Sunspot News
Researchers including those from European Southern Observatory (ESO), produced the images as a demonstration of ALMA’s ability to study solar activity at longer wavelengths of light than are typically available to solar observatories on Earth.
However, to achieve a fuller understanding, astronomers need to study it across the entire electromagnetic spectrum, including the millimetre and submillimetre portion that ALMA can observe.
Sunspots, also known as Solar Lentigines, usually affect people with lighter skin, but anyone can get them.
Sunspot regions are areas of intense magnetism so that plasma is being pulled along magnetic field lines between areas of opposite polarity.
