Utterly Painful Ignorance on Display on ABC News!

[NOTE: Following is an updated edited version of my original post. The original post about this incident was written in my typical venomous no-holds-barred antagonistic tactless verbiage. Since then, I have gained a scientific respect for Erica Martin and am quite confident this was an inadvertent mistake that we all make from time to time.]

Well, now. The above image is a smartphone picture taken from my own living room TV while I was choking on a hunk of Birthday pizza 09/10/2012. I thought I heard wrong; a simple slip of the tongue, so to speak... But, NOOO!!!! Erika Martin, Meteorologist for Ch8 WTNH in CT, read this graphic.

It is wrong on so many levels, I can't begin to get my panties unbunched.

So, what's wrong with the info? Let's take a cursory look

1. The name, 2012 QG42, is correct.
2. 800 Miles wide? OMG! LOL! WTH! And other choice TLAs! Where the Hell did this thing come from? The largest asteroid in our entire solar system is Ceres at a meager 950 km (590 miles) wide.
FACT: 2012 QG42 is estimated at 800 FEET across! She is off by a factor of 5,280! Could be a graphics error.

The above image, compliments Wiki, shows, left to right, Vesta, Ceres, and our moon.

3. It is coming to within "1.8x10^-5 Miles"!! Like I said earlier; OMG, LOL, WTH! Quick conversions from scientific notation, moving the decimal point 5 places to the left gets us 0.000018 miles! That's 0.09 feet! 1.1 INCHES!!! THIS 800 MILE WIDE HUNK OF ROCK IS COMING WITHIN 1 INCH OF THE EARTH! WE"RE ALL DEAD! Run, Flee!
FACT: Closest approach is 1.8 MILLION Miles. Off by a magnitude of 11. You can't tell me that an ABC affiliate can't afford a text function that does superscripts! That number should read: 1.8 x 106 miles.

4. Telescope needed. Yeah, right... According to Sky and Telescope Magazine's Tony Flanders, "Locating this asteroid won’t be easy; it requires excellent chart-reading skills and planetarium software capable of showing stars down to magnitude 14.5."
FACT: I have a 10" Orion Dobsonian. I'd never be able to see it with my meager object-finding skills. WTNH, however, stated that, "Backyard astronomers will be able to see it whiz by Thursday night." "Whiz by"? Hardly. According to Tony Flanders, it is moving one arcsecond per clock second. Only trained folks watching it for extended lengths of time will see it move...

sigh...

Yet Another "Earth-Like" Planet Found... Yawn....

COOL, TOO KEWL! Earth-like planet found that MAY have been a larger hunk of rock that split up after an ugly encounter with it's star! As my Super-Hero colleague and close personal friend, The Tick, said, "Gravity is a harsh mistress..."

See: SPACE.COM for more info...

I'm still wrapping my head around CT Gov Malloy repealing the death penalty even though 67% of CT folks said it (repeal) was a bad thing... Sigh... Just when did our "representatives" become less than that...

SUPERMOON Going To Kill Us All This Weekend! AAARRRGGGHHH!

Seems there are plenty of reasons to believe that our own moon is going to [A] crash into us, or [B] cause severe tides so that Denver becomes beachfront property, or [C] get so close as to pull us off the surface of the earth and fling us all into outer space where we will all explode in a horrible frozen bloody death. Those reasons, in order, are [A] stupid people on the internet or [B] stupid people who read stupid things on the internet written by aforementioned stupid people on the internet or [C] stupid people who run blogs who report on stupid stories about stupid people who read stupid things on the internet written by aforementioned stupid people on the internet or, lastly, [D] folks who have previously claimed to have been abducted by aliens, probed in unspeakable ways, then returned to their loved ones to rattle on and on about being probed in unspeakable ways.

Now, as anyone who has ever paid attention to this hysteric type of thing, I can say demonstratively and succinctly that the moon is not, let me repeat, NOT going to kill us this weekend. Nor, is it going to drown, smite, set on fire, collide, send locusts or otherwise spell doom for mankind as set forth by the stupid "2012" subscribers. I much prefer to follow the Armageddon-ish view where Bruce Willis will save us from certain death from a rogue comet originating iron-core asteroid the size of Texas that no one saw till it was too late. [Soliloquy: I'm relatively confident I'd be able to scream to my neighbors, whom I hold no love for, "Look! Here comes Texas!" a few days before Micheal Bay and Jerry Bruckheimer decided the world need to see it...] Anyway, I digress... Which is not a bad thing...

Anyway, the Moon is at Perihelion this weekend, the closest approach to the Earth in it's sorta wide elliptical orbit. So, yeah. It's larger than normal. DURING THE MONTH! The last time it was this "large: was May 2011! OMG! That was before I was born! Wait... Maybe not...

