Stars are born, live, and die within the spiral arms of galaxies like the Milky Way. These 19 JWST spirals deliver unprecedented riches.
If our Milky Way were located in the Virgo cluster instead of the Local Group, chances are we'd already be a "red and dead" galaxy.
If there’s life lurking on the moons of Saturn and Jupiter, could our instruments even detect it?
Valles Marineris is the Solar System's grandest canyon, many times longer, wider, and deeper than the Grand Canyon. What scarred Mars so?
Astronomers claim to have found structures so large, they shouldn't exist. With such biased, incomplete observations, perhaps they don't.
Here in our Solar System, we only have one star: a singlet. For many systems, including the highest-mass ones, that's anything but the norm.
The pattern 1, 1, 2, 3, 5, 8, 13, etc., is the Fibonacci sequence. It shows up all over nature. But what's the full explanation behind it?
Two scientists recently wagered a bottle of whiskey. The bet? Whether we'll find evidence of advanced extraterrestrial life in the next 15 years.
Life became a possibility in the Universe as soon as the raw ingredients were present. But living, inhabited worlds required a bit more.
Today, supermassive black holes and their host galaxies tell a specific story in terms of mass. But JWST reveals a different story early on.
Observations of an enormous cosmic structure, dubbed the "Big Ring," seem to violate the Copernican principle.
Fire was crucial to the evolution of human technology. That's why alien species stuck in the "oxygen bottleneck" may be forever primitive.
One newly discovered, ancient star has a composition unlike any other. Explaining its existence is already blowing astronomers' minds.
Planets can be Earth-like or Neptune-like, but only rarely are in between. This hot, Saturn-like planet hints at a solution to this puzzle.
The midwest is particularly filled with them.
Finding it at all was a happy accident. Examining it further may help unlock the secrets hiding within the earliest galaxies of all.
A new measurement offers insights on the density of the mysterious force driving the Universe's expansion.
Each time you fold a piece of paper, you double the paper's thickness. It doesn't take all that long to even reach the Moon.
The record-breaking transmission could revolutionize deep space communication.
The cosmic scales governing the Universe are almost unbelievably large. What if we shrunk the Sun down to be just a grain of sand?
Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.
With the invention of the leap year, the Julian calendar was used worldwide for over 1500 years. Over time, it led only to catastrophe.
Earth wasn't created until more than 9 billion years after the Big Bang. In some lucky places, life could have arisen almost right away.
The first stars in the Universe were made of pristine material: hydrogen and helium alone. Once they die, nothing escapes their pollution.
The first tests of optical communications far from Earth will take place aboard the asteroid-bound Psyche spacecraft
The Universe is an amazing place. Under the incredible, infrared gaze of JWST, it's coming into focus better than ever before.
Physicists have yet to pinpoint the hypothetical matter that keeps galaxies from flying apart. Now they have a new focus.
As Uranus approaches its solstice, its polar caps, rings, and moons come into their best focus ever under JWST's watchful eye. See it now!
Thanks to observations of gravitational waves, scientists were able to settle a longstanding debate over the speed of gravity.
Misinformation was extremely popular in 2023, as bad science often made global headlines. Learn the truth behind these 10 dubious stories.
