SETI Institute scientist and meteor expert Peter Jenniskens reports in a
telegram issued by the International Astronomical Union's Minor Planet Center
(http://www.seti.org/site/pp.asp?c=ktJ2J9MMIsE&b=1233789) that an unexpected
burst of meteors on October 5, 2005 has occurred, which betrayed the presence of
a thusfar unknown, potentially Earth-threatening, comet.

The burst of meteors radiated from a direction on the border of the
constellations Draco and Camelopardalis, and the new shower is called the
October Camelopardalids. The meteors were caused by dust ejected by an
Intermediate Long-Period comet during its previous return to the Sun, and the
detection of the comet's dust trail implies that the comet itself could wander
into Earth's path, if so directed by the gravitational pull of the planets. The
comet itself has not yet been discovered and is likely to return to Earth's
vicinity only once every 200 - 10,000 years. Chances are very small that Earth
will be at the intersection point at the time of the return, hence, there is no
immediate concern. The dust, however, is forensic evidence that may provide more insight into the nature of this new comet when the meteor shower is seen again in the future.

Yep - without clicking the links, I can tell you the names were Regor (Roger spelled backwards, for Roger Chaffee), Navi (Ivan spelled backwards, for Virgil Ivan Grissom) and Dnecos (for Edward H. White II -- i.e., the Second, which Dnecos is, backwards).

Title: Origin and Dynamical Evolution of Comets and their Reservoirs

Authors: Alessandro Morbidelli

Comments: Lectures on comets dynamics and outer solar system formation. 86
pages, 34 figures, 180 references
\\
This text was originally written to accompany a series of lectures that I
gave at the `35th Saas-Fee advanced course' in Switzerland and at the Institute
for Astronomy of the University of Hawaii. It reviews my current understanding
of the dynamics of comets and of the origin and primordial sculpting of their
reservoirs. It starts discussing the structure of the Kuiper belt and the
current dynamics of Kuiper belt objects, including scattered disk objects. Then
it discusses the dynamical evolution of Jupiter family comets from the
trans-Neptunian region, and of long period comets from the Oort cloud. The
formation of the Oort cloud is then reviewed, as well as the primordial
sculpting of the Kuiper belt. Finally, these issues are revisited in the light
of a new model of giant planets evolution that has been developed to explain
the origin of the late heavy bombardment of the terrestrial planets.

Title: The red rain phenomenon of Kerala and its possible extraterrestrial
origin

A red rain phenomenon occurred in Kerala, India starting from 25th July 2001,
in which the rainwater appeared coloured in various localized places that are
spread over a few hundred kilometers in Kerala. Maximum cases were reported
during the first 10 days and isolated cases were found to occur for about 2
months. The striking red colouration of the rainwater was found to be due to
the suspension of microscopic red particles having the appearance of biological
cells. These particles have no similarity with usual desert dust. An estimated
minimum quantity of 50,000 kg of red particles has fallen from the sky through
red rain. An analysis of this strange phenomenon further shows that the
conventional atmospheric transport processes like dust storms etc. cannot
explain this phenomenon. The electron microscopic study of the red particles
shows fine cell structure indicating their biological cell like nature. EDAX
analysis shows that the major elements present in these cell like particles are
carbon and oxygen. Strangely, a test for DNA using Ethidium Bromide dye
fluorescence technique indicates absence of DNA in these cells. In the context
of a suspected link between a meteor airburst event and the red rain, the
possibility for the extraterrestrial origin of these particles from cometary
fragments is discussed.

Mad stuff. Does anyone know of any other research into this? Seems like reasonable research but it needs a bit more work to support the potential extra terrestrial origin claim.
