Asteroid 2023 JF flew about 199,000 miles (320,000 km) away from Earth. It's estimated size is about 34 feet wide (10 meters) ...

If you thought humanity already had its hands full with climate change, think again. With satellites and space junk increasingly cluttering our planet’s low Earth orbit, a team of scientists warn that ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...

This is a brilliant question because the notion of an orbit is counterintuitive. We know that massive objects (really, any objects with mass) gravitationally attract other massive objects; Newton’s ...

WASHINGTON — New analysis suggests that problems with NASA’s MAVEN Mars orbiter may be more serious than a simple communications glitch. NASA said Dec. 9 that it lost contact with the spacecraft three ...

A network of powerful ground-based telescopes captured rare starspot-crossing events on TOI-3884b, revealing cooler patches on the star’s surface and rapid changes tied to its rotation. By combining ...

Have you ever wondered how long it takes for each planet to orbit the Sun? From Mercury’s blazing 88-day year to Neptune’s astonishing 165-year journey, every planet moves at a completely different ...

When you see art of our solar system as the planet orbit the sun, you may notice that Earth's orbit has a tilt. It is not a perfect circle. What's more, Earth is not the only planet that displays such ...

The Moon is getting 1½ inches (3.8 centimeters) farther away from the Earth every year. Scientists measure the distance to the Moon by bouncing lasers off mirrors placed there by space probes and ...

James O'Donoghue receives funding from the UK Science and Technology Facilities Council (STFC). Earth will complete a rotation 1.33 milliseconds earlier than usual on Tuesday, August 5. That makes it ...

Just as Jupiter and Mars do every few years, music and science will align on July 13 for a multimedia performance of "The Planets" at Tilles Center in Brookville. The event, titled "Out of This World, ...
