Recent flybys of the fiery world refute a leading theory of its inner structure—and reveal how little is understood about ...

#2. The Moon came from Earth. It didn’t form beside our planet, and Earth’s gravity didn’t capture it. The latest theory says ...

ESA's Mars Express orbiter captured footage of the Mars' moon Deimos pass in front of Ganymede, Europa, Jupiter, Io and ...

Stunning new Jupiter photos from NASA’s Juno spacecraft reveal storms, cloud bands, and its volcanic moon Io as the mission nears its final orbits around the gas giant.

Juno’s trajectory passes by Io every other orbit, flying over the same part of the moon each time. In December 2023, Juno came within about 930 miles of Io's surface – equal the distance from ...

A recent study found that Jupiter was once twice the size that it is now, making it big enough to swallow up 2,000 Earths.

NASA's Lunar Reconnaissance Orbiter (LRO) has imaged the crash site of Resilience, a moon lander built and operated by the ...

China’s Tiandu-1 satellite has entered a critical fuel-efficient orbit that synchronises with the motion of the Earth and moon, but claims that it is the first spacecraft to achieve the feat ...

Webb's final snapshot of asteroid 2024 YR4 fine-tuned its orbit—raising Moon impact odds slightly, but Earth is safe.

"That’s because we’re in the midst of a major lunar standstill," which has to do with the moon's orbit around the Earth. "It’s all about the inclination of the moon’s orbit, which ...

Adding, “We don’t always get them because the moon’s orbit is more of an oval. So, when the moon is at its closest orbit to Earth, called a perigee, we get a supermoon.” He says during ...
