今天清晨,澳洲北部的居民和好几千名游客亲眼目睹了一场罕见的日全食。
在当地时间上午 5点45分(新加坡时间上午 8点15分),当月亮开始移向太阳和地球之间,形成一个天狗吃月的景象。观看这场奇观的人,目不转睛地盯着渐渐变大的日食。
当遮挡日食的云开始散去,观看的人顿时大声喝彩,因为终于可以目睹一个完整的日全食。月亮必须完全遮盖太阳,并在周围露出昏暗的光环, 才算得上是一个日全食。
日全食发生时,就连动物鸟儿都静了下来,四周骤然鸦雀无声。诡异的静谧迎来了昏暗的天空,地面的温度也开始下降。
这场自然奇观吸引了世界各地超过百万名旅客到访。昆士兰政府估计,有约5至6万名旅客慕名而来。
在北半球,每410年日全食才会在同一个地方再度出现,而南半球则需要540年。
南太平洋最后一次的日全食出现在2010年7月11日。

Sky-gazers in awe of total eclipse

Sky-gazers in awe of total eclipse

PALM COVE, Australia - Sky-gazers in northern Australia donned protective glasses as the clouds parted Wednesday to allow them to witness one of nature's greatest phenomena - a total eclipse of the sun.
All eyes and cameras turned to the heavens over tropical north Queensland as the moon began moving between the Earth and the sun, like a small bite which gradually increases in size.
Cloud cover threatened to spoil the party and huge cheers erupted when they parted to give tens of thousands of eclipse hunters a perfect view of totality - when the moon completely covers the sun and a faint halo or corona appears.
"Wow, insects and birds gone quiet," one tourist, Geoff Scott, tweeted.
Another, Stuart Clark, said: "This it it. Totality now. Utterly beautiful." The path of the eclipse got under way shortly after daybreak when the moon's shadow, or umbra, fell in the Garig Gunak Barlu National Park in the Northern Territory, about 250 kilometres (155 miles) east of Darwin.
The umbra then moved eastward before alighting in north Queensland - one of the few places it could be viewed by humans and where tourists and scientists flocked to witness the region's first total solar eclipse in 1,300 years.
Totality lasted just over two minutes from 6.38am (2038 GMT Tuesday). When it happened the early chatter of birds and animals was replaced by an eerie silence as the moon overtook the sun, casting a shadow that plunged the land into darkness, with temperatures dropping.
"Day into night, unbelievable, goosebumps, speechless, amazing," said Palm Cove eclipse watcher Simon Crerar. Fred Espenak, an American astrophysicist and world authority on eclipses, told the Australian Broadcasting Corporation that while eclipses can seem somehow magical, in fact they can be predicted accurately.

"Certainly within 100 to 200 years we can predict when an eclipse will occur to within a second," he said.
"But the pattern of occurrence is a complicated one. They don't repeat on a time schedule like the seasons of the year."
He explained that when a total eclipse occurred "the darkest part of the moon's shadow sweeps across the earth's surface".
"Total solar eclipses occur once every one to two years but are only visible from less than half a percent of the earth's surface," he said.
The rare spectacle, which was viewed live by millions around the world, drew thousands of eclipse tourists to Queensland with the state government estimating that 50,000-60,000 people made the trip.
They include three charter flights with 1,200 scientists from Japan while six cruise ships were moored off the coast and hot air balloons dotted the skies. Accommodation was solidly booked - from five-star hotels to camping grounds.
Scientists will study the effects of the eclipse on the marine life of the Great Barrier Reef and Queensland's rainforest birds and animals while psychologists will monitor the impact on humans.
Total eclipses can be seen from a given point on Earth's surface only once every 410 years in the northern hemisphere, but only once every 540 years in the southern hemisphere.
The last total eclipse was on July 11, 2010, again over the South Pacific. The next will take place on March 20, 2015, occurring over Iceland, the Faroe Islands and Norway's far northern Svalbard archipelago, according to Espenak.

Singaporeans gather to see lunar eclipse

Singaporeans gather to see lunar eclipse
By Qiuyi Tan | Posted: 11 December 2011 0000 hrs

SINGAPORE: Hundreds gathered at Marina Bay on Saturday evening to witness a total lunar eclipse, a rare view in Singapore.

Some moongazers were happy to use telescopes offered by the local astronomical community, Singastro.

A total eclipse only happens during a full moon. It occurs when the moon passes through the Earth's shadow.

Channel NewsAsia's camera crew caught the very start of the celestial event, around 7.30pm, when the bottom left of the moon started to darken.

The eclipse can also be seen in other parts of the world, from Alaska to Central Asia and Australia.

