Updated November 25 2025 In what is a departure from my usual topics of astronomy and space science, I've written a series of posts on the transition to electric vehicles. This is second in this series. In this post I will discuss the issues of the limited range of EVs and the high costs of… Continue reading Electric Vehicle Range Challenges
The UK is transitioning to electric vehicles (EVs) and will phase out the internal combustion engine (ICE). Challenges remain, including public charging infrastructure and EV battery costs. These posts explore these issues and highlight improvements in ICE emissions, emphasizing the need for a shift to greener transport alternatives.
I started my Explaining Science blog nearly 11 years ago in April 2014. Back then I wasn't sure how long I'd want to keep it going. But now in 2025 I still find that I enjoy blogging very much. In July 2020, the year of the first covid-19 lockdowns in the UK, I started the… Continue reading Creating Videos
When measuring the brightness of objects in the sky, astronomers use the magnitude scale. The basis of the scale we use today was invented by ancient Greek astronomers. They classified all the stars into six magnitudes. The brightest stars were magnitude 1, the next brightest magnitude 2 and so on. The faintest stars visible to… Continue reading The Magnitude Scale
Updated 21 November 2025 In 1.3 million years’ time the star Gliese 710 is forecast to pass within 0.166 light years of the Solar System, 25 times closer than Proxima Centauri which is our current nearest star (excluding the Sun of course). The close approach of Gliese 710 will be the strongest disrupting encounter known… Continue reading Gliese 710: The Closest Future Star Encounter
