Welcome to our Physics lesson on Space Telescope, this is the third lesson of our suite of physics lessons covering the topic of Astronomical Measurements and Observations, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.
Space Telescope
As explained earlier, the technology of artificial satellites allows scientists to use space telescopes to avoid atmospheric turbulences. In this way, they are able to receive images that are impossible to receive directly on the Earths surface. The well-known Hubble telescope, launched into space in 1990, operates in the visible and UV spectrum. The main part of this telescope consists on a spherical mirror of 2.4 m diameter, as shown in the photo below.
Another technology used in this regard are the spatial probes. These cosmic machines carry on-board all the necessary tools required for the observation and analysis of celestial objects. They usually make a one-way journey from the Earth to other celestial bodies, they don't return back to the Earth so they continiously transmit the images and videos obtained during their flight. This occurs for several year until they are lost in the space and cannot send information back to the laboratories on Earth.
