NASA’s largest telescope in space, JWST, is proving to be powerful enough to measure atmospheric chemicals on WASP-39b, a planet orbiting a star 700 light years away, and find sulfur dioxide, an element found in Earth’s ozone layer. “This is a mind-blowing demonstration of the capabilities of this telescope,” said Professor of Astronomy Seth Redfield, whose research group has been receiving early information from the telescope since its launch as a member of a JWST Early Release Science team. “There is a world that is hundreds of light years away and we can tell you how much sulfur dioxide is…

Martha “Marty” Gilmore, the George I. Seney Professor of Geology and professor of Earth and Environmental Sciences, has been awarded the 2022 Claudia J. Alexander Prize from the Division for Planetary Sciences of the American Astronomical Society (AAS) for her study of Venus’ geology. Gilmore is a Science Team Member on the DAVINCI and VERITAS missions to Venus, and the principal investigator of a Venus Flagship Mission Concept Study for the Planetary Decadal Survey. Gilmore’s work has “helped usher in a new decade of exploration of Venus with the selection of two new NASA Venus missions,” according to the AAS.…

NASA's new infrared telescope, which launched on Dec. 25, 2021, will help researchers like Wesleyan's Seth Redfield explore the universe in ways like never before. The James Webb Space Telescope (JWST), which is accessible to the worldwide scientific community, offers scientists the ability to explore the solar system, galactic evolution, the early universe, and the formation of stars and planets like never before. The telescope will also observe planets orbiting other stars, known as exoplanets. Professor of Astronomy Seth Redfield, a member of the JWST's Transiting Exoplanet Community Early Release Science Program (ERS), will work with scholars from around…

Using high-resolution data obtained from the Space Telescope Imaging Spectrograph aboard the Hubble Space Telescope, Wesleyan University Professor of Astronomy Seth Redfield can show the conditions the Sun encountered traveling through space over the past 5 million years. Redfield will present his findings Jan. 12, 2022 as part of a press conference associated with the American Astronomical Society’s previously planned annual conference. This work was a close collaboration of Redfield with Hunter Vannier ’20, and a major component of Vannier's senior thesis. Vannier is now a PhD student at Purdue University working on lunar mineralogy. By focusing on eight paths, each of…

By Maia Dawson '23 In the Lunar lab on the third floor of the Exley Science Center, Thomas Davoren MA ’22, thumbed through scientist David Walker’s handwritten notes from 1970, and inspected samples retrieved from the moon in 1969. Found in Davoren’s work are clues to the origins of Earth’s glowing satellite. Davoren was among the students awarded a Fall 2021 NASA Connecticut Space Consortium Fellowship. In a paper written for a conference in 2020 in Houston, Davoren detailed his discovery of Chromite-Ulvöspinel-Pyroxene (CUSP) inclusions. These unique, microscopic crystalline structures appeared first to Davoren in basaltic rocks retrieved from the…

Two proposed Venus mission concepts co-developed by planetary geologist Martha Gilmore were selected by NASA’s Discovery Program this week. The selected missions aim to understand how Venus became a scorching planet after it was potentially another habitable world in the solar system with an Earth-like climate. Gilmore, George I. Seney Professor of Geology, professor of earth and environmental sciences, is a co-investigator of both winning concepts. Each project will receive approximately $500 million per mission for development and is expected to launch in the 2028–2030 timeframe. The projects include VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) and DAVINCI+…

Martha Gilmore, George I. Seney Professor of Geology and professor of earth and environmental sciences, is the co-author of seven new papers and articles. These include: “Distinct Mineralogy and Age of Individual Lava Flows in Atla Regio, Venus Derived From Magellan Radar Emissivity,” published in the March 2021 issue of JGR: Planets. Gilmore's former postdoc Jeremy Brossier, Katie Toner '20 and Avi Stein '17 co-authored this paper. “The Venus Life Equation,” published online in the January 2021 issue of Astrobiology. “Variations in the radiophysical properties of tesserae and mountain belts on Venus: Classification and mineralogical trends,” published in the February…

For her exemplary contributions to research in the geological sciences and for being an instrumental mentor to young people of color, Professor Marty Gilmore received the 2020 Randolph W. “Bill” and Cecile T. Bromery Award from the Geological Society of America. Gilmore, George I. Seney Professor of Geology, professor of earth and environmental sciences, and co-coordinator of Wesleyan's Planetary Sciences program, was nominated for the award by Jim Head, the Louis and Elizabeth Scherck Distinguished Professor of Geological Sciences at Brown University. "Few individuals have done more for expanding diversity in the geosciences than Dr. Gilmore," Head said. She "leads…

Martha Gilmore, George I. Seney Professor of Geology and professor of earth and environmental sciences, is prominently featured in a recently released suite of five documentary films about the history, science, exploration, and possible settlement of the planet Venus. In the films, Gilmore, who is co-coordinator of planetary science at Wesleyan, along with other experts in a range of fields, help to illuminate and elucidate the fascinating history and possible future of the second planet from the sun, commonly known as Earth's "sister planet." The suite of films was produced by filmmaker and space exploration advocate Dave Brody P '24.…

If a spacecraft were to quickly travel outside the solar system—potentially en route to a nearby exoplanetary system—it would need to pass through an atmosphere unfamiliar to scientists on Earth. As a recipient of a $415,000 grant from NASA, Seth Redfield, chair and associate professor of astronomy, hopes to learn more about the mysterious makeup of this "outer space." "There are several very early designs for an interstellar probe, but first, we need to understand the properties of the space in between the stars if you are traveling through it, especially at high speed," Redfield said. "Given the vastness of…

Not one, but two spacecraft mission concepts co-developed by Martha Gilmore, George I. Seney Professor of Geology and professor of earth and environmental sciences, received second-round backing from NASA's Discovery Program on Feb. 13. Both concepts—which were awarded $3 million each—would assess whether Venus was ever a habitable planet by examining its landscape, rocks, and atmosphere. NASA's Discovery Program, now in its ninth year, funds investigations to develop concept studies for new missions. Although they’re not official missions yet, the selections focus on compelling targets and science that are not covered by NASA’s active missions or recent selections. Gilmore's projects…

Research conducted by a Wesleyan professor is part of a new space show at the American Museum of Natural History. Martha Gilmore, George I. Seney Professor of Geology and professor of Earth and environmental sciences, worked over the past year developing content for the new Hayden Planetarium Space Show Worlds Beyond Earth. The show opened on Jan. 21 as part of the museum's 150th anniversary celebration. "It’s amazing," Gilmore says. "The images that you see are all realistic. We even contacted some of the engineers for the Magellan spacecraft in order to understand exactly how the spacecraft imaged Venus in…
