James Webb Telescope's first discoveryArt then science.

Art then science. Just over a week after NASA released the first James Webb Space Telescope photographs. 

Astronomers believe they have identified the oldest galaxy ever imaged—one going back 13.5 billion years, or 300 million years after the Big Bang.

As the universe expands, light's wavelength stretches into the red spectrum, measuring a galaxy's age. 

The redder the image, the more stretching & the farther—& older—the object. 

A team led by Rohan Naidu of the Harvard Center for Astrophysics found a galaxy with a shift at 13.5 billion years. 

Naidu told France 24 that they may be seeing the furthest starlight ever. 

The next step is peer review, which should validate their discovery. Galaxy is little. 

This 3,000 to 4,500 light-year-wide galaxy contains a billion stars. 

Our Milky Way spans 100,000 light years & contains 200 billion stars. 

Seeing anything 13.5 billion light years away is like seeing it 13.5 billion years ago. The little, old galaxy would have joined with others to produce a huge mass.
