It’s not a question of could they, but have they? Here’s how we’ll find out. It’s no secret that fragments of asteroids, comets, and other spaceborne objects have been found here […]
If everything eventually dies and decays, is there a way to prolong the inevitable? Our Universe, as it exists today, puts us in an incredibly privileged position. Had we come […]
The night sky is already noticeably different, and bigger changes are ahead. For all of human history until the launch of Sputnik, the only objects in the night sky were naturally […]
A case for looking beyond the planetary scientist’s (or even the astronomer’s) definition. Ever since 2006, when the International Astronomical Union (IAU) officially defined the term planet — introducing the term ‘dwarf […]
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 once thought the Moon was completely airless, but it turns out it has an atmosphere, after all. Even wilder: It has a tail of its own.
The largest moon in our Solar System, often overlooked, is a water-rich world. Does that mean life? Here on Earth, life took hold very early on in our planet’s history, and […]
The rings are raining down onto the planet, and disappearing surprisingly fast. 4.5 billion years ago, our Solar System first formed. Protoplanetary disks, which all solar systems are thought to […]
‘Fast Optical Bursts’ will confound ground-based astronomy. As of 2021, planet Earth is currently experiencing the least pristine night sky in recorded history. Prior to the development of artificial lighting, […]
It’s one of only five spacecraft that will exit the Solar System, and the only one we have a chance to aim at another star. Of all the spacecraft ever launched, […]
What will it take to conquer our immemorial space dream?
As the fabled star continues to dim, the world holds its breath and hopes. Here’s what’s in store when the fateful day arrives. The stars in the night sky, normally static […]
It’s the largest, most massive planet in the Solar System. But what’s the real story behind all the impacts on Jupiter? One of the most terrifying prospects here on Earth is […]
Over the coming decades, over 100,000 new satellites are expected. For countless millennia, whenever we were faced with a clear, cloudless, moonless night, all of humanity was able to witness […]
Want some crazy space phenomena? You don't have to leave the neighborhood for it.
An unprecedented number of new satellites threatens the night sky as we know it. Will we act in time to save it?
It’s one of the two best meteor showers of the year. Don’t let the full Moon stop you. Every year, as the Earth intercepts the debris streams of comets and asteroids […]
Black holes are regions of extreme gravity, but dark matter barely interacts at all. Do they play well together? Black holes are some of the most extreme objects in the […]
This is what we’ve learned from first object ever discovered to enter our Solar System from interstellar space. Billions of years ago, our Solar System was an extraordinarily different place […]
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 […]
Doomsday prophesies have never once come to pass, but they’ve never had science on their side like this before. Every year, the Earth completes an orbital revolution around the Sun, returning […]
Imagine you had perfect technology and unlimited fuel. How far could you go? Human spaceflight has brought us beyond Earth, but we could potentially venture even farther. The very first launch […]
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 […]
