ALT The background is mostly dark. At the center is a dark orange-brown circle, surrounded by several blazing bright, thick, horizontal whiteish rings. This is Saturn and its rings. There are three tiny dots in the image—one to the upper left of the planet, one to the direct left of the planet, and the lower left of the planet. These are three of Saturn’s moons: Dione, Enceladus, and Tethys, respectively. There is a slightly darker tint at the northern and southern poles of the planet. The rings surrounding Saturn are mostly broad, with a few singular narrow gaps between the broader rings. There is an innermost, thicker ring, and next to that is a brighter, wider ring. Traveling farther outward, there is a small dark gap before another thicker ring. In the thicker ring, there is a narrow faint band. There is then an outermost, faintest, thinnest ring.

ALT The periodic table organizes all the known elements by atomic number, which is the number of protons in each atom of the element. This version of the table, which draws on data compiled by astronomer Jennifer Johnson from Ohio State University, shows our current understanding of how each element found on Earth was originally produced. Most of them ultimately have cosmic origins. Some elements were created with the birth of the universe, while others were made during the lives or deaths of stars. The Nancy Grace Roman Space Telescope will help us understand the cosmic era when stars first began forming. The mission will help scientists learn more about how elements were created and distributed throughout galaxies.
