Looking deeply into space and time, two teams using NASA’s James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old.
The findings, published Wednesday in Nature, use data from the James Webb Space Telescope ’s infrared-sensing instruments to picture what the universe looked like 13.5 billion years ago—a time...
While this vast region contains about 100,000 galaxies, the visualization focuses on approximately 5,000 – with the nearest and more complex galaxies, shown in the beginning, located within a few billion light-years of Earth.
The James Webb Space Telescope found massive, mature galaxies inhabiting the universe so soon after the Big Bang that according to current theories they really shouldn't exist.
The 19 spiral galaxies newly imaged by the Webb Telescope. Older stars are clustered near the centers of the galaxies, while younger stars are farther out along the spiral arms.
Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest contain trillions of stars and can be more than a million light-years across. The smallest can contain a few thousand stars and span just a few hundred light-years.
Only NASA’s James Webb Space Telescope can deliver highly detailed scenes of nearby galaxies in a combination of near- and mid-infrared light – and a set of these images was publicly released today.
The James Webb Space Telescope has captured scintillating images of 19 spiral galaxies — and the millions of stars that call them home — in unprecedented detail never seen before by...
The James Webb Telescope (JWST or Webb) has unveiled hundreds of ancient galaxies that could be among the first members of the universe — a leap from only a handful that were previously known...
James Webb Space Telescope. Nasa's new super telescope reveals 10 times more galaxies like our own Milky Way in the early Universe.
