Universe Puzzle No. 5

As with last week’s Universe Puzzle, something that cannot be answered by five minutes spent googling, a puzzle that requires you to cudgel your brains a bit, and do some lateral thinking. This is a puzzle on a “Universal” topic – astronomy and astronomers; space, satellites, missions, and astronauts; planets, moons, telescopes, and so on.

What do the following have in common?

UPDATE: Answer has been posted below.

Alice, Hanny, Kate, Pamela

They are all featured in Galaxy Zoo’s She’s an Astronomer: Alice Sheppard, Hanny van Arkel (of the Hanny’s Voorwerp fame), Kate Land, and Pamela L. Gay (of Astronomy Cast fame!)
