# Here’s the Closest Picture We’ve Ever Taken of the Sun

## Solar Flyby

Earlier this year, NASA's Parker Solar Probe flew [extremely close](<https://www.nasa.gov/feature/goddard/2018/parker-solar-probe-reports-good-status-after-close-solar-approach>) to the Sun.

Its approach brought it within 15 million miles — far closer than the planet Mercury — from the Sun's surface, traveling at 213,200 miles per hour, which is the [fastest](<https://blogs.nasa.gov/parkersolarprobe/2018/10/29/parker-solar-probe-becomes-fastest-ever-spacecraft/>) any man-made spacecraft has ever traveled.

And today, we get to see a glimpse of what the Sun's surface and outer atmosphere looks like at that distance.jup

"Parker is an exploration mission — the potential for new discoveries is huge," says Nour Raouafi, Parker Solar Probe project scientist at the Johns Hopkins University.

Here's the picture in its full glory:

Luckily, NASA has some [clarifying words](<https://www.nasa.gov/feature/goddard/2018/preparing-for-discovery-with-nasas-parker-solar-probe>) about what we're looking at. The image shows a so-called coronal streamer crossing the "east limb of the Sun." Oh, and that big white spot in the middle? That's Mercury, in the background.

The corona is the Sun's outer atmosphere, which is visible to the untrained eye [during a total solar eclipse](<https://spaceplace.nasa.gov/sun-corona/en/>). Coronal streamers occur when more than the usual quantity of solar particles are released from the Sun's solar winds.

The Parker Solar Probe had to travel very quickly to get such a clear view. The Sun rotates once every 27 days, meaning that any spacecraft near it has to keep up, especially given the Sun's massive size.

## Some Big Questions

NASA's Parker Solar Probe is trying to answer some [pretty big questions](<https://www.nasa.gov/feature/goddard/2018/preparing-for-discovery-with-nasas-parker-solar-probe>) about our star: why is the corona so hot compared to the surface below it? How does solar wind accelerate so quickly? How do the Sun's most energetic particles shoot away from the Sun at more than half the speed of light?

Thanks to the Parker Solar Probe, we will soon know a lot more about the underlying physics of that big blob of hot plasma at the center of our solar system.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
