The European Space Agency’s Solar Orbiter recently captured images that could help scientists better under the mysterious physics of our Sun.
Due to a crust of carbon, the absence of oxygen, and constant bombardment from meteorites, the planet Mercury may be littered with diamonds.
Forty Starlink satellites were destroyed earlier this year in a geomagnetic storm.
Our research on a Martian meteorite provides new clues about early surface conditions on the red planet.
Once science operations begin for James Webb, we'll never look at the Universe the same way again. Here's what everyone should know.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
Besides offering an incredibly cool way to get stuff into space, SpinLaunch promises to reduce the cost of a launch by 20-fold.
Some stars burn through their fuel as expected, and die of natural causes. But others, instead, get murdered. Here's their story.
For many, it was just a successful launch like any other. But for scientists around the globe, it was a victory few dared to imagine.
Water on Mars is key for human survival on the Red Planet, not just for drinking but for growing food and making fuel and oxygen.
Whether NASA likes it or not, humans eventually will be having space sex.
In 2022, the probe will crash into an asteroid while a nearby satellite captures it on camera.
The stars, planets, and many moons are extremely round. Why don't they take other shapes?
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
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.
Based on the atoms that they're made out of, the innermost planet should always be the densest. Here's why Earth beats Mercury, hands down.
We’ve already observed three cases where it’s happened. When you look at an object in space, it’s pretty easy to tell if it’s a star or a planet. Stars are […]
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 […]
With sodium-sensitive eyes, we’d see it every new Moon. With no detectable gases, the Moon appears to be atmosphere-free. The Moon as seen from a view above the majority of Earth’s […]
When you measure not just light, but light’s polarization, you learn so much more. It’s been over 100 years since the first solution for a black hole was discovered in General […]
A tiny layer of microscopic dust is the only reason it appears red. When we look out at our planet Earth from space, we see a myriad of diverse colors. The […]
Our views from the red planet’s surface are more spectacular than ever. Ever since the earliest spaceflight, humanity has reached for Mars. This photo composite shows Meande Ring, a river on […]
Debris from Pluto-sized collisions, not aliens, are streaming through the galaxy. In 2017, scientists discovered an object passing through our Solar System that was unlike anything else we had ever seen. […]
Learn how to get the best views no matter where you are. Every year, no matter what else is occurring on Earth or in the heavens, you can rely on two […]
At its biggest for the next 15 years, it’s still much smaller than the Moon. On October 6, 2020, Mars makes its closest approach to Earth until 2035. Earth orbits in […]
The view is different for each of us, but this perspective unites us all. From anywhere on Earth, the entire sky rotates a full 360° every 24 hours. From Earth, star […]
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 […]
For the first time in many years, there’s currently a comet visible to the naked eye in Earth’s night sky: comet NEOWISE. For the first time in many years, there’s currently […]
The full Moon is always a sight worth looking at. This March, the full Worm Moon is a little more “super” than usual. The full Moon is always a spectacular sight: […]
And how cutting just $1 billion per year in funding from NASA’s budget would be a catastrophe for science. When you think of the great cosmic beyond and what we know […]
