Sun’s surface up close: Stunning video shows extreme details of Sun’s corona


NEW DELHI: A recent detailed video taken by the Solar Orbiter spacecraft of the European Space Agency revealed the appearance of the Sun’s surface.
The shared video showed a detailed view of the Sun’s surface, depicting the transition from the star’s lower atmosphere to its corona, which frequently releases massive amounts of coronal material.
In the video a bright ray of light can be observed, resembling the way a light ray shines through trees in a forest.These rays, which are similar to hair-like structures, consist of plasma and represent magnetic field lines originating from the star’s interior.
Spicules, the gas rays, can reach sizes of up to 6,214 miles or nearly 10,000 km from the Sun’s chromosphere.

The European Space Agency said at the brightest spots in the video can reach temperatures as high as one million degrees Celsius, while the dark spots show where radiation is absorbed.
In the lower-left corner of the video, you see some patterns caused by bright gas which the agency calls coronal ‘moss’, which are often found near large coronal loops that are currently invisible to the solar probe.
At the 22-second mark, a small eruption is visible in the center. Although these eruptions may appear small in the video, the European Space Agency states that they are larger than the Earth. They demonstrate how cooler material rises up and then descends due to the Sun’s immense gravitational force.
The video taken by the solar probe is currently at a distance equivalent to one third of the total distance between the Sun and Earth. The space agency intends to move it even closer to the star.
