Plasmas have the potential to be used in various ways, including healing wounds, making computer chips and cleaning the environment. In cooperation with NASA, JAXA will look at the strength of light at different wavelengths, the temperature of things in space and their shapes and brightness.ĭavid Alexander, director of the Rice Space Institute at Rice University, believes the mission is significant for delivering insight into the properties of hot plasma, or the superheated matter that makes up much of the universe. Instead, astrophysicists use special detectors to observe gamma rays and to figure out where they come from in the sky.An HII-A rocket blasts off from the launch pad at Tanegashima Space Center in Kagoshima, southern Japan Thursday, Sept. They go straight through optics used for other wavelengths, making them impossible to reflect or refract. Gamma rays are the universe’s most energetic form of light. Engineers at NASA’s Goddard and Marshall Space Flight Centers have designed mirrors like these for missions like the X-ray Imaging and Spectroscopy Mission (XRISM) and the Imaging X-ray Polarimetry Explorer (IXPE). Since there’s a lot of empty space in the middle of a single paraboloid, X-ray mirrors incorporate multiple mirrors as nested onion-like shells. This is called a grazing incidence mirror. To detect them, engineers turn the mirrors on their sides so the X-rays can skip off the surface. ![]() X-rays can simply pass through the atoms that make up most telescope mirrors.

X-ray mirrors use the slightly angled side of the paraboloid. ![]() The Webb mirror, for example, is coated with a thin layer of gold so that it can reflect infrared light. Telescope mirrors are coated with different materials depending on the color of the light they need to reflect. (Backyard telescopes can also have mirrors, too.)Īn X-ray Mirror Assembly built for the X-ray Imaging and Spectroscopy Mission consists of a primary and secondary mirror, each containing 812 nested foil mirror segments. Large mirrors can be made thinner and lighter than lenses of the same size, which makes reflecting scopes ideal for sending to space. ![]() Reflecting telescopesĪ telescope that uses a mirror as its primary optical element is called a reflecting telescope. The first telescopes, developed in the 1600s, were refractors, as are many backyard telescopes today.īut very large lenses make refracting telescopes large and heavy, which makes them difficult to use in space. Like eyeglasses, the lenses bend, or refract, light passing through them. Refracting telescopesĪ telescope using a lens for its main optical element is called a refracting telescope. The larger a mirror or lens, the more light it collects, and the better its ability to detect fainter objects. A dramatic structure of arched, ragged filaments. At the centre of the region is a brilliant star cluster called NGC 346. The size of the main mirror or lens determines how well a telescope can collect light. This Hubble Space Telescope view shows one of the most dynamic and intricately detailed star-forming regions in space, located 210,000 light-years away in the Small Magellanic Cloud (SMC), a satellite galaxy of our Milky Way. Astronomers observe distant cosmic objects using telescopes that employ mirrors and lenses to gather and focus light. ![]()
