Are there any moons that are made of gas?

The planets in our solar system come in two forms: Some are rocky, and some are gaseous. But all of the moons in our solar system are rocky, even the ones that orbit gas giants. So why aren’t some moons in the solar system made of gas? And are there gaseous moons anywhere in the … Read more

China’s Yutu 2 rover beams back stunning image after 3 years on moon’s far side

Time-lapse imaging of Yutu 2 progress across the lunar landscape. (Image credit: NASA/GSFC/Arizona State University) China’s Yutu 2 rover has returned a view of its path over three years of travels across the harsh environment of the moon’s far side.

Behold, This Is The First Asteroid Ever Discovered to Have Three Moons

An asteroid discovered in the 19th century has just been identified as the most crowded we’ve ever found. It’s called 130 Elektra, or just Elektra for short, and astronomers have just discovered that it has not one, nor two, but three smaller satellite companions, or moons. That not only makes it the most numerous asteroid … Read more

Moon’s Hidden Depths Uncovered with New Algorithm

Certain areas near the moon’s poles linger perpetually in shadow, never receiving direct sunlight. Recent studies suggest these so-called permanently shadowed regions (PSRs) contain rich ice reservoirs that could reveal details about the early solar system; they could also help future visitors make fuel and other resources. But these areas are hard to photograph from … Read more

White dwarf star circled by 65 objects may host a planet in its habitable zone

Astronomers have found 65 evenly spaced rocks orbiting a white dwarf star in its habitable zone, hinting that a planet’s gravity may be holding them there Space 11 February 2022 By Leah Crane Illustration of the white dwarf star WD 1054-226 orbited by clouds of planetary debris and a major planet in the habitable zone … Read more

NASA prepares for moon’s dark south pole in eerie lights-out ‘spacewalk’ (photo)

NASA is preparing for the day its astronauts explore the south pole of the moon by heading underwater with the lights out. NASA has long used a vast swimming pool dubbed the Neutral Buoyancy Laboratory to prepare for spacewalks, since the underwater work experience is the closest they can get to reduced-gravity environments before blasting … Read more

Life-enabling moons can probably only form around small planets, study finds

Earth’s moon is large for the planet’s size, and many astronomers have long believed that this fact has helped make Earth a habitable world. And a new study has now found that our planet was just the right size to form such a large, life-enabling moon.  The study, by researchers from the University of Rochester … Read more

Moons: Rocky planets much larger than Earth might not have natural satellites

Astronomers have found lots of exoplanets but not much evidence of exomoons, and a new model might explain why Space 1 February 2022 By Alex Wilkins An artist’s impression of an exoplanet Shutterstock / Artsiom P Rocky planets much bigger than Earth might not be able to form large moons like our own, which is … Read more
