A swoosh in space: Merry Christmas from Hubble


A swoosh in space: Merry Christmas from Hubble


The NASA/ESA Hubble Space Telescope celebrates the holiday season with a striking image of the planetary nebula NGC 5189.


Planetary nebulae represent a final brief stage in the life of a star like the Sun. While consuming the last of the fuel in its core, the star expels a large portion of its outer regions, which then heats up and glows brightly, showing intricate structures that scientists are still trying to fully understand. The structure visible within NGC 5189 is particularly dramatic, and Hubble’s image of the nebula is by far the most detailed yet made of this object [1].

Hubble has been a key tool for studying planetary nebulae for years, and many of its images have become famous. As well as being highly attractive, planetary nebulae tell us about the ultimate fate of the Sun, which will form such a nebula when it runs out of fuel in a little over five billion years.

These nebulae were named by astronomers studying them through early telescopes with little magnification and optics that were far from sharp. The brightly coloured nebulae are often roughly spherical, and many appear green or blue like Uranus and Neptune, so their appearance evoked that of gas giant planets like those in the outer Solar System.

Many of them do indeed look somewhat planetlike, but NGC 5189 certainly does not: the nebula forms a dramatic reverse S-shape.

Looking at the detail of Hubble’s image, possible thanks to Hubble’s very high resolution, the nebula shows a series of dense knots in the clouds of gas. The gas and radiation flowing out from the dying star carves out shapes in the clouds, forming glowing bow-wave-like patterns towards the centre of the nebula.

The knots in NGC 5189 are a reminder of just how vast the planetary nebula is. They might look like mere details in this image, but each and every one is a similar size to the entire Solar System.

The star at the centre of the nebula, a dense white dwarf, is far too small to see as anything other than a point of light, even though it is roughly the size of the Earth.

The overall shape of NGC 5189 can counterintuitively tell us about what is happening on very small scales around the tiny central star. NGC 5189’s shape is reminiscent of a lawn sprinkler, with matter being expelled from the star, which is wobbling as it rotates.

Similar structures have been seen before, especially in planetary nebulae with binary stars at their centres. This is also a likely explanation for the structure of NGC 5189, though to date, only one star has been found at the nebula’s centre.

Smart Brabus E-Bike







Το Smart Brabus e-bike έκανε το ντεμπούτο του στην Έκθ
Smart Brabus E-Bike

εση Αυτοκινήτου της Γενεύης το 2012 αυτό το μήνα. Έχει ένα κομβικό σημείο 500 watt κινητήρα, αρκετή ενέργεια για να χτυπήσει περίπου 25 μίλια/ώρα.

Αυτό είναι διπλή η δύναμη του τακτικού έξυπνο ποδήλατο που έχει πολύ κάτω από κινητήρα 250 watt κινητήρα κόμβο.

Μοιάζει με το έξυπνο θα έρθει με ένα ταμπλό του αυτοκινήτου bionx με ένα κατά παραγγελία iphone κάτοχος προστέθηκε στις. Η bionx συστήματα είναι ένα ευρέως διαθέσιμο πεντάλ βοηθήσει sytem, ​​η οποία τροφοδοτείται ελαφρά και αυτόματα προσθέτει δύναμη στο ρυθμό αναβάτες χωρίς τη χρήση του γκαζιού. Είναι όμως ως ένα wimpy σύστημα e-bike κύκλους. Στα 500 watts, αυτό το έξυπνο ποδήλατο έχει δύο φορές την ισχύ του Smart απόθεμα, να πάρει αυτό το ποδήλατο σε πάνω από 20 μίλια/ώρα ίσως 25 μίλια/ώρα.

Μοιάζει η Brabus χρησιμοποιεί το BionX PL500 σύστημα, το οποίο μπορεί να χρησιμοποιηθεί με γκάζι ή πεντάλ βοηθήσει και προσθέτει επίσης αναγεννητική πέδηση, ένα δύσκολο επίτευγμα με ένα κινητήρα κόμβο.





Αυτό το ποδήλατο μοιάζει με μια σοβαρή προσφορά e-ποδήλατο με ζάντες έθιμο του άνθρακα γίνεται για ένα κινητήρα κόμβο και δισκόφρενα. Το ποδήλατο έχει επίσης μια γλυκιά σύστημα ιμάντα μετάδοσης κίνησης.

Στόχος Smart με αυτό το ποδήλατο είναι να απελευθερώσει με την Brabus ηλεκτρικό αυτοκίνητο με το ίδιο χρώμα με την ιδέα του περισσότερο στυλ, περισσότερη δύναμη, περισσότερο και αποκλειστικότητα. Το σύνθημα για την Brabus γραμμή είναι "πράσινη καρδιά και την ψυχή μαύρη".

Η Brabus ηλεκτρικό ποδήλατο θα αρχίσει να πωλείται αργότερα αυτό το έτος. Τιμολόγηση δεν έχει κυκλοφορήσει ακόμα, αλλά υποψιαζόμαστε με βάση τις τιμές της τακτικής έξυπνο e-bike, αυτό θα πρέπει να λιανικής σε περίπου $ 5.000.

