✨ A new photo from the James Webb Space Telescope shows the Pillars of Creation — made famous by the Hubble Space Telescope — in vivid detail like never before.
Just compare JWST's photo (left) to Hubble's 2014 version. trib.al
The Pillars of Creation are a small part of the Eagle Nebula, a part of space where dense gas and dust birth new stars, about 6,500 light-years from Earth. axios.com
The pillars in this view of the nebula are made of interstellar dust and gas that feed star formation.
Bright red globes just outside of that dust are newly-formed stars and the squiggly red areas are caused by material being blasted out from those temperamental, baby stars.
When JWST image processors open photos sent back to Earth by the telescope, they essentially look black. axios.com
The JWST peers out into the universe primarily in infrared light — a part of the electromagnetic spectrum our eyes can't see — but it's so sensitive that it can tell the difference between various infrared bands. axios.com
Image processors assign those bands colors that the human eye intuitively understands. Red is used for longer infrared wavelengths and blue for shorter, allowing scientists to represent the structures in an accurate way. axios.com
