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

Spectacular Views ...[ 3409 ]

Cosmic Lagoon Shines in Spectacular Views from Very Large Telescope (Video)

A pink lagoon glows in the Milky Way. New photos taken by a telescope in Chile put the Lagoon Nebula — a giant cloud of gas and dust located 5,000 light-years from Earth — on rosy display.
The Lagoon Nebula (also called Messier 8) is about 100 light-years across and harbors young stars that shine brightly in the image, according to European Southern Observatory officials. The VLT Survey Telescope in Chile captured the picture, taken as part of a sweeping set of surveys designed to unlock mysteries of the universe. You can watch a video flythrough of the new Lagoon Nebula image from ESO, based on the new VLT telescope images.
"The surveys are addressing many important questions in modern astronomy," ESO officials said in a statement. "These include the nature of dark energy, searching for brilliant quasars in the early universe, probing the structure of the Milky Way and looking for unusual and hidden objects, studying the neighboring Magellanic Clouds in great detail, and many other topics.

"History shows that surveys often find things that are unexpected and these surprises are crucial for the progress of astronomical research," ESO officials added.
The Lagoon Nebula gets its name from a lagoon-shaped dust trail that winds through the glowing gas, and this isn't the first time ESO has imaged it. The observatory's Visible and Infrared Survey Telescope for Astronomy captured the nebula in stunning detail in infrared light, giving the cosmic wonder a different kind of glow.
A wider view of the Lagoon Nebula and its surroundings reveals other nebulas in a lush patch of sky. The Lagoon Nebula glows orange in the middle of the image, and the Trifid Nebula at the top of the picture and other nebulas glow with the central nebula as well.

ESO has also imaged the Lagoon Nebula before, looking at it in infrared light with its Visible and Infrared Survey Telescope for Astronomy in Chile.
The new images are part of one survey, yet there currently 11 public sky surveys in process using ESO telescopes. ESO officials have also released a zoomable version of the huge Lagoon Nebula image here: http://www.eso.org/public/images/eso1403a/zoomable/
ESO is operated by 15 different countries and is the most productive ground-based astronomical observatory in the world, according to ESO officials.
