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.

interacting galaxy in four different types of light: optical from Hubble
(green), X-rays from Chandra and ultraviolet from GALEX (blue), infrared from
Spitzer (red) and composite in bottom right. Each image of M51

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. Δείτε το βίντεο:
