We've detected a star barely hotter than a pizza oven—the coldest ever found to emit radio waves
We have identified the coldest star ever found to produce radio waves—a brown dwarf too small to be a regular star and too massive to be a planet.

Using the upgraded Giant Meterwave Radio Telescope (uGMRT), astronomers from India and Australia have performed radio observations of a pulsar known as PSR J0026–1955. Results of the observational campaign, published July ...
Astronomers have used a newly upgraded world-leading radio telescope to unbury the radio emissions from a galaxy cluster known as CIZA1359. The signal has until now been buried in noise from a nearby foreground object.
