No, comet 67p/Churyumov-Gerasimenko is not about to explode or disintegrate. But as it steadily gets nearer to the Sun the comet’s jets are getting more and more active and they’re putting on quite a show for the orbiting Rosetta spacecraft!

A Shubunkin is a type of single-tailed goldfish with calico coloration, a combination of orange, white, black, red, and blue markings, blue being the most desired. They are similar to the common goldfish and the comet goldfish. Also called speckled goldfish, harlequin goldfish, calico goldfish, and coronation fish, they were developed in Japan about a hundred years ago by crossing calico fantails with single-tailed goldfish to produce a hardy, able swimmer with bright colors. There are...

A Fantail goldfish is a standard "fancy" type of goldfish. It has a dual-lobed tail, unlike its cousin the common or comet. Its fins can be different sizes, ranging from 1-3 in or more in length. A typical fantail has paired fins, including anal fins, a single dorsal fin, and a round, pointed body shape. It can range in color, from bronze (known as chocolate), orange, red, calico, and mixes of the colors. It is the third hardiest of the fancy goldfish with Comet first and Shubunkin second,...

The Comet is a commonly kept form of goldfish, the only type to have originated in the United States. They first appeared in the ponds of the Fish Commission in Washington in the early 1880s. Hugo Mullertt was the first person to bring the Comet goldfish to the market in a large quantity. Characterized by a long, tall, flowing tailfin they can be differentiated from the common goldfish, although otherwise they are very similar. Both of these varieties are quite hardy and will do well in...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
