Get ready for next week’s total lunar eclipse, one of the most thrilling spectacles that nature has to offer. Find out why eclipses happen and how to view them.
The waxing crescent Moon passes through the Hyades cluster on Thursday. If you watch long enough, you may see the Moon’s dark edge blot out one or more stars.
People living along a narrow path from New York City to Ontario can watch an asteroid blot out the bright star Regulus around 2 a.m. on Thursday, March 20th.
The waning crescent Moon pairs spectacularly Venus in the predawn sky. And many stargazers will try to view all 110 objects cataloged by the 18th-century astronomer Charles Messier.
Three planets are on display in the predawn sky: dazzling Venus low in the southeast, rapidly brightening Mars in Virgo, and Saturn, the ringed wonder, in Libra.
Jupiter, the largest planet in our solar system, flies almost overhead on March evenings. It’s an amazingly dynamic world, and a treat to view through a telescope.

The Great Orion Nebula is the most active star-forming region in our sector of the Milky Way Galaxy. It’s a breath-taking sight when viewed through a telescope.
Mighty Orion, the brightest constellation, flies high in the early evening sky. And late on Wednesday evening, the planet Mars and the bright star Spica float above the Moon.
The Moon is full on Friday, to the right of the bright star Regulus in Leo. The crater Tycho and its amazing ray system are especially bright at full Moon.
The magnificent constellation Canis Major, the Big Dog, is at its highest in the south on February evenings. It is host to Sirius, the brightest star in the night sky.
Mercury and Venus, the innermost planets, are visible all week at dusk and dawn, respectively. The thin crescent Moon visits Venus early in the week and Mercury late in the week.
The Moon visits Mars and Saturn in the predawn sky this week. This is an exciting time to view both planets. Mars is brightening rapidly, and Saturn’s rings are on great display.
This is a great time to view Jupiter, the king of the planets. It’s well up in the east by the time the sky grows dark, and very high by late evening.
Orion floats high in the south on January evenings. Its seven main stars form a pattern that has been likened to a giant man or woman all around the world.
At the stroke of midnight on New Year’s Eve, Sirius, the brightest star in the night sky, is at its highest in the south. And even brighter Jupiter flies high above it.
More bright stars are visible now than at any other time of year. Seven of the sky’s 21 first-magnitude stars are concentrated in a single, amazing formation called the Winter Hexagon.
The December solstice occurs in the early afternoon on Saturday, the shortest day of 2013. After this, days will be getting longer and nights shorter for the next six months.
The Geminid meteor shower peaks on Friday night and Saturday morning. The Geminids are caused by a mystery object that seems to be halfway between an asteroid and a comet.
Comet ISON will reappear this week if it survives its encounter with the Sun. And the Andromeda Galaxy, the nearest big spiral galaxy to our own, soars high in the evening.
Mercury and Saturn appear amazingly close together in the predawn sky early in the week. And Comet ISON skims just 700 thousand miles above the Sun’s surface on Thanksgiving Day.
Mercury, the innermost planet, appears in the predawn sky as Comet ISON races toward its rendezvous with the Sun. And Saturn, the ringed wonder, joins the action late in the week.
If we’re lucky, Comet ISON will become faintly visible in the predawn sky this week. But comets are notoriously unpredictable, so nobody can say for sure what will happen.
The ancient constellations of the Great Sea fill the southern sky, from Cetus the Sea Monster to strange Capricornus the Sea Goat, whose origin is lost in the mists of time.
Look to the right of Cassiopeia for a formation that I call the Really Big Dipper. It’s composed of the three brightest stars of Andromeda together with the Great Square of Pegasus.
