X-ray Space Telescope
Located in orbit around our planet at 139,000 km above the surface, Chandra helps us discover more about our solar system, our galaxy, and our universe. It takes pictures in the electromagnetic spectrum of x-rays. This helps us look farther than just visible light and see a new perspective of our galaxy in a new way. It is located in space because the Earth's atmosphere blocks out the radio waves from outer space so therefore it has to be outside of it to pick up the waves.
Measuring 45 feet long, Chandra is slightly longer than an average school bus, it's largest lens is 1.2 meters in diameter. It operates by having 4 mirrors of changing size fit into each other to accomplish the focus that allows it to take such astounding images.
When taking pictures of distant stars we would sometimes notice that the images would be fuzzy and swirled, with a large nothingness in the center. We later discovered that these nothingness were in fact black holes that distorted the light what was passing from those stars to our telescopes. After launching Chandra we were able to take pictures of these black holes and see that the images had a center of black with a swirling mass of super heated mass and gas that orbited the supposed black holes. Chandra has also helped us try and validate the theory on Dark Matter.
When a star is near the end of its life cycle, it has the chance of becoming a super nova. When he sun implodes and then explodes spreading its dust and mineral particles out into deep space it also releases huge amounts of X-rays. Chandra helps us see these radio waves and locate where a sun went super nova.
