Saturn’s tiny, frozen moon Enceladus is a strange place. Just 300 miles across, the moon is thought to have an outer shell of ice covering a global ocean 20 miles deep, encasing a rocky core. Slashed across Enceladus’ south pole are four straight, parallel fissures or “tiger stripes” from which water erupts. These fissures aren’t quite like anything else in the solar system.
Three faculty members of the College of Letters and Science are among the 10 UC Davis faculty elected to the 2019 class of fellows of the American Association for the Advancement of Science for their scientifically or socially distinguished efforts to advance science or its applications. The new fellows are Jiming Jiang, professor of statistics; Thomas C.M. Lee, professor of statistics; and Sarah Stewart, professor of earth and planetary sciences.
A new study from Caltech and the UC Davis College of Letters and Science shows that giant impacts can dramatically lower the internal pressure of planets, a finding that could significantly change the current model of planetary formation.
On July 20, 1969, Apollo 11 touched down on the moon and Neil Armstrong became the first human to set foot on the lunar surface. The moon rocks brought back to Earth launched a new era of research about the moon’s origin. Fifty years later, researchers at the UC Davis College of Letters and Science continue to discover new aspects of the moon’s formation that further our understanding of the solar system. Here are some highlights of their research.
As our solar system was forming nearly four and a half billion years ago, a planet-sized object struck the early Earth, leading to the formation of the moon, possibly from a hot, spinning cloud of rock vapor called a synestia. But after the Earth and moon had condensed from the vapor, there was another phase of growth as meteorites crashed into both bodies.
Since landing in 2012, NASA’s Curiosity rover has been collecting data about the geology and chemistry of the Martian surface. As a member of NASA’s Mars Science Laboratory, geology professor Dawn Sumner helps plan the route Curiosity takes as it explore ancient environments in Gale Crater.
With a terrain covering volcanoes, steaming fumaroles and forestlands, the Lassen Field Station is the newest addition to the University of California, Davis’ Natural Reserve System. The partnership offers researchers access to a variety of park facilities such as cabins, classroom space and camping. The reserve will streamline the research permit process and open new avenues for research, teaching and public outreach.
