    LETS TALK ABOUT STARSWhen I was a kid I had a book allabout the stars. Im not sure where it

    came rom or when I got it, but it was

    definitely a grown-up book. Alphas

    and betas, ascensions and declinations,

    complicated star charts - nothing

    ten-year-old me had a chance o

    understanding.

    What it did have, though, were

    myths.Big, ornate drawings o Hercules

    strangling monsters, ancient kings,

    ravenous beasts, and plenty more topique my ten-year-old imagination.

    Tose mythic constellations never

    met up with the stars themselves until

    a ew years into college. I signed up or

    an astronomy class with an identiy

    the stars segment, which everyone

    (naturally) put off until the very last

    week o the all semester. Huddled in

    a reezing parking lot waiting hours to

    be tested, we all ormed a Stockholm

    Syndrome-y admiration or theconstellations.

    Looking back, I didnt know how good

    I had it. I live in Brooklyn now, a magic

    land o tall buildings, light pollution

    and ubiquitous streetlights that limit my

    oand stargazing to a dozen or so stars.

    Despite those challenges, the ones we do

    see are the storied ones.

    A given night will show me the Big

    Dipper, Polaris, Castor and Pollux, the

    Summer riangle and more - easily-identifiable stars and patterns with

    names and stories, stars that add so

    much to the night and yet are so ofen

    overlooked.

    I hope this months Dabbler will

    get you to look up next time youre

    stumbling home afer dark. Whether

    youre in it or the science, the stories, or

    just want to know a little bit more about

    the world around you, hop to it!

    CONSTELLATIONSIn the 2nd century AD, the Roman

    scholar Ptolemy published a work

    called the Almagest, a treatise on all

    things mathematical and astronomical.

    In the seventh and eighth books

    Ptolemy outlined 1022 stars, outlining

    their locations in 48 constellations. Itsthese 48 constellations that orm the

    core o the 88 we have today.

    Hercules, Perseus, Oedipuss lyre -

    Ptolemys constellations were rie with

    Greek and Roman mythology. While

    piecing together stories or the heavens

    had been a practice or the layman

    or thousands o years, the Almagests

    careul cataloging solidified it and

    brought it into the realm o science.

    Ptolemys 48 constellations didntcover the entire sky, though. Spaces

    between constellations were lef empty

    and unnamed, leaving later generations

    o astronomers plenty o space to stake

    their claims.

    In the 16th and 17th centuries,

    astronomy was all the rage. Advances

    in technology and celestial navigation

    made the heavens more important

    than ever, and astronomers rushed to

    include their own additions to the night

    sky in their published charts.

    Exploration o the Southern

    Hemisphere revealed stars the

    Western World had never seen. Dutch

    astronomer Petrus Plancius jumped

    on the chance to claim a ew o hisown and established more than a

    dozen new constellations, o which

    only a ew are still recognized today

    (including Monoceros the unicorn, and

    Camelopardis the giraffe).

    Johannes Hevelius was a Polish

    astronomer who published ten new,

    mostly aint constellations, seven o

    which still grace the sky. He did most

    o his stargazing with the naked eye,

    boasting o his ability to see aint starswithout a telescope.

    Te Wild West couldnt last orever,

    though. In 1928 the newly-ormed

    International Astronomical Union

    codified the sky into the 88 distinct

    constellations that we know today.

    Not enough or you? You might

    want to take a look at the Chinese

    constellation system, which boasts over

    two hundred tiny constellations!

    Sky charts andall the rest

    Once youve graduated rom being

    able to spot the Big Dipper and riends

    youll want to snag a sky chart to track

    down the rest o the celestial crowd.

    Skymaps.com provides the most

    amazing, 100% incredible, andperectly antastic sky charts. All or

    ree! Uncluttered and easy to read, I

    cant recommend them highly enough.

    Folks with smartphones might want

    to check out Pocket Universe(iOS) or

    Google Sky Map(Android).

    While apps are un, I recommend

    starting with paper. Tat little extra

    work goes a long way toward helping

    you remember!

    FOUR-EYED

    MONSTERS

    Bushnell 10x50 Wide Angle

    As powerul as Galileos first telescope! Iown... too many pairs o these.

    $31.99 on Amazon.com

    Bushnell Falcon 7x35

    Not the highest magnification, but theywont require such a steady hand.

    $28.80 on Amazon.com

    Even the absolute worst pair o binoculars can take youto galaxies ar ar away (or at least the moon)

    Te best piece o equipment or thebeginning stargazer isnt a telescope,but a pair o binoculars. Portable,easily adjustable and not nearly as pricy,binoculars do a great job o getting youacquainted with the night sky.

