A ‘Van Gogh View’ Of The Polaris Flare

Space images can often be breathtaking and the night sky has often inspired artists to produce incredible masterpieces. Sometimes even the way astronomers represent data can be both scientifically and artistically stunning. Case in point is the polarization map released by the Planck Collaboration, which

A Ghostly Cradle Of Stars

If you wonder where we came from and how we got here, there’s a step we are quite confident on. About 5 billions of years ago, before the Sun shone a single ray all the atoms you are made of were part of a large

More On Gravitational Waves

In a previous post, we discussed the groundbreaking discovery of gravitational waves and it’s importance for science as a whole. Now LIGO has observed another detection, and it has the incredible feature of being the first direct observation of a spinning black hole. The merging

What Would Being In Space Without A Suit Be Like?

Spacesuits are a fundamental tool for keeping astronauts safe in space, but the protection they supply is often mistaken, exaggerated or romanticised in science fiction.   Spacesuits are garments worn by astronauts to survive the harsh conditions of outer space.  They should be thought of
