Astronomers use vanishing neutron star to measure space-time warp
In an interstellar race against time, astronomers have measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star—just before it vanished from view.

A tale of two pulsars' tails: Plumes offer geometry lessons to astronomers
Like cosmic lighthouses sweeping the universe with bursts of energy, pulsars have fascinated and baffled astronomers since they were first discovered 50 years ago. In two studies, international teams of astronomers suggest ...

A 70 degree shift on Jupiter's icy moon Europa was the last event to fracture its surface
Europa's outer icy shell has completely reoriented itself in one of the last geologic events recorded on its young surface. Europa's poles are not where they used to be. Cracks in the surface of Jupiter's icy moon indicate ...

'True polar wander' may have caused ice age
Earth's latest ice age may have been caused by changes deep inside the planet. Based on evidence from the Pacific Ocean, including the position of the Hawaiian Islands, Rice University geophysicists have determined Earth ...

NASA study solves two mysteries about wobbling Earth
Using satellite data on how water moves around Earth, NASA scientists have solved two mysteries about wobbles in the planet's rotation—one new and one more than a century old. The research may help improve our knowledge ...

New evidence suggests large asteroid strike may have influenced Mercury's spin
(PhysOrg.com) -- Planets orbiting a sun generally, but not always spin on their axis. Some spin east to west, others west to east. Those that don’t spin are said to be tidal locked with their sun; always showing it ...
Scientists ID three causes of Earth's spin axis drift
A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect—in both shape and in rotation.

Pluto's 'heart' may be cold as ice, but it's in the right place, according to research
Sputnik Planitia, a 1,000-kilometer wide basin within the iconic heart-shaped region observed on Pluto's surface, could be in its present location because accumulation of ice made the dwarf planet roll over, creating cracks ...

Image: Crater 'tree rings' on Mars
This feature could easily be mistaken for a tree stump with characteristic concentric rings. It's actually an impressive birds-eye view into an ice-rich impact crater on Mars. Tree rings provide snapshots of Earth's past ...
