The Starshade's Veil
A petal of shadow, wide and deep, To watch the rocky worlds that sleep. It masks the glare of a distant sun, So the hunt for life has truly begun. Scanning the dim, the small, the far, Searching for life on a terrestrial star.

Johannes Kepler
Kepler was a German astronomer whose work was fundamental to the development of modern astronomy. He is best known for his three laws of planetary motion, which described how planets move in elliptical orbits around the Sun. His insights broke the long-held belief in perfect circular orbits and laid the groundwork for Isaac Newton's theory of universal gravitation.

The Sum of Two Squares
According to Fermat's Theorem on sums of two squares, an odd prime number can be expressed as the sum of two integer squares if and only if it leaves a remainder of 1 when divided by 4. For example, the prime 13 works because 13 = 2² + 3², and 13 divided by 4 leaves a remainder of 1.
