Stephen Markham, the latest Tombaugh Scholar at New Mexico State University, is delving into the seismology of giant planets such as Jupiter, Saturn, and Uranus. Markham's research adds a new dimension to the studies of atmospheric phenomena at the giant planet cloud tops conducted at NMSU's astronomy department.
According to Nancy Chanover, an astronomy professor at NMSU, Markham's research brings excitement to the field, stating, “Steve Markham’s research on the interiors and deep atmospheres of the giant planets adds an exciting dimension to the previous and ongoing studies of atmospheric phenomena at the giant planet cloud tops that have been done in the NMSU astronomy department.”
Markham, who is supported by the endowed fund established by Clyde Tombaugh, the renowned astronomer who discovered Pluto, expressed his admiration for Tombaugh, saying, “I really looked up to Clyde Tombaugh. It inspired me to believe that maybe someday I could try to do something similar. I think that definitely played a role in my career trajectory.”
Delving into his research focus on Jupiter quakes, Markham explained, “So it sounds a little weird, but on Earth, seismology happens with earthquakes, but on the sun and with giant planets, you can have the whole planet oscillating and that tells you information about their interior structure.”
Markham's work extends beyond the solar system to exoplanets, particularly those with hydrogen atmospheres. He emphasized the importance of understanding how convection and weather operate on planets with hydrogen atmospheres, noting the potential for habitable planets with vastly different climates from Earth.
Regarding the search for extraterrestrial life, Markham expressed an open-minded approach, stating, “There’s a lot of emphasis in astronomy on trying to find places where we might find life that looks like ours...It’s important to cast a wide net.”
Reflecting on his roots in Las Cruces and the influence of the local astronomy community, Markham highlighted the impact of growing up in a town with a strong astronomy presence. He expressed gratitude for the opportunity to research distant planets while raising his child close to family.
Markham's journey from Las Cruces to renowned research institutions and back home as the Tombaugh Scholar showcases the interconnectedness of his personal history, scientific curiosity, and professional endeavors. As he delves into the depths of giant planets, Markham's work stands to influence not only the field of astronomy but also future generations of students intrigued by the mysteries of the cosmos.
