This edition combines fun and science as only Dr. Waller can do, as we take a colorful look at what's going on in supposedly empty space between the stars in the Milky Way galaxy.
This January, the American Astronomical Society held its big annual meeting completely online. The Covid-19 pandemic ruled out the society’s planned gathering in Scottsdale, AZ but the AAS pivoted by opening-up digital access to thousands of astronomers across the United States and around the world. More than 3,000 registrants were listed in the online portal, thus demonstrating that the vital communication of astronomical research, education, and public outreach could carry on in this alternative format.
If the Big Bang theory is correct, how fast is the universe expanding? Astronomers are facing a troubling disconnect between different methods used to measure the expansion rate, known as the Hubble constant. The two methods are giving similar but slightly different rates. Either one method is providing inaccurate results, or there is some kind of unknown physics operating in the universe.

Are we alone or do we share our solar system and galaxy with other forms of life? And how widespread are advanced civilizations with whom we could communicate? Right now we don’t have answers to these profound questions. But scientists are in hot pursuit...
It is tempting to say that any well-educated person should know what it takes to be scientifically literate. But what does scientific literacy really involve? Given that scientific literacy is a key goal of most science education standards and frameworks, considerable ink has been dedicated to utilizing the term in pedagogical papers.