Total lunar eclipse set for Africa, Middle East, Central Asia

Total lunar eclipse set for Africa, Middle East, Central Asia
Posted: 15 June 2011 1938 hrs
     
PARIS - Astronomers in parts of Europe, Africa, Central Asia and Australia were hoping for clear skies on Wednesday to enjoy a total lunar eclipse, the first of 2011 and the longest in nearly 11 years.

A total lunar eclipse occurs when Earth casts its shadow over the Moon.

The lunar face can sometimes turn reddish, coppery-brown or orange, tinged by light from the Sun that refracts as it passes through our atmosphere.

The terrestrial shadow starts to fall at 1724 GMT and lifts at 2300 GMT, although "totality" -- when the lunar face is completely covered -- runs from 1922 to 2102 GMT, according to NASA's veteran eclipse-watcher, Fred Espenak.

The 100-minute period of totality is the longest since July 2000.

"The entire event will be seen from the eastern half of Africa, the Middle East, Central Asia and western Australia," says Espenak.

"Observers throughout Europe will miss the early stages of the eclipse because they occur before moonrise. Fortunately, totality will be seen throughout the continent except for northern Scotland and northern Scandinavia."

Eastern Asia, eastern Australia and New Zealand will miss the last stages of the eclipse because they occur after moonset.

Totality will be visible from eastern Brazil, Uruguay and Argentina. None of the eclipse will be visible from North America, though.

The next total lunar eclipse is on December 10.

There will be partial solar eclipses on July 1 and November 25. The next total solar eclipse will take place on 13 November 2012, in a track running across North Australia, New Zealand, the South Pacific and southerly South America.

Solstice lunar eclipse set for December 21st

Everyone knows that "the moon on the breast of new-fallen snow gives the luster of mid-day to objects below." That is, except during a lunar eclipse.

See for yourself on Dec. 21st, the first day of northern winter, when the passes almost dead-center through Earth's shadow. For 72 minutes of eerie totality, an amber light will play across the snows of North America, throwing landscapes into an unusual state of ruddy shadow.

The eclipse begins on Tuesday morning, Dec. 21st, at 1:33 am EST (Monday, Dec. 20th, at 10:33 pm PST).
At that time, Earth's shadow will appear as a dark-red bite at the edge of the lunar disk. It takes about an hour for the "bite" to expand and swallow the entire Moon. Totality commences at 02:41 am EST (11:41 pm PST) and lasts for 72 minutes.

If you're planning to dash out for only one quick look -­ it is December, after all -­ choose this moment: 03:17 am EST (17 minutes past midnight PST). That's when the Moon will be in deepest shadow, displaying the most fantastic shades of coppery red.

Why red?
A quick trip to the Moon provides the answer: Imagine yourself standing on a dusty lunar plain looking up at the sky. Overhead hangs Earth, nightside down, completely hiding the sun behind it. The eclipse is underway. You might expect Earth seen in this way to be utterly dark, but it's not. The rim of the planet is on fire! As you scan your eye around Earth's circumference, you're seeing every sunrise and every sunset in the world, all of them, all at once. This incredible light beams into the heart of Earth's shadow, filling it with a coppery glow and transforming the Moon into a great red orb.

Back on Earth, the shadowed Moon paints newly fallen snow with unfamiliar colors--not much luster, but lots of beauty.

Enjoy the show.

The 2010 Lunar Eclipse

The 2010 Lunar Eclipse
Different to solar eclipse that can just be noticed from a particular relatively small portion of the globe, lunar eclipse can be seen from anywhere on the evening side of the Earth. This type of eclipse endures for a couple of hours, wherein total eclipse endures for just a couple of minutes at any given area. Few lunar eclipses have been related with significant historical occurrences.

The 2010 lunar eclipse take place on June 26, 2010, and shall be seen in different places of the US. It shall likewise be clear in Australia and the eastern portions of Asia. People residing in Central North America as well as Western portions of the US will not be able to observe the lunar eclipse freely. The said eclipse will last for approximately 3-hours. This scheduled lunar eclipse is said to be special for the kids who haven’t seen lunar eclipse in their lives. The 2010 lunar eclipse is truly unique because of the illusion of the moon, which NASA already confirmed.
 
NASA has provided a list of places that shall see this eclipse, established a detailed analysis about the eclipse, and has revealed the forecast of the occurrence on its web site.

Lunar eclipse is making us feel that we exist in such a huge universe and we are just a small portion of it. The big creations such as the sun and moon have superb influence on humankind. Seeing this eclipse through our naked eye can lessen the eyesight power of a human. The full moon has powerful effect on the water in the oceans; colossal tidal waves are developed within the water because of the gravitational force of the moon.

