For now, our Solar System’s eight planets are all safe, and relatively stable. Billions of years from now, everything will be different.
The 5th brightest star in our night sky is young, blue, and apparently devoid of massive planets. New JWST observations deepen the mystery.
A surprising JWST discovery around Fomalhaut has a different, superior explanation: not a great dust cloud, but a mere background object.
The nearby, bright star Fomalhaut had the first optically imaged planetary candidate. Using JWST’s eyes, astronomers found so much more.
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.
Meanwhile meteorite hunters rushed to Berlin to find this most rare space rock.
In July of 2022, the first science images from JWST were unveiled. Two years later, it’s changed our view of the Universe.
65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it probably caused the impact itself.
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we’re woefully unprepared.
The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.
National Geographic’s first James Webb Space Telescope book shows us the cosmos like never before.
In 2020, scientists took more than a kilo of moon rock and soil back to Earth for testing.

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.
The Earth that exists today wasn’t formed simultaneously with the Sun and the other planets. In some ways, we’re quite a latecomer.
Can two planets stably share the same orbit? Conventional wisdom says no, but a look at Saturn’s moons might tell a different story.

NASA’s space telescopes and observatories bring humanity unrivaled science images and scientific discoveries. Here’s what should be next.
Straddling the bounds of science and religion, Newton wondered who set the planets in motion. Astrophysics reveals the answer.
The closest known star that will soon undergo a core-collapse supernova is Betelgeuse, just 640 light-years away. Here’s what we’ll observe.
This technological feat changes our cosmic history.
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
A Harvard astronomer went to the bottom of the ocean, claiming he recovered alien technology. But what does the science actually indicate?
There was a lot of hype and a lot of nonsense, but also some profoundly major advances. Here are the biggest ones you may have missed.
