From size to mass to density and more, each world in our Solar System is unique. When we compare them, the results are truly shocking.
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.
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we’re woefully unprepared.
65 million years ago, a massive asteroid struck Earth. Not only did Jupiter not stop it, but it probably caused the impact itself.
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.
In 2020, scientists took more than a kilo of moon rock and soil back to Earth for testing.
The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.
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.
Do you think you know the Solar System? Here’s a fact about each planet that might surprise you when you see it!
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.
The secret ingredient is violence, and it just might indicate that “moonmoons” aren’t as uncommon as most astronomers think.
Despite billions of years of life on Earth, humans first arose only ~300,000 years ago. It took all that time to make our arrival possible.
The James Webb Space Telescope (JWST) will study many dangerous cosmic phenomena, knowledge of which may help save humanity.
This technological feat changes our cosmic history.
Straddling the bounds of science and religion, Newton wondered who set the planets in motion. Astrophysics reveals the answer.
A Harvard astronomer went to the bottom of the ocean, claiming he recovered alien technology. But what does the science actually indicate?
Pluto failed to meet the definition of a planet, but some astronomers think there might be a legitimate Planet 9 out there.
Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it’s funded, and soon.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
A conversation with an advanced alien species is likely to be simple and to take 1,000 years. It might also be dangerous.
How did the troughs form?
The recently discovered Oort cloud comet, Bernardinelli–Bernstein, has the largest known nucleus: 119 km. Here’s what it could do to Earth.
From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?
