Forgetting them, at any step, can lead to unscientific conclusions. No one, not even the smartest among us, were competent scientists from the outset. The concept of science is simple […]

There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
The object, originally dubbed “Ultima Thule,” was renamed to “Arrokoth” due to the connection between the word “Thule” and the Nazis.
Happy birthday to Pluto, discovered on this day in 1930. Pluto, first discovered in 1930, was no more than a distant dot in our most powerful telescopes. Clyde Tombaugh’s original images […]
Don’t miss the summer’s greatest natural sights of all. Some of the natural highlights of our night sky are easy to overlook. Every year, you’ll hear about some of the brightest, […]
The Megachile pluto is about four times the size of a honeybee.
We’re not made out of the densest elements, but we’re the densest planet nonetheless. Here’s why. Of all the planets, dwarf planets, moons, asteroids and more in the Solar System, only […]
What if all planets were the same distance from Earth as the Moon?
There are three possible ways we’ll find alien life. With all of these chances, the only question is which will come first. Given everything humanity has learned about the Universe, it […]
Only 8 worlds make the astronomical cut as planets. Here are the 10 fascinating bodies that didn’t make it. Astronomically, bodies within the Solar System must achieve three criteria in order […]
The flying rotorcraft drone is set to land on Saturn’s largest moon in 2034.
Sometimes, the biggest answers to the deepest questions come in the most unexpected of places. In the Solar System, anything out past Neptune is generally considered to be the outer reaches […]
It may have been captured by Neptune since it formed, but Triton remains king of the Kuiper belt. Our Solar System is arguably the most well-studied corner of the Universe, with […]
Documentary explores astrobiology, astronauts, and the awe of it all.

The closest star to our own doesn’t just host one rocky planet, but a second, larger ‘super-Earth’ much farther out. Of all the stars in the Universe, the closest one to […]
Is there life beyond Earth, even in our Solar System? This mission might be humanity’s best hope of finding it. The biggest question facing humanity might be, “Does life exists beyond […]
Some have suggested that there is no hidden giant out there.
All the planets, asteroids, and Kuiper belt objects out there all point to the same conclusion: it’s giant impacts or no moons at all. Out of all the rocky planets […]
If you’re wondering whether the blast wave or the radiation would kill us first, you’re asking the wrong question. As far as raw explosive power goes, no other cataclysm in […]
Finding the Higgs boson, gravitational waves, and imaging a black hole’s event horizon were huge. There’s even more to the story. From a scientific point of view, the 2010s have been […]
Carl Sagan—who first coined the term—was tempted to call them “star-tar.”
If we restrict ourselves to looking for extraterrestrial life on Earth-like worlds, we might miss it entirely. When we think about life out there in the Universe, far beyond the […]
Forget about alien nonsense. The Universe as it actually is doesn’t need any embellishments to be interesting. In our Solar System, the planets, moons, asteroids, comets and other masses are […]
We’d never flown past or imaged a small, isolated Kuiper belt object before. Here’s what we know so far. As 2018 ended and 2019 began, NASA’s New Horizons flew past its […]
And one of our planets has the orbiting moons to prove it. Despite the dangers posed to planet Earth by a comet or asteroid strike, our Solar System is actually an […]
Cryovolcanoes that eject ice instead of magma have been confirmed to exist on Ceres, which will help studying this formation on other planets and moons throughout the solar system.
Is The Goblin’s orbit a breadcrumb leading us to Planet X?
In 1789, William Herschel discovered this unique moon around Saturn. 230 years later, its secrets are more promising than ever. Today marks the 230th anniversary of the discovery of Enceladus, one […]
If your goal was to destroy the science of astronomy and astrophysics, this is exactly how you’d do it. One of the perks of being President of the United States of […]
