A solar eclipse was recorded by the Solar Dynamics Observatory (SDO), of Nasa, this Wednesday (29). Basically the Moon passed between the Sun and the Observatory Lookout, covering 67% of our star and, on the other hand, having its mountains illuminated by the farthest light – like a spatial “backlight effect”.
The SDO was launched in February 2010 and its mission is to observe the “solar climate” – a term used to refer to the radiation which comes from the celestial body towards free space and which affects the Earth in various ways. The object studies various factors of the Sun, such as its magnetic field, sunspots and coronal ejections which fluctuate in intensity over the 11-year cycle of solar activity.
Today’s event had no major implications beyond just a simple pass of the Moon in front of the Sun (although, let’s face it, a solar eclipse provides a visual spectacle whenever it’s correctly recorded).
Solar winds are normally charged with highly energetic particles, but most of the time they don’t cause us much trouble. Particularly strong discharges can cause noticeable visual effects such as northern Lights.
However, particularly intense coronal ejections can affect satellites and other artifacts with electronic components. There are even those who theorize that a possible “internet apocalypse” could be caused by really large coronal mass ejections.
The SDO is not the only object positioned by NASA in the region of the Sun: the spacecraft solar orbiter is also in the area, making several observations about our “star-king” and has already sent us back some great pictures and videos.
