A new solar telescope in Hawaii has captured images of the sun unlike any seen before. Professor Robert Rosner, an astrophysicist at the University of Chicago and one of the lead investigators on the project, says he’s been waiting for almost 40 years to see images like the ones recently captured.

The Laboratory Astrophysics Division (LAD) of the American Astronomical Society (AAS) is awarding its 2020 Laboratory Astrophysics Prize to Dr. James Truran of the University of Chicago. This prize is given for his theoretical work on early star formation and the nucleosynthesis history of the universe, as well as for his seminal contributions to the study of astrophysical thermonuclear explosions, nucleosynthesis, and the use of nuclear-decay chronometers to determine ages of stellar and terrestrial matter.

When NASA’s James Webb Space Telescope launches in 2021, one of its most anticipated contributions to astronomy will be the study of exoplanets—planets orbiting distant stars. Among the most pressing questions in exoplanet science is: Can a small, rocky exoplanet orbiting close to a red dwarf star hold onto an atmosphere?
In a series of four papers in the Astrophysical Journal, a team of astronomers proposes a new method of using Webb to determine whether a rocky exoplanet has an atmosphere. The technique, which involves measuring the planet’s temperature as it passes behind its star and then comes back into view, is significantly faster than more traditional methods of atmospheric detection like transmission spectroscopy.
“We find that Webb could easily infer the presence or absence of an atmosphere around a dozen known rocky exoplanets with less than 10 hours of observing time per planet,” said Jacob Bean of the University of Chicago, a co-author on three of the papers.

Congratulations to UChicago Astronomy & Astrophysics Professor Jacob Bean, who is the new NASA science team lead for CASE!
NASA will contribute an instrument to a European space mission to explore the atmospheres of hundreds of exoplanets.
The instrument, called the Contribution to ARIEL Spectroscopy of Exoplanets, or CASE, adds scientific capabilities to ESA's Atmospheric Remote-sensing Infrared Exoplanet Large-survey, or ARIEL, mission.

University of Chicago professor Wendy Freedman and colleagues have a new measurement for the rate of expansion in the modern universe, suggesting the space between galaxies is stretching faster than scientists would expect. The paper, “An Independent Determination of the Hubble Constant Based on the Tip of the Red Giant Branch,” Freedman et al, was published on July 12, 2019, in The Astrophysical Journal.
