Einstein's relativity overthrew the notion of absolute space and time, replacing them with a spacetime fabric. But is spacetime truly real?
Many planets will eventually be devoured by their parent star. For the first time, we caught a star in the act, eating its innermost planet!
These high-mass, rapidly star-forming galaxies have called modern cosmology into question. But hi-res simulations show no tension at all.
All forms of energy affect the expanding Universe. But if matter and radiation slow the expansion down, how does dark energy speed it up?
Finding out how the Universe grew up was the biggest science goal of JWST. This ultra-early proto-galaxy cluster is one amazing discovery.
From quarks and gluons to giant galaxy clusters, everything that exists in our Universe is determined by what is (and isn't) bound together.
The acceptance of our cosmic loneliness and the rarity of our planet is a wakeup call.

With infrared capabilities and image sharpness far beyond Hubble's limits, JWST looked at Hubble's deepest field, revealing so much more.
Stars orbiting black holes were observed to move significantly slower than expected. One explanation centers on dark matter.
Voyager 2 flew past Uranus in 1986, finding a bland, featureless world. Now, in 2023, JWST's sights are similar. There's a reason for that.
Eternal twilight.
When white dwarfs explode, they create a type Ia supernovae. After decades of following the leading theory, here's the complete overhaul!
The next solar eclipse to occur over heavily populated areas is on April 8, 2024. For a spectacular show; here's where the best views are!
Finding this missing piece of water’s path through the universe offers clues to how it came to be on Earth.
If the evolution of the Universe is a movie, what happens when we rewind it all the way backward?
Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.
Many galaxies really are ultra-distant, but some are just intrinsically red or dusty. Only with spectroscopy can JWST tell which is which.
Mercury, Venus, and Mars are all uni-plate planets, and may always have been. Here's what's known about why Earth, uniquely, has plate tectonics.
We are about to learn a lot more about the most elusive of cosmic particles.
Lots of people have seen lots of bizarre events and phenomena that defy our conventional experience. But is there a scientific explanation?
Temperatures in the Sun's core exceed 10 million degrees Celsius. But how on Earth did we actually come to know that?
With a bigger, better, and more sensitive detector, the XENON collaboration joins LZ and PANDA-X in constraining WIMP dark matter.
Speeding through the Universe and leaving a wake of new stars, this runaway supermassive black hole is likely the first among thousands.
This beautiful JWST image of Wolf-Rayet star WR 124 has been called a "prelude to a supernova" by NASA. That might be entirely wrong.
How scientists found out that we live in a cosmic aquarium.
Many impact craters on Earth have been erased thanks to wind, water, and plate tectonics. But scientists have clever ways to find them.
It's the best-known transcendental number of all-time, and March 14 (3/14 in many countries) is the perfect time to celebrate Pi (π) Day!
Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where's the line between them?
The 1,200-year-old "Book of Ingenious Devices" contains designs for futuristic inventions like gas masks, water fountains, and digging machines.
What kind of object will you form? What will its fate be? How long will a star live? Almost everything is determined by mass alone.
