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

Summer Triangle: Deneb and Cygnus the Swan

10jul16_430

Tonight for July 18, 2014 

Tonight’s chart has you looking eastward at the famous Summer Triangle. Today, notice the star Deneb, the northernmost star in the Summer Triangle. Its constellation is Cygnus the Swan. In a dark country sky, you can see that Cygnus is flying along the starlit trail of the summer Milky Way.

The photo below is from Annie Lewis in Spain. She solved the problem of picking out the Summer Triangle from among many stars in the night sky by looking for the Triangle in the east soon after sunset. These three stars are, after all, among the brightest in the sky.

EarthSky Facebook friend Annie Lewis in Madrid, Spain captured this photo of the Summer Triangle, shortly after nightfall on a summer night. In fact, she said, the only stars visible to the unaided eye when she took the photo were the three in the Triangle. But her camera knew better. Thanks, Annie.
If it’s darker out, you might recognize the Summer Triangle by noticing that there is a cross within the Triangle. The constellation Cygnus is that cross. In fact, the constellation Cygnus is sometimes called the Northern Cross.
Okay, I’ve given you a lot of names here: Summer Triangle, Cygnus, Northern Cross.
Just remember, the constellation Cygnus the Swan contains the Northern Cross. The Cross is – more or less – just another way to see the Swan. The Northern Cross is what’s called an asterism, or recognizable pattern within a constellation. In this case, the pattern is the whole constellation, pretty much. At least, I never see them any differently.
Except for one thing. Deneb is at the top of the Cross, but at the tail of the Swan (the star name “deneb” always means “tail”). The little star Albireo is at the head of the Swan, but at the base of the Cross. Whew!
Our Summer Triangle series includes: Vega and its constellation Lyra Deneb and its constellation Cygnus: Altair and its constellation Aquila
