A new measurement offers insights on the density of the mysterious force driving the Universe’s expansion.
When we started imaging the Universe with Hubble, every star had four “spikes” coming from it. Here’s why Webb will have more.
Stars are born, live, and die within the spiral arms of galaxies like the Milky Way. These 19 JWST spirals deliver unprecedented riches.
The James Webb Space Telescope viewed Neptune, our Solar System’s final planet, for the first time. Here’s what we saw, and what it means.
The first set of James Webb’s images blew us all away. In just 2 mere months, it’s seen highlights that no one could have predicted.
Archaeologists can learn how societies lived by studying what they left behind when they died. Astronomers are doing much the same thing.
Since dark matter eludes detection, the mission will target sources of light that are sensitive to it.
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
For thousands of years, humanity had no idea how far away the stars were. In the 1600s, Newton, Huygens, and Hooke all claimed to get there.
Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
You would think that with all our technology, like the James Webb Space Telescope, we would know how big the Universe is. But we don’t.
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here’s what to hope for.
From the tablets of the Babylonians to the telescopes of modern science, humans have always looked to the skies for fundamental answers.
There are billions of potentially inhabited planets in the Milky Way alone. Here’s how NASA will at last discover and measure them.
With a finite 13.8 billion years having passed since the Big Bang, there’s an edge to what we can see: the cosmic horizon. What’s it like?
With a new telescope on the horizon, we reflect on the best pictures of space that came before.
Thanks to time-traveling telescopes, we can see more about the Big Bang.

Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it’s funded, and soon.
To study the origin of the Universe, we could build a constellation of six expensive spacecraft — or we could just use the Moon.
Scientists can make substantial progress without fully understanding exactly what they’re doing.
The James Webb Space Telescope could help scientists learn about the cosmic dark ages and how they ended.
The James Webb Space Telescope has chosen 5 targets for its first science release. Here’s what we know on the eve of JWST’s big reveal!
A true scientific view of if, where, and when extraterrestrial life exists is within our grasp thanks to biosignatures and technosignatures.
With its very first deep-field view of the Universe now released, the James Webb Space Telescope has shown us our cosmos as never before.
The light from Earendel took 12.9 billion years to reach Hubble. The star is millions of times brighter than our Sun and 50 times as massive.
Should we be searching for life on other planets, or technology?
A deep dive into the chaotic journey of star formation.
JWST’s revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA’s Spitzer first, it wouldn’t have been possible.
