It’s #International Astronomy Day and Hubble has turned 27 this month! Let’s celebrate with some of its most breathtaking pictures!
An international team of astronomers has made a great discovery. A nearby exoplanetary system has seven earth-size planets!
This documentary explores the tumultuous lives of galaxies with a focus on galaxy collision: the key mechanism in galaxy evolution. Using publicly available images and bespoke animations, we look at how humans began exploring what lies beyond the Milky Way, how the Universe came to
A cool thing to do if you have leftover dry ice is to snuff out candles using just carbon dioxide. You put dry ice in a jar and let it sublimate. The carbon dioxide will remain in the jug, as the density of CO2 is
Thermodynamics is a funny area of physics, where different physical quantities are profoundly connected. In this video we look at how reducing the pressure allows you to reduce the boiling point of water.
In this vlog, I talk about Prof. Payne-Gaposchkin, one the most important astronomers of the 20th Century. Thanks to her we know that stars are not made by the same elements as the Earth, and that Hydrogen is the most abundant element in the Universe.

Since the 25th of March is the anniversary of its destruction and the fall of Sauron I thought I’d dedicate this vlog to answering the question as seriously and as accurately as possible.
The final feature for this series is Life. The Universe is such mind-boggling huge place that we are most definitely the best that random chances and selfish genes can produce. NASA defines life as a: “Self-sustaining chemical system capable of Darwinian evolution”. “Self-sustaining” specifies that given
