Explanation: What created the Waterfall Nebula? The origin is still being researched. The structure, officially designated Herbig-Haro 222, appears in the region of NGC 1999 in the Great Orion Molecular Cloud complex. The elongated gaseous stream stretches about ten light years but appears similar to a long waterfall on Earth. Recent observations indicate that HH-222 is likely a gigantic gaseous bow shock, similar to a wave of water caused by a fast-moving ship. The origin of this shock wave is thought to be a jet outflow from the multiple star system V380 Orionis off the lower left of the frame. Therefore, gas does not flow along the waterfall, but rather the entire structure moves toward the upper right. The Waterfall Nebula lies about 1,500 light years away toward the constellation of Orion. The featured image was captured earlier this month from El Sauce Observatory in Chile.

I’m glad that you didn’t forget us today. I was beginning to wonder. :)
It kind of reminds me of the Veil Nebula.
Happy New Year, MC!
At the bottom of the ‘waterfall’ is a bat’s head.
Please add me to your APOD ping list.
And a HAPPY NEW YEAR to you with thanks for taking the time to post these pantastic pictures.
You are added to the APOD list.
His right eye is clear but the left is shaded, long nose with two nostrils, upper lip, mouth open with chin shaded.
And he has a diamond shaped hole in his forehead.
Sorry, I was at my brothers house without my computer.
Happy New Year to all astronomy buffs.
Looks like a monkey by a bath faucet.
Proof that Ozzy was there.
Wow.
Wow.
Cool.
Cool.
I’m often amazed at what observatories find out there. Strange and beautiful sights that are sometimes unexplainable.
GMTA. A smiling bat.
