Believing is Seeing

October 22, 2020 Theories provide context for observations. Recent data from the twin Voyager spacecraft reveals that the Interstellar Medium surrounding the Solar System is a diffuse region of charged particles, primarily ionized hydrogen, with a density of about one atom per cubic centimeter. However, between galaxies, astrophysicists estimate that…

Tilted Haloes

October 21, 2020 Galaxies are electrical in nature. According to a recent press release, the Milky Way galaxy is “…surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars.” Named the circumgalactic medium (CGM), it is where astronomers say…

Plasma Science

October 16, 2020 Astronomers find many celestial phenomena to be unexpected. Many of those phenomena are familiar, even though they are not easily explained. The aurorae at each of Earth’s poles are familiar to most people, although the way they form is not completely understood. Similarly, lightning bolts are familiar…

Langmuir Bursts

October 15, 2020 What powers coronal mass ejections? According to a recent press release, solar flares are driven by magnetized loops of plasma. The magnetic fields in the “magnetic flux ropes” experience “reconnection events” in which the field lines break and then reconnect, causing explosions of “magnetic energy.” Some of that…

Space Is Not a Thing

October 13, 2020 Stars are born where regions of space accumulate dense electric charge. Stars are concentrations of electricity that result from Birkeland currents and electric charge separation in space. Therefore, conventional models of stellar evolution reveal almost nothing about how stars are born and behave. Red giant stars, as…

Calm Before the Storm

October 12, 2020 Sunspots are mysterious. According to a recent press release, heliophysicists are studying sunspots fields in order to understand how similar phenomena might occur on other stars. Beginning with data from the Solar Dynamics Observatory and the Hinode mission, scientists “smeared” the datapoints into broad images. This gave…
