This illustration shows how the planet HAT-P-2b, left, appears to cause heartbeat-like pulsations in its host star, HAT-P-2.
I am one of the artists that develops education & public outreach multimedia for NASA's Spitzer Space Telescope. Whenever Spitzer data contributes to an exciting new discovery, we look for the best ways to explain it to the general public. Sometimes that means creating a public-friendly diagram from the data. Other times it might mean producing an artist concept that illustrates the discovery. Or a video explaining the scientific process behind it.
