Pictures in Science
They say a picture is worth a thousand words. I believe this is particularly true when it comes to science. What better way to get a non-scientific audience interested in the newest scientific discovery or technological innovation than through a captivating photograph without all the unintelligible technical jargon?
This is the Hubble Ultra-Deep Field.
This image was composited from data collected by the Hubble Space Telescope while it was aimed at a relatively modest portion of the night sky from September, 2003 until January, 2004. Those aren’t stars in the picture, every smudge and smear of light is an entire galaxy. In this picture alone, there are over 10,000 galaxies, each galaxy possibly containing anywhere from 10 million to a 100 trillion stars. As recent planet hunting research in our own Milky Way Galaxy has unveiled, it is believed that many of these star systems are also home to extrasolar planets. Let’s not forget that this is just one tiny fraction of the night sky. The observable universe is believed to contain over 100 billion galaxies. Daaang.
It’s pictures like these that really help you put things into perspective.
