Walkabout the Galaxy
Astrophysics and Astronomy | Physics
The astroquarks are face to face to face at a safe physical (not social!) distance. We zoom out, without zoom, to explore the question of the origin of life in an immense universe. People are fixin' to go back to space from the U.S., Pluto's atmosphere may stick around longer than though, and there's plenty of space news and human spaceflight trivia.
When you're out and about, do you enjoy the gentle touch of a summer breeze? On your walkabout the galaxy, let the solar wind add a breath of fresh plasma to your journey, with a vigorously stiff breeze of protons and electrons travelling at several hundred kilometers per second. But you won't need a windbreaker, thanks to our barely perceptible pressure of near-nano pascals, coupled with a toasty 100,000 degree temperature. The solar wind is happy to be your companion on your alkabout the Solar System. The Solar Wind, solar heating for kids. (Ready Brek)
