During this geomagnetic disturbance, known as the Laschamp event or the Laschamp excursion, the planet's magnetic north and south weakened, and the magnetic field tilted on its axis and diminished to a fraction of its former strength.
We have written many articles about the Earth’s tilt for Universe Today. Here’s an article aboutwhy Earth has seasons, and here’s an article about theEarth’s axis. If you’d like more info on Earth, check outNASA’s Solar System Exploration Guide on Earth. And here’s a link to...
By using data fromNASA’s Galileo spacecraft to analyze the distinctive cracks lining the surface ofEuropa, NASA scientists determined that Europa likely rotated around a tilted axis at some point. This tilt could influence calculations of how much of Europa’s history is recorded in its frozen ...
Uranus has two anomalous tilts, of its rotation axis and of its dipole axis. Unlike the other planets, the rotation axis of Uranus is tilted 97.5° ... CT Russell,MK Dougherty - 《Space Science Reviews》 被引量: 183发表: 2010年
Here we present laboratory analogue experiments and propose that Saturn鈥檚 cyclonic circulation can be explained by tilted convection in which buoyancy forces do not align with the planet鈥檚 rotation axis. In our experiments鈥攃onducted with a cylindrical water tank that is heated at the bottom,...
This is mainly due to difficulties in its imaging and uncertainty in its rheology. Investigation of seismic anisotropy from propagation of teleseismic P and S waves in three dimensions (3D), i.e., with no limitation imposed on the symmetry axis orientation into the horizontal or vertical ...
Based on our previous work (Vidotto et al. 2009a), we investigate the effects on the wind and magnetospheric structures of weak-lined T Tauri stars due to a misalignment between the axis of rotation of the star and its magnetic dipole moment vector. In such configuration, the system loses ...
During this geomagnetic disturbance, known as the Laschamp event or the Laschamp excursion, the planet's magnetic north and south weakened, and the magnetic field tilted on its axis and diminished to a fraction of its former strength. This lessened the magnetic pull that normally directs...
The kinematic properties, represented by travel time, are described by Equation (5), which is a hyperbolic equation focused on the time axis. The time–distance curve exhibits the same asymptote of 𝑡=±2/𝑣t=±2/v for targets at different depths. But it is not the same for vertices...
