Context. As a star evolves, the planet orbits change with time due to tidal interactions, stellar mass losses, friction and gravitational drag forces, mass accretion and evaporation on/by the planet.

It’s not so much a traditional clock as it is a measuring tool, but it’s all that’s needed to do some basic, interplanetary calculations As an example, the team suggests a scenario in which a ...

The cloudier an alien planet is, the closer it can get to its star and still remain potentially life-friendly, researchers say. In fact, clouds might help Earth-like planets remain hospitable to life ...

Astronomers using NASA’s Hubble Space Telescope have measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the ...

There are incalculable oddities in our solar system, and myriad ways that planets are different from Earth. One surprising factor you might not have considered is how planets rotate. While we all ...

A day on Earth lasts a familiar 24 hours, but across the solar system, time moves very differently. Some planets rotate slowly that a single day can last longer than an entire year, while others spin ...

New research gives the first accurate estimate of how much faster the Earth’s core is rotating compared to the rest of the planet. Previous research had shown that the Earth’s core rotates faster than ...

This is one of the best weeks of the year to go stargazing. No, really! The Moon is waning to a crescent and nowhere to be seen unless you’re out really late into the early hours. The arc of the Milky ...
