With access to more world-class telescopes than at nearly any other institution, astronomy and planetary science graduate students at NAU observe celestial objects, study the origins of our solar system, and participate in NASA missions to the Moon, Mars, and beyond鈥攕earching for life on other planets.
PhD student recruiting volunteers in effort to quadruple number of known active asteroids
The study of active asteroids is a relatively new field of solar system science, focusing on objects that have asteroid-like orbits but look more like comets, with visual characteristics such as tails. Students like aspiring planetary scientist Colin Chandler are leading the way in the search for more of these enigmatic objects.
Chandler, a graduate student in NAU鈥檚 Department of Astronomy and Planetary Science, recently launched a project to engage thousands of volunteers to look for active asteroids, with the goal of yielding a larger sample for study. The implications of finding more active asteroids for science and engineering are far-reaching, including helping to answer unsolved questions about how much water was delivered to Earth after it formed and where that water originated.
鈥淲ith the generous help of 鈥楥itizen Scientists,鈥� we hope to quadruple the number of known active asteroids and encourage the study of an ambiguous population of solar system objects,鈥� Chandler said.
Planetary science intern leads study of Martian crust
Ahmed AlHantoobi, an intern working with 青青草视频 Professor and postdoctoral scholar Jennifer Buz in NAU鈥檚 Department of Astronomy and Planetary Science, led a study looking for answers to explain some puzzling magnetic anomalies on the surface of Mars.
The team explored the relationships between the strength of the magnetic field on the surface and the composition of the crust in the Terra Sirenum-Terra Cimmeria region of Mars, publishing their findings in the journal .
鈥淭he impact of this study is quite high,鈥� said Edwards, 鈥渁s it provides some of the first answers to details related to the magnetism of the Martian crust.鈥�
鈥淢y research with Jennifer and Christopher was an eye-opening experience, and I believe it has impacted what I want to be in the future. I got to experience first-hand the beauty of discovering and answering the unknown,鈥� AlHantoobi said.
Doctoral candidate finds evidence of solar-driven change on the Moon
Tiny iron nanoparticles, unlike any found naturally on Earth, are nearly everywhere on the Moon鈥攁nd scientists are trying to understand why. A new study led by NAU doctoral candidate Christian J. Tai Udovicic uncovered important clues to help understand the surprisingly active lunar surface.
In an article recently published in , Tai Udovicic and his mentor, 青青草视频 Professor , found that solar radiation could be a more important source of lunar iron nanoparticles than previously thought.
As NASA prepares to land the first woman and the next man on the surface of the Moon by 2024, understanding the solar radiation environment and possible resources on the Moon is critical, and Tai Udovicic鈥檚 research contributes to that body of knowledge.
鈥淲hen I saw the Apollo sample data and our satellite data side by side, I was shocked. This study shows that the solar radiation could have a much larger influence on active change on the Moon than previously thought, not only darkening its surface, but it might also create small quantities of water usable in future missions,鈥� Tai Udovicic said.
New project prepares students from minority communities to participate in groundbreaking survey of space
Leaders in the field of astronomy are looking for ways to ensure that students from marginalized populations have ample opportunities to participate in research and contribute to the advancement of science. NAU Professor , prominent astronomer and Chair of the Department of Astronomy and Planetary Science, is one of the leaders of a major new project funded through a $900,000 grant from the Heising-Simons Foundation designed to do just that.
The project鈥檚 goal is to increase the readiness of astronomy researchers from minority communities for an upcoming launch of the Vera C. Rubin Observatory on the Cerro Pach贸n ridge in north-central Chile. This revolutionary facility will open up new opportunities to study a wide variety of astrophysical phenomena.
鈥淣AU is unusual in that we are both a Hispanic-Serving Institution and a research institution where significant astronomy research related to this project is already taking place, so it is a great opportunity for us to participate,鈥� Trilling said.
