Last night's eclipse pic and this week's astronomy hi-lights
Five constellations that form part of the same story spread across the
evening. Andromeda, Cassiopeia, Cepheus, Cetus, and Perseus all climb up the
eastern side of the sky, telling a story of vanity, sacrifice, and heroism.
September 29: Mirach
The binary system known as Mirach forms the second-brightest star in the
constellation Andromeda, which is in the east and northeast as night falls.
The system's main star is almost 100 times wider than the Sun, and 2,000
September 30: Chasing Dogs
Two "dog stars" chase across autumn's pre-dawn sky. The brighter one is
Sirius, in Canis Major, the big dog. The other is Procyon, of Canis Minor,
the little dog. Both are high in the sky at first light, with Procyon far to
the upper left of Sirius.
October 1: Early Winter
Autumn is just underway, but you can get a preview of the winter sky in the
hours before dawn. Taurus, the bull, is high overhead, to the upper left of
the Moon. Orion is due south, with Sirius, the sky's brightest star, in the
October 2: The Plow
Ursa Major hunkers low in the north on autumn evenings. Americans see its
brightest stars as the Big Dipper. In England, though, these stars are seen
as a plow. October is a good time to visualize a plow because it stands just
above the horizon.
October 3: Rare Gems
Aquarius, the water-bearer, is in the southeast as darkness falls and stands
highest in the sky, due south, around 11 p.m. Its brightest stars, Alpha and
Beta Aquarii, look fairly faint. In reality, both are brilliant supergiants
that are dulled only by their great distance of 500 light-years.
October 4: Last-Quarter Moon
The Moon is at its last-quarter phase at 4:06 p.m. CDT, so sunlight
illuminates half of the lunar hemisphere that faces Earth. The illuminated
portion of that hemisphere will grow smaller each day until the Moon is new
on October 12.
