Astronomy Picture of the Day
Summary: A periodic table infographic detailing the astrophysical and human-made origins of all known chemical elements.
This educational graphic, produced by NASA's Goddard Space Flight Center, presents the periodic table of elements with a unique color-coded system. Each element is marked with an icon representing its primary source in the universe, including the Big Bang, dying low-mass stars, dying high-mass stars, white dwarf supernovae, merging neutron stars, cosmic ray collisions, radioactive decay, and human-made synthesis. The chart provides a visual guide to nucleosynthesis and the cosmic history of matter.
