Last month our Astro Chat with contributor Dr. Jean Creighton began a short series on the impact NASA's Hubble Space Telescope has had on our understanding of the universe.
Previously, we talked about how the Hubble confirmed for us that the universe is expanding. This month, it's all about exoplanets. As Creighton points out, "the Hubble Space Telescope was not the first instrument that saw exoplanets. But it was one of the first that could photograph an exoplanet."
