Description:In a series of 20 letters, a modern astronomer, stymied by the pandemic, brings Galileo up to date on what’s been happening in their beloved science since he left the planet 379 years ago. The letters span the universe of modern space science, astronomy and astrophysics -- from lunar missions to exoplanets, from stellar origins to black holes, from the big bang to dark matter. But it is also a personal story of a 21st century explorer acknowledging his debt to a brave trailblazer. Enlivened by personal stories, artwork, photographs
