Many people who want to view their star through their own telescope go out and buy a telescope right away, but later find that the expensive telescope they bought doesn’t really suit them. Or they eventually determine that they really didn’t like astronomy as a hobby like they thought they would. Either way, their telescopes end up buried in a closet, basement or attic, and they find that they’ve wasted a lot of their hard-earned money.  Many needlessly burn out on a hobby they might otherwise have enjoyed the rest of their lives if they had only taken a more measured approach in the beginning.

It’s really best to ease into astronomy, learn about the different types of telescopes, try using a few, become an educated consumer, and then make a purchase.  A great way to start is to get the following:

November’s Stars and Planets

The night sky puts on some neat shows this month.  And for those of you in the Land Down Under, you can look forward to an eclipse of the sun!

Shortly before dawn on November 26, Venus and Saturn appear very close together:

Chart showing planets and stars
Saturn and Venus appear to kiss shortly before sunrise on November 26. Go out about 45 minutes before sunrise that morning and face East-Southeast to see these two, bright planets.  If you’re lucky, you might also see the planet Mercury hugging the horizon.  You’ll also see the bright, binary star Spica, located in the Name A Star Live constellation Virgo.

The evening of November 27 also presents a wonderful show:

Star Chart for November 27
Look for the Moon and the planet Jupiter toward the East-Northeast the evening of November 27. Both of these solar system objects will be in the Name A Star Live constellation Taurus. Jupiter will be near the V-shaped group of stars (called “The Hyades”), marked by the star Aldebaran. Look above the Moon for the beautiful group of stars known as “The Pleiades,” which are often confused with The Little Dipper, which is a different group of stars altogether.

Those of you in Australia are in for a real treat this month: An eclipse of the sun!  The sun will be totally eclipsed by the moon along a narrow path across the Northern Territory and Queensland.  But those of you in the rest of Australia will see a partial eclipse (local weather permitting).

Australian map showing eclipse path
Australians will be able to see a solar eclipse the morning of November 14, 2012, weather permitting. A total eclipse of the sun will be visible along the path highlighted in red. A partial eclipse will be visible throughout the remainder of Australia, as well as all of New Zealand.

Never look at the sun directly, even during an eclipse!  For more information about the eclipse, including how to observe it safely, read “Australia counts down to solar eclipse” appearing in Australia’s Cosmos magazine.  Those of you in New Zealand might want to check out the Stardome Observatory’s webpage about the eclipse.  Also, no matter where you live, you can watch the eclipse live, online.

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.

October’s Stars and Planets

Zodiacal Light
Zodiacal Light, a.k.a. “False Dawn”

If you’re an early riser, you’re in astronomical luck in October! While Mars is fading rapidly in the western sky during the early evening hours, Venus and Jupiter dominate the early morning eastern sky.  And if you live in mid to northern latitudes on Earth, you’re in for a special treat: the zodical light, or “false dawn.”

False Dawn

The false dawn looks like a faint, triangular-shaped light that stretches from the eastern horizon up into the sky above.  It appears during the period of time between about 1 to 2 hours before sunrise at about this time of year.  This year, the best time to view this spectacle is between October 13 and 27.  To see it, go far from city lights on a clear, moonless night.

This strange celestial display is caused by the reflection of sunlight off of tiny particles of dust in space.  The dust orbits the sun in the same way Earth does. So at this particular time of the year — when the days and nights are of roughly equal length — we view this dust when it is aligned vertically in our pre-dawn, eastern sky.  A similar thing will happen six months from now, only the triangular shape of light will appear in the western sky, after sunset.

The Planets This Month

Venus is the ‘morning star’ — the bright point of light you’ll see toward the east before sunrise.  Look for the giant planet Jupiter — in the consetllaton Taurus — toward the south, near the prominent constellation Orion, shortly before sunset.  (If you live in the southern hemisphere of Earth, Jupiter will appear toward the north shortly before sunrise.)  Jupiter will also appear as a bright ‘star’ in the night sky.

But fear not, fellow night owls, for you too can feast your eyes on some celestial treats! The planets Neptune and Uranus will be visible through binoculars and small telescopes during the evening hours this month. While you can see both Neptune and Uranus through a telescope, Uranus — strictly speaking — is just barely visible to the naked eye — but just barely! In order to see it, you’d need to go far from city lights and view it on a clear, moonless night. (And you better have good eyesight to boot!) We recommend sticking with your telescope or binocs!

Globular clusters of stars, such as M72, once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Many globular clusters were destroyed over the eons by repeated fateful encounters with each other or the Galactic center. Surviving relics are older than any Earth fossil, older than any other structures in our Galaxy, and limit the universe itself in raw age. There are few, if any, young globular clusters in our Milky Way Galaxy because conditions are not ripe for more to form. Pictured above by the Hubble Space Telescope are about 100,000 of M72’s stars. M72, which spans about 50 light years and lies about 50,000 light years away, can be seen with a small telescope toward the Name A Star Live constellation Aquarius (the Water Bearer).

 

This is the ultimate cute, space video — “A Toy Train in Space” — a story of a father who sends his son’s toy train to the edge of space.

 

This is an absolutely beautiful video called “Purely Pacific Northwest” that features views of the Northern Lights and the Milky Way. View this one after a hard day’s work!

The Dog Days of Summer

Here in the United States, it’s hot. Real hot. Vast areas of the country are experiencing record drought. As the old saying goes, we’re in the midst of the Dog Days of Summer.

