[동포투데이 철민 기자] The US National Aeronautics and Space Administration (NASA) recently released a satellite image showing the “smiley face” of the sun’s surface, which has been popular on US social networking services (SNS), US Business Insider reported. .com on 29.
This photo was taken by NASA’s Solar Dynamics Observatory research program to understand changes in solar radiation output. The released photo shows three black dots on the sun’s surface, resembling a pair of eyes and a smiling mouth.
The official NASA account @NASASun said, “Today NASA’s Solar Dynamics Observatory captured the ‘smile’ area of the sun to come,” he explained.
This area reportedly appears as a dark spot in the observational image because it is typically cooler and less dense than the surrounding area.
According to the American scientific journal Life Sciences, corona holes can form at any time, but they cannot be seen with the naked eye or with a home telescope and can only be seen with ultraviolet and X-rays.
The photo has become a topic of discussion among Twitter users, for example by comparing it with the “smiling sun” of the “Teletubbies” children’s program or with a Halloween pumpkin.
However, some argue that there may be dangers behind this interesting astronomical phenomenon. Space media, Spaceweather.com, explained that the corona void could be a sign that a geomagnetic storm could occur between October 29-30.
