What do galaxies really look like




















For the photo of Uranus, he used data collected by Voyager 2. The spacecraft only had enough time to capture half the rings in high resolution, so Benson cloned the rest in Photoshop. The process took four days, not including the extra hours he spent tweaking color and contrast to get the final image just right. What you see in the end is a photo as close to Uranus as the data allows.

Benson hopes the images convey a sense of wonder, and shows the role artists can play within a field typically dominated by scientists and astronomers. Contributor Instagram.

We believe that now, more than ever, the world needs people who care about science. Help us fund the future and next generation of problem solvers, wonder seekers, world changers and nerds. Even if they use red, blue, and green filters of visible light, often they'll assign those colors to highlight things like oxygen, hydrogen or whatever they're studying in the image.

Well, we can get pretty close to true-color images if the goal is to create a visually accurate depiction. The light that we see from each of these galaxies comes from the stars inside it. Sometimes galaxies get too close and smash into each other.

Our Milky Way galaxy will someday bump into Andromeda, our closest galactic neighbor. But even if it happened tomorrow, you might not notice. What Is a Galaxy? The Short Answer:. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. More on Galaxies!
