Pointing to the Poles of Brown Dwarfs: Polar Vortex Possibilities

Pointing to the Poles of Brown Dwarfs: Polar Vortex Possibilities

The AAS Nova featured a nice article by Lexi Gault on our new paper in which Fuda Nguyen and I propose that the polar regions of brown dwarfs (and most gas giant exoplanets) are different from the equatorial and mid-latitude regions: The poles are in a different circulation regime (vortex-dominated) – this means that they have different…

Bioverse and Identifying Sciences for Exoplanet Surveys in the Next Decades

Bioverse and Identifying Sciences for Exoplanet Surveys in the Next Decades

Exoplanet science is one of the most rapidly expanding fields of modern physical sciences: Countless new measurements are made, thousands of papers published annually, and the number of exoplanets and planet candidates discovered is rapidly approaching 6,000 – and set to accelerate! What really drives this discovery? What will the future of exoplanet science bring? Which…

Honored to be elected a AAAS Fellow!

I am honored to be elected a 2023 Fellow of the American Association for the Advancement of Science, the world’s largest general scientific society, in recognition of my “distinguished contributions to the field of astrobiology and astrophysics, particularly for advancements in understanding of habitable exoplanets and planetary systems.” The prestigious AAAS Fellows program is over 150…

Bolder than Webb?

Bolder than Webb?

January 2024: “Bolder than Webb?” Former NASA Administrator Dan Goldin’s OpEd in Aerospace America makes a strong statement on the importance of inspiring, bold visions for next-generation NASA missions. Goldin argues that the current path will lead to a decade(s)-long gap in major improvements of space telescope capabilities, which poses a substantial risk for American leadership in space…

Crotts Radical Hypothesis Lecture 2022

Crotts Radical Hypothesis Lecture 2022

During an exciting visit to Columbia University’s Department of Astronomy, I have the opportunity to deliver the 2022 Crotts Radical Hypothesis Lecture. The lectures honor the memory of Arlin Crotts, a brilliant and visionary astrophysicists, whose work and discoveries profoundly influenced many fields of modern astrophysics: From dark matter haloes through light echoes to the…

Atmospherica featured in UA News

An excellent article by Mikayla Mace Kelley from UA News on our team’s work on using a scalable biotechnology solution to remove atmospheric carbon dioxide. Read about how we combine astrobiology, biosystems engineering, and ecology for a novel approach to mitigating a global challenge. Small but mighty: How UArizona professors are harnessing the power of…
