so when and where can you see solar eclipses? Tintin Knows

this was such a mind boggling map

you would have expected the eclipse to be visible on so much more of the Earth's surface, at least I would, but not in this case!

read and wonder.



I am always reminded of Tintin in the Prisoners of the Sun whenever I hear Solar Eclipse, do you remember it?

Tut's comet

Kids

This is such a fascinating story. It weaves astronomy, archaeology, history, Egyptology, and astronomy along with chemistry. 

Comet remains not found anywhere else other than in this piece and that too in king tut's brooch? 

Amazing story
Can you imagine the ancient Egyptians standing and looking up at the comets blazing across the sky and thinking what kind of a message the gods are sending them? 

Love

Brooch of Tutankhamun Holds Evidence of Ancient Comet
Tue, Oct 08, 2013
Even more, scientists confirm first-ever finding of a fragment of the
comet's core.
Most have heard of the treasures of the 18th Dynasty pharaoh
Tutankhamun, first discovered by Howard Carter and Lord Carnarvon in
1922 when they uncovered his tomb in the Valley of the Kings in Egypt.
Few are familiar with his impeccably preserved brooch, recovered along
with the numerous other artifacts within the tomb. Fewer still know
about the striking yellow-brown scarab that is set at its center, and
that it is made of a yellow silica glass stone procured from the sand
of the Sahara and then shaped and polished by ancient craftsmen. The
silica glass was originally formed 28 million years ago, when an
ancient comet entered the earth's atmosphere and exploded over Egypt,
heating up the sand beneath it to a temperature of about 2,000 degrees
Celsius and resulting in the formation of a huge amount of the yellow
silica glass, which lies scattered over a 6,000 square kilometer area
in the Sahara.

Rahu and Ketu in mythological and astronomological contexts

Fascinating paper. Publicly available, go check. And a great set of references tracking the development of Rahu and Ketu as mythological, astronomical and astrological aspects.

Fascinating Astronomical Photograph

Quoting from here:

Explanation: If you took a picture of the Sun at the same time each day, would it remain in the same position? The answer is no, and the shape traced out by the Sun over the course of a year is called an analemma. The Sun's apparent shift is caused by the Earth's motion around the Sun when combined with the tilt of the Earth's rotation axis. The Sun will appear at its highest point of the analemma during summer and at its lowest during winter. Today, the Winter Solstice day in Earth's northern hemisphere, the Sun is at the bottom of the analemma. Analemmas created from different latitudes would appear at least slightly different, as well as analemmas created at a different time each day. This particular analemma was built up by 46 separate Sun photographs taken during 2003 in Athens, Greece.

Looks almost like its a paddle for the women on the patio... :)
