Earth surrounded by plasma from a distant pulsar. Image was prepared using DALEE and is not a scientific image.

Plasma storms have been found in space around Earth that is supposed to be empty.

By analyzing a twinkling pulsar, scientists have mapped plasma plumes and a bow shock wave with unprecedented clarity, upending the assumption that our local interstellar neighborhood is calm.

Are events in the distant past, such as the extinction of the dinosaurs, about ten percent closer in time to us? And how does it relate to solar flares? This is according to an ongoing study by a group led by Prof. Yitzhak Orion from Ben University

Niv asks: Why does the compass point north if the dynamo that flows under the surface of the ground, under the entire earth, is the one that creates the magnetism?

The magnetic field and electric currents in and around the Earth produce complex forces that have a huge impact on our day-to-day lives. One can imagine the field as a giant bubble, protecting us from space radiation and charged particles with which solar winds bombard the earth. Credit: ESA/ATG medialab

These micrometeorites are composed of iron oxides formed when meteoric iron dust particles oxidized as they traversed Earth's atmosphere, revealing that the upper atmosphere was surprisingly rich in oxygen.Credit: Andrew Tomkins
