Over the course of the past year, in countless news articles, we’ve become intimately familiar with the look of a certain blobby sphere with spikes sticking out of it. Just as advancements in telescope and detector technology have uncovered more and more secrets of the universe, concurrent advancements in microscopy, diagnostic medical imaging, and even particle physics have similarly uncovered a rich and dynamic world that we are completely oblivious to, yet exists all around and within each of us. I would simply like to point out that we often take for granted a fantastical realm that exists right in front of our faces at all times. Why are these fantastical landscapes that Hubble reveals actually real, and what does that mean? What does Hubble reveal to us about the nature and limitations of human vision? Why do we tend to become preoccupied with asking the question “Is that what it would look like if I could go there in a spaceship and see it with my eyes”? But, before we dive into those deep questions of the macrocosm, let us first consider something a little closer to home, the microcosm! Macro to Micro ![]() Now, I would like to take a step back and consider what Hubble reveals to us about the universe. We’ve also explored the history of astrophotography placing Hubble within the larger historical context of astronomical imagery-demonstrating a clear path to Hubble through the advancements of both the process of photography and the development of more sophisticated telescopes. ![]() This allowed us to explore the different kinds of image artifacts that image processors deal with when processing data from Hubble. So far in this series of posts, we’ve taken a close look at Hubble’s optical system, and the path of light through the telescope into its detectors. In this post, we’ll look at a few examples of how Hubble extends beyond human vision to illuminate our understanding of the universe. This series of posts is dedicated to the scrutiny of Hubble imagery and a broader discussion of the veracity of astronomical imagery.
