NASA Spacecraft Detects Large Square Hole In The Sun
NASA's Solar Dynamics Observatory (SDO) has detected a bizarre square-shaped hole in the sun's upper atmosphere, the first of its kind ever to be recorded. The large square dark patch is actually a coronal hole, an area of the star that sees high-speed solar winds pouring out of its atmosphere.
While significant ejections of solar-winds like this can often have an impact on us here on Earth, NASA scientists believe we will be spare from this particular event.
'Inside the coronal hole you can see bright loops where the hot plasma outlines the little pieces of the solar magnetic field sticking above the surface," says NASA's SDO site. "Because it is positioned so far south on the Sun, there is less chance that the solar stream will impact us here on Earth"
Dark spots appear in videos such as these because they display a lower density of material that can be detected by the spacecraft's ultraviolet camera systems. But while the SDO team are confident in the cause for the hole's appearance, the fact that it has formed in such an angular nature is more perplexing.
