Dr. Brittany Miles joins faculty at Steward Observatory, advancing UofA’s legacy in infrared instrumentation innovation

“Executing ambitious observational programs is key to pushing the boundaries of our understanding of planetary atmospheres,” said Dr. Brittany Miles, who will be joining the faculty of the UofA Department of Astronomy and Steward Observatory this fall. “Arizona has provided me with resources, facilities, and long-term stability to support the development and execution of these goals.”

New York Times: ‘More Than a Hint’ That Dark Energy Isn’t What Astronomers Thought

Using the Dark Energy Spectroscopic Instrument, or DESI, scientists have assembled the largest three-dimensional map of the universe to date.

James Webb Space Telescope reveals unexpected complex chemistry in primordial galaxy

This infrared image from NASA’s James Webb Space Telescope was taken by the onboard Near-Infrared Camera for the JWST Advanced Deep Extragalactic Survey, or JADES, program. The NIRCam data was used to determine which galaxies to study further with spectroscopic observations. One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.3, making it the current record-holder for most distant known galaxy. This corresponds to a time less than 300 million years after the big
