NASA’s James Webb Space Telescope (JWST) has outdone its predecessor, the Hubble Space Telescope, by retaking the iconic Pillars of Creation shot from about 25 years ago.
This highlights the difference between observations in the visible part of the Electromagnetic spectrum (Hubble) and observations from the infrared part (JWST). It also demonstrates the enormous increase in resolving power achieved by JWST’s much larger mirror.
I did a presentation for a physics class in early 2004 on what was then named the Next Generation Space Telescope (JWST) and it was, then, slated to launch by the end of that decade. I was angry when I read, in 2011, that the launch date had been slipped SEVEN YEARS, and disheartened when it delayed more until finally launching late last year. All I’m going to say now is the axiom, “Anything worth having is worth waiting for.” This is WOW on steroids.
