This image shows the sample chamber inside of a diamond anvil cell, looking axially through the top diamond. The sample originally exists of carbon and sulfur, shown as a black powder, sitting inside a hydrogen-rich environment. The sample is at 4 GPa and is illuminated by 10 mW of 532 nm of laser light to initiate and take to completion the photochemical reaction to produce a Van der Waals solid.

An artist’s impression of a thermonuclear supernova: the material ejected by the supernova will initially expand very rapidly, but then gradually slow down, forming an intricate giant bubble of hot glowing gas; eventually, the charred remains of the white dwarf that exploded will overtake these gaseous layers, and speed out onto its journey across our Milky Way Galaxy.
