Carnegie Alum discusses JWST on C-Span as EPL scientists prepare their projects


Former Carnegie postdoctoral fellow Meredith MacGregor, now an Assistant Professor at the University of Colorado, joined Susan Swain on C-Span for a Q&A session on NASA’s James Webb Space Telescope. During the interview, MacGregor discusses how this new telescope will use infrared light to peer into the early development of our Universe. She also explains that scientists, like those at the Earth and Planets Laboratory, will use the telescope to probe and characterize the atmospheres of faraway planets.

Organic molecules found in a meteorite that hurtled to Earth from Mars were synthesized during interactions between water and rocks that occurred on the Red Planet about 4 billion years ago, according to new analysis led by Carnegie’s Andrew Steele and published by Science.  


Tracking down the forces that shaped our Solar System’s evolution

Meteorite Slice

Meteorites are remnants of the building blocks that formed Earth and the other planets orbiting our Sun. Recent analysis of their isotopic makeup led by Carnegie’s Nicole Nie and published in Science Advances settles a longstanding debate about the geochemical evolution of our Solar System and our home planet.


A letter from the new Director, Michael Walter

Michael Walter New Director Letter

In 2022, I will step into the role of Director at the Earth and Planets Laboratory (EPL). This is an exciting opportunity to help shape the future of EPL together with my colleagues, but it is also bittersweet because we are saying farewell to our Director, colleague, and friend Richard Carlson.
