Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a ...

Exploring claims on the internet deepens instruction by helping students understand how knowledge is created and when it can ...

Researchers have uncovered more than a thousand previously unknown tectonic ridges across the Moon’s dark plains, showing the Moon is still contracting and reshaping itself. These features are among ...

NASA’s first crewed moon mission in decades was delayed as its engineers grapple with an all-too-familiar rocket problem: hydrogen leaks. Fixing the issue is even trickier than it may seem.

A stunning Moon–Mercury conjunction will light up the western sky on 18 February. The slim crescent Moon will appear close to Mercury just after sunset. Here’s when to look, where it will be visible ...

New observations of the Moon have now found small mare ridges (SMRs), faults located in the lunar maria, the dark basalt plains of the Moon. These are what we normally call seas, such as the Sea of ...

On February 17, an annular solar eclipse, known as the “Ring of Fire,” occurred over Antarctica, creating a striking visual, ...

Smithsonian scientists have mapped thousands of young ridges across the lunar maria, which are large, basaltic plains on the ...

A look at the debate over building a city on the Moon or Mars, covering scientific findings, mission timelines and challenges discussed on the Fiction Science podcast.

Scientists have produced the first global map and analysis of small mare ridges (SMRs) on the moon, a characteristic geological feature of tectonic activity. Published in The Planetary Science Journal ...

Low, winding ridges run across the Moon’s dark plains like faint seams in cooled wax. They are easy to miss in a wide photo. Up close, they look like the surface has been gently pushed from below. A ...

The Moon, long treated as a geologically inert relic, is still contracting and cracking. A growing body of peer-reviewed research now confirms that tectonic faulting on the lunar surface has occurred ...
