IC 443 (also known as the Jellyfish Nebula and Sharpless 248 ) is a galactic supernova remnant (SNR) in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth. IC 443 may be the remains of a supernova that occurred 30,000 - 35,000 years ago.
Aequorea victoria, also sometimes called the crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America.. The species is best known as the source of aequorin (a photoprotein), and green fluorescent protein (GFP); two proteins involved in bioluminescence.
A jellyfish galaxy is a type of galaxy found in galaxy clusters. They are characterised by ram pressure stripping of gas from the affected galaxy by the intracluster medium , triggering starbursts along a tail of gas.
The nebula's color depends on its chemical composition and degree of ionization. Due to the prevalence of hydrogen in interstellar gas, and its relatively low energy of ionization, many emission nebulae appear red due to strong emissions of the Balmer series. If more energy is available, other elements will be ionized, and green and blue ...
Four protein mutations from the wild-type GFP found in Aequorea Victoria jellyfish were needed to create the YFP mutant. The most important mutation was the replacement of threonine with tyrosine at residue position 203 [1] (the substitution is denoted by T203Y, where T and Y represent the single letter code for the amino acids threonine and tyrosine, respectively).
The zodiacal light and gegenschein, which are caused by the diffuse reflection of sunlight from interplanetary dust in the Solar System, are also similar phenomena. The Belt of Venus can be observed as having a vivider pink color during the winter months, as opposed to the summer months, when it appears faded and dim above the yellowish-orange ...
The jellyfish measure about 8 inches (20 centimeters) in length. A rock slab shows one large (right) and one small (left) bell-shaped jellyfish with tentacles. The smaller animal is rotated 180 ...
A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae.
