The James Webb Space Telescope has once again pushed the boundaries of space exploration. It detected a distant galaxy that formed only 290 million years after the Big Bang. Named JADES-GS-z14-0 this galaxy is a mere 2% of the age of the Universe ...

Distant galaxies, Twinkling in the night sky, Mysteries untold

Distant galaxies, Twinkling in the night sky, Mysteries untold

The James Webb Space Telescope is a joint endeavour of US, European and Canadian space agencies which was launched in 2021. Its mission is to see farther across the cosmos and further back in time than any other astronomical tool.

Its latest discovery, JADES-GS-z14-0 is a
testament to its capabilities

This distant galaxy, located next to another galaxy, but far behind it has shattered the previous record. Observed only 290 million years after the Big Bang. To put this into perspective, the Universe is estimated to be 13.8 billion years old. Making this galaxy a mere 2% of its current age.

What makes this discovery even more intriguing is the size and brightness of JADES-GS-z14-0. Webb has measured the galaxy to be more than 1600 light-years across. Making it several billion times the mass of the Sun. This raises the question of how nature was able to create such a massive and bright galaxy in less than 300 million years. The presence of oxygen in this young galaxy is also a surprise, suggesting that multiple generations of massive stars had already lived and died before we observed it.

The word JADES in the galaxy's name stands for JWST Advanced Deep Extragalactic Survey. It is one of numerous observation programs using Webb to study the first few hundred million years of the Universe. This telescope was specifically designed to find the first stars to ignite in a nascent Universe. These giant objects are made only of hydrogen and helium and have short, but brilliant lives, creating the heavier elements seen in nature today.

Webb's discovery of JADES-GS-z14-0 offer
some valuable insights into the early stages
of the Universe

The presence of oxygen in this galaxy suggests it is already quite mature. This contradicts the theory that a majority of light in luminous galaxies is produced by gas falling into the central supermassive black hole. Instead, researchers believe light is generated by young stars, indicating that this galaxy has gone through multiple cycles of star formation.

This groundbreaking discovery highlights the importance of the James Webb Space Telescope in unravelling the mysteries of the Universe. With its advanced technology and capabilities, it has the potential to reveal even more distant and ancient galaxies.

These findings raise new questions and
challenges for scientists to explore!

The latest record-breaking discovery of JADES-GS-z14-0 by the James Webb Space Telescope has once again pushed the boundaries of space exploration. This distant galaxy. Observed only 290 million years after the Big Bang. Provides valuable insights into the Universe's early stages and poses new questions for scientists to unravel.

Webb continues to unveil the wonders of the cosmos and take us on a journey through the depths of our Universe.

Love, light & logic ...

About Steffi Lewis ...

Steffi Lewis 

Based in the charming village of Hanslope in Buckinghamshire, UK, I bring over 30 years of experience in web development. From creating my first website for the Open University in 1993, through being part of the dot com boom, to my explorations in SaaS and AI over the last few years, my journey has been a rich tapestry of web projects, big and small, both funded and bootstrapped.

Originally developed during the pandemic, at the start of 2025, I released the next iteration of YourPCM, version 2, which is all about 'Easy Contact Management for Small Business Owners'. Is it a CRM? Yes, but I don't call it that because people glaze over at the mention of such things. CRMs are boring, difficult to get to grips with, and it's a nightmare to get help when you need it. 

YourPCM is none of those things! It's simple to use, well-supported, feature rich and beautiful, right out of the box. It's available on a simple monthly subscription with no long-term tie-in. Book a demo or grab your own 14-working-day free trial and discover why YourPCM is all about easy contact management for small business owners. 

My head is in the cloud, my heart belongs to the web, and my soul is filled with such beautiful code 💗
