Sarah Stewart, professor of earth and planetary sciences at UC Davis, will discuss planetary collisions and the discovery of a new type of astronomical object at a public lecture supported by the Winston Ko Professorship in Science Leadership. Stewart’s presentation will be “A New Creation Story for the Earth and Moon.”
A team of UC Davis students has placed first overall in the First Nations Launch competition sponsored by NASA and the Wisconsin Space Grant Consortium.
Two rising stars in the sciences have received prestigious CAREER awards from the National Science Foundation (NSF). The NSF Faculty Early Career Development (CAREER) program recognizes junior faculty who conduct outstanding research, are excellent educators and include education or community outreach in their work.
Some of the Milky Way’s oldest stars have been spotted in a surprising place — the disk that is our galaxy’s youngest region. Supercomputer simulations of their orbits suggest these metal-poor stars came from a smaller galaxy that slammed into the Milky Way more than 7 billion years ago.
Astronomers are getting a look at the dusty part of the distant universe with a huge field of telescopes in the high, dry Atacama desert of Chile. New results are telling us about the structure of the distant universe and yielding surprises about the evolution of galaxies.
The Atacama Large Millimeter/submillimeter Array, or ALMA, collects infrared light, so astronomers can learn more about distant galaxies as well as picking up objects that they could not see at all in the visible or ultraviolet spectrum.
According to Einstein’s theory of General Relativity, gravity is curvature in the fabric of spacetime. Shockwaves can distort spacetime, causing singularities where the laws of physics appear to break down.
Now two mathematicians at UC Davis have come up with equations that remove these singularities. In doing so, they also extend a theorem called Uhlenbeck Compactness to the setting of General Relativity.
University of California, Davis, will be part of a new National Science Foundation Physics Frontier Center focusing on understanding the physics and astrophysical implications of matter under pressures so high that the structure of individual atoms is disrupted.
Warm, cold, just right? Physicists at the University of California, Davis, are taking the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe.
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.
Happy anniversary Hubble! The world’s first large space telescope was launched April 24, 1990. Here are a few cool findings from UC Davis researchers who use the Hubble Space Telescope.
