The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

'Potentially hazardous' Asteroid...[ 3653 ]

Asteroid 2000 EM26: 'potentially hazardous' space rock to fly close to Earth

Space rock to pass by Earth 2.1m miles away, but astronomers say 270-metre object poses significant danger in case of impact

A "potentially hazardous" asteroid the size of three football fields will come uncomfortably close to Earth early on Tuesday.
The space rock, known as 2000 EM26, poses no threat and will pass the Earth at just under nine times the distance to the moon.
.
But it is defined as a potentially hazardous near-Earth object (NEO) large enough to cause significant damage in the event of an impact. Scientists estimate the asteroid, travelling at 27,000mph, is 270 metres (885ft) wide.
At its closest approach at 2am UK time, the rock will be 2.1m miles from Earth, or 8.8 lunar distances.
.
Images of the asteroid making its flyby will be captured by the Slooh robotic telescope service, which provides internet access to automated observatories.
2000 EM26 makes its appearance almost exactly a year after two major NEO events on 15 February 2013.
.
As scientists tracked a 30-metre wide asteroid that brushed by the Earth at a distance of 17,200 miles, another space rock unexpectedly exploded above Chelyabinsk, Russia.
The meteor, thought to measure 20 metres wide, released the energy of 20 atomic bombs 18 miles above the ground.
Thousands of buildings were damaged and many people injured by flying glass and debris, but no one was killed.
.
Slooh astronomer Dr Bob Berman said: "On a practical level, a previously unknown, undiscovered asteroid seems to hit our planet and cause damage or injury once a century or so, as we witnessed on 20 June 1908 and 15 February 2013.
.
"Every few centuries, an even more massive asteroid strikes us – fortunately usually impacting in an ocean or wasteland such an Antarctica. But the ongoing threat, and the fact that biosphere-altering events remain a real if small annual possibility, suggests that discovering and tracking all NEOs, as well as setting up contingency plans for deflecting them on short notice should the need arise, would be a wise use of resources."
