Magnetic tornadoes create Earth-size spots discovered at Jupiter's poles
While Jupiter’s Great Red Spot has been a constant feature of the planet for centuries, a team of astronomers have discovered equally large spots at the planet’s north and south poles that appear and disappear seemingly at random.

Professor J. Xavier Prochaska to deliver December 4 Kraw Lecture
The Kraw Lecture Series aims to help audiences better understand the big picture behind scientific research at UC Santa Cruz and the broader trends at play. This tradition continues with the December 4 talk on how artificial intelligence (AI) is accelerating the scientific pursuit.

Team discovers ultra-massive galaxies in early Universe that challenge standard cosmology
An international team of astronomers has identified three ultra-massive galaxies—each nearly as massive as the Milky Way—already in place within the first billion years after the Big Bang. The discovery is surprising because it indicates that the formation of stars in the early Universe was far more efficient than previously thought, challenging current models of galaxy formation.

Ultra-small spectrometer yields the power of a 1,000 times bigger device
UC Santa Cruz researchers are designing new ways to make spectrometers that are ultra-small but still very powerful, to be used for anything from detecting disease to observing stars in distant galaxies

Astronomy postdoc to develop technologies that mold starlight to better detect exoplanets
The Astronomy & Astrophysics Department welcomes postdoctoral scientist Emiel Por, who invents technologies that mold the starlight captured by ground- and space-based telescopes to improve imaging of planetary companions. His work will be supported by the Heising-Simons Foundation's 51 Pegasi b Fellowship program.

A wobble from Mars could be sign of dark matter, new study finds
New simulations suggest that there are enough primordial black holes—potential dark matter candidates—in the universe for one to pass through the inner solar system every decade. The work builds upon an astrophysical theory that has growing popularity.

Scientists to study nearby galaxies for galactic-formation history, dark matter
At approximately 100,000 light years in diameter, the Milky Way's vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history. UC Santa Cruz astronomer Puragra "Raja" GuhaThakurta sums up this dilemma in more familiar and figurative terms: "We simply don’t have a selfie stick long enough to take those kinds of photos."

Annual event at Lick Observatory links modern astronomy to native perspectives
In collaboration with the UC Santa Cruz American Indian Resource Center, the University of California Observatories (UCO) recently hosted the second annual Native Star Stories Night at Lick Observatory. Held this year on May 9, the special event is intended to show that this traditional way of engaging with the cosmos remains as relevant and valuable today to indigenous communities as it was thousands of years ago.

UC Santa Cruz astrophysicists honored for advancing research on the mysterious FRB
Fast radio bursts are sudden flashes of radio waves coming from random parts of the sky. Each one is on only for a few milliseconds, but they are extraordinarily bright: In those few milliseconds, they put out more energy than our sun does in an entire year. We also know that they come from objects in distant galaxies, sometimes billions of light years away.

Hydrothermal vents on seafloors of ‘ocean worlds’ could support life, new study says
Many lines of research suggest that some ocean worlds release enough heat internally to drive hydrothermal circulation under their seafloors. This heat is generated by radioactive decay, as occurs deep in the Earth, with additional heat possibly generated by tides.

Ph.D. student leads effort to open Kosovo's first observatory
Earth’s newest observatory will open to the public on June 20, 2024, coinciding with the summer solstice, thanks in large part to a UC Santa Cruz student from Kosovo who discovered her love of astronomy as a child amidst the chaos of the country’s brutal war for independence over 20 years ago.

Earliest, most distant galaxy discovered with James Webb Space Telescope
An international team of astronomers today announced the discovery using NASA’s James Webb Space Telescope (JWST) of the two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the Big Bang.

New exoplanets catalog showcases diverse, exotic worlds
Our understanding of exoplanets, those strange worlds that orbit stars beyond our solar system, is now broader and deeper thanks to separate studies published this week featuring the work of researchers at UC Santa Cruz.

UC Santa Cruz ‘Shadow the Scientists’ program honored for astronomical DEI efforts
A science-inclusion program based at UC Santa Cruz that has allowed thousands of school-age children, educators, and inquisitive individuals to look through world-class telescopes alongside trained astronomers has been honored for opening up scientific exploration to those from underrepresented backgrounds around the world.

First results from DESI make the most precise measurement of our expanding universe
We now have the largest 3-D map of our cosmos ever created, thanks to DESI—a powerful instrument mounted atop a telescope in Arizona with a robotic array of 5,000 fiber-optic “eyes” that look into the night sky.
