Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

Astronomers have made the first direct observation of a spinning black hole twisting the very fabric of spacetime, a ...

When a star gets too close to a black hole, the gravity of the black hole changes what happens next in really big ways. They give us a chance to see h.

The extra precession of Mercury—42.9 seconds of arc per century—explained by General Relativity (GR), is the result of a secular addition of 5.02 × 10 −7 rad. at the end of every orbit around the Sun.

Earth wobbles on its axis like a spinning top, a motion called precession. This wobble takes about 26,000 years to complete one full circle. Different stars have served as the North Star throughout ...

Abstract: Nutation and precession parameter estimation is of great importance for attitude estimation of spin-stabilized space targets. In this paper, we propose a novel method to estimate the ...

Researchers conducted innovative simulations of spinning black holes grounded in general relativity, which clarified that the ultraluminous accretion disk (i.e., gaseous spiral surrounding a black ...

Researchers have measured the Milky Way’s warp precession with Cepheid stars, uncovering an oblate dark matter halo influencing the galaxy’s structural dynamics. Credit: Kaiyuan Hou and Zhanxun Dong ...

The warp in the Milky Way's spiral disk is precessing backward under the influence of the enormous mass of dark matter that forms an invisible halo around our galaxy, Chinese astronomers have ...

Here I discuss possible relations between free precession of neutron stars, Tkachenko waves inside them and glitches. I note that the proposed precession period of the isolated neutron star RX J0720.4 ...

This article was originally featured on The Conversation. Spring, summer, fall and winter–the seasons on Earth change every few months, around the same time every year. It’s easy to take this cycle ...

Nearby planets can affect how one planet 'wobbles' on its spin axis, which contributes to seasons. Mark Garlick/Science Photo Library via Getty Images Spring, summer, fall and winter – the seasons on ...
