“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.
“the size and age of the cosmos are beyond ordinary human understanding.
lost somewhere between immensity and eternity is our tiny planetary home.”
The one moment when 99% of the world’s population can see the sun
For a single minute at 7:15am, EST, on Friday, July 8, 99% of the world’s population was (7.688 billion people) either in sunlight or twilight and could simultaneously spot the sun in the sky. It’s a minute in time that only happens once a year. The only countries not under sun in that minute were New Zealand, Australia, Papua New Guinea, and Antarctica.
It’s hard not to see, but admittedly if someone wasn’t watching for the phenomenon that unfolded Friday morning, they could have definitely missed it. This does call into question what it means to be seeing the sun. According to the website timeanddate.com, while the claim is technically true, the number of people perceiving sunlight is a bit lower – about 93% of the world’s population.
“three things cannot be long hidden: the sun, the moon, and the truth.”

On an eight-day flight aboard the Space Shuttle Endeavour in 1992, AAAS member Mae Carol Jemison became the first African American woman to travel in space. Happy International Day of Women and Girls in Science!
Mae C. Jemison, born on this day in 1956, has a few firsts to her name: She was the first woman of color in space, as well as the only real astronaut to have served on the U.S.S. Enterprise, where she portrayed a lieutenant on an episode of Star Trek: TNG.
“we inhabit a universe that is characterized by diversity.”
