Our exciting new results on TESS observations of the atmospheric dynamics of the closest brown dwarfs are out! Here is a link to the Astrophysical Journal paper that describes the findings. Thanks to Mimmo Nardiello’s mastery of the TESS data, we could present an amazing rich lightcurve on the closest brown dwarf system to the…
The American Institute for Aeronautics and Astronautics‘ ASCEND2020 event was an exciting amalgam of governmental groups, entrepreneurs, academia, aerospace corporations, and everyone interested in Space 2.0 and the new economic opportunities it may bring along. With over 3,000 attendees from 32 countries and 1,300 organizations, it has been a fascinating event to attend. I was…
Excited to announce our new paper on the information contained in the age-dependence of biosignatures in samples of broadly earth-like planets. Our paper – that appeared on arXiv a few hours ago and is in press at the Astrophysical Journal – explores two important questions: 1) If we detect possible biosignatures in an exoplanet survey,…
Can we detect atmospheric biosignatures in the next two decades? Only if we can meet a major, newly-recognized challenge to our studies of exoplanet atmospheric composition. Over the past years the Hubble Space Telescope has proven to be our most powerful tool to probe the atmospheres of transiting exoplanets: the comparison of spectra taken before…
Our new paper came out today in Science, presenting evidence for bands, zones, spots, and waves in brown dwarfs and a model that explains well several until-now mysterious changes in the brightnesses of brown dwarfs. Podcast: Learn more about our project from the Science Magazine’s podcast! I am excited about our results because they open a new…
