Spotted by Nasa’s solar Dynamics Observatory (SDO), an orbiting satellite saw the growth on the star’s northern hemisphere.

NASA news came a few days ago with an image showing a giant dark hole on the Sun’s surface. It is called the coronal hole and according to the USA space agency, these holes are indicators of low-density areas where the star’s magnetic field opens up to the interplanetary space.
The presence of holes in Sun is a natural phenomenon as they tend to pop up on Sun’s surface from time to time and they are called coronal holes.
The hole on the sun’s surface is actually an astronomical event that appears on the star’s atmosphere every now and then. Because of this, the areas have much less hot plasma than their hotter, brighter surroundings, causing them to appear dark and, well, “hole-y”. As a result, it emits much less radiation than other areas, causing it to appear as a dark spot.
A breathtaking image was released by NASA, spotting massive hole that spreads across the surface of the sun.

Sun’s coronal holes are the source of high-speed wind of solar particles. However, it may lead to several problems on Earth, such as, Global Positioning System errors, disrupt radio signals or communication, HuffingtonPost reported. Huffington Post noted that Solar Winds could be released from the corona and form solar storms, which can disrupt satellite and radio communication systems. The spacecraft’s high-definition photos are helping researchers better understand the sun’s magnetic field and solar activity, including how and why that activity varies over time.
