Solar Flares and the Solar Sycle
The Celestial Sphere By Matthew Johnson In the final hours of Dec. 31, 2023, the sun produced a X5.0 solar flare (R3 Strong Radio Blackout), the largest flare observed by the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center since 2017. There was also a Coronal Mass Ejection (CME) related to this event. This […]
Winter Solstice Occurs Dec. 21
The Celestial Sphere By Mathew Johnson The word “solstice” comes from the Latin sol (sun) and sistere (to not move).

All solar eclipses occur when the moon in its orbit comes to cover the disc of the sun. What makes this eclipse special is that a good view is within […]
Politics in Space and an August Supermoon
By Matthew Johnson Russia’s war in the Ukraine has extended beyond Ukraine’s borders. It has entered our celestial sphere. In early July, NASA issued a statement condemning images displayed by the cosmonauts from the International Space Station (ISS) by Russia’s space agency “Roscosmos.” Images were displayed in space, circling the Earth every 90 minutes. The […]
An Unusual Lineup of the Planets This June
The Celestial Sphere By Matthew Johnson The beginning of summer occurs on June 21 at 5:14 a.m. on the day celebrated as the summer solstice. The summer solstice occurs when the Northern Hemisphere of the earth becomes tilted toward the sun to its greatest extent, the North Pole glowing with 24 hours of daylight. On […]
Craters and Rays Mark the Battered Surface of the Moon
The Celestial Sphere By Matthew Johnson Looking up at the moon, one will notice that it has a battered surface, created both by lava flows and quakes and by colliding asteroids and comets. Impacts from asteroids and comets shattered the young moon’s crust, forming deep circular craters surrounded by high-rising crater rims with long ejected […]
March Viewing
The Celestial Sphere by Matthew Johnson With temperatures hovering between zero and 15 degrees for most of our Norfolk winter days and nights, the warmer weather that springtime brings will be a welcome event. The transition from winter to spring begins on March 20 at 11:33 a.m. with the long-awaited vernal equinox. On the equinox […]
The Sky’s No Limit in 2022
The Celestial Sphere by Matthew Johnson With space missions planned for launch by Russia, Japan, South Korea, the European Space Agency (ESA) and NASA, and the James Webb Space Telescope functioning properly after achieving its distant orbit away from the thermal interference of the earth, moon and sun, 2022 may prove to be a spectacular […]
