Square hole in Sun stumps NASA

So much more is still to be learnt about the universe. We know just a fraction of it. Square hole in Sun has surprised NASA

Astronomers have found coronal holes in the Sun. They spotted the holes after they noticed that the magnetic field was allowing hot plasma to fly off into space toward Earth.

Since then the coronal hole has been occurring less. The experiencing of a solar maximum has been attributed to the phenomenon. However what is disturbing is that the coronal holes increase in size and number. It is understood that in coming days it would extend further from the poles as the sun moves toward solar minimum again.

Scientists, who have been observing the Sun for some time, have reported that in the past they have spotted coronal holes. But the different is that they have been found to be even larger than the existing one. How are they formed? This and other questions have been doing the rounds sine square hole in the Sun has been spotted.

The source of the hole goes back to a high-speed wind of solar particles. The hole whose picture was only seen last week has been identified as the most noticeable features on the Sun. Further study and observation of the hole by NASA scientists is certainly going to throw new lights on it.
