Gambar 9 billion pixel yg menunjukkan 84 million bintang milky way apabila di zoom..
Subhanallah..Astronomers have used a giant dust-busting telescope in Chile to zoom in on the heart of our Milky Way galaxy and capture more than 84 million stars. The international team used Europe’s VISTA survey telescope to produce an incredibly detailed mosaic formed from thousands of separate images and made up of nearly nine billion pixels.
VISTA’s camera is especially sensitive to the warmth of infrared light which allowed it to record many stars that would normally be hidden behind vast clouds of dust and so invisible in optical light. The image is so large (108,200 by 81,500 pixels) that if it were to be printed at the resolution of a typical book, it would be nine metres long and seven metres high. But it wasn’t just taken as a pretty picture, of course.
