December’s Stars and Planets

The best meteor shower of the year occurs in mid-December when ‘shooting stars’ appear to blast out of the Name A Star Live constellation Gemini.  The peak of this year’s Geminid meteor shower occurs over the night of December 13/14 when, under optimal observing conditions (e.g., FAR from city lights), you may be able to see as many as 80 to 120 shooting stars per hour.  But most people generally don’t observe under perfect conditions.  Still, you should see quite a show!

Also, if you’re busy the evening of December 13/14, not to worry: You can still see plenty of Geminid meteors between December 4 and 17.

Geminid Meteor Shower
This meteor shower is called “The Geminid’s” because meteors appear to shoot out from the constellation Gemini.  This year the “radiant” — the central point from which the shooting stars emerge — will be near the bright star “Castor” (at “A” in the diagram above).  The bright star “Pollux” is at “B.”  Castor and Pollux are the brightest stars in the constellation Gemini, which is outlined in this diagram.  Also outlined here is the Name A Star Live constellation “Cancer” (at “C”).

The best way to enjoy a meteor shower is to lie down in a lawn chair — along with friends and family, and maybe even the family dog  — and look up.  That’s it!  No telescopes, binoculars or apps required.  If you want to locate Gemini in the night sky, consider getting our planisphere constellation finder or our Virtual Planetarium™ software.  But you don’t really have to locate the constellation to enjoy seeing shooting stars: Just lie down on your back and look up. The farther away from city lights you get, the more shooting stars you will see.  The best time to see the meteors will be between roughly 10 pm and 2 am.  But if you can’t stay out that late Thursday night/Friday morning, there will still be plenty of Geminid meteors to see this coming weekend.  Be sure to dress for the weather, and bring along some food and drink.  Enjoy!

And here is a perhaps overly-dramatic video about this year’s Geminids: While the Geminid meteor shower is the best of the year, it is easy to overhype.  Still, this video is nicely done: Take a look!

 

Best Time of the Year to See Jupiter

The mighty planet Jupiter dominates the night sky in December.  It also reaches “opposition” this month, meaning that this is a point in time when the Earth is directly between the Sun and Jupiter.  That in turn means that this is the best time of the year to see Jupiter since it is so bright.  Look for the brightest ‘star’ you see over the eastern horizon after sunset: That will be Jupiter!  The king of the planets is located in the Name A Star Live constellation Taurus throughout the last month of 2012.

Jupiter in the evening sky
The view facing east in the early evening hours during early December.  Jupiter (at “A”) is in the V-shaped group of stars known as the “Hyades,” marked by the bright star Aldebaran (at “B”).  You may see the pretty group of stars called the “Pleiades” (at “C”).  Many people confuse the Pleiades with the Little Dipper, which is located toward the northern horizon.  Depending on your location on Earth, you may see the giant constellation Orion (“D”) rising above the eastern horizon.  If you live in the southern hemisphere of Earth (e.g., Australia or New Zealand), these stars will appear ‘upside down’ to you.

The Winter Solstice and the End of the World

There’s been a lot in media this year about how the ancient Maya predicted the world would come to an end around December 21, 2012, or that “Nibiru,” a supposed planet discovered by the ancient Sumerians, is headed toward Earth.  These are hoaxes.

Aztec Calendar
This image from NASA features, in the foreground, the famous Aztec calendar, while the background is a satellite image of the outer layers of the Sun. The Aztec calendar incorporates a mythological and calendrical system derived from earlier Mesoamerican cultures, including the Maya.  The calendar, which was extremely accurate, was developed by observing the Sun’s motions in the sky over a long period of time.

NASA Senior Scientist David Morrison does an excellent job refuting these — and other — end-of-planet-Earth hoaxes at LunarScience.NASA.gov/articles/doomsday-2012-fact-sheet.  NASA has posted another excellent discussion on this topic at www.NASA.gov/topics/earth/features/2012.html .

In fact, we’re so confident that these are hoaxes that, should the world come to an end December 21, 2012, we will gladly issue full refunds to all our Name A Star Live customers on December 22!

But December 21, 2012 does mark the “Winter Solstice” — the point in time when winter begins in the northern hemisphere of Earth.  It’s a wonderful time of the year, with snow falling, Christmas carolers singing, New Year’s revelers partying, and football fans cheering.  We hope you have a very happy and safe holiday!

