Closest ever photograph of the Sun revealed

NASA's groundbreaking Parker Solar Probe has taken a close-up shot from inside the Sun's corona.
Taken at a distance of 16.9 million miles using the probe's WISPR (Wide-field Imager for Solar Probe) instrument, the impressive image shows two jets of solar material known as coronal streamers.

The bright spot near the center is the planet Mercury, while the dark spots are image artefacts from background correction.

"Coronal streamers are structures of solar material within the Sun's atmosphere, the corona, that usually overlie regions of increased solar activity," NASA wrote.

"The fine structure of the streamer is very clear, with at least two rays visible. Parker Solar Probe was about 16.9 million miles from the Sun's surface when this image was taken."
The spacecraft itself, which launched back in August, will ultimately complete a total of 24 loops around the Sun over the next seven years.

At its closest approach, it will venture a mere 3.83 million miles from the Sun's surface.

"We don't know what to expect so close to the Sun until we get the data, and we'll probably see some new phenomena," said project scientist Nour Raouafi.

"Parker is an exploration mission - the potential for new discoveries is huge."

Im curious... how could the probe†withstand the temperatures? Do we have material that can withstand that? It must be in excess of a million degrees and hotter the closest it gets.†

Yes NASA do know and have explained them Note the photos are from a probe, what could you possibly have to better what NASA have done?†

Yep. Cringeworthy comments indeed.† People can be†so†ignorant to how amazing these type of things are. Itís such†an great†achievement! Itís like they think NASA comes up with an idea†over beers and then executes it the next weekend.†

Pretty amazing photo and to think the probe is going to get allot closer to the sun in the course of its mission hopefully allot more photos to come.

In other words, another standard UM thread.
