life beyond earth
Back in 1990, we hadn't discovered a single planet outside of our Solar System. Here are 10 facts that would've surprised every astronomer.
composite JWST ALMA HST Fomalhaut
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST's eyes, astronomers found so much more.
four exoplanets super-earth mini-neptune
They're the most common type of exoplanet known today, and many astronomers have called them "super-habitable." None of that is true.
perseverance ingenuity mars
Mars, the red planet, was a world we knew almost nothing about until our first spacecraft visited it. In just ~50 years, how far we've come!
universe temperature
Before there were planets, stars, and galaxies, before even neutral atoms or stable protons, there was the Big Bang. How did we prove it?
black hole
Einstein's relativity overthrew the notion of absolute space and time, replacing them with a spacetime fabric. But is spacetime truly real?
sun red giant swallow planet
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!
jwst background galaxies
These high-mass, rapidly star-forming galaxies have called modern cosmology into question. But hi-res simulations show no tension at all.
dark energy accelerated expansion
All forms of energy affect the expanding Universe. But if matter and radiation slow the expansion down, how does dark energy speed it up?
JWST most distant galaxy proto-cluster
Finding out how the Universe grew up was the biggest science goal of JWST. This ultra-early proto-galaxy cluster is one amazing discovery.
jwst background galaxies
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.

JWST vs Hubble deep field
With infrared capabilities and image sharpness far beyond Hubble's limits, JWST looked at Hubble's deepest field, revealing so much more.
a very large cluster of stars in the sky.
Stars orbiting black holes were observed to move significantly slower than expected. One explanation centers on dark matter.
Uranus 1986 Voyager 2 2023 JWST
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.
two colliding white dwarfs trigger a type Ia supernova
When white dwarfs explode, they create a type Ia supernovae. After decades of following the leading theory, here's the complete overhaul!
map of earth eclipse path April 8 2024
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!
a very large spiral shaped object in the sky.
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?
Hubble view of galaxy containing GRB 221009A BOAT
Gamma-ray bursts are among the most energetic cosmic events of all. On October 9, 2022, a remarkable one occurred: the brightest ever seen.
JWST CEERS 1 hour field
Many galaxies really are ultra-distant, but some are just intrinsically red or dusty. Only with spectroscopy can JWST tell which is which.
mauritius reunion ISS earth night
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.
uap ufo UAPs UFOs
Lots of people have seen lots of bizarre events and phenomena that defy our conventional experience. But is there a scientific explanation?
the sun is setting over the ocean on a cloudy day.
Temperatures in the Sun's core exceed 10 million degrees Celsius. But how on Earth did we actually come to know that?
inside of xenon
With a bigger, better, and more sensitive detector, the XENON collaboration joins LZ and PANDA-X in constraining WIMP dark matter.
runaway supermassive black hole
Speeding through the Universe and leaving a wake of new stars, this runaway supermassive black hole is likely the first among thousands.
WR 124 JWST composite
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.
