'Supermoon' Rises: Biggest Full Moon in 18 Years Occurs Saturday

Thanks to a fluke of orbital mechanics that brings the moon closer to Earth than that it has been in more than 18 years, the biggest full moon of 2011 will occur on Saturday, leading some observers to dub it a "supermoon." On Saturday afternoon at 3 p.m. Eastern Daylight Time, the moon will arrive at its closest point to the Earth in 2011:  a distance of 221,565 miles (356,575 kilometers) away. And only 50 minutes earlier, the moon will officially be full.
At its peak, the supermoon of March may appear 14 percent larger and 30 percent brighter than lesser full moons (when the moon is at its farthest from Earth), weather permitting. Yet to the casual observer, it may be hard to tell the difference. 
 

Spotting the supermoon

The moon has not been in a position to appear this large since March 1993.

In December 2008, there was a near-supermoon when the moon turned full four hours away from its perigee – the point in its orbit that is closest to Earth. But this month, the full moon and perigee are just under one hour apart, promising spectacular views, depending on local conditions. 

Although a full moon theoretically lasts just a moment, that moment is imperceptible to ordinary observation.

During the day or so before and after, most will speak of seeing the nearly full moon as "full," with the actual shaded area of the lunar surface being so narrow – and changing in apparent width so slowly – that it is hard for the naked eye to tell whether it's present, or which side it is.

In addition, the near coincidence of Saturday’s full moon with perigee will result in a dramatically large range of high and low ocean tides. 

The highest tides will not, however, coincide with the perigee moon but will actually lag by up to a few days depending on the specific coastal location. For example, in Wilmington, N.C., the highest tide (5.3 feet) will be attained at 11:21 p.m. EDT on March 20. 

In New York City, high water (5.9 feet) at The Battery comes at 10:49 p.m. EDT on March 21, while at Boston Harbor, a peak tide height of 12.2 feet comes at 1:31 a.m. EDT on March 22, almost 2 1/2 after perigee.

According to the Observer’s Handbook of the Royal Astronomical Society of Canada, residents of regions along the shores of the Bay of Fundy in eastern Canada, the 10- to 20-foot (3- to 6-meter) swell in the vertical tidal range makes it obvious when the moon lies near perigee, regardless of clear skies or cloudy.

Any coastal storm at sea around this time will almost certainly aggravate coastal flooding problems. 

Such an extreme tide is known as a perigean spring tide, the word spring being derived from the German springen – to "spring up," and is not, as is often mistaken, a reference to the spring season. 

In contrast, later this year, on October 11, the full moon will closely coincide with apogee, its farthest point from the Earth.  In fact, on that night the moon will appear 12.3 percent smaller than it will appear this weekend.

Big full moon's appearance is deceiving

And while this weekend’s moon will be – as the Observer’s Handbook suggests – the "largest full moon of 2011," the variation of the moon's distance is not readily apparent to observers viewing the moon directly. 

Or is it?

When the perigee moon lies close to the horizon, it can appear absolutely enormous. That is when the famous “moon illusion” combines with reality to produce a truly stunning view.

For reasons not fully understood by astronomers or psychologists, a low-hanging moon looks incredibly large when hovering near trees, buildings and other foreground objects. The fact that the moon will be much closer than usual this weekend will only serve to amplify this strange effect.

How to make your own image signature.

 Let me show you how make an image signature of your own..but on other sites since this site doesn't have the access to put signatures every time you post something. some of those signatures i uploaded on the other forum on mine
Well it is very easy, and I will give you screenies showing you how it is done.

NOTE: you DO NOT need any designing program. All you need is regular paint, and some ideas.

This is just a selected color background banner.

1st: Go to paint- How to access paint?

2nd: Choose the size of of the banner- How to size the banner?- Now find the image you choose, and select it.

3rd: Pick a background color- How to set a background?

4th: Adding your user name to the banner- How to add text?
NOTE: you can also add any other text you would like to be shown.

There see that wasn't hard to do.

Making a banner out of pictures.


1st: Go to www.google.com now select images search. Find a image that you want to be the background of you're banner.

2nd: Save that image to you're "My Pictures" folder.

3rd: Now go to paint, and you are ready to make you're banner!

4th: Open you're photo- How to open photo's?

5th: Size the image to the size you want it. Now add text to the image like we did on the last one.

Earth-like planet found!



HATFIELD, England – In the search for Earth-like planets, astronomers zeroed in Tuesday on two places that look awfully familiar to home. One is close to the right size. The other is in the right place. European researchers said they not only found the smallest exoplanet ever, called Gliese 581 e, but realized that a neighboring planet discovered earlier, Gliese 581 d, was in the prime habitable zone for potential life.

"The Holy Grail of current exoplanet research is the detection of a rocky, Earth-like planet in the 'habitable zone,'" said Michel Mayor, an astrophysicist at Geneva University in Switzerland.

An American expert called the discovery of the tiny planet "extraordinary."

Gliese 581 e is only 1.9 times the size of Earth — while previous planets found outside our solar system are closer to the size of massive Jupiter, which NASA says could swallow more than 1,000 Earths.

Gliese 581 e sits close to the nearest star, making it too hot to support life. Still, Mayor said its discovery in a solar system 20 1/2 light years away from Earth is a "good example that we are progressing in the detection of Earth-like planets."

Scientists also discovered that the orbit of planet Gliese 581 d, which was found in 2007, was located within the "habitable zone" — a region around a sun-like star that would allow water to be liquid on the planet's surface, Mayor said.

He spoke at a news conference Tuesday at the University of Hertfordshire during the European Week of Astronomy and Space Science.

Gliese 581 d is probably too large to be made only of rocky material, fellow astronomer and team member Stephane Udry said, adding it was possible the planet had a "large and deep" ocean.

"It is the first serious 'water-world' candidate," Udry said.

Mayor's main planet-hunting competitor, Geoff Marcy of the University of California, Berkeley, praised the find of Gliese 581 e as "the most exciting discovery" so far of exoplanets — planets outside our solar system.

"This discovery is absolutely extraordinary," Marcy told The Associated Press by e-mail, calling the discoveries a significant step in the search for Earth-like planets.

While Gliese 581 e is too hot for life "it shows that nature makes such small planets, probably in large numbers," Marcy commented. "Surely the galaxy contains tens of billions of planets like the small, Earth-mass one announced here."

Nearly 350 planets have been found outside our solar system, but so far nearly every one of them was found to be extremely unlikely to harbor life.

Most were too close or too far from their sun, making them too hot or too cold for life. Others were too big and likely to be uninhabitable gas giants like Jupiter. Those that are too small are highly difficult to detect in the first place.

Both Gliese 581 d and Gliese 581 e are located in constellation Libra and orbit around Gliese 581.

Like other planets circling that star — scientists have discovered four so far — Gliese 581 e was found using the European Southern Observatory's telescope in La Silla, Chile.

The telescope has a special instrument which splits light to find wobbles in different wavelengths. Those wobbles can reveal the existence of other worlds.

"It is great work and shows the potential of this detection method," said Lisa Kaltenegger, an astronomer at the Harvard-Smithsonian Center for Astrophysics.
