“We are made of star stuff.” When the astronomer Carl Sagan said that famous line, he was reminding people that much of the matter of our bodies was created within the stars long ago. He wanted people to know we are marvelous and our story is, too.
Humanity’s story took a new and interesting turn when we traveled back in time 13 billion years. After over two decades of design and planning, on Monday NASA released the first image from the James Webb Space Telescope, which revealed the deepest infrared view of the universe, ever. This new deep-field image is much more detailed than earlier images captured by the Hubble telescope. Once again we are gawking in awe at the universe.
While there are a few interloper stars in the photo, nearly every dot in the image is a galaxy. For a sense of scale, if you could hold a grain of sand at arm’s length up to the sky, that speck is the size of the view. It is one minuscule sliver of our universe, filled with thousands of galaxies, each with billions or trillions of star systems and each of those with its own planets.
On Tuesday, NASA released even more images from the telescope, including views of the Carina and Southern Ring Nebula as well as notable clusters of galaxies.
