1 Billion Stars

NASA released a photo of 1 billion stars in the Milky Way courtesy of Gaia. Quite an achievement. It’s the scale that’s staggering. The billion stars is probably far less than 1% of the stars in our own Galaxy. Which is one galaxy of billions in the universe. (One universe of many?). The universe is a big place.
