China successfully launched the Hard X-ray Modulation Telescope (HXMT), an X-ray satellite from the Gobi Desert. The satellite is a telescope that will search the sky for black holes and neutron stars and other energetic phenomena.
The satellite orbits 550 kilometers (342 miles) above our planet. We don’t have to be afraid that the X-rays will penetrate Earth’s atmosphere because they can only be observed by satellites or high altitude balloons.
