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?
With LEDs bringing brighter nighttime lighting than ever before, and thousands of new satellites polluting the skies, astronomy needs help.
Like humans, stars die. The James Webb Space Telescope's early images already give us a lot of information about how this happens.
Without this genius optical trick, those gigantic telescopes aren’t any better than the one in your backyard
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.
It's a radical but plausible idea.
The asteroid is expected to come within 140,000 miles of Earth — well inside the moon’s orbit.
It is a story with nebulous beginnings and no discernible end.
The Universe isn't as "clumpy" as we think it should be.
On Saturday, October 14, a solar eclipse crosses North and South America. Here are 4 quick, easy, low-tech activities for everyone to enjoy!
NASA has finally chosen which flagship mission, like Hubble and JWST, will launch in ~2040. Detecting alien life is now a reachable goal.
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 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.
With infrared capabilities and image sharpness far beyond Hubble's limits, JWST looked at Hubble's deepest field, revealing so much more.
Hubble revolutionized astronomy more than once. Here's what we can expect from the James Webb Space Telescope.
If there are human-sized creatures walking around on other planets, would we be able to view them directly?
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.
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.
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.
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.
It was supposed to have a 5.5-10 year lifetime, and take 6 months to calibrate. It's performing better than anyone anticipated.
