036 - Spiral density waves The Skyentists

- Наука
After a long hiatus consequence of the very unusual times we all are living, The Skyentists, astronomers Kirsten Banks and Ángel López-Sánchez, are back to action. In addition to provide some quick comments about how their work and science communication activities have been affected during the last couple of months they also talk about recent astronomy news: the bright comet C/2020 F8 (Swan), the non-pink, non-super moon, and the apparent disintegration of exoplanet Fomalhaut b "Dagon". For "Space News" Ángel talks, surprise, surprise, about Betelgeuse, that has fully recovered its normal brightness, as a new research confirms that the reason of its unusual dimming was a dust cloud, while Kirsten celebrates the 30 anniversary of our beloved Hubble Space Telescope, for which she has been preparing some amazing short ( 1 min) videos in TikTok. Here and there plenty of feedback is answered (thank you!), including answering some clever astro-questions. The main topic of this episode is galaxies: they provide some "galaxy fun facts" and then discuss the "spiral density wave" theory that explains how the arms of spiral galaxies are created. For "What's Up!" they invite us to have a look to the beautiful edge-on spiral galaxy NGC 4565, the Needle galaxy, located in the constellation of Coma Berenices. This episode has been fully recorded "online", and they had some funny "issues" with the recording, however, and besides some little jumps, delays, and pitch changes, they are confident that the sound quality is good enough and everybody enjoy this 1-hour episode. More in 2 weeks!
