Transparent-Headed Fish

With a head like a fighter-plane cockpit, a Pacific barreleye fish shows off its highly sensitive, barrel-like eyes--topped by green, orblike lenses--in a picture released today but taken in 2004.
The fish, discovered alive in the deep water off California's central coast by the Monterey Bay Aquarium Research Institute (MBARI), is the first specimen of its kind to be found with its soft transparent dome intact.
The 6-inch (15-centimeter) barreleye (Macropinna microstoma) had been known since 1939--but only from mangled specimens dragged to the surface by nets

Fire Tornado

A fire whirl comes perilously close to homes during the Corona Fire on November 15, 2008, in Yorba Linda, California.

Fire tornadoes can set objects in their paths ablaze, and they can hurl burning debris out into their surroundings.

The winds generated by a fire tornado can also be dangerous. Large fire tornadoes can create wind speeds of more than a hundred miles (160 kilometers) an hour—strong enough to knock down trees.

The Colour of Clouds

When I was knee high to a grass hopper I loved to watch clouds. Maybe all children love to play the game of spotting animals in the shapes of the clouds. Bright white clouds on a clear blue sky look wonderful, and even as an adult it is easy to get lost in them.

White Clouds

But why are clouds white? The simple answer is that they reflect very well the light that falls on them. Clouds are illuminated by light from the sun, and light from the sun is seen as white by our eyes, a mix of all the colours of the rainbow - which produces white. Clouds are made up of many small water drops and ice crystals. Light can reflect and scatter so many ways from and in a cloud that when illuminated directly it ends up looking an fairly even and bright white.

Rainbows

A rainbow is caused by sunshine illuminating water drops usually in the form of rain, but it could be spray from a water fall or fountain. But a rainbow is not all over the place, it is always to be seen in a specific location in the sky with respect to the sun. A rainbow is always a 42 degree arc around the anti solar point. The anti solar point is the exact opposite spot from the sun, and is easily found as the shadow of your head. This is actually a cone 42 degrees around the anti solar point with the apex at your head. To see a rainbow there needs to be water drops some where in this thin cone which are illuminated by sun light.
