NASA'S PICTURE FOR THIS DAY

“HH-222: The Waterfall Nebula” is copyrighted by Mike Selby. NASA has permission to show it and we don't, so it isn't on this card.

COSMIC MESSAGE

The Waterfall Nebula, officially Herbig-Haro 222, stretches about ten light-years in the Orion Molecular Cloud. Its origin is still under investigation, but it appears to be a gigantic gaseous bow shock. This is similar to a wave created by a fast-moving ship, suggesting a powerful, unseen source driving the gas.
