Dr. Easton’s specialty is using advanced imaging technologies to recover long lost texts from ancient manuscripts which are faded or used recycled parchment. One example of such recovered documents is by Greek astronomer Hipparchus. (c. 190 – c. 120 BCE) who created the earliest known star chart  but this had been long lost. In 2017, part of it was found when a medieval manuscript was analyzed to recover the text that had been lost when scraped clean to reuse the parchment pages.

Dr. Kartaltepe is an astrophysicist expert in galaxy formation and evolution. She currently studies the oldest galaxies yet found by the James Webb Space Telescope. Her study with peers published this past August confirmed that the very distant Maisie’s Galaxy existed when the 13.8 billion-year-old universe was just around 390 million years old, which is incredibly young for our cosmic expanse. This makes it one of the four earliest galaxies ever seen by human eyes.
