atmosphere. Curiosity found that the average methane concentration varied from 0.24 parts per billion (ppb) in the northern hemisphere winter to around 0.65 ppb in the summer. This… Continue reading Methane on Mars
Ever since the pioneering work of Frank Drake (1930-) in 1960, astronomers have been looking for radio signals from extraterrestrial civilisations and have failed to find anything. This could be because Earth-like planets containing complex life forms (such as ourselves) are rare in the Universe and only a series of highly improbable events led to the… Continue reading The Rare Earth hypothesis

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
This post is about the zoo hypothesis, a term coined in 1973 by the astronomer John Ball, but the idea had been in existence for decades before then. The zoo hypothesis states that there are many advanced and intelligent alien civilisations out there, but they hide their existence from us so that they they do not interfere with our… Continue reading The zoo hypothesis
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?
