A NASA image of plasma bursting from the sun. Plasma—a hot soup of atoms with free-moving electrons and ions—is the most abundant form of matter in the universe, found throughout our solar system in the sun and other planetary bodies. A new study from University of Rochester researchers ...
When discussing the magnetosphere, the plasma in question is the hot material of the sun that escapes the gravitational field of the sun as a result of its extreme energy. As it travels through space, the plasma particles are called solar wind....

abbreviated as ly, measures the distance thatlightcan travel in a year. In one millisecond,lightcan cover a distance of 300,000 meters. This is about five hundred and eighty miles. Therefore,light can go as fastas sound and a millisecond can cover one million kilometers. ...
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
The solar wind is simply stated as the medium comprising tenuous magnetized plasma consisting of ions and electrons that flow from the sun. Its velocity ranges from 400 km/s (slow speed) to 750 km/s (fast speed), and its variability can affect the Earth’s magnetosphere (Schwenn 2006). ...

Once an innate immune cell, such as a macrophage or other antigen-presenting cell (APC) engulfs an invading bacteria, virus, or vaccine, they often travel to a lymph node and present an antigen from that pathogen on the cell surface toT cells. They present the new antigen using specific ...
To know where it is and how fast it is moving, the orbiter uses global positioning systems (GPS). To know which way it is pointing (attitude), the orbiter has several gyroscopes. All of this information is fed into the flight computers for rendezvous and docking maneuvers, which are ...
The opposite does not occur. It is unusual for the antibodies in the plasma of the donated blood to react to the antigens on the recipients RBCs because very little plasma is transfused and it gets diluted to a level too low to cause a reaction. When a transfusion reaction occurs, an ...
