The sun may too bright and too powerful for us to look at with the naked eye, even from nearly 92 million miles away on Earth, but a solar orbiter recently got an unprecedented up-close glimpse of ...
The images, taken on March 22, 2023, and released Wednesday, showcase different dynamic aspects of the sun, including the movements of its magnetic field and the glow of the ultrahot solar corona ...
The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.
Features as small as 30km (18 miles) in size are observable for the first time. The image shows a pattern of turbulence of solar plasma, a super-heated gas. The cell-like structures, each about the size of Texas (approximately 700'000km 2), are the signature of a dynamic activity of heat from the inside of the sun to its surface. The solar ...

A photo shared by users across social media claiming to show the closest image of the sun's surface is heavily edited and was not captured by NASA.
The High Resolution Coronal Imager (Hi-C) is a sub-orbital telescope designed to take high-resolution images of the Sun's corona. As of 2020 [update] it has been launched three times, but only the first and the third launches, on July 11, 2012, and May 29, 2018, resulted in a successful mission. [ 1 ]
Sunlight on the surface of Earth is attenuated by Earth's atmosphere, so that less power arrives at the surface (closer to 1,000 W/m 2) in clear conditions when the Sun is near the zenith. [100] Sunlight at the top of Earth's atmosphere is composed (by total energy) of about 50% infrared light, 40% visible light, and 10% ultraviolet light. [101]
