The candy-dish appearance of this high-tech astronomical mirror is striking.
Made of a special glass ceramic material called Zerodur, it actually measures 2.7 meters across.
The transparent surface has not yet received a reflective coating, so the weight-reducing internal honeycomb structure is visible with attractive blue and yellow tints provided by a protective tarp and background lighting.
Recently unveiled, the telescope mirror is destined to fly on the Stratospheric Observatory For Infrared Astronomy (SOFIA).
Since water vapor in Earth's troposphere tends to block infrared light, SOFIA will operate from a modified Boeing 747 jetliner at altitudes above 40,000 feet.
As the largest airborne observatory in the world, SOFIA will explore a host of cosmic environments including sites of star birth and death, the formation of distant solar systems, and black holes in active galaxies.
Hani ebe au gmeint. Aber hie und do schloht sie ebe glich überd Sträng. Wie goht da nur, sie isch doch di zueverlässigscht Zorgin, APOD-Kommentatorin und Forum-Sekretärin?
I has usegfunde, woni letschti wiedermol uf di erscht Metro ha wöllä. Zwüsched Vieri und Sechsi am Morge sind die wenigschte Zorger unterwegs, und genau denn loht sie amel ine bis nümä meh goht. Am Morge sind d'Zorger eh no nöd fit und merked nüt vo de Verzögerige und vereinzelte Fehler, und bis die denn mol de zweit Kafi gnoh hend isch halbi Zehni und d'Barbara isch wieder uf de Bei...
