A NASA A satellite captured a happy face on the sun earlier this week, prompting the US space agency to say the sun was seen “smiling”.
The agency posted the image on Twitter on Wednesday: “Today, NASA’s Solar Dynamics Observatory caught a ‘smile’ at the Sun. Seen in ultraviolet light, these dark patches on the Sun are called coronal holes, and are regions where the fast solar wind escapes into space.
NASA’s Solar Dynamics Observatory is an enterprise mission aimed at investigating how solar activity generates and drives space weather. First launched on 11 February 2010, the observatory’s spacecraft measure the Sun’s interior, atmosphere, magnetic field and energy output.
Since its release, the NASA photo has sparked a number of reactions online, with many comparing the image to a carved Halloween PumpkinA the lion And this the sun Featured in the children’s show Teletubbies.
A user replied: “That’s the stay puff face[t] The Marshmallow Man from Ghostbusters?”

Despite its friendly appearance, experts warn that the sun’s coronal holes could mean a solar storm hitting Earth on Saturday. Spaceweather.com said: “Happy Maine [sic] Three times the solar wind blows towards Earth.
Solar storms are various explosions of mass and energy from the Sun’s surface that disrupt Earth’s magnetic field. As a result, these storms increase the visibility of the polar lights, also known as auroras, in both the northern and southern hemispheres.
