Biggest Betrayal Is When It’s Supposed To Thunderstorm And It Doesn’t

Astronaut Eugene A. Cernan's view from and of the Gemini-9A spacecraft during his extravehicular activity (EVA). Taken during the 32nd revolution of the 72-hour, 21-minute spaceflight.

"'What a beautiful spacecraft,' said Gemini IX pilot Eugene Cernan during his two hour, eight minute spacewalk. He took this wide-angle photograph looking back at the window where command pilot Tom Stafford was watching."

"Northwestern Mexico as seen from the Gemini-9A spacecraft during its 32nd revolution of Earth. The large penisula is Baja California. The body of water at lower right is the Pacific Ocean. The land mass at upper left is the State of Sonora. The Gulf of California separates Sonora from the peninsula."

Christmas Hanukkah in Space: Day 12

Jeff Hoffman of STS-61 demonstrates how a dreidel works in zero gravity and displays his traveling menorah on the first day of Hanukkah, December 1993. Hoffman was the second Jewish American astronaut and the first to spend the holiday in space.

A solar cycle: a montage of 10 years worth of x-ray images taken by the ようこう (Yōkō 'sunbeam') sun-observation satellite.

The Sun undergoes a cycle of magnetic activity with a period of about 11 years. At solar maximum, solar observatories see more sunspots on the Sun's surface. Solar flares and coronal mass ejections are bigger and more frequent, triggering auroræ in Earth's skies, interfering with some types of radio communication, and irradiating deep space hardware. The Sun's magnetic field also undergoes a polarity inversion during solar maximum, when the north and south magnetic poles on the Sun swap (this happens again 11 years later in the next maximum). By contrast, the solar minimum has very few or no sunspots and the Sun is generally calm; a good time for deep space missions.

The last solar maximum was in February 2014. The last minimum was December 2019, marking the transition from cycle 24 to 25 (records began in 1755). The next maximum is predicted for the second half of 2025.