    Why binoculars?In late 1609 Galileo pointed his

    newly-minted telescope at the moon andbegan to tear down thousands o years oknowledge on the celestial sphere. Hisweapon o choice was about as powerulas the worst pair o binoculars you can buytoday, so Im expecting big things out oyou!

    Te biggest advantage o binocularsover a telescope is their field o view, orthe amount you can see at one time. Eventhough you dont get as much magnification

    as you would with a telescope, binocularsallow you to see a larger area at a singletime. Tis makes it much easier to dartrom object to object in the sky, instead ospending time fiddling and arranging andmaking sure youre pointing at juuuuuustthe right spot.

    Beore Galileo, common thought andscientific act held that the Moon andall o the planets were perect spheres,orbiting the Earth in perectly circularorbits. Te moons light and dark spotswere supposedly caused by differences

    in how light was reflected or absorbedrom this perectly flat surace. With alittle magnification, though, its easy to seethat the moon is riddled with ridges andcraters, interspersed with large flat tracts.Old time astronomys loss is your gain,though, so train those binos on our #1satellite and ollow the chart on the nextpage!

    (Yes, you can call binoculars binos.Te world will also accept nocs. Ularsor ullies probably wont fly, but I wontblame you i you give them a shot.)

    One can even spot Jupiters our largestmoons with patience and a steady hand(or a tripod). Ganymede, Callisto, Europaand Io, revealed by nothing more than apair o $30 hand-held binoculars!

    Binoculars are even better i you liveoutside o a city. Previously blank spaces

    yield dozens more stars, and the aintglow o star clusters and other deepsky objects can become part o yournighttime expeditions. Hundreds o theseobjects are cataloged as Messier objects,and you can see them noted on star chartswith an M and a number. With a list o thebrightestand achart o the night skyyoullbe tracking down shiny blobs in no time.

    (But really, check out the Moon! Youvebasically got a handheld spaceship.)

    Binocular sizing

    Binoculars are sized according to twonumbers, or example 7x35 or 10x50.

    Te first number is the magnification,or how much larger an object will appearwhen viewed through the binoculars.While youd think a larger magnification isalways better, theres a trick to it! Once youget to 10x or above, its tough to hold yourbinoculars steady enough to get a good,easy-to-view image. Since a big sellingpoint o binos is portability and ease ouse, stick to 7-10x.

    Te second number is aperture, or how

    large the lens on the ront o the binocularsare. A larger aperture means more lightand a brighter image. Since youre onthe prowl or tiny galaxies ar ar away, alarger aperture and more light-gatheringability is always better or astronomy. Tedownside is size - as the aperture goes up,so does the weight o the bionculars. Youllwant to make sure your first pair is easyenough to tote around and hold steady.

    So what numbers should you be aimingor? Its all personal preerence, but Id

    Canon 10x30 IS Ultra-Compact

    Image stabilization technology + light-weight + large field o view = perect!

    $399.99 on Amazon.com

    recommend a pair o 7x35 binoculars

    Teyre cheap, theyre light, and a greatcompromise between magnification andstability.

    I have a ew pairs o 10x50s, and Imalways a little irritated at how the imagewobbles. I just cant keep my hands steadyenough, and there isnt always a surace toset them on!

    Dont sweat the details, though: nomatter what pair you go with, youll beseeing over 30 times more starsas with theunaided eye. Not bad or a $30 investment

    ChangingseasonsTe Big Dipper travels, butnot too ar rom home.

    a bearby any other nameFun act: Te Big Dipper ainta constellation.

    Id bet good money that i you canonly recognize one constellation in thenight sky, its probably the Big Dipper.Teres one pretty big problem, though:the Big Dipper isnt a constellation!

    Te Big Dipper is what we callan asterism, a pattern o stars thatisnt quite elevated to the level o aconstellation. Te seven stars in theBig Dipper are actually part o a largerconstellation o 20 stars called UrsaMajor, the Great Bear.

    Te blame or the Big Dipper beinga bears butt can be placed squarely onthe Romans.

    Around 150 AD, a Roman scholarnamed Ptolemy published a bookthat outlined the then-48 majorconstellations in the sky. Among those

    In the Northern Hemisphere

    everything in the sky revolves around

    Polaris, the North Star. Due to the

    Earths orbit around the sun, our

    nighttime constellations will be indifferent places (or even disappear!)

    depending on what time o the year it

    is.

    Tis chart shows you the norma

    positions or the Big Dipper in mid-

    evening or the given months. Even i

    its on its side or upside down, the Big

    Dipper is always a perect guide guide

    to the night sky!

    was Ursa Major, swallowing up ourdear riend the Big Dipper.

    Te Almagest - Ptolemys book - isone o the most amous and influentialscientific works o all time, so it isntmuch use arguing now.

