Walkabout the Galaxy
Great American Eclipse, Sun, Antares
Astrophysics and Astronomy | Physics
The astroquarks tell their eclipse stories from the Great American Eclipse. The Sun and every star has weather, spots, oscillations, flares and all sorts of activity. Some of this is revealed during an eclipse to the naked eye. Now, telescopes have enabled us to map the appearance of the red supergiant, Antares. Join Josh, Addie and Jim for this stellar episode of Walkabout the Galaxy.
A joint Helios-Selene production, these sparkling jewels of light pierce the valleys and crater rims of your moon, at second and third contacts of a total solar eclipse, seen from your fine planet earth. Luna and Sol are delighted to provide this treat to residents of this third rock from the Sun, and we congratulate both Sir Edmund Halley for first describing how the Sun and the Moon combine to create the celestial gems of light, and Francis Baily, who described it again, more that 100 later, somehow managing to get them named after him, perhaps because Halley already had a comet. Baily's Beads is proud to bring you this episode of Walkabout the Galaxy following our most recent production on August 21, 2017. Get yourself a set of Baily's Beads next time next time they are available, and Helios and Selene will throw in not one, but two, free diamond rings. Baily's Beads and Diamond Rings are trademarks of Helios and Selene productions. Baily's Beads, available at every total solar eclipse, no warranties applied, subject to precise positioning and space time coordinates, and favorable viewing conditions.
