More than two years after JWST began science operations, our Universe now looks very different. Here are its biggest science contributions.

The JWST’s observations of well-developed galaxies early in universal history may coincide with accepted astronomical theory after all.

Unexpected images of galaxies from the James Webb Space Telescope do not disprove the Big Bang. There are other likelier explanations.

Astronomy’s roots rest in the very origins of humanity. We have always looked to the skies for answers. We are starting to get them.

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.

Once science operations begin for James Webb, we’ll never look at the Universe the same way again. Here’s what everyone should know.

Hubble’s deepest views of space revealed fewer than 10% of the Universe’s galaxies. James Webb will change that forever.

The James Webb Space Telescope finally could answer the age-old question of whether we are alone in the universe.

From exoplanets to supermassive black holes to the first stars and galaxies, Webb will show us the Universe as we’ve never seen it before.

Hubble, our greatest space-based observatory today, is just the beginning. The Hubble Space Telescope has been astronomy’s most revolutionary observatory in history. The stars and galaxies we see today didn’t […]

An artist’s impression of what the fully-deployed James Webb Space telescope will look like from the perspective of an observer on the ‘dark’ (non-Sun-facing) side of the observatory. (NORTHRUP GRUMMAN) […]

The successor to Hubble is almost ready for launch. It’s really coming this year, too! NASA’s James Webb Space Telescope, originally proposed in the 1990s, is finally slated to launch later […]

We’ve come fantastically far in our understanding of the distant Universe. Here’s how we’ll go even farther. Sometime in 2021, NASA’s James Webb Space Telescope will launch, deploy, and begin science […]

Good news for space exploration?

Even if it can’t detect them directly, we’ll learn the answer. Here’s how. Perhaps the most revolutionary find of the past generation, when we think about the Universe beyond Earth, is […]

A live-blog event of an incredible public lecture by a scientist on the inside of James Webb’s team. “The [James Webb] telescope is basically designed to answer the big questions in […]

This week, Bill Nye the Science Guy weighs in on the reality of the timeless superhero wish, how not to break your legs while trying comic book moves, and the human virtues of Bruce Wayne and Peter Parker.

Why the biggest, most expensive NASA telescope ever is also the most important thing we’ve ever attempted. “Where there is an observatory and a telescope, we expect that any eyes […]

James Webb will grant a peerless gaze at the universe the likes of which we’ve never seen.

The space telescope has worsened NASA’s relationships with Congress, who felt duped by the exploding cost of the project. Still, the telescope may prove an amazing technical achievement.

The James Webb Telescope has become a political football since it, predictably, has run over time and budget. Why can’t N.A.S.A. and Congress do better financial planning?

Fearing budget cuts, N.A.S.A. chief Charlie Bolden told Congress that the next-generation space telescope has greater potential for discovery than the iconic Hubble Space Telescope.

Someday, we’ll look back and see a young galaxy forming stars for the first time. JADES-GS-z14-0, the farthest ever, isn’t early enough.

Our scientific instruments are constantly improving, revealing nature’s workings as never before. Without them, we’ll remain in the dark.

One of the most promising dark matter candidates is light particles, like axions. With JWST, we can rule out many of those options already.

The ultimate multi-messenger astronomy event would have gravitational waves, particles, and light arriving all at once. Did that just occur?

Seeking life beyond the Solar System, we first look to the closest star systems with Earth-like planets. Here’s why that’s not good enough.

Scientists just viewed one of the tiniest, most isolated, lowest-mass galaxies ever found with JWST. Despite all odds, it’s still growing.

Since mid-2022, JWST has been showing us how the Universe grows up, from planets to galaxies and more. So, what’s its biggest find of all?

The discovery of ultra-bright, ultra-distant galaxies was JWST’s first big surprise. They didn’t “break the Universe,” and now we know why.
