Re: [astronomy-121] wasnt mars supposed to be around in August?

Hi all,

Thanks for that post. That hoax is silly. 

I saw Mars last night with my scope. It rises in the northeastern sky. You won't see it til 2 or 230am right now (cause of the NY haze). I Could easily see the ice cap through my scope.  It's dim til it rises above the haze. 

Was looking at Jupiter, Neptune and Uranus too. Great red spot was visible and was watching 1 of the moons pass in front of the planet (Jupiter).  Real nice.

If it's clear this weekend I'll be out there. If anyone wants to join me just let me know.

Hi:

I am not sure when this meetup actually meets up, but here is some information about a hoax email that is circulating regarding Mars appearing as big as the moon August 27, 2009.  This is from earthsky.org.

Fwd: SEE TWO MOONS ON 27TH AUGUST. 2009 Should be spectacular! Truly a once in a lifetime experience!

It���s happening again. People are clamoring for information about an amazing spectacle involving the red planet Mars. An email is circulating suggesting that ��� on August 27, 2009 ��� Mars will appear as large as a full moon in Earth���s sky. The version I saw actually included a powerpoint presentation, suggesting that Mars and Earth���s moon will appear as a ���double moon��� in late August 2009.

It sounds amazing! Can it possibly be true?

No. It can���t. The email is a hoax. It has circulated every summer since 2003. Mars can never appear as large as a full moon as seen from Earth, and Mars will not even be at its brightest in August of 2009.

In fact, in August of 2009 Mars is a relatively inconspicuous dot of reddish light in our eastern predawn sky. It did appear near the moon this month ��� a waning crescent moon visible before dawn ��� on the morning of August 16. That waning moon might have made Mars slightly more conspicuous than it would have otherwise been. Now the moon has moved on in its orbit around Earth, leaving Mars behind, and unless you know exactly what you are looking for, you probably will have trouble finding Mars for the rest of this month.

Ah, Mars. World of dreams and visions. Mars is the world orbiting one step outward from Earth���s orbit. This world is slightly smaller than Earth ��� but slightly larger than Earth���s moon. Mars is also much much farther away than Earth���s moon. It���s hard to comprehend what little specks the planets and moons are in contrast to the vastness of space, but let me put it this way. Earth���s moon is about a light-second away. Traveling at 186,000 miles per second, light bouncing from the moon���s surface takes about a second to reach us here on Earth. Meanwhile, light from Mars takes much much longer to reach Earth ��� from several minutes to about 20 minutes ��� with the difference being the result of Earth���s and Mars��� motions around the sun. In other words, when Mars is on the same side of the sun as Earth, its distance from us is less than when it���s on the far side of the sun from us.

The moon is much closer than Mars, and that���s why we see the moon as a bright disk in our sky. Meanwhile ��� to the eye ��� Mars never appears as anything but a ���star.���

So how did this rumor of Mars-as-big-and-bright-as-the-moon get started? It started with an actual event, in 2003. On August 27 of that year, Earth and Mars came very slightly closer than they���d been in nearly 60,000 years. Our two worlds, center-to-center, were about 35 million miles apart ��� just over three light-minutes apart. The last people to come so close to Mars were Neanderthals. Astronomy writers like me had a field day that year, talking about Mars at its closest. Was it a spectacular sight? Yes! It looked like a dot of flame in the night sky. But was Mars as big and bright as the moon, even at its closest in 2003? Never.

What is happening on August 27 of 2009? Nothing, really. By coincidence, there will be a reddish star near the moon on August 27, the star Antares in the constellation Scorpius. The name Antares or Ant-ares means ���rival of Mars.��� Antares is sometimes called Mars��� rival because both Antares and Mars appear reddish, and because the planet Mars sometimes appears brighter than this star.

This August, though, Antares appears brighter than Mars does in Earth���s sky. Will some people look outside on August 27 ��� see Antares near the moon ��� and think this reddish star is Mars?

Probably.

And so the legend continues

thank you for the info; I kind of thought it was Venus; can't wait to have a telescope meeting somewhere; can't get on my roof anymore and really, really miss looking at the sky.

Hi

It's probably Venus. Mars rises like 130
Am or so. Visible after 2 or so. Venus rises later on. It's really bright ad you describe.

there's a very, very bright planet in the East in the pre-dawn hours; is that Mars or Venus?

That was when everyone said that Mars would be the size of the moon in the earth's sky. Thank God we have science to counter these urban legends!  Tonight, Mars should be near the moon still, even in Asia!  May have changed a bit in the past 4 days but not by too much!

If you���re up before dawn on Sunday morning ��� the morning of August 16 ��� you can use the waning crescent moon to locate the planet Mars. Look for Mars about two finger-widths to the moon���s right or upper right. (Hold your two fingers an arm length away.)

Jawad,

You are probably reading a very exaggerated description of the opposition from Aug. 2003.

  http://www.snopes.com/science/astronomy/brightmars.asp

Right now the best planet to see is probably Jupiter, which should be easy to pick out if you look towards the south at night time.

I am currently vacationing in Asia and I dont see mars at all. From what I read, mars was supposed to be the brightest object in the night sky and even visible at daytime all over the world. Does anyone know what happened? Is it visible in NYC?
