The 2019 Nobel Prize in Physics was awarded to with one half to James Peebles “for theoretical discoveries in physical cosmology”, and the other half jointly to Michel Mayor and Didier Queloz “for the discovery of an exoplanet orbiting a solar-type star.” This graphic takes a look at the prize-winning research.

This year’s second Nobel Prize in the sciences was awarded today. The prize for physics was awarded to researchers who contributed to the observation of gravitational waves, ripples in space-time that were originally created by colliding black holes over a billion years ago.
It’s one of the most popular science demonstrations: Pop a handful of Mentos candies into a bottle of Coke, and a fountain of bubbles rapidly spurts from the open bottle, often over a metre into the air. Originally the explanation for the effect was thought to be quite simple. However, scientists are finding that there’s more to this spectacular demonstration than meets the eye.
Today, 30 August, marks the birthday of Ernest Rutherford. Rutherford is primarily considered a physicist, but his contribution to our understanding of the atom is also important to chemistry. He was also a chemistry Nobel Prize winner, for his work on radioactivity. This graphic looks in detail at one of his most famous experiments, the gold foil experiment which is often name-dropped in school science lessons!
