Black Hole Safety Coloring Pages
Have you ever thought about visiting a black hole? We sure hope not. However, if you're absolutely convinced that a black hole is your ideal vacation spot, watch this video before you blast off to learn more about them and (more importantly) how to stay safe. Then, color your own scenes from the video!
What do all scientists have in common? No, it is not that they wear pocket protectors or are geeks. It is that they all ask questions. Lots and lots of questions, since asking questions about what you see is one way to figure out how things work. Here at NASA's Goddard Space Flight Center, there are lots of people working towards a better understanding of the Universe around us. However, it is not always clear how particular observations can shed light on how our Universe works. Have you ever wondered how scientists work to understand the things in the skies around us? Have you ever wondered what the rocket scientists at NASA DO at work all day? Or how they spend their weekend?
Many times, the best way to learn about something is to do it. We think the best way to learn about what an astrophysicist does would be to spend a day (or two or three) in the shoes of one. But since we don't have room for everyone who visits our web site to visit our lab, we've tried to do the next best thing. In these web pages, you will be given a real problem in astronomy which you solve by traveling through web pages, exploring different options and learning many different things along the way.
This feature will give an impression of how immense our Universe is by employing a method used many times in "Power of 10" films - that is, starting with an image of the Earth and then zooming out towards the furthest visible reaches of our Universe. This is not, however, an exercise in "powers of 10" - on the contrary, our goal is to show you astronomical distances without scientific notation. We instead focus on the large number of zeros that are in astronomical distances when we measure them with a familiar unit like the kilometer. The number of zeros increase with each zoom, though not at a constant rate.
