Like the ghost of a dear friend dead
Is Time long past.
A tone which is now forever fled,
A hope which is now forever past,
A love so sweet it could not last,
Was Time long past.

There were sweet dreams in the night
Of Time long past:
And, was it sadness or delight,
Each day a shadow onward cast
Which made us wish it yet might last -
That Time long past.

- Percy Bysshe Shelley

The United States was not the only country to name a new leader last week. In Bhutan, an insular nation of about 600,000 people located high in the Himalayas, a new king was crowned. 28-year-old Jigme Khesar Namgyel Wangchuck, an Oxford-educated bachelor, was crowned as Bhutan's fifth king - now the world's youngest reigning monarch. Bhutan also has the distinction of being the world's youngest democracy - having held parliamentary elections last March for the first time ever. The young ruler vows to maintain a stance of protection against the worst aspects of globalization, maintaining the "Gross National Happiness", a measurement of national progress that places a high value on spiritual development. Gross National Happiness is a term invented by, and proudly embraced by Bhutanese since 1972.

With medieval tradition and Buddhist spirituality, a 28-year-old with an Oxford education assumed the Raven Crown of Bhutan on Thursday, to guide the world's newest democracy as it emerges into the modern world.

Berlin is the capital city and one of sixteen states of Germany. With a population of 3.4 million within its city limits, Berlin is the country's largest city. It is the second most populous city and the ninth most populous urban area in the European Union. Located in northeastern Germany, it is the center of the Berlin-Brandenburg metropolitan area, comprising 5 million people from over 190 nations.

Potsdamer Platz, the centerpiece of Berlin, is a collection of futuristic high-rise office buildings and a pedestrianised forum with shops, cinemas, cafes and restaurants designed by some of the world's most celebrated architects.

The Bode Museum belongs to the group of museums on Museum Island in Berlin and is a historically preserved building. The museum was designed by architect Ernst von Ihne and completed in 1904. Originally called the Kaiser-Friedrich-Museum after Emperor Frederick III, the museum was renamed in honor of its first curator, Wilhelm von Bode, in 1956.

The current Reichstag dome is an iconic glass dome constructed on top of the rebuilt Reichstag building in Berlin. It was designed by architect Norman Foster and built to symbolize the reunification of Germany. The distinctive appearance of the dome has made it a prominent landmark in Berlin.  read more »

Every year, peculiar apparitions appear on the cliffs between popular Sydney beaches Bondi and Tamarama, yet not even the gulls take fright at the annual Sculpture by the Sea exhibition - Australia's largest annual outdoor free exhibition of sculpture. This year, more than 100 sculptures from seven countries, including Japan, the US, Iceland and New Caledonia, are on display on the cliff tops or around the rocky foreshore, expecting to attract 500,000 sightseers.

For David Handley, who founded the event 12 years ago, its popularity never ceases to surprise. "I would have needed therapy if you'd told me 12 years ago how big it was going to be," he says. "You wouldn't believe how much work goes on behind the scenes, but once Sydney responded the way it did, you just can't stop."

What is photography for? Can it change our minds? An exhibition just opened at Paris’s Palais de Tokyo, of the 18 photographers short listed for the first Prix Pictet, poses these questions loud and clear.

The Pictet prize, established this year by Pictet & Cie, one of Switzerland’s largest private banks, and co-sponsored by the Financial Times, is the only international photography prize that concerns itself directly with sustainable development and environmental issues. In that sense it isn’t quite a conventional art prize but an award – of 100,000 Swiss francs (SFr) – to be given annually to the artist who best uses the power of the camera to communicate a vital dispatch on one of the most serious issues facing us all.

Wealthy nations are reneging on commitments to help feed the world's hungry and may cite the banking crisis as a reason why they cannot do more, former U.N. Secretary-General Kofi Annan told an international conference on combating starvation. Annan's address emphasized that 10,000 children in the Third World would die from malnutrition on World Food Day alone - and this should be viewed as great a tragedy as the collapse of a bank. "The financial crisis deserves urgent attention and focus. But so does the question of hunger. Millions (this year) are liable to die. Is that any less urgent?" Annan told journalists at the Fighting Hunger conference attended by 200 foreign-aid experts from Europe, Africa and the United States.

British engineers have unveiled plans for the world's first 1,000-mph car, a muscular streak of gunmetal and orange designed not to break the world land speed record but to shatter it. Bloodhound SSC, named after the British cold war supersonic air defence missiles, will attempt to beat the existing record by more than 250mph.

The £12m car is to be announced today by Lord Drayson, the science minister. Working from an aircraft hangar in Bristol, the team's engineers have been working on the project in secret for the past 18 months. Calculations suggest the car could reach 1,050mph, fast enough to outrun a bullet from a .357 Magnum revolver. The car was proposed by Drayson, a racing car enthusiast, as a project to inspire a new generation of scientists and engineers, who are in desperately short supply in UK. The Bloodhound team plans to have the car built within a year, with the record attempt expected in three years.

A sweeping prominence, a huge cloud of relatively cool dense plasma is seen suspended in the Sun's hot, thin corona. At times, prominences can erupt, escaping the Sun's atmosphere. Emission in this spectral line shows the upper chromosphere at a temperature of about 60,000 degrees K (over 100,000 degrees F). Every feature in the image traces magnetic field structure. The hottest areas appear almost white, while the darker red areas indicate cooler temperatures.

