Shedding Light on the Cosmic Skeleton

Posted in ASTRONOMY NEWS with tags on November 3, 2009 by Neptune

Astronomers have tracked down a gigantic, previously unknown assembly of
galaxies located almost seven billion light-years away from us. The
discovery, made possible by combining two of the most powerful
ground-based telescopes in the world, is the first observation of such a
prominent galaxy structure in the distant Universe, providing further
insight into the cosmic web and how it formed.

This 3D illustration shows the position of the galaxies and reveals the extent of this gigantic structure. The galaxies located in the newly discovered structure are shown in red. Galaxies that are either in front or behind the structure are shown in blue.

This image, obtained with the Subaru Telescope, operated by the National Astronomical Observatory of Japan was used by a team of astronomers, led by Masayuki Tanaka from the European Southern Observatory (ESO), to uncover a gigantic, previously unknown assembly of galaxies located almost seven billion light-years away from us. This structure was confirmed by further observations made using ESO’s Very Large Telescope and Subaru. It is the first observation of such a prominent galaxy structure in the distant Universe, providing further insight into the cosmic web and how it formed. The galaxies located in the newly discovered structure are shown in red. Galaxies that are either in front or behind the structure are shown in blue.

Astronomy-Astrophotography Site

Posted in ASTRONOMY NEWS, NEWS FROM GREECE on October 29, 2009 by Neptune

Το Site αυτό δημιουργήθηκε με μοναδική αιτία την αγάπη μου για τη φυσική και την αστρονομία. Η προσπάθεια για ενημέρωση και συμπλήρωση του Site είναι καθημερινή, και η δημιουργία των άρθρων γίνεται αργά, προσπαθώντας να γραφτούν σε απλή και όχι επιστημονική γλώσσα, για να είναι κατανοητά και από ανθρώπους που ασχολούνται ή που θέλουν να ασχοληθούν με την αστρονομία.

Στο Site θα βρείτε χρήσιμα πράγματα, όπως Χάρτες του ουρανού και διάφορα άλλα άρθρα και Links που θα σας βοηθήσουν στην παρατηρησιακή αστρονομία αλλά και στην αστροφωτογράφηση.

Σκοπός της ιστοσελίδας (όπως και του Blog) δεν είναι το οικονομικό κέρδος αλλά η διάδοση και η κατανόηση της Αστρονομίας με όσο πιο απλό τρόπο γίνεται. Κάθε είδους σχόλια ή παρατηρήσεις, στο μέτρο της ευπρέπειας, είναι αποδεκτά και καλοδεχούμενα.

Εύχομαι να βρείτε το Site αρκετά ενδιαφέρον και ακόμα καλύτερα θα είναι να βρείτε αυτό το οποίο ζητάτε ή αναζητάτε.

Το όνομά μου είναι Κωνσταντίνος Ράμμος και έχω σπουδάσει  «Ηχοληψία» και  «Τεχνικός Τεχνολογιάς Internet», ενώ παρακολουθώ στο «Ελληνικό Ανοικτό Πανεπιστήμιο» τη «Σχολή Θετικών Επιστημών & Τεχνολογίας» το τμήμα «Σπουδές στις Φυσικές Επιστήμες».
