Earth to be hit with ISON meteor shower, scientists to study particles of dust

From January 15-16 a stream of cosmic dust - the remains of the tail of the recently disintegrated comet ISON - will hit the Earth. If the particles are large enough, Earth dwellers will see a "meteor shower." However, another phenomenon is more likely - noctilucent clouds. Scientists will try to collect particles of dust, which will fall to the Earth: possibly containing the oldest Solar System material, perhaps, even with blocks of organic matter.
At
the end of November, ISON came to its one and only fatal date with our
Sun. It was born in the Oort cloud – a giant sphere consisting of ice
blocks surrounding the Solar System. Long ago when there were not even
bacteria on the young Earth, ISON began its slow fall to the Sun,
gradually accelerating. Its substance bears an untouched imprint of the
interstellar medium. And there will be a chase after it on the Earth,
head of the CryoAstrobiology laboratory of the St. Petersburg Nuclear
Physics Institute Sergey Bulat explains.
"When
the comet was heading to the Sun, it already possessed a train of gas
and dust. Now, in mid-January, the Earth is included in this train,
which existed before its approach to the Sun. Our task is to gather the
remains of this dust, which were not exposed to heating. It is 4 billion
years old. The emphasis is made on small dust particles, whose size is
no more than a few microns. The reason: while entering the Earth's
atmosphere even at high speeds, these particles do not warm up to such a
degree that makes all organic matter, which might be included in them,
evaporate," he said.The
collection of dust particles will be carried out three times until the
end of January by members of the Russian expedition in the Antarctic,
the cleanest place on Earth. The frozen material will be delivered from
the Vostok station to the laboratory and examined under an electron
microscope, Sergey Bulat says."The
main thing is a focus on carbon compounds. Maybe there are blocks of
life, nucleotides or amino acids. If we arrange these particles
correctly, then we can answer the question: Were there some blocks of
life at the moment of the Earth’s formation or not?" Bulat said. Melted
down by the heat of the Sun, the comet was completely ruined. Its
remains would have also been of interest to the science. Unfortunately,
they will not intersect with the Earth, head of the Department of
Physics and Evolution of Stars of the Institute of Astronomy of the RAS Dmitry Wiebe says."In
December, the Hubble telescope was looking for a cloud of fragments
left by the comet after its flight near the Sun. It is very far from the
Earth, and a collision with it is not dangerous for us: we will not be
in this area of space. All we can see are particles that the comet lost
just before its rendezvous with the Sun," he said. However,
the scientist doubts that the particles of dust from the comet's tail
will fall in Antarctica before the end of January.
"Fine
dust will slow down in the atmosphere and will very slowly fall down
together with the rest of the cosmic dust, which the Earth gathers
during its motion. Will it be possible to confidently link these
particles to comet ISON? Even if we find these particles and determine
their chemical composition, it will be difficult to link them to a
particular celestial body," Dmitry Wiebe said.According
to the earthsky.org Internet portal, the smallest particles of the
comet can wander in the air flows for up to several months, causing a
beautiful phenomenon - noctilucent clouds. And most likely, there will
be no "meteor shower."However,
comets are poorly explored and unpredictable objects, thus, any
surprises are possible. And ISON has already sprung one of them: the
forecast, according to which it was to become one of the brightest
comets of the century and even to overshadow the full Moon, did not come
true. This would have happened if the celestial body had not
disintegrated prematurely.Boris Pavlischev
