Earth 'to get second sun' as supernova turns night into day

The Earth could soon have a second sun, at least for a week or two.

The cosmic phenomenon will happen when one of the brightest stars in the night sky explodes into a supernova.

And, according to a report yesterday, the most stunning light show in the planet’s history could happen as soon as this year.
Earth will undoubtedly have a front row seat when the dying red supergiant star Betelgeuse finally blows itself into oblivion.

The explosion will be so bright that even though the star in the Orion constellation is 640 light-years away, it will still turn night into day and appear like there are two suns in the sky for a few weeks.

The only real debate is over exactly when it will happen.

In stellar terms, Betelgeuse is predicted to crash and burn in the very near future. But that doesn’t necessarily mean you have to rush out and buy sunglasses.

Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland in Australia, claimed yesterday that the galactic blast could happen before 2012 – or any time over the next million years.

‘This old star is running out of fuel in its centre,’ Dr Carter told te Austalian website news.com.au.

‘This fuel keeps Betelgeuse shining and supported. When this fuel runs out the star will literally collapse in upon itself and it will do so very quickly.

‘This is the final hurrah for the star. It goes bang, it explodes, it lights up - we’ll have incredible brightness for a brief period of time for a couple of weeks and then over the coming months it begins to fade and then eventually it will be very hard to see at all,’ he added.
The Internet is abuzz with doomsday theories linking the supernova to the Mayan calendar’s prediction of an Armageddon in 2012, fuelled by the association of the word ‘Betelgeuse’ with the devil.

But experts claimed that even if the big bang is looming, it will still happen way too far from Earth to do us any harm.

‘When a star goes bang, the first we will observe of it is a rain of tiny particles called nuetrinos,’ said Dr Carter.

‘They will flood through the Earth and bizarrely enough, even though the supernova we see visually will light up the night sky, 99% of the energy in the supernova is released in these particles that will come through our bodies and through the Earth with absolutely no harm whatsoever.’

When it happens, the Betelgeuse supernova will almost certainly be the most dramatic ever seen.

It is the ninth brightest star in the night sky and the second brightest in the constellation of Orion, outshining its neighbour Rigel – or Beta Orionis – only very rarely.

It’s distinct orange-red colour makes it easy to spot in the night sky.

If it was at the centre of our solar system, its surface would extend past the asteroid belt, wholly engulfing Mercury, Venus, Mars and the Earth.

Getting down to the nitty-gritty: Amazing microscopic images of household objects

They're innocuous objects that are dotted around every home.

But when brought to life under a powerful microscope their hidden secrets are revealed - and it doesn't always make for comfortable viewing.

Scientists captured these stunningly detailed pictures using Scanning Electron Microscopes (SEMs).

The images are of items found in various domestic settings, from the bathroom to the kitchen.

A mascara brush looks like you'd imagine it to under extreme magnification, but a section of used dental floss is rather unsettling despite its bright colouration.

Elsewhere, every tiny contour of salt and ground pepper corns is revealed in extraordinary detail.
SEMs work by bombarding the object with electrons and then build extreme close-ups of the image using a computer and transmission electro microscopes.

The images are produced in monochrome and then hand-tinted to enrich their detail.

SEMs are far more powerful than regular light microscopes that can only magnify by up to 1,000 times.



Retired scientific photographer Steve Gschmeissner is grateful that he still has access to an SEM - their high price tag makes them unaffordable to all but the most wealthy enthusiast.

Mr Gschmeissner, from Bedford, said: 'For anyone involved in microscopy the SEM is the ultimate boy's toy.

'Costing between £150,000 and £500,000, there are only a handful of people around the world who have access to this for fun. To be able to use equipment like this when I am retired is a dream come true.

'The SEM picks up basically where the normal light microscope finishes. And it takes it so much further by magnifying the specimen by up to a million times.

'Also different to a regular microscope is the fact the SEM builds a 3D image giving you a unique view.'

Earlier this year (see Part 1), we examined some of the cool, the fascinating, the unusual and the utterly weird designs for motorcycles that have appeared for over the last century or so. Here’s another look the wild and wonderful world of motorcycles.

Brough Superior motorcycles were made in Nottingham, England from 1919 until 1940 and were known as ‘the Rolls Royce of motorcycles’. Very expensive at the time, they were available only to the wealthy. This model dates from 1931.
T. E. Lawrence, better known as Lawrence of Arabia, owned several of these machines and died from his injuries after crashing on one in 1935... Another beautiful bike is this Imme (Germany), with a single side suspension:
The Megola motorcycle was produced in Munich in the 1920’s. Some 2000 were built, but only 10 fully working examples are still in existence, one of which is in the Guggenheim Museum in New York:
In 1935, the Killinger and Freund motorcycle was an attempt to make an improved version of the Megola, but the advent of World War Two put an end to any further development:

Some sources point out that "in 1940, when Indian's skirted fenders appeared, several questioned the manhood of Spingfield's designers". It seems that aerodynamic shape of Killinger & Freund bikes influenced the Indian designers:
This streamlined torpedo is the French-made Majestic, 1929:
Speaking about "Custom War Bikes", here is one that was fashioned after World War Two style (modern concept by Kogisama):

The previous wild concept was not so wild, after all - take a look at the real WW2-period 1936 BMW Schneekrad
Another front-wheel tracked motorcycle prototype from 1937
Modern all-terrain tracked version is proposed by Hyanide & Baal:
After the war, the Moto Guzzi 500 cc V8 race bike was seen on the world’s high-speed racetracks from 1955 to 1957.

Modern version of the hubless wheel can be seen in the recent concepts for Harley Davidson, by designer Miguel Cotto
Many of us remember the lightcycles from the 1982 movie Tron. The long awaited sequel, Tron Legacy, is set to hit theatres in late 2010 and will feature this splendid looking specimen:
Swordfish concept chopper:
Rats & Kustoms

This custom built motorcycle, called Iceman II, was made by Walz Hardcore Choppers of Germany for Formula One world champion Kimi Raikonnen:
Rat bikes are usually defined as motorcycles that are decades old, in a poor state of repair, but still maintained and kept roadworthy by their owners on a shoestring budget. Survival bikes do resemble rat bikes and the two are often confused, although survival bikes are usually modified in much the same way that cars are customized. Here are some great examples of both of these types of machines.

Imagine seeing this coming up behind you in your rear view mirror (below left)? On the right is the rounded green beauty, also seen at the Sturgis Motorcycle Rally:
Not sure what kind of a view you’d get of the road ahead on this one (image below left)? On the right you can see a really inventive fuel tank -


On the left image below is The Survival Bike from some sort of Zombie Apocalypse... Whereas the owners of the bike (below right) decided to actually attach the coffin as a sidecar:


We featured what we had speculated might be the world’s largest motorcycle in Magnificent Motorcycles Part One, but the biggest one on the planet may actually be this one.
This bike is pretty big too and apparently this machine, called the Gunbus, is perfectly capable of being taken out on the road.

Want to travel in style? Why not try this Harley Davidson and limousine combination?
Concept Beasts

Finally, here’s a selection of concept motorcycles, which may or may not see the light of day at some point in the future. Here’s the Akira concept bike:
FuturA was designed by Mario Malagrino of the Florence Design Academy (left)... Romanian 3D artist Adrian Baluta created this cool bike called Darklight (right):
