One mystery in our universe is a step closer to being solved. NASA's Parker Solar Probe launched last year to help scientists understand the sun. Now, it has returned its first findings. Four papers were published in the journal Nature detailing the findings of Parker's first two flybys. It's one small step for a solar probe, one giant leap for mankind.
It is astounding that we've advanced to the point where we've managed to build a probe capable of flying within 15 million miles from the surface of the sun, but here we are. Parker can withstand temperatures of up to 2,500 degrees Fahrenheit and travels at 430,000 miles per hour. It's the fastest human-made vehicle, and no other human-made object has been so close to the sun.
Scientists are hoping Parker gives them insight into two mysteries. Why is the corona hotter than the sun's surface? And how does solar wind reach such an incredible speed? We're starting to get answers to these questions.

We finally know what speeds up solar winds. "We'd see suddenly a spike in flow, where in just a couple seconds the solar wind would start flowing 300,000 miles an hour faster," Justin Kasper, lead author of one of the studies, said.
"Sometimes these spikes, or stronger waves, last for a couple seconds, sometimes they last for hundreds of seconds," Kasper said. "But they nearly double the speed of the solar wind, and they are so violent that they actually flip the direction of the magnetic field in the solar wind around."
We also have insights into what solar wind actually looks like. "We see that the solar wind is very bursty," Stuart Bale, of the University of California at Berkley, said. "It's bubbly. It's unstable. And this is not how it is near Earth." The solar probe observed about 1,000 of those bubbles and bursts in 11 days. Researchers were so surprised by the solar winds, they though the instruments were malfunctioning.

Parker also helped validate a theory long-held by scientists. It was conjectured that a cosmic dust-free zone surrounds the sun, the logic being the sun would vaporize the residue of planets and asteroids orbiting around the sun. The solar probe found that dust gets thinner closer to the sun, just not the way they thought. "What was a bit of a surprise is that the dust decrease is very smooth," Russell Howard, another astrophysicist working with the probe, said. "We don't see any sudden decreases indicating that some material has evaporated."
The information gleaned from Parker can also help scientists understand and predict solar storms, which sometimes disrupt artificial satellites. These insights could be used to help protect astronauts and satellites in the future.
Parker will study the sun for the next six years. Who knows what mysteries will be solved, and what new mysteries will be created?

Grieving couple comforting each other
This response to someone grieving a friend might be the best internet comment ever
When someone is hit with the sudden loss of a friend or loved one, words rarely feel like enough. Yet, more than a decade ago, a wise Redditor named GSnow shared thoughts so profound they still bring comfort to grieving hearts today.
Originally posted around 2011, the now-famous reply was rediscovered when Upvoted, an official Reddit publication, featured it again to remind everyone of its enduring truth. It began as a simple plea for help: “My friend just died. I don't know what to do.”
What followed was a piece of writing that many consider one of the internet’s best comments of all time. It remains shared across social media, grief forums, and personal messages to this day because its honesty and metaphor speak to the raw reality of loss and the slow, irregular path toward healing.
Below is GSnow’s full reply, unchanged, in all its gentle, wave-crashing beauty:
Why this advice still matters
Mental health professionals and grief counselors often describe bereavement in stages or phases, but GSnow’s “wave theory” gives an image more relatable for many. Rather than a linear process, grief surges and retreats—sometimes triggered by a song, a place, or a simple morning cup of coffee.
In recent years, this metaphor has found renewed relevance. Communities on Reddit, TikTok, and grief support groups frequently reshare it to help explain the unpredictable nature of mourning.
Many readers say this analogy helps them feel less alone, giving them permission to ride each wave of grief rather than fight it.
Finding comfort in shared wisdom
Since this comment first surfaced, countless people have posted their own stories underneath it, thanking GSnow and passing the words to others facing fresh heartbreak. It’s proof that sometimes, the internet can feel like a global support group—strangers linked by shared loss and hope.
For those searching for more support today, organizations like The Dougy Center, GriefShare, and local bereavement groups offer compassionate resources. If you or someone you know is struggling with intense grief, please reach out to mental health professionals who can help navigate these deep waters.
When grief comes crashing like the ocean, remember these words—and hang on. There is life between the waves.
