Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively ...

I thought America was out of ideas. I thought our best days were behind us. And then I saw the video of the newly built Sphere in Las Vegas set against Independence Day fireworks as “Viva Las Vegas” ...

In a post yesterday, I talked about the Moon orbiting the Earth, and the Earth’s gravitational sphere of influence, called its Hill sphere. If you have an object orbiting the Sun (like a planet, say), ...

The Sphere would not gravitationally bind to its star in a stable fashion. This is perhaps counterintuitive; you might think that a perfect sphere around a star would be stable. But if any part of the ...

When you see a globe or other representation of Earth, it usually is shown as a perfect sphere, so many people may think that it is. The Earth, though, is what we call an Oblate Spheroid. It is a ...

Solar flares and other types of space weather can wreak havoc with spaceflight and with telecommunications and other types of satellites orbiting the Earth. But, to date, scientists’ ability to ...