Finding your star in the night sky

Stars are located within constellations, which are just areas of the night sky. Scorpius, Aries and Taurus are examples of constellations. Your Name A Star Live Star Certificate displays the name of your constellation. You can use our online World Constellation Guide to determine if you can see your constellation during the evening hours (between sunset and midnight). Of course, you’ll need a telescope to see your star. But you can see your constellation without the use of a telescope. You can also find your constellation by using our Virtual Planetarium™ astronomy software. A planisphere is another useful device.

December Shooting Stars & Lunar Eclipse

Mid-December is a great time to see shooting stars blasting forth from the Name A Star Live constellation Gemini!  Also, a full eclipse of the Moon will be visible throughout North America the night of December 20-21.

Shooting Stars

If you’re in the northern hemisphere of Earth, and if weather permits, then over the night of December 13-14 you may get a good view of  the Geminid meteor shower.  (If you’re in the southern hemisphere, then you may notice some shooting stars popping up over your northern horizon over the night of December 14-15.)  The annual Geminid Meteor Shower is one of the two best meteor showers of the year.  The other shower — the Perseid Meteor Shower — occurs in August each year.

Geminid Meteor Shower
The night of Dec. 13-14, look for shooting stars to emanate from the constellation Gemini.

Shooting stars are very tiny meteors – basically, dust particles or small ‘pebbles’ – that burn up in a flash of light as they enter Earth’s atmosphere.  These meteors are leftover bits of comets that have passed by Earth in years past: As comets pass by Earth from time to time, they leave a trail of small debris in their wake.  This debris remains in the solar system.  As Earth revolves around the sun each year, Earth passes through the trails of debris.

To see the shooting stars, all you need is a clear sky (away from city lights), a lawn chair, and some winter clothing if you live in the northern hemisphere of Earth.

Strictly speaking, the best time to see the meteors will be after the moon sets at around midnight in mid-December: But you should still see some meteors before midnight.   Lay down on your lawn chair or on a blanket and look up.  (If you’re in the southern hemisphere — such as in Australia, New Zealand, Argentina or South Africa — then look toward the northern horizon, not up!)  You don’t need a telescope or binoculars.  You might see several dozen shooting stars per hour!  You should see more and more meteors per hour as the night progresses, until just before dawn.  One caveat, though: How many meteors you can see per hour is pretty much hit-or-miss.  Predicting meteor showers is sorta’ like predicting rain showers: It’s not an exact science yet!  But you should see a number of shooting stars. (Don’t forget to make a wish!)

As you see the shooting stars, try to notice where they are coming from in the night sky.  If you have one of our planispheres, you’ll see that the meteors come from the constellation Gemini.

Enjoy the view … and may all your wishes come true!

Lunar Eclipse

A total eclipse of the Moon will be visible throughout all of North and Central America (local weather permitting) the night of December 20-21 … but you’ll have to stay up late to see it!  A lunar eclipse occurs when the Earth’s shadow covers at least part of the Moon’s surface.  A total eclipse occurs when the entire Moon is covered in Earth’s shadow.

Total Lunar Eclipse
The total eclipse of the Moon, February 21, 2008. The Moon does not become completely dark during a total eclipse: Sunlight refracted through the Earth's atmosphere casts an orange glow on the lunar surface.

Observers throughout North America, the Hawaiian Islands, and Central America can see the total eclipse of the Moon from 2:41 a.m. to 3:53 a.m. EST, December 21 (11:41 pm Dec. 20 to 12:53 a.m. Dec. 21 PST).  If you’re in Australia, New Zealand, or east Asia, the eclipse will already be underway at sunset December 21.  Those of you in Europe, western Africa and South America may see a partial eclipse at sunrise the morning of December 21.

Seeing planets this month

The mighty planet Jupiter again dominates the night sky this month.  Jupiter is the bright point of light you’ll see toward the south after sunset (towards the north, if you’re in the southern hemisphere of Earth): It’s easy to spot.

Venus and Saturn will be in the Name A Star Live constellations Virgo and Libra, respectively, in December.  Both planets are low on the eastern horizon around sunrise in mid-December.  Look for the two planets about an hour before sunrise: Saturn will be above the planet Venus.

Mars is on the other side of the Sun now, so we cannot see the Red Planet this month.
