way out.

Standard
The first publicly released image from the James Webb Space Telescope, showing countless galaxies and multiple arcs where the combined gravity of those galaxies magnifies light from background objects, bringing even more distant galaxies into view.  NASA
NASA Administrator Bill Nelson described the image to President Biden, saying all the stars and galaxies it encompassed were located in an area of space the size of a grain of sand held at arm’s length by someone standing on Earth.

“We’re looking back more than 13 billion years,” he said. “That light that you are seeing has been traveling for over 13 billion years, and by the way, we’re going back farther. This is just the first image. They’re going back about thirteen-and-a-half billion years. And since we know the universe is 13.8 billion years old, we’re going back almost to the beginning.”

NASA plans to release additional “first light” images Tuesday, photos designed to showcase Webb’s ability to chart the details of stellar evolution, from starbirth to death by supernova, to study how galaxies form, merge and evolve and to probe the chemical composition of atmospheres around planets orbiting other stars.

This initial Webb deep field released Monday promises to rewrite the astronomy books yet again, providing the data needed to fill in many of the major gaps in the history of the universe, perhaps even providing the framework to determine when —  and how —  the first massive stars formed, exploded and seeded the cosmos with the heavy elements that make life possible.

lost somewhere between immensity and eternity is our tiny planetary home.”

heading out on a rainy day

to explore, discover things, and learn

in the much larger classroom of the universe.

tiny.

Standard

we are so tiny

 the size our worries should be

nothing in the scheme

“i believe everyone should have a broad picture of how the universe operates and our place in it.

it is a basic human desire.

and it also puts our worries in perspective.”
