Imagine peacefully sailing in the ocean when suddenly a 40-ton, 30-foot-long whale flips into the air and crashes onto your boat! That’s exactly what happened to Paloma Werner and Ralph Mothes in the waters off Cape Town, South Africa, this past week.

This amazing photo was taken by a tourist seconds before the whale landed on the boat, thrashing about and damaging its steel mast and cabin. The huge mammal then returned to the ocean. The sailors weren’t hurt, but it was still a frightening surprise.

“It really was quite incredible but very scary,” said Werner. “We thought the whale was going to go under the boat and come up on the other side. We thought it would see us. But instead it sprang out of the sea.”

The whale left blubber and skin on the boat. According to a marine scientist, the whale was probably badly bruised but did not seriously injure itself.

Why exactly do whales breach, or flip themselves, out of the water? Scientists have differing theories. They think whales might do this simply for fun, or it could have a purpose, such as cleaning barnacles and other sea debris from the skin. No matter what the reason, whales rarely land on boats when they breach, which is a good thing for sailors and these extraordinary sea creatures.

‘Avatar is real’, say tribal people

Avatar’s story is being played out in real life.

Reposted from “For the Next 7 Generations” blog…originally posted at Survival.org “The Movement for Tribal Peoples” 25 January 2010

Following the film ‘Avatar’’s win at the Golden Globes, tribal people have claimed that the film tells the real story of their lives today.

A Penan man from Sarawak, in the Malaysian part of Borneo, told Survival, ‘The Penan people cannot live without the rainforest. The forest looks after us, and we look after it. We understand the plants and the animals because we have lived here for many, many years, since the time of our ancestors.

‘The Na’vi people in ‘Avatar’ cry because their forest is destroyed. It’s the same with the Penan. Logging companies are chopping down our big trees and polluting our rivers, and the animals we hunt are dying.’

Kalahari Bushman Jumanda Gakelebone said, ‘We the Bushmen are the first inhabitants in southern Africa. We are being denied rights to our land and appeal to the world to help us. ‘Avatar’ makes me happy as it shows the world about what it is to be a Bushman, and what our land is to us. Land and Bushmen are the same.’

Davi Kopenawa Yanomami, known as the Dalai Lama of the Rainforest, said, ‘My Yanomami people have always lived in peace with the forest. Our ancestors taught us to understand our land and animals. We have used this knowledge carefully, for our existence depends on it. My Yanomami land was invaded by miners. A fifth of our people died from diseases we had never known.’

Director James Cameron received his Golden Globes awards for ‘Avatar’ last week, and revealed one of the central ideas of the film.

‘Avatar asks us to see that everything is connected,’ he said in his acceptance speech, ‘All human beings to each other, and us to the earth.

Cameron was inspired by the Maori language of New Zealand when devising the language spoken by the Na’vi.

Survival’s director Stephen Corry says, ‘Just as the Na’vi describe the forest of Pandora as ‘their everything’, for most tribal peoples, life and land have always been deeply connected.

‘The fundamental story of Avatar – if you take away the multi-coloured lemurs, the long-trunked horses and warring androids – is being played out time and time again, on our planet.

‘Like the Na’vi of ‘Avatar’, the world’s last-remaining tribal peoples – from the Amazon to Siberia – are also at risk of extinction, as their lands are appropriated by powerful forces for profit-making reasons such as colonization, logging and mining.’

‘One of the best ways of protecting the our world’s natural heritage is surprisingly simple; it is to secure the land rights of tribal peoples.’

COMET MCNAUGHT: 6.9.10 Update

A fresh comet is swinging through the inner solar system, and it is brightening rapidly as it approaches the sun. Presenting, Comet McNaught (C/2009 R1):

Amateur astronomer John Chumack of Yellow Springs, Ohio, caught the comet passing by galaxy NGC 891 just before sunrise on June 8th. “I used a 5.5 inch telescope and a Canon Rebel Xsi digital camera to take this 15 minute exposure,” he says. “It also looked great through binoculars.”

Comet McNaught can be found low in the northeastern sky before dawn gliding through the constellation Perseus. It is brightening as it approaches Earth for a 1.13 AU close encounter on June 15th and 16th. Currently, the comet is at the threshold of naked eye visibility (6th magnitude) and could become as bright as the stars of the Big Dipper (2nd magnitude) before the end of the month. Because this is the comet’s first visit to the inner solar system, predictions of future brightness are necessarily uncertain; amateur astronomers should be alert for the unexpected.

COMET McNAUGHT: Originally posted 6.8.10 at spaceweather.com

A fresh comet is swinging through the inner solar system, and it is brightening rapidly as it approaches the sun. Presenting, Comet McNaught (C/2009 R1):

Michael Jäger of Stixendorf, Austria, took the picture on June 6th using an 8-inch telescope. The comet’s green atmosphere is larger than the planet Jupiter, while the long willowy ion tail stretches more than a million kilometers through space. These dimensions make the comet a fine target for backyard telescopes.

Interesting information about earth changes revealed by Chile earthquake, from MSNBC

Chile is on a hotspot of sorts for earthquake activity, according to a Live Science report. And so the 8.8-magnitude temblor that shook the region overnight was not a surprise, historically speaking. Nor was it outside the realm of normal, scientists say, even though it comes on the heels of other major earthquakes.

One scientist, however, says that relative to the time period from the mid-1970s to the mid-1990s, Earth has been more active over the past 15 years or so. 

The Chilean earthquake, and the tsunami it spawned, originated on a hot spot known as a subduction zone, where one plate of Earth’s crust dives under another. It’s part of the active “Ring of Fire,” a zone of major crustal plate clashes that surround the Pacific Ocean.

“This particular subduction zone has produced very damaging earthquakes throughout is history,” said Randy Baldwin, a geophysicist with the U.S. Geological Survey.

The largest quake ever recorded, magnitude 9.5, occurred along the same fault zone in May 1960.

Even so, magnitude-8 earthquakes occur globally, on average, just once a year. Since magnitudes are given on a logarithmic scale, an 8.8-magnitude is much more intense than a magnitude 8, and so this event would be even rarer, said J. Ramón Arrowsmith, a geologist at Arizona State University.

“Relative to the 20-year period from the mid-1970s to the mid 1990s, the Earth has been more active over the past 15 or so years,” said Stephen S. Gao, a geophysicist at Missouri University of Science and Technology. “We still do not know the reason for this yet. Could simply be the natural temporal variation of the stress field in the earth’s lithosphere.” (The lithosphere is the outer solid part of the Earth.)
