NASA investigates mysterious signal from the sun

Scientists first detected mysterious signals from the sun decades ago. These signals were transmitted through space in the form of radio waves.

So far, experts have determined that they come from flares and large eruptions on the sun called coronal mass ejections (CMEs), according to Futurism on July 11.

CMEs are the source of solar storms that can disrupt satellite operations and technology on Earth. However, no one knows where the mysterious signal from a CME event originates.

The CURIE mission, deployed by NASA, uses a technology called low-frequency radio interferometry, which has never been used in previous space missions.

CURIE relies on two independent CubeSats, operating in Earth orbit about 3.6 km apart. This distance allows CURIE's instruments to measure the smallest differences in the arrival time of mysterious radio waves to Earth, thereby localizing the origin of this mysterious signal.

“This is an ambitious and incredibly exciting mission,” said project principal investigator David Sundkvist, a researcher at the University of California at Berkeley.

The mission marked the first time an agency had used radio interferometry in a controlled manner in space, paving the way for later radio astronomy techniques, he said.