    Whether a constellation or not,the Big Dipper has been recognized

    by civilizations across the world. Itsthe Seven Sages in India, a saucepanin Finland, the Northern Dipper inChina, a cart in Hungary and a uneralprocession in Arabia.

    Te Big Dippers smaller sibling theLittle Dipper is in a unique spot - the

    stars o the asterism match up exactlywith the major stars o the constellationUrsa Minor, the Little Bear.

    Orions belt is another well-knownasterism. Oddly, the three stars thatmake it up arent even the brightestin the entirity o Orion - the brightestin the asterism is actually the ourthbrightest in the entire constellation.

    Other, simpler asterisms also dot thesky. Teres the Summer riangle, theNorthern Cross, the Spring riangleand the Winter Hexagon. (Whoevernamed those needs a serious trip to theImagination Factory.)

    Ten, o course, theres the Ice CreamCone. Hiding in the torso o Botesthe of-mispronounced herdsman, theIce Cream Cone is six stars punctuatedwith easily-findable Arcturus, one o

    the brightest stars in the night sky. Nosense o humor? You can stick withcalling it the Kite.

    So next time your riends are oohingand aahing over the Big Dipper, letthem in on the bitter truth: its just thebig bears butt in the sky.

    star lightstar bright

    When the Greek astronomer

    Hipparchus was cataloging stars, he

    needed a system or keeping track o how

    bright they were.

    He decided the brightest were first

    magnitude, the aintest were sixth, and

    distributed the rest in between.

    Weve kept the same system up since

    then, refining it with intricacies like

    negative numbers, decimal points and

    logarithmic math. Te bright star Siriu

    has a magnitude o -1.46, while the

    ainter Caph in Cassiopeia is 2.27.

    Remember, smaller numbers are

    brighter! Once you get to a magnitude

    o 2 or 3 stars are tough to see in cities

    without binoculars or well-adjusted eyes

    In rural areas you should be all set up to

    around 6.

    Tese measurements are also known

    as apparent magnitude, since its the

    brightness as it appears on Earth.

    extinctconstellations

    It began with a bee.

    Finding an unnamed set o stars

    hiding between Aries and Perseus,

    Petrus Plancius popped it on a map in

    1612 and labeled it Apes - the Bee. A

    dozen years later, though, Jakob Bartsch

    swooped in and relabeled it Vespa -

    the Wasp.

    Ostensibly Apes was a little

    too similar to Apus, the Southern

    Hemisphere constellation or the Bird

    o Paradise. Bartsch couldnt rest or

    long, though, because in 1687, Johannes

    Hevelius christened it Musca, the Fly.

    At issue, though, was the act that

    there was already a Fly in the southern

    hemisphere. Musca Borealis, then! Te

    Northern Fly.

    Why each hemisphere needs its own

    fly is lost on me. Astronomy at large

    agreed, and beore long both Musca

    constellations disappeared.

    Another extinct constellation is

    Argo Narvis, the only one o Ptolemys

    original 48 to not make the cut.

    Argo represented the 50-oared boat

    Jason and the Argonauts sailed in

    during their hunt or the golden fleece.

    A huge constellation, it took up around

    5% o the night sky.

    In the late 18th century Nicolas

    Louis de Lacaille split it into 3 pieces- the keel, the stern and the sails - and

    the change stuck. A ew years later part

    o the Argos mast was repurposed into

    Pyxis, the mariners compass.

    Dozens o others got the axe as well,

    rom Cerberus to the lowly Earthworm,

    along with a number o constellations

    dedicated to the astronomers patron

    king, such as Georges Harp and the

    Glory o Frederick.

    STARS MISTAKEN FOR

    PLANETSTe Greek wordplanetes, wandering

    stars, was coined to describe some

    particularly strange stars that seemed to

    move independently o the constellationsWhile the stars are ar enough away

    or their motions to go unnoticed, the

    movement o our Solar System neighbors

    causes them to stumble nonsensically

    across the sky.

    While spotting planets can take

    work, Venus is an easy one. Depending

    on where it is in its orbit, Venus will

    appear either just beore sunrise or just

    afer sunset, always close to the sun. Its

    brighter than any star in the sky (exceptthe sun) so its a tough one to miss!

    7/13

    let there be LIGHT

    Whether youre an amateur in

    a backyard or an astronomer in an

    observatory, light pollution is the

    worst.

    Tere are two ways light pollution

    hurts our ability to stargaze, one

    personal and one environmental.

    Te first deals with our eyes. Te

    back o your eyeball is coated with two

    kinds o cells that help you see - conesand rods.

    Cones do the heavy lifing during

    the day, sorting out colors, helping us

    ocus on detail, and being able to work

    through bright light. While theyre great

    i youre doing your laundry or painting

    a masterpiece, they arent going to help

    much once the sun sets.

