star formation; Milky Way
Astrophysics and Astronomy | Physics
The Astroquarks assemble to examine the mysterious of a star that is blocked out perhaps by a giant dust cloud. Meanwhile, the Sun is passing through a Local Bubble in the Milky Way that has triggered star formation all around us. Join us for all this, rainbow trivia, and more.
To liven up your day, try rainbows. These colorful manifestations of a combination of refraction and reflection inside water droplets in the atmosphere can bring a sense of calm and joy to your hectic daily routine. Reliably at an angular distance of 42 degrees from your line of sight away from the sun, and spanning all the colors visible to the human eye, and more, rainbows are available in single and double versions depending on the number of reflections inside the droplet. And for the adventurous, go airborne to get a full circle rainbow. While you won't find a pot of gold at the end of one, or, in fact, even find the end of a rainbow at all given that it is a virtual image, we guarantee you will find a sense of peace and harmony with the realization that nature is cool. Or your money back. Rainbows, show your colors (Smarties).
