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.
