Astronomy Picture of the Day (APOD) has an image of a star which turns out to be a double star, seen only with telescopic aid. It includes the visible spectrum of both stars which shows how different the two stars are.
The image is lovely and the explanation adds to the pleasure of seeing it as well as in not misunderstanding what you are seeing.
For stargazers, planet watchers, the constellation savvy, the scientific term "asterism" is well known. I'd never heard of it --not included in the explanation which gave me an idea of what a common term it is -- and Wiki explains the term. The explanation also includes a comment on how astronomers/astrophysicists reason.

Lava Study: Lab and Field

This video (11m 45s) from #ScienceInsider is about how scientists study lava. Of course they collect samples but how and where? There is more to the study of volcanology than doing field work. There is the laboratory, too and I very much like how the video bring field and lab work together.
The Syracuse University Lava Project is included and represents the laboratory side of the study-of-lava equation, science practices in action. An interesting aspect of the Lava Project is that it is a result of a collaboration between sculptor Bob Wysocki (SU Department of Art) and geologist Jeff Karson (SU Department of Earth Sciences). The page is well worth taking a look at.

Animals and Earth Quake Predictions

The second of two presentations by Sabine Hossenfelder on earthquake prediction, she discusses short-term forecasts, "from months to seconds. In this one she again calls attention to their human toll. "[E]arthquakes are the most fatal natural disasters. In the two decades from 1998 to 2017, they killed more than 700 thousand people." Then she asks,
"So what are seismologists doing to warn people of earthquakes? Can animals sense if an earthquake is coming? And what are earthquake lights? That’s what we will talk about today. ... Short-term predictions don’t help with infrastructure investments, but they give people time to evacuate."
The non-seismic precursors may attract your attention because those involving animals are commonly reported. First, Hossenfelder includes a discussion of several short-term physical precursors "that are fairly well established though not all are well understood before she turns her attention to animals.
She ends by talking about the "heavy burden" that comes with predictions, i.e., when they are wrong. She makes a suggestion that seem a worthy and important component of any prediction.
The video can be watched on YouTube but I like being able to read the text along with listening.