You may be surprised to learn that the term “Dog Days of Summer” is based on astronomy. The term dates back to the time of the ancient Egyptians and Romans who associated the first rising of the bright star Sirius — together with the early morning Sun — as marking the onset of very hot weather. In fact, the Romans (falsely) believed the heat from Sirius actually contributed to the hotter weather here on Earth during the summer months. The Egyptians called Sirius “the dog star” (among other names) and also associated its rise with the annual flooding of the Nile river, which was critical to Egyptian agriculture. The Romans, however, saw the Dog Days of Summer as an inauspicious time of year, when disease became rampant in the heat and humidity of summertime Rome.

Sirius is the brightest star in the nighttime sky, and is in the constellation Canis Major, which is Latin for “the large dog.”

The Romans considered the Dog Days of Summer to run from late July through late August. The Greek word ὀπώρα (Opora) appears in the lexicon of the King James Bible, and basically refers to the part of the year between the rising of Sirius and the rising of another star called “Arcturus,” which basically demarcate the period of time we call the Dog Days of Summer.

In folklore, the Dog Days of Summer were perceived as the time of year when dogs went mad with the extreme heat of summer.

Here is a little ditty from folklore about the Dog Days of Summer – a ditty that often appeared in farmers’ almanacs:

Dog days bright and clear
Indicate a happy year;
But when accompanied by rain,
For better times our hopes are vain

The Dog Days even appear in the Charles Dickens’ classic, wintertime tale, A Christmas Carol:

Oh! But he was a tight-fisted hand at the grindstone, Scrooge! a squeezing, wrenching, grasping, scraping, clutching, covetous old sinner! Hard and sharp as flint, from which no steel had ever struck out generous fire; secret, and self-contained, and solitary as an oyster. The cold within him froze his old features, nipped his pointed nose, shrivelled his cheek, stiffened his gait; made his eyes red, his thin lips blue; and spoke out shrewdly in his grating voice. A frosty rime was on his head, and on his eyebrows, and his wiry chin. He carried his own low temperature always about with him; he iced his office in the dog-days; and didn’t thaw it one degree at Christmas.

Here’s a neat image from the Hubble Space Telescope of a beautiful object that can be seen from just about anywhere in the world at this time of the year:

The Pleiades
M45, The Pleiades Star Cluster

Located in the constellation Taurus, the Pleiades Star Cluster (designated “M45” by astronomers) is one of the most famous and beautiful objects in the night sky.  The Pleiades, which can be seen without the aid of a telescope,  are often confused with the Little Dipper due to the arrangement of the Pleiades’ brightest stars in a ladle-like formation.  While, using the naked eye, we can distinguish anywhere from six to nine stars in the Pleiades (depending on local observing conditions and one’s eyesight), in reality M45 has approximately 500 stars located about 400 light-years from Earth.

The Pleiades are also known as “The Seven Sisters” that represent the seven daughters of Atlas and Pleione from classical mythology.  The story goes that when Orion attempted to burst into the private sanctuary of the sisters’ home, Venus turned them into a flock of doves so they could fly away to safety.

The Aborigines also interpreted this group of stars as a cluster of young girls. These girls were seen as musicians who played for a group of boys, which are represented by the stars that are seen in the Belt of  Orion.

The Zuni people of North America called the Pleiadies “seeds” because the first appearance of the Pleiades helped the Zuni decide when to plant their crops. The Zuni also knew that when the Pleiades moved directly overhead in the early morning it was time to harvest what they had planted, because the winter was coming soon.

The Japanese word for this set of stars is “Subaru,” after which the famous Japanese car company is named.  In fact the Subaru corporation’s logo is patterned after M45.

November’s Planets

Jupiter still dominates the evening skies this month: For those of you in the northern hemisphere of Earth, look for the bright, steady light towards the south shortly after sunset.  For those of you in the southern hemisphere, look for Jupiter towards the north shortly after sunset.

You earlybirds in the northern hemisphere will see Mars almost due south (almost due north for those of you in the southern hemisphere) shortly before sunrise this month.  Regardless of where you live, Saturn will be above the eastern horizon before sunrise in November.

Here’s a neat image from NASA of a nearby galaxy in the the constellation Andromeda:

m31
The "Andromeda Galaxy" (M31)

On a clear, moonless night — far from city lights — you can see the Andromeda Galaxy with your naked eye: It will appear as a fuzzy blob of light in the constellation Andromeda.  The Andromeda Galaxy is located relatively close to our own galaxy, the “Milky Way,” at a distance of 2.9 million light years, meaning it takes light from the Andromeda Galaxy almost three million years to reach us.

BTW, we’re on a collision course with the Andromeda Galaxy:  Eventually the Andromeda and Milky Way galaxies will collide.  But don’t worry — the collision won’t occur until billions of years in the future!

Nebulae are clouds of dust and gas.  Many nebulae — like the Trifid Nebula — serve as stellar nurseries, where stars are born.

Be Sure to See Jupiter This Month

This August is a prime time to see the massive planet Jupiter.  It’s at “opposition” in mid-August, meaning the Earth is between the sun and Jupiter, and Jupiter is at its brightest.  Jupiter’s easy to find with the naked eye:

  • If you’re in the northern hemisphere of Earth, Jupiter is the very bright object that you’ll see toward the southeast during the evening hours (between sunset and midnight).
  • If you live in the southern hemisphere of Earth, Jupiter will appear in the northeast during the evening hours.

If you have a telescope, the best time to see Jupiter is in the late evening hours, close to midnight.  At that point Jupiter is high in the sky, above the thicker layers of the atmosphere found near the horizon: You’ll get a much crisper view of Jupiter if you observe it when it’s high in the sky.  You might see as many as four large moons orbiting the planet.

BTW, if your star is in the constellation Capricorn then you’re in luck: Jupiter is also in Capricorn right now.  So just find Jupiter and you’re looking at your constellation.