370 solar eclipse enthusiasts in Singapore stay indoors due to rain

370 solar eclipse enthusiasts in Singapore stay indoors due to rain
By Jessica Yeo, Channel NewsAsia

SINGAPORE : 370 Singaporeans gathered at the Singapore Science Centre to catch the solar eclipse on Wednesday morning, but they ended up staying indoors because of the rain which resulted in poor visibility.

10 per cent of the eclipse could have been seen in Singapore between 8:41am and 9:43am, with its optimum position at 9:11am.

The next eclipse is expected on 15 January 2010, and Singaporeans will be able to catch 30 per cent of it.

But Singapore will have to wait until 2019 for the annular eclipse if residents want to see the moon's shadow totally cast on the sun.

"The eclipse is caused by the moon casting a shadow on the Earth and this time round, the path of the shadow passes through the densely populated areas in China. Singapore happens to be literally at the fringe of the activity," said Dr Chew Tuan Chiong, CEO of Singapore Science Centre.

Solar eclipse pits superstition against science

Solar eclipse pits superstition against science


MUMBAI (AFP) – Indian astrologers are predicting violence and turmoil across the world as a result of this week's total solar eclipse, which the superstitious and religious view as a sign of potential doom.

But astronomers, scientists and secularists are trying to play down claims of evil portent in connection with Wednesday's natural spectacle, when the moon will come between the Earth and the sun, completely obscuring the sun.

In Hindu mythology, the two demons Rahu and Ketu are said to "swallow" the sun during eclipses, snuffing out its life-giving light and causing food to become inedible and water undrinkable.

Pregnant women are advised to stay indoors to prevent their babies developing birth defects, while prayers, fasting and ritual bathing, particularly in holy rivers, are encouraged.

Shivani Sachdev Gour, a gynaecologist at the Fortis Hospital in New Delhi, said a number of expectant mothers scheduled for caesarian deliveries on July 22 had asked to change the date.

"This is a belief deeply rooted in Indian society. Couples are willing to do anything to ensure that the baby is not born on that day," Gour said.

Astrologers have predicted a rise in communal and regional violence in the days following the eclipse, particularly in India, China and other Southeast Asian nations where it can be seen on Wednesday morning.

Mumbai astrologer Raj Kumar Sharma predicted "some sort of attack by (Kashmiri separatists) Jaish-e-Mohammad or Al-Qaeda on Indian soil" and a devastating natural disaster in Southeast Asia.

An Indian political leader could be killed, he said, and tension between the West and Iran is likely to increase, escalating into possible US military action after September 9, when fiery Saturn moves from Leo into Virgo.

"The last 200 years, whenever Saturn has gone into Virgo there has been either a world war or a mini world war," he told AFP.

It is not just in India that some are uneasy about what will transpire because of the eclipse.

In ancient China they were often associated with disasters, the death of an emperor or other dark events, and similar superstitions persist.

"The probability for unrest or war to take place in years when a solar eclipse happens is 95 percent," announced an article that attracted a lot of hits on the popular Chinese web portal Baidu.com.

Sanal Edamaruku, president of the Indian Rationalist Association, dismissed such doomsday predictions.

"Primarily, what we see with all these soothsayers and astrologers is that they're looking for opportunities to enhance their business with predictions of danger and calamity," he told AFP.

"They have been very powerful in India but over the last decade they have been in systematic decline."

Astronomers and scientists are also working to educate the public about the eclipse.

Travel firm Cox and Kings has chartered a Boeing 737-700 aircraft to give people the chance to see the eclipse from 41,000 feet (12,500 metres).

Experts will be on board to explain it to passengers, some of whom have paid 79,000 rupees (1,600 dollars) for a "sun-side" seat on the three-hour flight from New Delhi.

The eclipse's shadow is expected to pass over the aircraft at 15 times the speed of sound (Mach 15), said Ajay Talwar, president of the SPACE Group of companies that promotes science and astronomy.

"It's coming in the middle of the monsoon season. On the ground, there's a 40 percent chance of seeing it in India. On the aircraft you have almost a 90 percent chance of seeing the eclipse," he added.

Siva Prasad Tata, who runs the Astro Jyoti website, straddles the two worlds.

"There's no need to get too alarmed about the eclipse, they are a natural phenomenon," the astrologer told AFP.

But he added: "During the period of the eclipse, the opposite attracting forces are very, very powerful. From a spiritual point of view, this is a wonderful time to do any type of worship.

"It will bring about good results, much more than on an ordinary day."


What will happen tomorrow?
