As evidenced decades ago, Earth is surrounded by a couple of radiation belts, atmospheric structures that contain large amounts of dangerous charged electrons. Some experts suggested that increased solar activity might be capable of driving them towards the surface, but new data shows that to be false.

In a series of previous studies, researchers proposed the existence of an atmosphere layer containing cold, electrically-charged particles, way above the planetary surface. The latest investigation into this issue reveals that to be true, as scientists discover cold plasma layer at the top of the atmosphere.

A team of geologists analyzing a puzzling rock sample discovered that it was made up of a type of crystal that had never before been encountered in nature. Scientists know all there is to know about this material, but only because they created it in the lab. Now, they hypothesize that the rock is in fact a meteorite.... |

Earlier today, I wrote a piece about the exoplanets Kepler-20e and Kepler-20f, which were found by the NASA Kepler Telescope about 1,000 light-years away. These objects, which you can now see in more detail, are the smallest exoplanets ever discovered.
In fact, one of them is smaller than Earth. Kepler-20e has a ra... |
