Από το εξαιρετικά μεγάλο στο απίστευτα μικρό. From the Extremely Big to the Incredibly Small

Το Παρατηρητήριο ακτίνων Χ Chandra της NASA – το κορυφαίο τηλεσκόπιο στον κόσμο που ανιχνεύει ακτίνες Χ από το διάστημα – χρησιμοποίησε εικόνες από το nikonsmallworld.com, για να συγκρίνει εικόνες του μικρόκοσμου με εικόνες του μακρόκοσμου, προβάλλοντας τις διαφορές και τις ομοιότητες μεταξύ μικροσκοπίας και της μακροσκοπίας. To explore, we need to keep our senses open. By developing new “eyesˮ for both the very big and the very small, scientists have opened windows of discovery via technology, science, and engineering. A new collaboration celebrates this spirit of exploration from some of the worldʼs most powerful telescopes to the impact of high-powered modern microscopes. This big versus small comparison lets us see the world and the universe around us like never before. It allows us to consider ideas like, what does the eye of a fruit fly have in common with the remains of an exploded star? What about a cell line and a planetary nebula? How do we capture images of things we canʼt see directly? The possibilities, to use a cliché, are infinite. This fall, NASAʼs Chandra X-ray Observatory — the worldʼs premier telescope that detects X-rays from space — has worked with images from Nikon Small World, a free microscopy imaging competition, to celebrate the similarities and differences between the micro and the macro.

Στο βίντεο που ακολουθεί θα δείτε εικόνες από τα πιο ισχυρά τηλεσκόπια σε αντιστοιχία με εικόνες από τα ισχυρότερα σύγχρονα μικροσκόπια.

Each image of M51 is about 52,000 across by 87,000 light years tall.

Τα κύτταρα μιας φρουτόμυγας μοιάζουν με σύμπλεγμα γαλαξιών, το ορυκτό αχάτης με την επιφάνεια του πλανήτη Δία, ο θάνατος του κυττάρου με τον θάνατο άστρου, η επιφάνεια του Ήλιου με νανοσωλήνες άνθρακα, το πόδι πασχαλίτσας με σύμπλεγμα άστρων, οι «τρίχες» φυτών με τις ηλιακές κηλίδες, άστρα που εκρήγνυνται με την διαίρεση των κυττάρων κ.ο.κ.
