MIT scientists identify a plasma plume that naturally protects the earth against solar storms.
The Earth’s magnetic field, or magnetosphere, stretches from the planet’s core out into space, where it meets the solar wind, a stream of charged particles emitted by the Sun. For the most part, the magnetosphere acts as a shield to protect the Earth from this high-energy solar activity.
But when this field comes into contact with the Sun’s magnetic field — a process called “magnetic reconnection” — powerful electrical currents from the Sun can stream into Earth’s atmosphere, whipping up geomagnetic storms and space weather phenomena that can affect high-altitude aircraft, as well as astronauts on the International Space Station.
Now scientists at MIT and NASA have identified a process in the Earth’s magnetosphere that reinforces its shielding effect, keeping incoming solar energy at bay.
Researchers appear to be on the brink of an explanation for lightning strikes that sometimes precede earthquakes. Unlike normal lightning, which results from the buildup of charged regions in clouds, recent experiments in labs suggest that the so-called “earthquake lights” instead may originate from the shifting of granular materials in the ground around a geological fault. The research will be presented March 6 at the 2014 APS March Meeting in Denver, CO.
Astronomers have found Kepler-410Ab that is a Neptune-sized planet outside of our solar system in a binary star system. Read more…
Moon is the only natural satellite of Earth. People want to read about different facts about the moon and you probably have also come after searching.
We want to read about the facts but space agencies are working on the facts. Major space agencies of the world including NASA, ESO and the China National Space Administration are considering sending first manned missions to the satellite by the year 2020. India and Japan are also showing interests to send missions by that time. Read more…
Scientists have reported that “super-Earths” in our galaxy have more chances of having climate similar to Earth. These chances are more than our previous expectations. Read more…
