Dreams of establishing a manned
Moon base could become reality within two decades after India’s first
lunar mission found evidence of large quantities of water on its
Data from Chandrayaan-1 also suggests that water is still being formed
on the Moon. Scientists said the breakthrough — to be announced by Nasa
at a press conference today — would change the face of lunar
mare’s tails are wispy cirrus clouds while . . . mackerel scales are small clumpy altocumulus clouds resembling fish scales in the sky. In the days of large sailing ships,
this meant a storm would be approaching soon and the sails should be
lowered to protect from the accompanying high winds.
A Brocken spectre is an apparently gigantic shadow cast in fog or mist, often surrounded by an aura. According to Wikipedia:
The "spectre" appears when the sun shines from behind a climber who is looking down from a ridge or peak into mist. The light projects
the climber's shadow forward through the mist, often in an odd
triangular shape due to perspective. The apparent magnification of size of the shadow is an optical illusion that occurs when the observer judges his shadow on relatively nearby
clouds to be at the same distance as faraway land objects seen through
gaps in the clouds, or when there are no reference points at all by
which to judge its size. The shadow also falls on water droplets of varying distances from the eye, confusing depth perception. The ghost can appear to move (sometimes quite suddenly) because of the movement of the cloud layer.
This one, which has a decidedly Blair-Witch-Project feel, was taken in Japan somewhere in the Tanzawa region. It's from Wikipedia, and the photographer is unidentified. The Nonist has an article on Brocken spectres today, with a good collection of photos.
In considering future earthquake events, Elnashai noted that there
are two seismic mechanisms that affect the Midwest--the Wabash Valley,
with a calculated capability of a 7.1 magnitude, which will shake the
region about 900 times more violently than the West Salem earthquake in
April 2008, and the New Madrid Zone, which is capable of up to
magnitude 8, which will shake the region more than 2,700 times more
"Under such earthquakes, the ground in some critical
regions will liquefy, as it did in 1811-1812," he added. As with other
disaster scenarios, untold indirect consequences also await populations
in the region. In winter, power--and heat--will be out for weeks, as
well as water and telecommunications. Highways and bridges will be
closed along with rail lines and major metropolitan airports in
Chicago, St. Louis, and Memphis. High-rise buildings in Chicago will
lose windows and other attachments such as TV towers.
