uGMRT uncovers the signature of a cannon ball fired from the Sun, using pulsars!

A group of nearly 20 astronomers, under the banner of Indian Pulsar Timing Array (InPTA), have for the first time detected the effect of a Coronal Mass Ejection (CME) from the Sun in the signal from a millisecond pulsar using the upgraded Giant Metrewave Radio Telescope (uGMRT). This space weather effect on a pulsar from the Sun is the first of its kind ever reported. This was possible only due to unique wideband and low frequency capabilities of the uGMRT.
