Winds at twice the speed of sound

We’ve all got stuck out in or witnessed very strong winds here on Earth, from gusts that turn your umbrella inside out to tornadoes that rip up everything in their path. You might think these winds are a force to be reckoned with, but unless you’ve had a day floating around the gaseous atmosphere of ice giant Neptune you haven’t seen anything yet!

You might think that Neptune’s distance from the Sun, which creates temperatures as low as -218 degrees Celsius (-360 degrees Fahrenheit), would mean a world frozen solid by the subzero climate with not much going on in

The most unlikely addition to the transport infrastructure of London is nearing completion in the East End. More about the Emirates Air Line, a cable car to link the Royal Albert Dock with Greenwich

The London skyline is becoming increasingly eclectic. The bulbous Gherkin (Foster + Partners), the towering Shard (RPBW) and the wind-turbine-topped, elongated-barcode that is the Strata tower (BFLS) will soon be joined by the Cheese Grater (RSHP), the Boomerang (Ian Simpson and Partners) and the Walkie-Talkie (RVA).

Aside from high-rise towers, there have been more eccentric and, in some cases, more loved additions that peek above the rooftops. The London Eye, at first implemented as a temporary attraction, has become one of the most recognisable modern additions to the capital’s silhouette. The Arcelor Mittal tower in the Olympic Park wriggles skywards

The most powerful forces in the universe.

All About Space runs for cover as we explore the objects in the cosmos that pack the biggest punches of all.

The universe is an incredibly violent place, populated by explosions and torrents of radiation, pulled this way and that by powerful fundamental forces, and lit up by active centres of galaxies and massive stars. All these forces are in interplay -supernovas create black holes, while gravity battles dark energy to decide the fate of the universe. Energies far greater than the Sun can produce in 10 billion years are wielded in a matter of seconds, and our knowledge of

The Moon

The most visible celestial object from Earth has been the source of human fascination for millennia, yet we’re still discovering more about it all the time.

Orbiting at a distance of anywhere between 362,570 kilometres and 405,410 kilometres (225,000 to 252,000 miles) and moving away from the Earth at almost four centimetres (1.57 inches) per year, all 74 billion trillion kilograms (160 billion trillion pounds) of blasted grey rock that is the Moon never fails to make for fascinating viewing. Its topography is a pattern of ‘maria’ – impact basins once filled with lava – and giant craters that are

THE MIKOYAN-Gurevich MiG-31 Foxhound is one of the most powerful interceptors flying today. It owes its outstanding capability to a combination of performance, weaponry, and avionics. Even though it first flew more than 30 years ago, it is still Russias most effective air defence interceptor. The aircraft forms the backbone of its air defence force and will continue to do so well into the 21st century.

Development

In the late 1960s, the Soviet Government began the search for a new long-range, extended endurance interceptor to replace its Tupolev Tu-28s and MiG-25 Foxbats. It was intended to counter the threat of low-flying cruise missiles launched from NATO/US B-52s and B-ls, which the MiG-25 was unable to do. MiG-25s functioned well as high-altitude interceptors with the help of ground control data links, as their original mission was to intercept the USAF’s high-altitude Mach 3 B-70 Valkyrie bomber. However, the B-70 never went into production on account of defence cutbacks. The Foxbat’s avionics and performance were largely ineffective against

THE HOLY TRINITY

The best phones in the world run Android. The best Androids ore this Samsung, Sony and HTC. Sophie Charara finds out which is best of the best… of the best.

A smartphone is the most important weapon in your gadget arsenal. That means choosing the right smartphone is pretty damned difficult — and this is especially true today. You see, not long ago we would have automatically recommended the iPhone; it was the best option on many levels, so the only decision to make was how much built-in storage to plump for. But now that Android rules the roost, with

Some of Japans most dominant companies owe their success not only to technology and process expertise but also to an often-overlooked factor:

During the past decade, they’ve been quietly turning their supplier relationships into a tool for innovating faster while radically cutting costs. Welcome to the new keiretsu—a modern version of the country’s traditional supply system.

During its heyday, in the 1980s, the traditional keiretsu system—an arrangement in which buyers formed close associations with suppliers—was the darling of business schools and the envy of manufacturers everywhere. Although there was some tentative movement in the West toward keiretsu- like supplier partnerships at the time, the rise of manufacturing in lowwage countries soon made cost the preeminent concern. Most Western companies today wouldn’t dream

Sitting Pretty.

Porches boost log homes’ looks and livability.

Porches are so prominent a fixture of log homes that the only reason they aren’t the number-one option log-home buyers order (and fireplaces are) is that most people just automatically assume log homes come with a porch. Fortunately, most do.

Of course, most log homes also have decks, but don’t confuse decks with porches. Decks are attachments to a house, porches are connections to it. The connection is physical, because porches are integrated into the structure by sharing a roof, and emotional, because popular domestic imagery celebrates porches as havens of hospitality, meditation

Searching for monster stars

In 2010, Professor Paul Crowther and his team discovered the most massive known single star, R136a1.

Can we start by asking what first drew your attention to the R136 star cluster?

Well, it’s probably the prime target for anyone looking for the most massive stars – it’s the most obvious place to look really because it’s the most massive young star cluster in our part of the universe. It’s about the same size as the famous Orion Nebula, but while that’s got a couple of thousand stars, R136 probably contains 100,000 stars or more, if you could see them all.

THIS BOOK has been written by members of the Veneto Military Aviation Society and translated into English by the very capable Frank McMeiken to provide an insight into activities at Aviano Air Base in north-east Italy from 1954-92. For those Italian speakers among you there is a separate booklet in the back, providing the text in Italian.

The curious title of the book is explained by the fact that landings and departures mainly use