    When the light dims, rods start to

    take over. Teyre about 100 times more

    sensitive than cones to light, and willeven respond to a single photon. As

    you might expect, rods are responsible

    or about 99% o nighttime vision.

    Te only problem is that rods take

    a while to warm up.When you leave a

    bright room or the nighttime outdoors,

    it will take up to twenty or thirty

    minutes to get into prime stargazing

    mode. You might eel adjusted afer a

    ew minutes, but remember that a little

    more patience yields many more stars.

    Lights positioned around your

    stargazing area will keep your eyes rom

    ully adjusting to the darkness. Some

    enterprizing astronomers construct

    shields to hold around their heads

    that block nearby light sources, giving

    their rods a better chance to spring into

    action.

    Te second way light pollution getsin the way isjust plain making the sky

    bright. You cant stargaze when the sun

    is out, and i we light up the sky at night

    it works exactly the same way!

    Tis second one is a big problem or

    observatories.Observatories that were

    originally located in rural areas are

    being overrun with urbanization and

    all the light that comes with it.

    Palomar Observatory in southern

    Caliornia is a great example. Teobservatory worked hard to pass laws

    limiting light pollution, but they could

    only do so much. Within the next ten

    years the Palomar will be useless or

    deep-sky astronomy!

    So next time youre griping about

    city lights blocking your view o Orion,

    shed a tear or the multi-million dollar

    telescopes that cant hop a train to the

    countryside.

    S&W Galaxy 6 LED Flashlight

    Help keep your eyes adjusted to the nightwhile checking out your sky charts!

    $23.00 on Amazon.com

    SEEING REDWhen youre out at night checking

    out the stars, its always best to stick to

    red light.

    It takes twenty to thirty minutesor

    your eyes to adjust to the darkness, and

    once youre there itd be a pity to shockthem back into indoor mode. Te

    cells in our eye that let you see in the

    dark (the rods) cant detect red light, so

    a red flashlight doesnt disturb them.

    A secret amongst thrify astronomers

    is to wrap the ront o a flashlight with

    red cling wrap. You can also get tail light

    tape rom a local auto-parts store and

    tape right over the top. I youre eeling

    ancy you can also order a flashligh

    that comes with a red bulb.I youre relying on your phone to do

    the guiding, most stargazing apps have

    a night mode, where they replace

    anything white - text, lines, star marks

    - with red instead. Youll probably want

    to turn down the brightness, too, just to

    be sae.

    A little caution goes a long way in

    keeping your eyes adjusted and the

    stars bright!

    Believe it or not, this doesnt haveanything to do with the red lights in

    darkrooms! Paper used or making

    photographic prints just happens to be

    less sensitive to red light, so photographer

    and astronomers accidentally ended up

    having something in common.

    When you go out to stargaze, waiting hal an hour can make allthe difference in the world.

    Made o seven stars that plenty o

    ten-year-olds can pick out o the night

    sky, the Big Dipper is the perect

    starting point or a guided tour o the

    night sky.

    Because o the tilt o the Earths orbit,

    some constellations come and go with

    the seasons. For most o the Northern

    Hemisphere, though, the Big Dipper

    is circumpolar (it never sets). Given a

    dark enough night and the ability to

    draw lines in the sky, youre halway to

    finding plenty o constellations.

    Next time youre out, use the charts

    on the ollowing ew pages to track

    your way between the constellations.

    Note: Leo isnt out until the all, but

    we went ahead and lef it in!

    Dubhe and Merak are the stars at the

    as the Pointers, they help draw a line to

    Polaris, the North Star.

    Polaris is also the tail o Ursa Minor

    and the handle o the Little Dipper, so

    its two or one!

    Once youve ound Polaris, you can

    use it to track down Cassiopeia. Polaris

    should be right about in the middle

    o the Big Dipper and Cassiopeia, and

    Cassiopeia will look like a big, bright

    W sitting on its side.

    You can find Deneb by drawing a line

    Vega.

    While Denebs distance makes it

    seem much dimmer than Vega, its

    actually 4,000 times brighter!

    Along with a third stair, Altair, Deneb

    and Vega orm an asterism called the

    Summer riangle, which usually sits

    high in the sky late on summer nights.

    (boo-OH-tees). While Botes has been

    around or thousands o years, noones sure exactly which mythologica

    herdsman it reers to.

    Arcturus also has the pleasure o

    being the base o the most un asterism

    in the sky, the Ice Cream Cone(Botes

    minus the two spurs off o Arcturus)

    Follow that curve a little urther

    youll run right into Spica. Spica isn

    the brightest star around (it ranks 15th

    in the night sky), but it does mark the

    constellation Virgo.
