Latest about gravity
Scientists still don't fully understand why some planets have hundreds of moons while others have none
It's not a competition, but if it were, Saturn would be winning.
Why does Earth look flat if it's really round?
It's all about perspective: The higher you go, the more you can see the curve.
How long does it take to travel to the moon?
The answer depends on many factors, including the amount of fuel needed, the moon's orbit and the mission's objectives.
Indian Ocean gravity hole: The dent in Earth's gravitational field created by the death of an ancient ocean
The Indian Ocean "gravity hole" is a region where Earth's mass is reduced, leading to weak gravitational pull, lower-than-average sea levels and a puzzle scientists have only just begun to solve.
James Webb telescope uncovers 1st-ever 'Einstein zig-zag' hiding in plain sight — and it could help save cosmology
A new JWST study has revealed the true origins of a luminous quasar that has been duplicated six times as its light "zig-zags" through space-time via a phenomenon first predicted by Albert Einstein. The unusual light show could help tackle one of cosmology's biggest problems, experts claim.
'Gravity waves' from Hurricane Helene seen rippling through the sky in new NASA images
Hurricane Helene sent gravity waves rippling through the atmosphere far above the southeastern United States, new NASA images reveal.
'God of chaos' asteroid may be transformed by tremors and landslides during 2029 flyby of Earth, study finds
When the 'God of chaos' asteroid Apophis makes an ultraclose flyby of Earth in 2029, our planet's gravity may trigger tremors and landslides that totally change the asteroid's surface.
Accidental discovery of 1st-ever 'black hole triple' system challenges what we know about how singularities form
Researchers spotted a second distant star orbiting a well-known black hole and its stellar companion in a never-before-seen gravitational triad. The system's unique configuration suggests that the black hole was not created as scientists initially expected.
The Milky Way could be part of a much larger 'cosmic neighborhood' than we realized, challenging our understanding of the universe
A probabilistic new map of the universe surrounding the Milky Way reveals that our galaxy is likely part of an even larger "basin of attraction" than we previously assumed.
