"

Four decades after their discovery, the 13 mysterious rings around Uranus surprised astronomers again this summer.

In June, new images captured their warm glow for the first time. Well, warm for Uranus.

At -320 degrees Fahrenheit, the rings are 10 degrees warmer than the planet's surface, which is the coldest in our solar system. Scientists determined the rings' temperature thanks to these thermal images."

Astronomy is fascinating..... I know little...the pictures portray science concepts learned long ago.

My cell phone....a technologic advance not dreamt of in my college years in the 1970s can even image Jupiter in the summer sky....just above the horizon.

@meepmeepmayerI decided to try using a telescope eyepiece to cell phone adapter (Meade product) to improve my through the eyepiece photography with my ETX90. (Moon & planets like Saturn and Jupiter)

The FedEx tracking says it's in my state and on it's way.
