Rainbow Cloud

Photographer captures rare 'fire rainbow cloud' above Florida as Mother Nature puts on spectacular light show

• Ken Rotberg spotted unusual phenomenon as sun dropped behind a storm cloud in the early evening
•  Rare sight also known as a 'circumhorizon arc'

• Looking up into the night sky, a stunned photographer realised he had seen something special when he captured these amazing pictures.

What perhaps looks like a multi-coloured flying saucer is in fact a rare weather phenomenon known as a 'fire rainbow cloud'.

The series of photographs were taken by Ken Rotberg as the cloud hovered over south Florida, America.

Mr Rotberg had just returned home from a game of tennis when he saw the odd sight as the sun dropped behind a storm cloud near Delray Beach in the early evening.

Rainbow Eucalyptus–The Most Colorful Tree on Earth

These trees may look like they've been painted on, but these colors are all natural. This peculiar tree is called Eucalyptus deglupta, commonly known as the Rainbow Eucalyptus, and also known as the Mindanao Gum, or the Rainbow Gum. The multi-coloured streaks on its trunk comes from patches of outer bark that are shed annually at different times, showing the bright-green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones.

Eucalyptus deglupta is the only Eucalyptus species found naturally in the Northern Hemisphere. It grows naturally in New Britain, New Guinea, Ceram, Sulawesi and Mindanao. Now, this tree is cultivated widely around the world, mainly for pulpwood used in making paper, and also for ornamental purposes.
