11 phenomenal images of earth
below are 11 incredible photos taken from space which illustrate just a few of earth’s fascinating geographical features and nature’s frightening unpredictability.
click on all pictures for humongous versions.
1. Aurora borealis
(above) an astounding and spooky photo of the natural phenomenon known as aurora borealis, taken on-board space shuttle atlantis during the sts-117 mission.2. mt. etna eruption, october 2001
(above) taken from the international space station in 2001, this is a photo of a particularly violent eruption on the island of sicily which produced a cloud of ash that travelled as far as libya. on the humongous version of the photo lighter coloured smoke can be seen near the volcano - this was caused by lava igniting nearby forests.3. hurricane isabel, 2003
(above) this terrifying photo of hurricane isabel was taken on the international space station in 2003 and illustrates the immense size of the hurricane’s eye. this particular hurricane was the deadliest of 2003 and winds reached 165 mph at its peak.4. Sri lankan coast, 26th december 2004
(above) the ocean rapidly retreats 400 metres on the south-western coast of sri lanka, just 5 minutes prior to the arrival of a devastating tsunami.
(above) the swirling waters continue to batter the coast just moments after the main wall of water has hit.5. egmont national park, new zealand
(above) mt. egmont volcano last erupted in 1755 and is now situated at the centre of egmont national park. park regulations have ensured the survival of a forest which extends at a 9.5 km radius from the summit of the volcano, the result of which can be seen from space in the form of huge dark green disc. this photo was taken during the sts-110 mission, april 2002.6. an alluvial fan, xinjiang province, china
(above) covering an area 56.6 x 61.3 km and taken on may 2nd, 2002, this photo shows an alluvial fan that formed on the southern border of the taklimakan desert in china. an alluvial fan usually forms as water leaves a canyon, each new stream eventually closing up due to sediment - the result being a triangle of active and inactive channels. the blue ones on the left are currently active.7. retreating glaciers in the bhutan-himalaya
(above) a beautiful but clear sign that glaciers are slowly melting due to global warming. easily visible are the ends of most of these glacial valleys’ surfaces turning to water to form lakes, a trend which has been noticed only in the last few decades.8. richat structure, mauritania
(above) the cause of the richat structure in the sahara desert of mauritania has been debated for many years. at first it was thought to be a meteor impact crater due to its circularity but this has since been disproven due to the lack of shock-altered rock in its vicinity. this massive (30 mile diameter) oddity is now believed to have been a rock dome sculpted over time by erosion. this incredible image was taken by the advanced spaceborne thermal emission and reflection radiometer (aster) on october 7th, 2000.9. a total solar eclipse from space, 1999
(above) the shadow of the moon covers part of earth on august 11th, 1999 in this photo taken from mir space station. this shadow raced across earth at 2000 km/h, all areas under the centre of it plunged into darkness during a total solar eclipse. this was apparently one the final photos taken from mir.10. greenland’s eastern coast, august 21st, 2003
(above) the fractal coastline of greenland and its numerous fjords as seen from space.‘little spots of white in the water seem to be ice originating from the deeper fjords that reach all the way to the icecap covering most of the island.’
Tree man 'who grew roots' may be cured
An Indonesian fisherman who feared that he would be killed by tree-like growths covering his body has been given hope of recovery by an American doctor - and Vitamin A.
Dede, now 35, baffled medical experts when warty "roots" began growing out of his arms and feet after he cut his knee in a teenage accident.
The welts spread across his body unchecked and soon he was left unable to carry out everyday household tasks.
Sacked from his job and deserted by his wife, Dede has been raising his two children - now in their late teens - in poverty, resigned to the fact that local doctors had no cure for his condition.
To make ends meet he even joined a local "freak show", parading in front of a paying audience alongside victims of other peculiar diseases.
Although supported by his extended family, he was often a target of abuse and ridicule in his rural fishing village.
But now an American dermatology expert who flew out to Dede's home village south of the capital Jakarta claims to have identified his condition, and proposed a treatment that could transform his life.
After testing samples of the lesions and Dede's blood, Dr Anthony Gaspari of the University of Maryland concluded that his affliction is caused by the Human Papilloma Virus (HPV), a fairly common infection that usually causes small warts to develop on sufferers.
Dede's problem is that he has a rare genetic fault that impedes his immune system, meaning his body is unable to contain the warts.
The virus was therefore able to "hijack the cellular machinery of his skin cells", ordering them to produce massive amounts of the substance that caused the tree-like growths known as "cutaneous horns" on his hands and feet.
Dede's counts of a key type of white blood cell are so low that Dr Gaspari initially suspected he may have the Aids virus.
But tests showed he did not, and it became clear that Dede's immune condition was something far rarer and more mysterious.
Warts aside, he had enjoyed remarkable good health throughout his life - which would not be expected of someone with a suppressed immune system - and neither his parents nor his siblings have shown signs of developing lesions.
"The likelihood of having his deficiency is less than one in a million," Dr Gaspari told the Telegraph.
Dr Gaspari, who became involved in the case through a Discovery Channel documentary, believes that Dede's condition can be largely cleared up by a daily doses of a synthetic form of Vitamin A, which has been shown to arrest the growth of warts in severe cases of HPV.
"He won't have a perfectly normal body but the warts should reduce in size to the point where he could use his hands," Dr Gaspari said.
"Over the course of three to six months the warts should be come smaller and fewer in number. He will be living a more normal life."
The most resilient warts could then be frozen off and the growths on his hands and feet surgically removed.
Dr Gaspari hopes to get the necessary drugs free of charge from pharmaceutical firms. They would then be administered by Indonesian doctors under his supervision.
Still intrigued by the origins of Dede's peculiar immune condition, the doctor would like to fly him to the United States for further examination, but fears the financial and bureaucratic barriers would prove too difficult to overcome.
"I would like to bring him to the US to run tests on where his immune condition has come from, but I would need funding and to get him a visa as well as someone to cover the costs of the tests," he said.
"I've never seen anything like this in my entire career."
