A new image of the Sun, captured by the world's largest solar telescope, has revealed the surface of our nearest star in unprecedented detail, writes A2 CNN. The image is the first to come from the Visible Tunable Filter (VTF) of the Daniel K. Inouye Solar Telescope in the US. This advanced instrument allows for the construction of a three-dimensional view very close to what happens on the surface of the Sun.
The image shows a cluster of continent-sized dark spots located in the Sun's inner atmosphere, with a resolution of 10 kilometers per pixel. These spots, known as sunspots, are areas of intense magnetic activity where massive solar flares can occur.
These bursts directly affect planet Earth, interfering with electrical grids and satellite communications. Understanding these phenomena is essential for predicting space weather and protecting our technology.
The telescope uses a sophisticated filtering technique through two closely spaced glass plates that allow the selection of certain wavelengths of light. This allows scientists to study different layers of the solar atmosphere and measure the temperature, pressure, magnetic field, and movements within it.
The instrument is expected to be fully operational by 2026, and is considered the “heart” of the Inouye Telescope. This development marks a giant step towards a deeper understanding of the Sun and its influence on Earth. (A2 Televizion)
