Why the night sky is dark?
Roger Barlow, University of Huddersfield Why the night sky is dark? It sounds obvious. That’s what night is. The sun has set and when you look up at the sky, it’s black. Except where there’s a star, of course. The stars are bright and shiny.
This is why light pollution in cities is a very bad thing
Do you remember when did you see a sky full of stars last? It’s been many years for me, I even can’t remember when I saw last. A lot of young people didn’t see even once, because of the light pollution in cities, since they were born in cities and probably never went to the […]
Five Moon myths – and how to disprove them yourself
Daniel Brown, Nottingham Trent University This year’s first supermoon will potentially grace the sky on February 9. A supermoon is usually defined as the largest full moon possible.

Proxima Centauri c: how we spotted a potential new planet around the Sun’s neighbouring star
Hugh Jones, University of Hertfordshire Most exoplanets, bodies orbiting stars other than the sun, are too far away for us to be able to send probes to. So it’s no wonder that the discovery of a possible habitable planet around the sun’s nearest neighbour star, Proxima Centauri, a few years ago generated a lot of […]