The Sun is now in the quietest phase of its 11-year activity cycle, the solar minimum - in fact, it has been unusually quiet this year - with over 200 days so far with no observed sunspots. The solar wind has also dropped to its lowest levels in 50 years. Scientists are unsure of the significance of this unusual calm, but are continually monitoring our closest star with an array of telescopes and satellites. Seen here are some recent images of the Sun in more active times.

A transit of the Moon across the face of the Sun on February 25, 2007 - but not seen from Earth. This sight was visible only from the STEREO-B spacecraft in its orbit about the sun, trailing behind the Earth. NASA's STEREO mission consists of two spacecraft launched in October, 2006 to study solar storms. STEREO-B is currently about 1 million miles from the Earth, 4.4 times farther away from the Moon than we are on Earth. As the result, the Moon appears 4.4 times smaller than what we are used to.

Over Earth and Ocean, with gentle motion,
This pilot is guiding me,
Lured by the love of the genii that move
In the depths of the purple sea;
Over the rills, and the crags, and the hills,
Over the lakes and the plains,
Wherever he dream, under mountain or stream,
The Spirit he loves remains;
And I all the while bask in Heaven's blue smile,
Whilst he is dissolving in rains.

Ice sculptures constructed from the spare core samples by the scientists working on the North Greenland Eemian Ice Drilling project.

The ice samples, which the researchers analyze for clues to the temperature and concentration of greenhouse gases of the ancient atmosphere, are collected using this drill.

The visiting group of scientists, journalists and Danish environmental officials land at NEEM, the North Greenland Eemian Ice Drilling project. NEEM had arranged for the visitors to examine their research, which focuses on the climatic conditions which shaped the warm geologic period before the earth's last Ice Age, an important clue in understanding global warming. The camp is located approximately 600 miles north of the Arctic Circle.  read more »

The new Moon drew its shadow across Earth's Eastern Hemisphere earlier today, totally eclipsing the Sun along a track that crossed the Arctic, Siberia, and interior China. Thousands of eclipse chasers had stationed themselves along the path in anticipation. The Moon's shadow arced over the Earth as the lunar body passed directly between our planet and its star. In all, the path of darkness covered about 10,200km (6,300 miles). Russia saw the longest full eclipse, for two minutes, 27 seconds, at 1021 GMT - but the UK and most of Europe experienced just a partial eclipse.

"Totality" began at sunrise at 0921 GMT in Queen Maud Gulf off Victoria Island in the territory of Nunavut, Canada. The instant of greatest eclipse occurred at 1021 GMT close to the Russian city of Nadym, before totality came to an end at 1121 GMT near the Chinese city of Xi'an, in Shaanxi province.

Tourists and amateur and professional astronomers flocked to towns in the best viewing locations along the path of totality. In Novosibirsk, Siberia's cultural and scientific capital, more than 5,000 foreign tourists were expected to show up in the city. China experienced the eclipse just a week before the opening ceremony of Beijing's Olympic Games. Chinese TV was due to broadcast the eclipse live, with crowds of people gathered along the Silk Road, a fabled trading route through the country's western deserts. Eclipses were once viewed as unlucky events in China, but the country's media had rebranded the event as "the Olympic eclipse", reports said, hoping for good fortune ahead of the sporting jamboree.

The eclipse allowed astronomers a glimpse of the Sun's corona - its outer atmosphere of super-heated gases. The area is usually impossible to see because of the bright light of the Sun, but is visible during a total eclipse as the Sun's light is obscured. Total solar eclipses usually take place about once every 18 months, and always at new Moon - when the lunar body sits directly between the Sun and the Earth. However, they do not happen every new Moon. The lunar orbit is slightly tilted to that of our planet and therefore the Moon's shadow often misses the Earth.

The world's next total eclipse of the Sun comes less than a year from now, on July 22, 2009. It will begin at sunrise in India, cross parts of Nepal, Bangladesh, Bhutan, Burma, and thickly inhabited areas of China, and will end at sunset over the South Pacific. The next total solar eclipse for North America comes on August 21, 2017. The path of totality will sweep from Oregon to South Carolina.

The Moon's shadow has two parts: an umbra and a penumbra. The umbra is the "inner" part of the Moon's shadow, and people inside this zone will witness the full glory of the eclipse. The penumbra is the Moon's faint "outer" shadow. It will only give surface viewers a partial eclipse.

In London, where the Moon's disc took its biggest bite out of the Sun at 1016 BST (0916 GMT), a maximum of 12% of the star was blotted out. Conditions were better further north. In Lerwick in the Shetland Isles, the Moon obscured as much as 36% of the Sun.

Astronomical groups reminded the public that viewing the Sun without protective equipment - even in partial eclipse phases - could result in a retinal burn and permanent eye damage. Viewing the Sun's harsh light should only be done through proper solar telescopes or glasses, or through a pinhole projection system.

The announcement by NASA of the discovery of water ice on Mars by its Phoenix Lander probe made big news everywhere. The discovery involved the observation of water ice sublimating into the air - that is, the water went from solid to vapor state without reaching the liquid stage. The Martian atmosphere has perfect conditions for sublimation - extremely thin, dry and cold. How cold? Well, you can check the Live Martian Weather Report, with data from a station on board the Phoenix Lander.

What more do we know about Mars' atmosphere? It's hundreds of times thinner than Earth's atmosphere and is made of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen, water, and methane. We also know, from observations that it can support dust storms, dust devils, clouds and gusty winds. With an amazing number of six current live probes exploring Mars (two rovers, a lander, and three orbiters), there are many thousands of images available. Only a few, however show atmospheric phenomena. Presented here are some of the best images of Martian atmosphere (and beyond) in action.
