Well the answer is the science of radio astronomy.

The Sun produces various types of radio emissions, so spectrometers such as CALLISTO are necessary to identify the nature of coherent solar radio emissions from solar eruptions, relevant to space weather.

This range makes the jansky a suitable unit for radio astronomy.

Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky.

Jansky's careful listening ushered in a new age of space exploration the radio astronomy age.

Tesla has over 700 patents to his name radio, wireless telegraphy, remote control, robotics.

Occurrence of these bursts marks the formation of shocks near the Sun, which might arrive at Earth after a few days and mark the start of geomagnetic storms.

And that, of course, that set back the progress of radio astronomy by about 20 years.

The tally of molecules discovered through radio astronomy is steadily increasing at the rate of about four new species per year.

This part of the radio spectrum ranges across frequencies of roughly 1.0 gigahertz (GHz) to 30 GHz.

This network, called the Radio Solar Telescope Network (RSTN), uses a bandwidth from 25 MHz to 85 MHz.

It was created for and is still most frequently used in reference to electromagnetic energy, especially in the context of radio astronomy.

Fifty years on from Watson's accidental encounter with the Sun, Jansky's careful listening ushered in a new age of space exploration the radio astronomy age.

Opportunities are being explored to install a low frequency radio telescope at the Gauribidanur radio telescope site in India to work in conjunction with CALLISTO in Ooty.

One of the important types of radio emissions occurring in the CALLISTO spectral range are the shock related radio bursts known as type II radio bursts.

The development of radio astronomy, infrared astronomy and submillimetre astronomy in the 20th Century allowed the gas and dust of the Milky Way to be mapped for the first time.

Well, of course, as soon as anybody did look, which was after about 20 years, when radio astronomy really took off.

Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky.

He showed, in 1946, that the radio wave radiation from the Sun emanates from the ionized layers of its corona, and he developed a mathematical method for discriminating between thermal and nonthermal radio waves in the Milky Way.

In the case of NAA transmission, the path over Puerto Rico should also be noted, where ionospheric radio measurements are made at the Arecibo (18 30 N 68 31 W) radio facilities in association with the sprites phenomena.

The radio spectrum is the part of the electromagnetic spectrum from 8.3 kHz to 3000 GHz allocated to some 40 Radiocommunication services in line to the Radio Regulations (RR) of the International Telecommunications Union (ITU).

The International Radioastronomical Centre of Ventspils University College is participating in two projects within the Sixth Framework Programme the European radio astronomy programme RadioNet and Express Production Real Time electronic Very Long Baseline Interferometry Service.

At the same time, research and tests that were carried out for 406 MHz ELTs demonstrated that technical requirements for such beacons could be relaxed without affecting system performance, allowing for lower cost designs.

Cognitive radio technology, also known as smart radio allowing different radio technologies to share the same spectrum efficiently by adaptively finding unused spectrum and adapting the transmission scheme to the requirements of the technologies currently sharing the spectrum.

Well, of course, as soon as anybody did look, which was after about 20 years, when radio astronomy really took off. Because it turned out the universe is absolutely full of all kinds of wonderful things radiating in the radio spectrum, much brighter than the Sun.
