Although the ring dust is very cold -- minus 316 degrees Fahrenheit -- it shines with thermal radiation.
No one had looked at its location with an infrared instrument until now, Clavin said.
The bulk of the ring material starts about 3.7 million miles from the planet and extends outward about another 7.4 million miles.
The newly found ring is so huge it would take 1 billion Earths to fill it, JPL said.
1 billion earths -- that's a lot! Not as many as you could fit in my stomach, but I've been expanding it with balloons. I'm gonna be a drug mule!