Take a look:

So, yeah, duh.

Planets Putting On a Show This Month!!

Howdy! If you are even vaguely interested in viewing stars and planets and aliens, this is your month. The Giants Jupiter and Saturn are hanging out most of the night while all the little 'uns - Mars, Venus, & Mercury - are competing for your attention.

Let's start with the Little 'uns. Tonight, coincidentally, Mars is in what astronomers like to call "opposition". This doesn't mean it opposes us. It's simply that we are both on the same side of the sun and all lined up. Can you say, "Mayan disaster 2012"? I knew you could. Also, Mars is at it's closest approach to earth in it's 26 month orbit at about 63 Million miles away. This puts Mars prominently on any astronomer's list of "Things To See in March". And if you have a really good telescope, you might even see John Carter fighting 6-legged giant white gorillas in a Martian arena... Maybe not...

As for Mercury, well! This little elusive guy can't be seen very often due to its close proximity to that Million mile wide ball of fire in the sky. However, tonight, again coincidentally, Mercury makes its highest appearance in the western sky just after sunset. Find Venus and Jupiter, the two brightest things you can see right now other than the sun. Mercury is right beneath them, closer to the horizon.

The other Little Guy, Venus, is strutting her stuff as usual. Venus is lined up for the next several days with Jupiter. Both are big and bright and not necessarily in the heart of Texas. See image above.

Meanwhile, Saturn, the King of the Rings, not to be confused with the Lord of the Rings, should be giving telescope and good binocular viewers a ring show the rest of the month.

Top-Notch Meteor Shower This Week!

Bundle up warmly and head on outside between 1AM and 5AM Wednesday January 04 2012! The annual Quadratid Meteor shower promises to be a great show this year. This shower, although much briefer than some of its more famous cousins like the Leonids and Perceids, this one is bold and loud. Predictions range from 60 to 200 meteor streaks per hour during peak. Even the average of 120/hr yields a breathtraking 2 streaks per minute! WOWZERS!

Here are a few factoids and tips for watching:
1. BUNDLE UP! According to AccuWeather.com, Tuesday night/Wednesday morning is going to be bone-chillingly cold! Low temps are to be around 13oF. However, Weather.org claims it'll be serious Three Dog Night at only 9oF! Yes, that's cold enough to freeze your coffee and your little toes. So, be prepared! Lots of proverbial layers and a few "heat packs" wouldn't hurt.
2. The peak hour is expected to be 2-3AM. However, the waxing gibbous moon (what the heck is it waxing?) won't set till right around 3AM. The Moon's light will inhibit some viewing in areas where optimal conditions (See #3) don't exist.
3. Optimal Viewing? Find a spot away from bright lights. The darker the area, the better. Make it a family adventure. Pack a warm drink and several dozen good buffalo wings and head out to a park or secluded area.
4. The shower’s radiant (its apparent perspective point of origin) is in the not-well-known constellation Quadrans Muralis about halfway from the end of the Big Dipper handle to the head of Draco, as shown above. Quadrans Muralis is not one of the "modern" 88 constellations recognized by the IUA; it's an older However, if you aren't in my Astrology class, who'd know where the heck Draco is? So, I look for both Dippers; Big and Little. Make an imaginary line between them and then complete an imaginary equilateral triangle downwards so the third vertx is UNDER the Dippers. That 3rd vertex is the radiant. It’s fairly high up in the northeast after about 1 AM local time and keeps rising higher until dawn. The higher a shower’s radiant, the more meteors appear all over the sky. Watch whatever part of your sky is darkest, probably straight up.
5. The Quads are the result of an asteroid, not specifically from a comet like most other showers; Asteroid 2003 EH1.

So, bundle up and lead out to a dark place and have some fun with this! Next major metweor shower isn't till April's Lyrids.

New Moon Theory!

Well, I guess my Astro kids can call me a liar! I've been preaching for years about the "Big Crash" moon theory where a Mars-sized planet(oid) did a demolition derby thing with the earth long ago and the ejecta formed the moon. Well, there's a slightly new theory in town.

In Nature Magazine this month, comes an explanation on why the two "sides" of the moon are so different. The near-side, the one we see from earth, is mostly smooth while the far-side, the daunted "dark" side, is rough and mountainous and cratered and icky.







Following are images of near and far sides:




So, according to these guys, a Mars-sized panetoid did hit the earth, but formed TWO moons; one larger than the other. After a long time of gravity tugs at Lagrange points, the little guy smashed into the big guy and formed the back side. Also explains, differently than conventional theory, the tidal lock and why it faces us all the time. The little guy hit the big guy "slowly" so not much rock melted and no huge crater was formed. Just sorta covered one side with a thick layer of rock. This agrees with observation that the moon's crust is thicker on the back side.

Something to ponder.
