Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming from the Milky Way .
Radio frequencies at non-ablation energy levels are commonly used as a part of aesthetic treatments that can tighten skin, reduce fat by lipolysis and also apoptosis, [4] or promote healing. [5] RF diathermy is a medical treatment that uses RF induced heat as a form of physical therapy and in surgical procedures. It is commonly used for muscle ...
Ground-based radio astronomy is limited to high altitude sites such as Kitt Peak and Atacama Large Millimeter Array due to atmospheric absorption issues. Satellite-based remote sensing near 60 GHz can determine temperature in the upper atmosphere by measuring radiation emitted from oxygen molecules that is a function of temperature and pressure.
The Medicina Radio Observatory is an astronomical observatory located 30 km from Bologna, Italy. It is operated by the Institute for Radio Astronomy of the National Institute for Astrophysics (INAF) of the government of Italy. The site includes: 32-metre diameter parabolic antenna for observing between 1.4 and 23 GHz.
Other ground and space-based telescopes were used for follow-up observations of the newly discovered object, including the MeerKAT radio telescope in South Africa and the XMM-Newton space ...
The term is used in the following major meanings: study of radio waves (the original area of research) study of radiation used in radiology [2] study of other ranges of the spectrum of electromagnetic radiation in some specific applications; Among the main applications of radiophysics are radio communications, radiolocation, radio astronomy and ...

The Mark II telescope is an elliptical radio telescope, with a major axis of 38.1 metres (125 ft) and a minor axis of 25.4 metres (83 ft). [36] It was constructed in 1964. As well as operating as a standalone telescope, it has been used as an interferometer with the Lovell Telescope, and is now primarily used as part of the MERLIN project.
