The Glasgow CALLISTO spectrometer
detects radio emissions from the Sun between 45 - 80 MHz from 07:15 UT until 15:00 UT on a daily basis.
«The mere fact that
they detected radio emission is remarkable,» said Tim Bastian, an astronomer at the NRAO in Charlottesville, Virginia, who added that this object «will likely have something to teach us.»

Rampadarath explains: «Comparing the VLA images at
radio wavelengths to Chandra's X-ray observations and the hydrogen -
emission detected by Hubble, shows that features are not only connected, but that the
radio outflows are in fact the progenitors of the structures seen by Chandra and Hubble.
However, until now,
radio telescopes have only been able to
detect the
emission signature of hydrogen from relatively nearby galaxies.
And just as we can regard
radio emissions as waves and not as photons because of their long wavelength, the gravitational waves that we
detected were of sufficiently long wavelength that we could indeed regard them as waves.
Breakthrough Listen allotted tens of hours of observational time on the Green Bank Telescope to recording
radio emissions from FRB 121102, and last August 26
detected 15 bursts over a relatively short period of five hours.
«
Radio emissions from the regions in which clusters collide were first
detected almost 20 years ago, but no one was able to explain how electrons could be accelerated to the point where they emitted radiation in this frequency band.
Together, the telescopes create a virtual dish 9000 kilometers wide that can
detect the faintest
radio emissions from distant galaxies.
Over the past few years, advances in the development of software defined
radio (SDR) have encouraged tinkerers to construct low - cost
radio telescopes suitable for
detecting emission from galactic neutral hydrogen.
In addition to
detecting the bright bursts from FRB 121102, the VLA observations also revealed an ongoing, persistent source of weaker
radio emission in the same region.
Water
Emissions - In September of 2002, a team of astronomers (including Cristiano Cosmovici of the Institute for Cosmic and Planetary Science) announced at the Second European Workshop on Exo / Astrobiology that they had detected water «maser» emissions from three of 17 star systems suspected of hosting planets, including Upsilon Andromedae, using the 32 - meter Medicina radio telescope near

A group of summer students making a long - shot astronomical gamble with the National Science Foundation's (NSF) Very Large Array (VLA) have found the first
radio emission ever
detected from a brown dwarf, an enigmatic object that is neither a star nor a planet, but something in between.
The team of researchers used measurements of
radio emissions, taken by the Atacama Large Millimeter Array (ALMA) in the desert of northern Chile, starting in 2015, to
detect and map signs of cold gas in the Phoenix cluster.
Rather than using radar equipment to
detect astronomical objects, Lovell soon realised that collecting
radio emissions from celestial objects offered far more potential for astronomical research.
Radio telescopes are able to detect the naturally occurring radio emission from neutral atomic hydr
Radio telescopes are able to
detect the naturally occurring
radio emission from neutral atomic hydr
radio emission from neutral atomic hydrogen.
By
detecting this pulsar in the
radio spectrum, astronomers may now follow its evolution with greater ease and flexibility than with X-ray telescopes on satellites, study the pulsar
emission mechanisms, and also characterize the dynamic interstellar medium between the Earth and the pulsar.
ALMA's unprecedented sensitivity enables us to
detect weak
radio emissions which are undetectable by other telescopes.
The GBT is uniquely designed to
detect extremely faint
radio emissions from the distant universe.
