Not sure if this topic belongs here, but I thought it would make an interesting one. I also did not find it under search.
Star jelly, or pwdre sêr, is a compound purportedly deposited on the earth during meteor showers. It is described as a foul-smelling, gelatinous substance, which tends to evaporate shortly after having fallen.
There have been reports of pwdre sêr (Welsh for rot of the stars) for centuries. A long article in the paranormal magazine Fate declared Star Jelly to be of extraterrestrial origin, calling it "cellular organic matter" which exists as "prestellar molecular clouds" which float through space.
There have been connections made between Star Jelly and unidentified flying objects — some UFO watchers believe that UFOs are not alien constructs, but living beings called atmospheric beasts, and that the Star Jelly is their remains once they fall to earth.
Many skeptics feel that Star Jelly is probably a naturally occurring material such as slime molds, nostoc, or lichen, and that the extraterrestrial connection occurs when people see meteor showers, rush to where they think the meteors fell, and find the already-existing mold on the ground.
Godfrey Louis is a solid-state physicist currently studying "blood-colored showers" that fell in 2001 near his home in Kerala in India. He thinks they may come from space. He has isolated red 10-micrometre structures that may reproduce without DNA, but have not been extensively tested. [4]
Little scientific analysis has been done on Star Jelly. The Guardian Unlimited reported in January of 2005 that Welsh naturalist Thomas Pennant, writing in the 18th century, believed the material to be "something" vomited up by birds or animals.
More recent scientific speculation has pointed towards frog spawn which has been vomited up by amphibian-eating creatures (notably European Polecats), though no frog spawn has ever approached the size of some reported cases of Star Jelly. The German terms Sternenrotz (star snot) and Meteorgallerte (meteorite jelly) are known to refer to more or less digested frog spawn vomited by predators (Schlüpmann 2007). This is quite easy to identify by its smell and found in winter and early spring near frog spawning sites (see below for images).
The Massachusetts Department of Environment Quality Engineering examined the "star fall" which dropped on North Reading, but the only results were that the material was "non-toxic."
