Giant Olympic Rings in River Thames London

A barge carrying a magnificent set of giant Olympic rings was launched on the London river to mark 150 days until the start of the Games.Measuring 11 metres (36ft) high and 25 metres (82ft) wide, the glowing display sailed regally through the city centre on a barge pulled along by a tugboat.

Mr Boris Johnson the Mayor of London, said "2012 is one of the most thrilling years in our city’s history and as we welcome the world, we have an unprecedented opportunity to showcase and strengthen London’s outstanding culture and creativity, which are a hugely important part of our economy.From museums to theatre, and music to design, we have a reputation that is second to none and London’s finest artists and organisations are producing an exceptional range of brand new cultural events that will add to the excitement of hosting the Games".

Amazing light graffiti of supercars

The images are the latest work of Marc Cameron and photographer Mark Brown. The duo are secretive about their exact methods but say they use a process of reflecting and refracting LED light to create outlines. Every detail of the vehicles is planned precisely before setting a camera on long exposure to catch the light painting. The entire process can take up to four hours.

Mrk Brown explains: “Using extended exposures I am able to step in front of the lens and paint with light using the camera as a canvas. Then I use real photographic components as a background for each of the light paintings. Nothing is digitally generated, only stitched together."

Stunning landscapes completed in months and years

Mr Wouter Van Buuren, a Dutch photographer, has spent seven years creating his stunning collection of images - with each individual portrait taking between two months and two years to complete.He scales 70m-high electricity pylons, cranes, bridges and even skyscrapers in a bid to take the vertigo-inducing snaps.He then spends months arranging the photographs to make up one huge landscape - giving the effect of looking down on the whole world.

Mr Van Buuren said: 'I started to make the "total landscapes" in the Netherlands when I was climbing in electricity pylons. I was stunned by the beauty of the landscape I thought I knew so well.When I looked at the landscape from above, the mundane seemed more divine, so I decided to look around for what else I could take images from - and started climbing cranes, bridges and buildings and other countries all over the world'.

Nature’s most spectacular sights

Photographer James Appleton from Cambridge braved the mighty flames of the Fimmvvrpuhals volcano and the frozen bite of the harsh Icelandic winter – and was rewarded with these incredibly rare shots.They capture two of nature’s most spectacular sights - the northern lights and an erupting volcano in Iceland - in a single shot.

Photographer James Appleton has spent the past seven years capturing the volatile and stunning landscapes of Iceland, and when he was told the Fimmvvrpuhals volcano was erupting, he immediately knew he had to see it.Working alongside vulcanologists, Mr Appleton, 25, got within a few hundred feet of the erupting volcano to get the perfect shot.

‘I never dared to hope it might actually happen, but seeing it for real put all the hairs on the back of my neck up.When I saw the photographs come through the camera I was jumping around with excitement.’ James Appleton said.

Mean machine Lamborghini Ankonian concept car

The Lamborghini Ankonian is a concept car by the Italian car maker, Lamborghini. Designed by designer Slavche Tanevsky, the Ankonian is a more aggressive version of Lamborghini's supercar, the Reventón. To make it more environmentally friendly, it is downsized; although it does not include any hybrid technology. The Ankonian is a mid engine sports car; and like most Lamborghini models, its name has some relation to bullfighting. This concept looks as if it was modeled off of a stealth jet fighter. It is not certain that the Ankonian will go into production.

Designer Tanevsky noted that his design goal was to take the Reventón design language to the "next level", strengthening the Reventón's agressivenes with 'underground' and 'hardcore' themes; The design achieves this using triangular forms and with the color combinations shiny black and matt dark grey.

Lighting up the dark

The images were taken throughout Japan the effect was achieved by using different exposures and apertures on his Nikon camera.The unique phenomena of lightning bugs being able to light up come from bioluminescence, which is created when a pigment and chemical react.

It is most often seen in sea creatures. According to io9.com, up to 90 per cent of marine life use bioluminescence. The astounding feat is often seen in deep sea trenches and other parts of the ocean where sunlight does not reach.Fireflies use two chemicals – luciferase and luciferin. The former glows when combined with the latter, which is an enzyme that triggers light emission.

Amazing Futuristic aircraft designs of Nasa

Our ability to fly at supersonic speeds over land in civil aircraft depends on our ability to reduce the level of sonic booms. NASA has been exploring a variety of options for quieting the boom, starting with design concepts and moving through wind tunnel tests to flight tests of new technologies.

This rendering of a possible future civil supersonic transport shows a vehicle that is shaped to reduce the sonic shockwave signature and also to reduce drag.
