Many collaborations have used JWST to take deep-field images: some wider and some deeper than others. Here's how it can surpass them all.

30 years ago, we didn’t know other stars had planets orbiting them. Now, we may be on the verge of finding Earth’s Twin. Sara Seager explains.
The Universe formed stars, galaxies, and even galaxy clusters extremely early on in our cosmos. This new marvel is one more JWST surprise.
Just like animals, galaxies often have bizarre, unusual, or even unique properties. But finding many, all at once, really does raise alarms.

"In the process of mapping the heavens, it doesn't take long to realize the data problem they generated."
Our view of the world, the Universe, and ourselves can change with just one glimpse of what's out there. It's happened many times before.
Outer space begins just over 100 kilometers up, but what we can see extends for billions of light-years. Here's what all of it looks like.
Even in an expanding Universe, we expect both redshifted and blueshifted galaxies. But nearly every one we see is redshifted. Here's why.
The Sun often produces solar flares and coronal mass ejections, but a rare solar radiation storm made the 2026's first great auroral show.
With unprecedented resolution, wavelength sensitivity, and light-gathering power, JWST reveals our cosmos like no other observatory ever.
Gravitational lenses arise when foreground masses and background light sources properly align. Einstein rings are rare, but crosses abound.
The VENUS survey isn't about planets at all, but about finding multiply-lensed supernovae. The ambition? To save the expanding Universe.
US science is worth fighting for, but so are the science projects and scientists denied opportunities. Here are 4 paths all worth exploring.
Back in 1604, Johannes Kepler discovered the Milky Way's last naked-eye supernova. Here's how NASA's Chandra sees it over the 21st century.
The seeds of cosmic structure that were planted back during the Big Bang grew into the cosmic web we see today. What is it telling us?
Astronomer Lisa Kaltenegger spoke with Big Think about how "the colors of life" could leave detectable traces on distant planets.
Even the youngest galaxies are often dust-rich, even with very low levels of heavy elements. Nearby dwarf galaxy Sextans A explains why.
Astronomers have found starless gas clouds before, but Cloud 9 might be the most pristine one of all, with big lessons for cosmic history.
In a galaxy less than 300 million years after the Big Bang, oxygen's presence abounds. That's expected; its absence would truly be profound.
There will always be "wolf-criers" whose claims wither under scrutiny. But aliens are certainly out there, if science dares to find them.
If you can identify a foreground star, the spike patterns are a dead giveaway as to whether it's a JWST image or any other observatory.
The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.
While humanity has been skywatching since ancient times, much of our cosmic understanding has come about only recently. Very recently.
Our Universe doesn't just expand and cool, but the expansion itself is accelerating. Can stars form under such structure-erasing conditions?
Earth orbits the Sun while spinning on its tilted axis, with two annual occasions marking that maximal tilt. That's where solstices arise.
With the observation of SN 2025wny, a lensed superluminous supernova, astronomy's future comes into sharp, exciting focus.
It takes a wide variety of processes in the Universe to make all the elements that populate space today. We're still discovering new ones!
Some vital, key ingredients must be in place for the Universe to make more matter than antimatter. The LHC took us one step closer in 2025.
Finding alien Earths requires seeing Earth-sized planets at Earth-like distances from Sun-like stars. A new discovery completes the roadmap.
With a waning Moon and a denser-than-ever debris trail, 2025's Geminids might be the year's best meteor shower, and 2026's could be amazing.
