- Racehorse Falls (waterfallsnorthwest.com)
Racehorse Creek thunders over a great waterfall situated within a short, shallow and very interesting gorge. The falls drop a total of 139 feet over four distinct steps. The first two tiers are back-to-back punchbowl-type plunges of 19 and 44 feet respectively, which both feature deep potholes at their bases. Immediately below the second tier the creek accelerates down a ramp-like cascading fall for about 15 feet and then comes to the final drop where it first plunges over an undercut ledge and then slams onto a diagonally pitched bedrock ramp and veils out in a broad sheet, with a small pool on one side about three-quarters of the way down and ending in a much larger pool. The basin at the bottom of the falls is held back by a second diagonally pitched ramp of bedrock, within which is another small fall of about 10 feet.
- Stingray Nebula (Wikipedia)
The Stingray Nebula (Hen 3-1357) is the youngest-known planetary nebula, having appeared in the 1980s. The nebula is located in the direction of the southern constellation Ara (the Altar), and is located 18,000 light-years (5,600 parsecs) away. Although it is some 130 times the size of the Solar System, the Stingray Nebula is only about one tenth the size of most other known planetary nebulae. The central star of the nebula is the fast-evolving star SAO 244567. Until the early 1970s, it was observed on Earth as a preplanetary nebula in which the gas had not yet become hot and ionized.
