New Feature Article:
SIRIUS MATTERS: Fiction and Facts
Chandraís observation of the white dwarf Sirius B reminds us
that for time out of mind, Sirius, the brightest star in the sky,
has played a prominent, and sometimes peculiar role in mythology and
astronomy. In ancient Egypt, Siriusí hieroglyph, the dog, appeared on
monuments and temple walls dating back beyond 3,000
BC. The rising of Sirius just before the sun on the summer
solstice signaled the beginning of summer, and
coincidentally, the coming flooding of the Nile, an event
critical for supplying the water necessary for agriculture. The
temple of Isis-Hathor at Denderah and numerous other temples in the
Nile valley were oriented to the rising of Sirius.
