Amazing, The Astronomy Photographer of the Year competition 2013

An image of Venus crossing the sun over the Black Sea in Romania and astral clouds of rose-coloured gas revealing star formations in distant galaxies are just two of the incredible images shortlisted for the 2013 Astronomy Photographer of the Year competition.
The competition, which is now in its fifth year, is run by the Royal Observatory Greenwich in association with Sky at Night Magazine.
It received a record number of over 1,200 entries from enthusiastic amateurs and professional photographers from around the globe.


A vast sweep of auroral light appears to mirror the shape of the frozen shoreline in this photograph by Mike Curry
The natural rock archway of Durdle Door, frames the distant band of our Milky Way in this shot by Stephen Banks.The rock formations on Dorset's Jurassic Coast are more than 100 million years old but many of the stars that make up the Milky Way are far older, at up to ten billion years old

The Carina Nebula is a chaotic region of star formation several thousand light years from Earth. In the central part of the nebula, shown here, dense clouds of gas and dust are lit up by the light of newly born stars. The star Eta Carinae is at the centre of this image by Michael Sidonio

Wayne England managed to catch the moment when the Milky Way appears to line up with the giant 64 metre dish of the radio telescope at Parkes Observatory in Australia. As you can see from the artificial lights around the telescope, light pollution is not a problem for radio astronomers

This photograph by Rogelio Bernal Andreo shows the Milky Way arching over Yosemite Valley in California's famous national park. A lens-shaped (lenticular) cloud hovers over the distinct granite dome of Liberty Cap, which rises to an elevation of over 2,000 metres

Transits of Venus are rare events, occurring in pairs eight years apart, with each pair separated by more than a century. The transits themselves are brief, as Venus only takes around 6 hours to cross the disc of the Sun. Alexandru Conu captured the event in Romania (pictured left). On the right, Tommy Eliassen photographed a bright meteor streaking across the sky

Although auroral displays have become more common as the Sun nears the peak of its 11 year cycle of activity in 2013, these hilltop observers were still lucky to witness such a spectacular example and were photographed by James Woodend

As the full Moon sinks in the west, the Sun rises in the east, lighting up the snow-capped Alpine horizon, captured by Stefano De Rosa
The birth of new stars is a complex process. One aspect of stellar formation is the production of jets of material which blast out from the poles of some new-born stars. Here, these jets can be seen emerging from the thick dust and gas clouds of the Pelican Nebula, as photographed by Andre van der Hoeven

Although a line of burnt orange along the horizon marks where sunset has already occurred, most of the light in this image by Ingólfur Bjargmundsson comes from the Sun. High in the sky the bright disc of the Moon is shining with reflected sunlight, while a tiny smudge above the sea is sunlight reflecting from the dust and gas in the tail of Comet Panstarrs

This full disc image of the Sun, captured by Paul Haese, shows dark filaments rising from the surface and back again. These features are known as prominences

Noctilucent clouds are formed of tiny ice crystals high in the atmosphere around 80km above the ground and can be seen at Twilight. Here, despite the urban lights, they are photographed above the Pennine Hills of northern England by Mark Shaw
Modern cameras can detect light which is too faint for our eyes to see. Nik Szymanek has chosen a subdued palette of colours to represent the Orion Nebula to emphasise the delicate structure of the nebula's dust clouds

Familiar stars and constellations form a line rising up behind this windswept tree in Dartmoor National Park in the southwest of England. Just above the horizon is Sirius, the brightest star in the sky, photographed by Anna Walls

Jabuticaba: The Tree That Bear Fruits on its Trunk


Jabuticaba is a Brazilian grape tree found in the states of Minas Gerias and Sao Paulo, in the south of Brazil. The fruit grows directly from the trunk and branches of the tree, which gives the Jabuticaba tree a very unusual appearance. The fruit itself is a small and round, about 3 to 4 cm in diameter, with one to four large seeds, a thick, deep purple colored skin and a sweet, white or rosy pink gelatinous flesh. Naturally the tree may flower and fruit only once or twice a year, but when continuously irrigated it flowers frequently, and fresh fruit can be available year round in tropical regions. During Jabuticaba season in Minas Gerais, thousands of street vendors sell fresh Jabuticaba in small net bags, and the sidewalks and streets are stained the same deep purple by discarded Jabuticaba skins.

 

Jabuticaba is largely eaten fresh, but because the fruit starts to ferment just 3-4 days after harvest, they are often used to make jams, tarts, strong wines, and liqueurs. Due to the extremely short shelf-life, fresh Jabuticaba fruit is very rare in markets outside of areas of cultivation. The fruit also has many medicinal uses. Traditionally, an astringent decoction of the sun-dried skins has been used as a treatment for hemoptysis, asthma, diarrhoea, and gargled for chronic inflammation of the tonsils. It also has several potent antioxidant and anti-inflammatory anti-cancer compounds.


Although the Jabuticaba grows in most regions of Brazil, it’s found mostly in Minas Gerias. It’s association with the state is so strong that the Jabuticaba tree appears on the coat of arms of the city of Contagem, and another city in Minas Gerais, Sabará, hosts a Jabuticaba festival annually.

Mosaiculture Exhibition 2013 at Montreal Botanical Garden


Considered the world’s most prestigious competition of horticultural art, the 2013 edition of Mosaiculture is currently on display at Montreal Botanical Garden in Quebec, Canada. More than three million flowers were raised in greenhouses throughout Quebec, and then shipped to the gardens in May, where designers wrapped them in steel meshes to create living works of art.

The sculptures are created using steel or aluminum forms that are wrapped in metal mesh, filled with earth and planted with flowers, ivies and grasses whose foliage provides texture and color. Interior watering systems and growing medium were added so that the flowers could last all through the summer till the end of the exhibition on September 29.
Some 50 works graces the 2.2 km circuit through the enchanting grounds of the Botanical Garden. The theme this year is “Land of Hope”. About 200 of the world’s most talented horticultural artists are taking part in this international competition, representing 20 countries. Entries have come from cities in countries as far as Turkey and Uganda, with China and Japan heavily represented.



The mosaiculture sculptures will complement the vast collection of 22,000 plant species and cultivars, some thirty thematic outdoor gardens, cultural gardens, Tree House and 10 exhibition greenhouses at Montreal Botanical Garden.

Mosaiculture originated in Montreal in 2000. It is now a prestigious international competition, staged every three years in a different city, with funding from governments and the private sector. Last time, it was held in Shanghai, before coming back to Montreal again.
Mosaiculture runs 9 a.m. to 7 p.m. every day until Sept. 29.