AGIA SOFIA scares THEM TOURKOUS


AGIA SOFIA scares THEM TOURKOUS

From the first moment that Constantinople fell to the Ottomans and Muhammad Fatih eisirthe riding the white horse of the Hagia Sophia, (where for some time, according to Turkish sources, remained motionless, looking with rapture the Pantocrator in the dome while impressive Capture scene and a Turkish film history), the great temple of Orthodoxy became the focus of various myths and legends circulated among the occupiers, causing an intense awe of this masterpiece of Orthodoxy now had surrounded the four Ottoman minarets .
     In recent years, however, some events focusing Hagia Sophia and culminating in an unexpected appearance in the summer of 2008 by Angelo in the dome, the Turks have created an intense atmosphere of distrust and fear of things to come. Resurfaced alongside all those legends that occasionally had shocked and had caused Muslims a typical phobia re emergence of orthodox Christian identity of the church and cosmogonic implications of this shocking event, despite the fact that operated until 1934 as a Muslim mosque.
     So last January, (01/20/2012), the large circulation Turkish newspaper, Sabah, presented a truly amazing tribute to the "Mysteries of the Holy Wisdom», (Ayasofya 'nın gizlemleri), which is reflected in a lively way that climate phobia paid their last Turks for what are hidden within the church and what promise to happen in the coming years.
     The first important element of this tribute is a slight phobia distinguished by the Turks to the hidden crosses, symbolic and otherwise, which are inside the church, but the floor plan as one can distinguish it from above. So much awe observed for the so-called (as the report attributes the Turks), "Cross of Saint Andrew the Apostle," who is known as the founder of the Church of Constantinople. So, according to Sabah, on the roof of the church is the Cross of St. Andrew in diagonal form, an important symbol not only lost in the centuries of Ottoman occupation, but dominates the whole symbolic significance. Also the "Cross of Justinian 'scares Turks and legends mention an ancient relic that is secret from Hagia Sophia and even from Egypt and has tremendous power. Generally, the structure of this great architectural masterpiece Orthodox, according to Turkish sources themselves, based on the Christian symbol of the Cross and this inspires awe and a subtle fear of the future restoration of Hagia Sophia in natural holder, ie Orthodox worship.
     But besides the crosses, and the Turks say other mysteries and scary for them to exist within the church. So, says the legend, it is known that after the conversion of the church into a mosque built in known Mihrab (Muslim place of prayer), which appeared on the eastern side of the church in the direction of Mecca. But the interesting thing is that according to the Turkish legends in front of the mihrab is buried a coffin made of gilt bronze. In this coffin lies the remains of Queen Sophia (obviously is identification with the Holy Wisdom). This queen Sophia and her coffin is, according to the Turkish legends, with a "mandate" that has passed through the centuries until today. This command indicates that there is no need to touch this casket or even touch it. If this happens, then, according to legend, this will cause the "uprising" of Queen Sophia and then a terrifying noise would jerk the whole structure of the temple causing seismic eschatological events that scare the Turks.
     But the legend of Queen Sophia has continuous. Thus, according to Turkish reports, the coffin is protected four archangels who are above the Dome of the church. The archangels are, they say they believe the Turks are Tzemprail, Michael, Israfil and Azrail. In fitting with the Turks, Tzemprail protects the Byzantine emperors, Michael the church from enemy attacks while Tzemprail and Israfil were the messengers of the events of the war in the Byzantine emperors. And these four archangels have regularly after the fall of Constantinople to protect the coffin of Queen Sophia of risk profane someone to open it and to bring about the Second Coming.
     Another important myth that Muslims say is the legend of the "Hidden Patriarch" resembling the Greek legend of the hidden priest. As the Turkish tradition, in the southern part of the temple there is a narrow corridor that leads to a very old and very mysterious arachniasmeni gate for which the legend mentions it as the "Gate Closed". According to Turkish reports, when Muhammad entered the Fatih in Istanbul Greek Orthodox Patriarch, the latter together with the attendants had assumed in this liturgy. Once the Ottoman hordes invaded the church, the Patriarch and all his entourage entered into the gate that closed and then lost while the gate was sealed and no one ever dared to open. Every year at Resurrection Orthodox Christians in front of the gate, as the Sabah state characteristics are shown .... red eggs! The legend is complemented by the prophecy that scares the Turks, that when the gate is opened, the temple will be heard again Christian Greek Orthodox chants so scared and alone in the idea of ​​opening this mysterious portal.
     The Turkish newspaper reports and the mystery of the underground tunnel that is centrally located inside the temple. As mentioned, this point there is a passage that leads to a large tunnel. In this tunnel, as the Turkish newspaper, leads to the Princes' Islands and even to the island first. The mystery of the Turks is how this tunnel was constructed and what role he played in the long history of the church.
     Mystery of the Turks is the large footprint of a large animal foot, maybe elephant is on the southwest side of the dome while here and have become some eschatological stories. Under the Turks the impression this is the horse of Mohammed the Conqueror, but the question is how the horse stepped on at this point that is up toward the dome.
     Large awe creates the Turks, as the Sabah and various mosaics that have emerged with all the magnificence of the past decades in the church of Hagia Sophia in Istanbul, despite the fact that the Muslim religion considers sin as the representation of a person associated with religious events. Special awe their causes known mosaic depicting the Virgin Mary having Jesus and John the Baptist on the right and left. The Turks have called the features "Mosaic Revelation" and the symbolism makes the eschatological significance is strong among Muslim Turks.
     Also special mention is made for mosaics depicting famous Byzantine emperors, as John Comnenus with Jesus Christ and Emperor Constantine duel with the Empress Zoe. All these depictions cause intense awe as this whole orthodox Christian magnificence and inner strength that manifest these mosaics have spawned several legends about the eschatological symbolism. The symbols are related to the Turkish fears about returning to the surface and the power of the Holy Eastern Roman Empire with the blessing of Jesus Christ himself.
