It's Neatorama collaboration Monday!

Yesterday's Astronomy Pic of the Day is today's Neato collaboration.

The last time IotD mentioned Io, it sparked a lot of interest. Io is interesting partly because of the two big zits on it. One is in purple, exploding at the top of the shot; the other is pretty much in the middle, looking like a belly button on the thing.

These are active volcanoes, making Io one of the most remarkable places in the solar system. Tidal forces are causing it to have some sort of internal friction, heating it up and blowing it inside out. Like the heat when you rub your hands together, if you did it really fast, so fast that your flesh melted and came out the edge?

APoD sez the one in the middle has been noticed every time Io has been looked at, the first time being in 1979. It's been an active volcano for at least 18 years.

The hole at the top is spewing stuff out 140 kilometers (86 miles) high.

Cellar IotD has managed to not make any fart jokes during this entry.

Be sure to visit Neatorama for more neato items every day!
