A cutaway depicts the interior of Neptune (left). In the new experiment, Kraus et al studied a plastic simulating compounds formed from methane -- a molecule with just one carbon bound to four hydrogen atoms that causes the distinct blue cast of Neptune; methane forms hydrocarbon (hydrogen and carbon) chains that respond to high pressure and temperature to form ‘diamond rain’ in the interiors of ice giants like Neptune; the authors were able to recreate similar conditions using high-powered optical lasers and watch the small diamonds form in real time with X-rays.

The six most common elements of life on Earth (including more than 97% of the mass of a human body) are carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus. The colors in the spectra show dips, the size of which reveal the amount of these elements in the atmosphere of a star. The human body on the left uses the same color coding to evoke the important role these elements play in different parts of our bodies, from oxygen in our lungs to phosphorous in our bones (although in reality all elements are found all across the body). In the background is an artist’s impression of the Galaxy, with cyan dots to show the APOGEE measurements of the oxygen abundance in different stars; brighter dots indicate higher oxygen abundance.
