Nasa’s James Webb telescope is awesome beyond words.
The recent launch of this telescope, as a successor to Hubble, can see right back more than 13.5 billion years. The universe was formed 13.78 billion years ago. The reach of the James Webb telescope is therefore 98% (97.96) of the life of the universe. But the superlatives about this telescope are almost never-ending. For example it will, in time, be able to explore the tiny planetary worlds far, far away. We may in time see signs of life, as in water, vegetation, or industrialisation, connected with those planets.
The James Webb is in orbit some million miles away from Earth and will, in fact, be orbiting the sun.
One could go on and on speaking about this achievement but I will resist. I want to share a three things with you.
First the release of this early image and a portion of the associated text:
NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far. Webb’s First Deep Field is galaxy cluster SMACS 0723, and it is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared.
Webb’s image is approximately the size of a grain of sand held at arm’s length, a tiny sliver of the vast universe. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying more distant galaxies, including some seen when the universe was less than a billion years old. This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks. And this is only the beginning. Researchers will continue to use Webb to take longer exposures, revealing more of our vast universe.
Second, why is it named after James E. Webb (1906- 1992)? James Webb was NASA’s second administrator and known for leading Apollo, the series of lunar exploration programs that landed the first humans on the Moon. (A good Q&A is here: https://www.jwst.nasa.gov/content/about/faqs/faq.html )
Last thing to share is some music! ‘Floating in Heaven’ by Graham Gouldman and Brian May
It is indeed wonderful to be alive at this time!
You never felt the urge to build an observatory?

Tee, here! The best I have done is to stare at the night sky through a pair of binoculars! What is your night sky like down in Brazil, John?

Southern Hemisphere has great sky’s. Do you remember when you were out in the desert?

You mean the Australian outback? I am afraid that I don’t recall the night skies clearly. I do remember the night skies when sailing in the Mediterranean back in the late 80s and they were amazing.

It is wild when you get out of of all light pollution. I seriously want to go to visit the observatories in Atacama (Chile), and do some camping.

I hope you do, and soon. Plus take a camera and tripod and share your photographs with me!
