The space telescope's findings challenge the notion of a galaxy brimming with life.

Individual space telescopes, like Hubble and JWST, revolutionized our knowledge of the Universe. What if we had an array of them, instead?

Like humans, stars die. The James Webb Space Telescope's early images already give us a lot of information about how this happens.

Size matters, but it's not the only thing.

On July 12, 2022, JWST will release its first science images. Here are 5 ways the telescope's findings could change science forever.

Air currents in our atmosphere limit the resolving power of giant telescopes, but computers and artificial stars can sharpen the blur.

Each of our three nearest stars might have an Earth-like planet in orbit around it. Here's what we'll learn when we finally observe it.

It's a radical but plausible idea.

It is a story with nebulous beginnings and no discernible end.

The asteroid is expected to come within 140,000 miles of Earth — well inside the moon’s orbit.

The Universe isn't as "clumpy" as we think it should be.

Humanity's newest, most powerful space telescope is performing even better than predicted. The reason why is unprecedented.

NASA has finally chosen which flagship mission, like Hubble and JWST, will launch in ~2040. Detecting alien life is now a reachable goal.

If there are human-sized creatures walking around on other planets, would we be able to view them directly?

Hubble revolutionized astronomy more than once. Here's what we can expect from the James Webb Space Telescope.

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 no other galaxies in its vicinity for ~100 million light-years in all directions, it's as isolated and lonely as a galaxy can be.

A history of injustice and the greatest natural location for ground-based telescopes have long been at odds. Here's how the healing begins.

With infrared capabilities and image sharpness far beyond Hubble's limits, JWST looked at Hubble's deepest field, revealing so much more.

Astronomers have been looking for radio waves sent by a distant civilization for more than 60 years.

After years of analysis, the Event Horizon Telescope team has finally revealed what the Milky Way's central black hole looks like.

It was supposed to have a 5.5-10 year lifetime, and take 6 months to calibrate. It's performing better than anyone anticipated.

When we started imaging the Universe with Hubble, every star had four "spikes" coming from it. Here's why Webb will have more.

Along with gravitational lensing and ALMA's incredible long-wavelength spectroscopy, JWST is reshaping our view of the early Universe.

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

The James Webb Space Telescope is about to begin science operations. Here's what astronomers are excited about.

An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.

Hubble showed us what our modern day Universe looks like. JWST's big goal was to teach us how the Universe grew up. Here's where we are now.

Temperatures in the Sun's core exceed 10 million degrees Celsius. But how on Earth did we actually come to know that?

With a telescope at just the right distance from the Sun, we could use its gravity to enhance and magnify a potentially inhabited planet.
