The Little Dipper - 23JAN2009

January 23, 2009

The Little Dipper stands in the north tonight and every night. The star at the tip of its handle is Polaris, the north star, which appears in the same position in the sky every night. The other stars of the Little Dipper rotate around Polaris, and never set.

January 22, 2009

The panoply of constellations includes one king: Cepheus, the mythological king of ancient Ethiopia. His constellation looks like a child's drawing of a house, with a rectangle of stars topped by a pointed roof. It is high in the northwest in early evening.

The Milky Way - 19JAN2009

January 19, 2009

The Milky Way arcs high overhead this evening. It forms a hazy, glowing band of light, like a subtle cloud. It is the combined glow of millions of stars in the disk of the Milky Way galaxy. But it's visible only from dark viewing locations, away from city lights.

Eye Of Taurus - 18JAN2009

January 18, 2009

The baleful eye of Taurus, the bull, stares unblinking from high in the sky tonight. Orange Aldebaran is one of the brightest stars in the night sky, and one that gives us a glimpse of the fate of our own star, the Sun.

Taurus The Bull Constellation Tonite - 17JAN2009

January 17, 2009

Taurus, the bull, charges high across the south on winter nights. Thanks to three "landmarks," he's one of the easiest constellations to find. The landmarks are his bright orange "eye," the star Aldebaran; his V-shaped face; and the Pleiades cluster on his shoulder.

Betelgeuse and The Winter Circle - 16JAN2009

January 16, 2009

The Winter Circle blazes forth tonight. It is in good view by around nightfall, and wheels across the south during the night. It is so big that it fills almost an entire quadrant of the sky. Its hub is Betelgeuse, the orange "shoulder" of Orion

Winter Skies Are Summer Nights - 15JAN2009

January 15, 2009

If you long for warm nights under the stars, recall the summer sky about an hour before sunrise tonight. The stars that appear during early evening in summer also appear just before dawn in winter. So tomorrow, you will see the stars as they will look during July.

January 12, 2009

Leo's brightest star, Regulus, is a little below the Moon as they rise in mid evening. The rest of Leo spreads out below and to the left of Regulus, which is at the tip of a pattern of stars that looks like a backwards question mark, known as the Sickle.

January 10, 2009

The two brightest stars in the night sky scoot across the south late tonight. Sirius stands high in the sky in late evening. Canopus is far below Sirius, though you have to be at the latitude of Dallas or points southward to see it.

The Big Dipper Tonite - 08JAN2009

January 8, 2009

Look toward the northeast during late evening for the Big Dipper. The handle points toward the horizon, with the bowl high in the sky. The second star from the end of the handle is called Mizar. If you look carefully, you might see its faint companion, Alcor.

Sirius "The Dog Star" - 07JAN2009

January 7, 2009

Sirius, the brightest star in the night sky, rises in the southeast in early evening and climbs across the south during the night. It looks so bright in part because it is one of our closest stellar neighbors, at a distance of just 8.6 light-years.

Polaris (The North Star) Stays Steady-05JAN2009

January 5, 2009

Polaris, the north star, marks Earth's northern axis on the dome of the sky. As Earth turns, all the stars appear to move across the sky except Polaris. As though forming the hub of a wheel, Polaris stands still while the other northern stars circle around it.

Perihelion Today: Earth's Orbit Closest To Sun

Mercury Shows Up Starting Tonite - 03JAN2009

January 3, 2009 The planet Mercury puts in a meek appearance the next few nights. Look for it beginning about 30 minutes after sunset. It looks like a moderately bright star, but you will need a clear southwestern horizon to spot it, and binoculars will enhance the view. This image shows Mercury down and to the right of the Moon as a very faint-looking star.

The Quadrantid Meteor Shower - 02JAN2009

January 2, 2009
The Quadrantid meteor shower is at its best tonight. It is named for the extinct constellation Quadrans Muralis, which represented an astronomical instrument. The shower is fairly reliable, so during its short peak, you may see a few dozen "shooting stars" per hour.
