Ursa Major over #Konitsa, #Epirus, #Greece
The constellation Ursa Major contains the group of stars commonly called the Big Dipper. The handle of the Dipper is the Great Bear's tail and the Dipper's cup is the Bear's flank. The Big Dipper is not a constellation itself, but an asterism, which is a distinctive group of stars. Another famous asterism is the Little Dipper in the constellation Ursa Minor.
If you live in the Northern Hemisphere, you can use the Big Dipper to find all sorts of important stars:
If you draw an imaginary line from Merak through Dubhe out of the cup of the dipper (see the picture above) and continue five times as far as Dubhe is from Merak, you will arrive at Polaris, the North Star.
Now draw an imaginary line along the handle of the dipper and continue the arc across the sky. Eventually this will lead you to the very bright star, Arcturus in the constellation Boötes. If you continue the arc further, you will reach Spica in Virgo. You can remember this by saying "Arc to Arcturus and Speed to Spica."
If you follow the other two stars in the cup of the dipper (Megrez and Phecda) down below the cup, you will get to Regulus.html, the brightest star in Leo.
According to some Native American legends, the bowl of the Big Dipper is a giant bear and the stars of the handle are three warriors chasing it. The constellation is low in the sky in autumn evening sky, so it was said that the hunters had injured the bear and its blood caused the trees to change color to red.
Although the whole of Ursa Major is difficult to see without very dark skies, the Big Dipper is one of the most recognizable patterns in the northern sky. In other cultures it was identified as a wagon or cart, a plow, a bull's thigh, and (to the Chinese) the government.
The Big Dipper was also a very important part of the Underground Railroad which helped slaves escape from the South before the Civil War. There were songs spread among the slave population which included references to the "Drinking Gourd." The songs said to follow it to get to a better life. This veiled message for the slaves to flee northward was passed along in the form of songs since a large fraction of the slave population was illiterate.

Seashore with table and boat
Kastellorizo is (with the exception of the nearby islet of Strongýli) the easternmost Greek island and is situated in the Eastern Mediterranean. It lies about 2 kilometers from the Anatolian coastal town of Kaş, more or less half-way between Rhodes and Antalya. Cyprus is about 280 km (170 mi) to the south-east. It is six kilometers long and three kilometers wide, with a surface of 9.2 km². It has a triangular shape, and is oriented from NE to SW. The island features three capes: Agios Stefanos (north), Nifti (east) and Pounenti (south west); between the first two there is a wide and accommodating bay, the island's main harbor, where one finds the only town on the island. Cape Agios Stefanos, the nearest to Anatolia, is 2250m south of the modern Turkish town of Kaş (Greek: Andífli, the Ancient Greek City of Antiphéllos). Cape Nifti lies some greater distance from the Anatolian coast. The island is mountainous, with high and steep coastlines, which become more difficult to access moving west. The soil is composed of limestone, and produces only small amounts of olives, grapes and beans.
On the island there is no source of drinking water.
The Municipality of Megísti includes the populated offshore islands of Ro (pop. 15) and Strongýli (9) as well as several uninhabited islets. It has a total land area of 11.987 km².

Αλεξίου Χάρις - Έχει Πανσέληνο Απόψε
Στην μέση ενός μικρού σπιτιού, που `χω νοικιάσει
το γέλιο ενός μωρού παιδιού με έχει αγκαλιάσει.
Τα ζήτησα όλα απ’ τη ζωή μου, τα πλήρωσα με την ψυχή μου
να έχει ένα τόπο η καρδιά πριν να γεράσει.
Μα έχει πανσέληνο απόψε κι είναι ωραία
είναι αλλιώτικη η σιωπή χωρίς παρέα.
Δεν νιώθω θλίψη, μα μου’χει λείψει
το κοριτσάκι αυτό που αγάπησες τυχαία.
Δεν νιώθω θλίψη, μα μου `χει λείψει
το λάγνο ψέμα σου που τα `κανε όλα ωραία.
Είναι σκληρό για μια γυναίκα να `ναι μόνη
στο λέω τώρα που η αλήθεια δεν θυμώνει.
Όση και να `ναι η δύναμή μου, θέλω έναν άνθρωπο μαζί μου
Η μοναξιά στήνει παγίδες και πληγώνει.
Μα έχει πανσέληνο απόψε κι είναι ωραία
το σπίτι μου έρημο να κάνουμε παρέα.
Δεν νιώθω θλίψη, μα μου `χει λείψει
το κοριτσάκι αυτό που αγάπησες τυχαία.
Δεν νιώθω θλίψη, μα μου `χει λείψει
το λάγνο ψέμα σου που τα `κανε όλα ωραία.

Enhanced Color Mercury Map
This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER's primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury's surface. This specific color combination places the second principle component in the red channel, the first principle component in the green channel, and the ratio of the 430 nm/1000 nm filters in the blue channel.
The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.

Juneau Bering Sea Airship Flight
The Greenpeace thermal Airship A.E. Bates takes to the skies over Juneau, Alaska on June 8, 2013 in an effort to protect Alaska's Bering Sea. The airship was sporting a 75 foot whale-themed banner urging Alaska residents and the North Pacific Fishery Management Council to help protect the "grand Canyons of the Sea."

Light-Emitting Bubbles
Scientists Investigate Light-Emitting Bubbles
Michael D. Wheeler
LOS ANGELES --
What do sound waves, water bubbles and photons have in common? They are the primary players in sonoluminescence, a phenomenon in which the tiny bubbles created by intense acoustic fields in water emit light as they collapse.
It also spurred Gary A. Williams from the University of California and his colleagues to conduct experiments in sonoluminescence. They focused on creating single-bubble luminescence in alcohol and nitrogen at cryogenic temperatures, but they found it difficult to trap the bubbles. They tried another approach: using focused laser pulses to induce cavitation.
In experiments that they described in the May 21 issue of Physical Review Letters, the researchers created bubbles in water with 6-ns, 600-mJ pulses from an Nd:YAG laser. The water absorbed the energy from the focused pulse, creating a bubble that expanded to 2 mm in diameter before it collapsed.
The key to analyzing the luminescence was a Roper Scientific spectrometer with intensified CCD readout capabilities. "The CCD allows us to record a range of 200 nm of the spectrum on each shot," Williams explained. "Because the luminescence is only about 108 photons from each bubble, the intensifier stage of the CCD proved crucial in boosting the signal."
The bubbles displayed a molecular OH* band at 310 nm, which approximates a 7800-K blackbody spectrum. This suggests a strong connection between the emission from single and multiple bubbles, because the same molecular band is observed in the latter.

Dandelion Sunset
The common name dandelion (/ˈdændɨlaɪ.ən/ dan-di-ly-ən, from French dent-de-lion, meaning "lion's tooth") is given to members of the genus, and like other members of the Asteraceae family, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a floret. Many Taraxacum species produce seeds asexually by apomixis, where the seeds are produced without pollination, resulting in offspring that are genetically identical to the parent plant
