This photograph of a ship seemingly floating far above the water is not some Photoshop fakery; it's physics creating the illusion. It's an example of what's known as a superior mirage. (Image credit: D. Morris; via The Guardian; submitted by Alec)

What's happening to this cirrus cloud? Ice crystals are acting like little floating prisms. Known informally as a fire rainbow for its flame-like appearance, a circumhorizon arc appears parallel to the horizon. For a circumhorizontal arc to be visible, the Sun must be at least 58 degrees high in a sky where cirrus clouds present below. The numerous, flat, hexagonal ice-crystals that compose the cirrus cloud must be aligned horizontally to properly refract sunlight in a similar manner. Therefore, circumhorizontal arcs are somewhat unusual to see. The featured fire rainbow was photographed earlier this month near West Virginia, USA.

Often researchers are interested in flows around and between objects, but seeing those flows is a challenge in a crowded field of view. One useful trick for this problem is matching the refractive index of your objects and the fluid they're immersed in. (Image credit: Datta Lab, Princeton University, source)

Is it a Yeti sighting or a rare optic phenomenon when a climber at a high altitude can see a distorted refraction of his own shadow cast on a cloud at a lower altitude?
