Problems with various theories could be resolved if mistaken identity were considered.
It has been demonstrated over the centuries that the worst possible witnesses in court are often those who were present at the scene of the crime. There are documented cases of people being held for crimes they did not commit because one or more eyewitnesses swore to their guilt under oath. It becomes known only later when overwhelming evidence, such as DNA, proves that the alleged perpetrator could not have done what was claimed.
Often, the problem with mistaken identity is one of prejudice. Suspects are categorized by their racial profiles, their affiliations with radical groups, previous behavior, or association with those who are known lawbreakers. Lacking a confession from some other individual, law enforcement personnel are sometimes unable to prevent themselves from focussing on guilt by association, or circumstantial evidence. Assistant District Attorneys do not last long without convictions.
Similarly, professors at prestigious universities are compelled to follow “party lines” and to be prolific in their output of published articles. In order for fundin

ress release from the European Southern Observatory has been corrected to reflect the discovery that 99.99% of the universe is composed of plasma.
This dramatic new image of
cosmic clouds a plasma discharge
in the constellation of Orion reveals what seems to be a fiery ribbon in the sky. This orange glow represents faint light coming from grains of cold interstellar dust, at wavelengths too long for human eyes to see. It was observed by the ESO-operated Atacama Pathfinder Experiment (APEX) in Chile.
Clouds of gas and interstellarPlasma in a gaseous state along with charged
dust and the galactic-scale electric currents that shape them
are the raw materials from which stars stellar plasmoids
are made. But these tiny dust grains block our view of what lies within and behind the clouds dusty plasma
— at least at visible wavelengths — making it difficult to observe the processes of star formation stellar discharge
This is why astronomers need to use instruments that are able to see at other wavelengths of light. At submillimetre wavelengths, rather than blocking light, the dust grains shine due to their temperatures of being heated to
a few tens of degrees above absolute zero from their slight resistance to the galactic current
. The APEX telescope with its submillimetre-wavelength camera LABOCA, located at an altitude of 5000 metres above sea level on the Chajnantor Plateau in the Chilean Andes, is the ideal tool for this kind of observation.
This spectacular new picture shows just a part of a bigger complex called the Orion Molecular Cloud, in the constellation of Orion (The Hunter). A rich melting pot of bright nebulae, hot young stars stellar plasmoids

NOCTILUCENT CLOUDS INTENSIFY:
The "noctilucent daisy
" continues to expand and intensify as summer unfolds. Observers in central-to-northern Europe are reporting vivid, nightly displays of NLCs. Just hours ago, Alan Tough photographed these over Lossiemouth, Moray, Scotland:
"This was another spectacular display of noctilucent clouds," says Tough. "I arrived in Lossiemouth in time to see the Moon rising and managed to capture its glitter path on the River Lossie."
2013 is shaping up to be a good year for NLCs
. The clouds surprised researchers
by appearing early this year, and many bright displays have already been recorded. Once confined to the Arctic, NLCs have been sighted in recent years as far south as Utah, Colorado, and Nebraska. They might spread even farther south in 2013.
Observing tips: Look west 30 to 60 minutes after sunset when the sun has dipped 6o to 16o below the horizon
. If you see luminous blue-white tendrils spreading across the sky, you've probably spotted a noctilucent cloud.
