What if I told you the Sun has been hiding explosive secrets that scientists couldn't figure out for 70 years?

The Day NASA's IRIS Saw the Sun's Secret Dances!

A tiny spacecraft reveals the Sun's wild, explosive mysteries

NASA's tiny IRIS spacecraft discovered secret explosions that make the Sun's atmosphere super hot!

On October 13, 2014, NASA scientists got super exciting news! Their newest solar telescope called IRIS (which stands for Interface Region Imaging Spectrograph) had been watching the Sun for over a year, and it finally solved some HUGE mysteries about our favorite star!

Here's the thing about the Sun that puzzled scientists for decades: The Sun's surface is about 10,000 degrees Fahrenheit. But weirdly, the area ABOVE the surface (called the corona) is millions of degrees hotter! That's like walking away from a campfire and somehow getting MORE burned. It made no sense!

But IRIS, which is only about as big as a large refrigerator, discovered something amazing. It spotted tiny jets of superhot gas shooting up from the Sun's surface like millions of mini-rockets! These jets are called "spicules" and they zoom up at 150,000 miles per hour. That's fast enough to travel from Earth to the Moon in about 90 minutes!

IRIS also found hidden "bombs" of energy exploding in the Sun's atmosphere, releasing heat that warms up everything around them. It's like finding out the Sun has secret fireworks going off all the time!

💡 IRIS takes a new picture of the Sun every 5 to 10 seconds, capturing details smaller than the state of Colorado!
