A new hypothesis suggests that the universe may be twice as old as we had believed. Observations from the James Webb Space Telescope provide new information on the rate of the universe’s expansion.
A phenomenon called gravitational lensing can help astronomers observe faint, hard-to-see galaxies.
The universe used to be filled with a hydrogen fog, before early stars and galaxies burned through the haze. Astronomers are studying galaxies that tell them about this period in the early universe.
NASA’s missions have inspired generations of young people to pursue the sciences.
Both Stephen Alexander’s elementary teachers and televised NASA missions throughout the ‘60s influenced his journey into science. He recounts NASA’s legacy, 65 years after the agency’s inception.
A light, cheap space telescope design would make it possible to put many individual units in space at once.

Space telescopes are limited in size due to the difficulties and cost of getting into orbit. By revamping an old optical technology, researchers are working on a lightweight and thin telescope design.
Black holes and other massive objects create ripples in spacetime when they merge.

Since ancient times, the stars have been set to music. Modern technology now enables scientists to convert images of space into real compositions.
The James Webb Space Telescope began sending its first images back to Earth in the summer of 2022.

NASA has been gaining momentum in recent years as investment into space has ramped up in the US. In 2022, missions dealt with the farthest, closest, hottest and coldest conditions in the universe.
The Carina star-forming region imaged by the JWST.
A year on since the historic launch of the most powerful infrared telescope in human history, we admire and explore some of the best images it delivered in 2022.
The James Webb Space Telescope is providing astronomers with images and data that reveal secrets from the earliest era of the universe.
It has been one year since the launch of the James Webb Space Telescope and six months since the first pictures were released. Astronomers are already learning unexpected things about the early universe.
Astronomers have unpacked the mystery of how one star’s death created the nebula NGC3132 – never before seen in such detail.
