Back in 2017, a large new area of magnetic field exploded on the Sun’s ground close to an already present sunspot. The crash of the magnetic energy was so mighty that it made a bunch of capable solar flares. They also caused some chaotic space weather situations on Earth.
Such actions were the recognized as the first flares to be identified and captured, in their step-by-step continuous evolution, by NJIT’s EOVSA radio telescope (Expanded Owens Valley Solar Array).
In a recently published study, the researchers who registered those pictures have pinpointed for the first time its time and place where the crash dismissed energy. Such energy that warmed spreading plasma to strengths qual to almost 1 billion degrees.
New Radio Telescope Succeeds to Capture an intriguing Phenomenon
EOVSA’s 13 antennas shot photos at hundreds of frequencies in the 1-18GHz level, such as X-rays, optical, radio wavelengths, and ultraviolet within a second. That improved skill to gaze into the mechanics of flares starts a new way to examine the most regular eruptions in our solar system, which are fueled by the restoration of magnetic field marks on the Sun’s ground and conducted by stored energy in its corona.
“Microwave emission is the only mechanism that is sensitive to the coronal magnetic field environment, so the unique, high-cadence EOVSA microwave spectral observations are the key to enabling this discovery of rapid changes in the magnetic field,” stated Dale Gary, from NJIT.
Before researchers had the EOVSA’s examination, there was no other method to gaze into the broad area of space in which high-energy fragments are accelerated. They become then accessible for advanced acceleration by the mighty shock wave conducted by the flare burst, which, if pointed towards our planet, can threaten astronauts and damage spacecraft.
