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 […]
It doesn’t propagate at infinite speeds, and that’s a problem for Newton. When you look at the Sun, the light you’re seeing isn’t the light that’s being emitted right now. Instead, […]
It’s a supergiant star in the final stage of its life, and it just dimmed by an enormous amount. What’s going on? When you take a look at the stars in […]
A new computer model solves a pair of Jovian riddles.
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 […]
The object, originally dubbed “Ultima Thule,” was renamed to “Arrokoth” due to the connection between the word “Thule” and the Nazis.
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 […]
And Dr. Jill Tarter never once lost her composure.
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 […]
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 […]
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 […]
If you’ve ever wondered what truly lies beyond Neptune, this is one interview you won’t want to miss! Our Solar System formed some 4.6 billion years ago from a molecular cloud […]
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 likely isn’t the rare occurrence we once thought it was. In our Solar System, there’s one overwhelming source of mass that all the planets orbit around: our Sun. Each planet […]
Time to build a Corellian shipyard?
There are millions of asteroids in the solar system. A new study might tell us where they came from.
It’s unlikely that there’s anything on the planet that is worth the cost of shipping it back
Any hypothesis, no matter how alluring, must be confronted with the full suite of data. Our Solar System may be the closest part of the Universe to us as we look […]
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.
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 […]
Not only can’t astronomers and planetary scientists agree, but the IAU made it worse for everyone. If you were alive in 2006, you likely remember a momentous event in astronomy: […]
Break out your prospecting gear and space suit.
When it comes time for humanity to pick a new home, where will we go?
You get out what you put in, and we haven’t truly invested in space since Apollo ended. Humanity should be an interplanetary civilization by now. There is no scientific reason that […]
The ‘giant impact’ that led to Earth might not have been so giant, after all. A little over 4.5 billion years ago, our Solar System began to form. Somewhere in the […]
How ‘special’ are we for life to have survived and thrived the way it did? While there are hundreds of billions of stars in our galaxy, many with Earth-sized planets at […]
From 4 billion miles away, it says a lot about the meaning of time.
SpaceX CEO Elon Musk is encouraging aerospace companies to up their game after successfully launching the most powerful rocket since NASA’s Saturn V.
