Parker Solar Probe Captures Closest Ever Photos of the Sun

NASA’s Parker Solar Probe Captures Closest Ever Photos of the Sun’s surface, uncovering new truths about solar wind, CMEs, and space weather mysteries.

What’s the story

On December 24, 2024, NASA’s Parker Solar Probe flew closer to the sun than anything ever has—just 6.1 million kilometers away. For the first time, it sent back jaw-dropping images from within the sun’s corona, giving scientists a rare look at the origin of solar wind and giant blasts of plasma called coronal mass ejections (CMEs). These winds can mess with power grids and GPS systems on Earth. What’s wild is that the probe survived temperatures above 1,370°C and deadly radiation to send us this data. Since its launch in 2018, Parker Probe has circled the sun 23 times. This mission is helping answer the big question: How does solar wind form, and why does it get so strong? Now, the entire world, including scientists in India, is watching with wonder.

Wind behavior
Solar winds behave differently near the sun

When you feel wind on Earth, it’s air moving. But space wind is way weirder. Near the sun, it’s a burst of charged particles moving at over 1.2 million km/hour! On Earth, we mostly get the steady version. But thanks to the Parker Solar Probe, scientists now see how wild it gets closer in. These aren’t breezes—they’re super-fast streams that slam into magnetic fields, causing switchbacks, or zigzag patterns. Around 14.7 million miles (23.6 million km) from the sun, things get crazy. NASA noticed that the solar wind comes in different speeds—fast ones up to 800 km/sec and slower, denser ones that behave like random gusts. And India’s own space experts from ISRO are using this to better understand how solar radiation could impact future space missions like Gaganyaan. What used to be just theory is now confirmed through real pictures and patterns. That’s a big deal for anyone studying space weather.

Plasma storms
Giant plasma clouds are crashing into each other

One of the most intense things the Parker Probe spotted during its December 2024 flyby were CMEs—huge clouds of plasma flung off the sun’s surface. These aren’t small puffs. Some carry as much mass as Mount Everest and fly at 3,000 km/second! The probe captured something brand new—CMEs slamming into each other right after being launched. These pileups, seen through the Wide Field Imager for Solar Probe (WISPR), could help explain why some storms in space get more intense. On Earth, these merged CMEs can cause blackouts or mess with satellites. For instance, a CME in 2022 knocked out 40 Starlink satellites. That’s no joke. Understanding these plasma interactions is key to improving space weather forecasts. As per NASA and Johns Hopkins Applied Physics Lab, the Parker Probe has now confirmed that these space storms aren’t isolated—they can combine, amplify, and head straight toward us like a cosmic cannonball.

Funnel paths
Fast solar wind comes from cooler sun regions

Not all solar wind comes from the same spot. That’s what makes the sun so tricky. The Parker Probe found that fast solar wind is being shot out of magnetic funnels in the sun’s cooler zones, called coronal holes. These holes aren’t really holes—they’re dark spots that look like sun freckles. Fast winds from here hit up to 800 km/sec and fly straight out with zigzag patterns, known as switchbacks. Earlier, we only guessed that these funnels powered solar wind. Now we’ve got proof. These regions are like open doors in the sun’s atmosphere, and they let energy out in focused jets. In 2024, this confirmed what scientists at NASA and ScienceAlert were suspecting for years. For India’s researchers, this helps create stronger solar models. When ISRO preps satellites or lunar craft, knowing where the blast zones on the sun are can help design safer tech. It’s like dodging potholes—except in space.

Wind twins
There are two types of slow solar wind

Here’s a twist: slow solar wind comes in two flavors—Alfvénic and non-Alfvénic. The Parker Probe finally confirmed this old theory. Alfvénic winds have magnetic waves that behave like switchbacks, while the non-Alfvénic type flows like syrup, heavier and less predictable. Scientists think Alfvénic slow wind might come from the same coronal holes as fast wind, just with lower energy. Non-Alfvénic ones? They’re likely from “helmet streamers,” the big loops seen on the sun’s surface. These loops are hot and chaotic, and when they release wind, it’s bumpy. Think of it like two rivers—one wild, one lazy—but both coming from the same mountain. According to NASA’s Adam Szabo, these details now help us match solar weather to its source. For India’s growing space interests—like upcoming Venus missions—this split helps engineers protect electronics from slow but sneaky solar blasts.

