The solar wind is a flow of particles that comes off the sun at about one million miles per hour and travels throughout the entire solar system. First proposed in the 1950s by University of Chicago physicist Eugene Parker, the solar wind is visible in the halo around the sun during an eclipse and sometimes when the particles hit the Earth’s atmosphere—as the aurora borealis, or northern lights.

The Giant Magellan Telescope announces fabrication of the sixth of seven of the world’s largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical telescope before.

MAROON-X instrument built by UChicago team measures its first planet.
In the past two decades, scientists have discovered more and more planets orbiting distant stars—but in some sense, they’re still just dots on a map.
“It’s kind of like looking at a map of Europe and seeing the dot that’s labeled ‘Paris,’” said University of Chicago astrophysicist Jacob Bean. “You know where it is, but there’s a whole lot that you’re missing about the city.”

Astrophysicist and University of Chicago graduate student Abigail Lee is the lead author on a new paper that analyzed observations of light from a nearby galaxy to validate the JAGB method for measuring cosmological distances. This novel technique will allow future independent distance measurements that can help answer one of the biggest outstanding questions in cosmology: how fast is the universe expanding?

Library staff, faculty, and students join forces to drive new astronomical discoveries
The University of Chicago Library continues to look to the sky in our ongoing collaborative work with Professor Rich Kron, Department of Astronomy and Astrophysics, exploring the use of data obtained from historical astronomical glass plates to drive new astronomical discovery. Since we last reported on the project in 2019 (“Mining historical glass slides for astronomical data”), a National Science Foundation grant, new collaborations, and detection of a likely supernova have furthered our work, strengthened our partnerships, and expanded our experiences and expertise.
