How does the Hubble Space Telescope take long exposure photos if it is constantly orbiting the Earth?
I have a question about the Hubble Space Telescope. I know it takes long exposure photos of space, but how does it do that if it's constantly orbiting the Earth? Wouldn't the motion blur the images?
That's an interesting question. The Hubble Space Telescope uses a technique called "guiding" to counteract the motion of the spacecraft. The telescope locks onto a guide star and adjusts its own motion to keep the guide star in the same place in the field of view. This allows the telescope to take longer exposures without motion blur.
