GAAC Meeting, October 9 2020, with Robert Naeye and Finding Life on Other Worlds

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...

Perspective: The Case for Coordinating Earth & Space Science Education

In this essay, I argue in support of teaching the Earth & space sciences together, so that students can attain a more holistic understanding of their planetary environment, how it came to be, and where it is headed. Such teaching (and teachers) should receive the same priority as in the teaching of physics, chemistry, and biology.

Book Review: Alan Lightman’s The Accidental Universe, The World You Thought You Knew

There has always been a lot of conflict and contention between religion and science, arguably since the beginning of human abstract thought.

Earth and Space Report #2: Comparing Planetary Climates, and Why We Should Take Heed

Earth sits right in the Goldilocks zone. Venus, only a little closer to the sun, has a surface hot enough to melt lead, and Mars is cold enough to have dry ice -- C02 -- at its poles. What can the atmospheres of these three planets tell us about the future of our climate?

Why We Explore Earth and Space

I have no doubt that we will become an interplanetary species, within two decades and that we will likely find the existence of life, or past life, on another planetary body, within the next decade.

Extraterrestrial Anthropomorphism

Perhaps because of their tremendous popularity, Hollywood’s sci-fi films have exerted a powerful influence on our psyches – piquing our curiosity and igniting our imagination regarding life beyond Earth.

Dispatches from the Cosmonet

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.