Corona dive
First probe to fly inside the sun’s atmosphere

The Parker Solar Probe isn’t orbiting the sun from afar—it’s actually diving into its outer atmosphere, the corona. No spacecraft has done that before. In 2021, it crossed the Alfvén critical surface—the invisible line where the sun’s gravity stops controlling the solar wind. But in 2024, during its 17th orbit, the probe flew deeper, just 6.1 million km from the surface. It’s flying through temperatures over 1,370°C while moving faster than any human-made object ever—over 586,000 km/hour! With instruments like SWEAP and WISPR, it’s scanning the sun’s magnetic fields, particles, and heat. This close-up mission is unlocking how particles escape the sun. Imagine flying through a tornado and taking selfies—except this one’s made of fire. Thanks to this daring flight, scientists are learning more about the structure of the corona than ever before. According to NASA, the deeper dives are turning theories into solid data.

Magnetic chaos
Switchbacks twist wind into strange patterns

Closer to the sun, the solar wind doesn’t move in a straight line. It zigzags wildly due to magnetic switchbacks. These sudden flips in magnetic direction were first spotted in 2019, but Parker’s latest pass showed they’re everywhere near the surface. Some switchbacks stretch thousands of kilometers. Think of it like a kite string tangled in wind. Why does this matter? Because these patterns add extra push to solar wind. This means that the sun isn’t just leaking particles—it’s tossing them with force. These bursts affect satellites and astronauts. A switchback storm could force a delay in future moon missions. NASA now believes these switchbacks are a big part of what accelerates fast solar wind. Understanding them is helping both Indian and global scientists figure out how to design better space shields. As per ScienceAlert, this makes Parker’s findings crucial for future Mars or deep-space missions.

Earth impact
Solar storms can cause blackouts and GPS fails

These fiery winds don’t just stay in space. When CMEs or intense solar wind hit Earth, they can trigger big problems. In 1989, a solar storm blacked out Quebec for 9 hours. In 2022, 40 Starlink satellites were lost after one hit. The Parker Probe is helping spot these events before they reach us. One CME can carry over 10 billion tons of plasma and create currents in Earth’s atmosphere. These currents can damage power lines, disrupt GPS, and even mess with mobile networks. According to the Indian Institute of Geomagnetism, strong solar winds have caused GPS glitches over South India in the past. With more of us depending on smartphones and satellites, even a small solar hiccup matters. Thanks to Parker’s data, we’re building better early-warning systems. Just like IMD tracks cyclones, we may soon track solar storms and issue space-weather alerts.

Future science
How data could shape India’s space plans

India is aiming high with missions like Gaganyaan and Shukrayaan, and Parker Probe’s discoveries are helping shape how ISRO prepares. With better understanding of fast and slow solar winds, Indian engineers can now build radiation-hardened spacecraft. For example, data from Parker helps decide what kind of shielding a human crew might need for Gaganyaan. Also, tracking CMEs helps plan launch windows, so missions don’t lift off during high solar activity. The Indian Space Research Organisation has already partnered with NOAA and NASA for space weather forecasting. As India gears up to become a bigger player in space, every bit of this research counts. According to Times of India, ISRO scientists are using Parker’s findings in planning future satellite networks that can survive solar outbursts. The sun might be 150 million kilometers away, but what it does affects us every day.

Data goldmine
Every image adds new pieces to the puzzle

NASA’s Parker Solar Probe has sent back over 2.8 terabytes of raw solar data since its launch. That’s like streaming 700 HD movies non-stop. Each flyby gives a clearer look into the sun’s wild behavior. Researchers are seeing new things in almost every image—from plasma bubbles to invisible boundaries where wind suddenly changes. The December 2024 images showed CMEs crashing together, something only guessed at before. “We’re not just seeing the sun—we’re watching how it breathes,” said Angelos Vourlidas, the WISPR instrument scientist. These visuals are changing textbooks, not just tweaking them. With every pass, the probe is drawing a clearer map of the corona’s behavior. The next perihelion in September 2025 could bring even more shocking images. And guess what? Some of this data is open-source, meaning even student scientists in India can explore it. We’re in a golden age of sun science, and Parker Probe is leading the way.

Discovery boost
Why this mission is bigger than one probe

The Parker Probe isn’t flying alone in this mission. It’s helping trigger a wave of new studies. ESA’s Solar Orbiter, launched in 2020, is also now working alongside Parker to compare data and cross-check patterns. By combining views from different angles, researchers can see the sun in 3D for the first time. That’s helping explain things like “solar tsunamis”—giant waves in the sun’s atmosphere that were once a mystery. Back home, India’s Aditya-L1 mission, launched in 2023, is also adding local data to this global network. Combining info from Parker, Aditya, and other missions helps build a space-weather system much like we do for cyclones. According to the Hindustan Times, collaboration across countries is now key. Just like tracking a cyclone needs multiple satellites, understanding solar threats needs all hands on deck. It’s not just NASA’s job anymore—it’s a global science mission.
