An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting “cosmic dawn” — the era after the Big Bang when stars first ignited and galaxies began to bloom.

By measuring the polarization of light emitted when a star is spaghettified, UC Berkeley graduate student Kishore Patra and professor Alex Filippenko deduce the shape of the debris cloud left behind.Read more about The ultimate fate of a star shredded by a black hole

A team of astronomers led by UC Berkeley graduate student Casey Lam and associate professor Jessica Lu has for the first time discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object’s strong...Read more about Astronomers may have detected a ‘dark’ free-floating black hole

UC Berkeley astronomers used AI to find unsuspected connections hidden in the complex mathematics arising from general relativity — in particular, how that theory is applied to finding new planets around other stars.Read more about AI reveals unsuspected math underlying search for exoplanets

NASA’s latest and snazziest satellite, the James Webb Space Telescope (JWST), launched on Christmas Day, deployed its 21-foot-wide mirror a mere two weeks ago and reached its orbital destination earlier this week. With a flashy new telescope now nearly a reality, astronomers at the...Read more about Berkeley astronomers to put new space telescope through its paces

Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but with more precise data has come a conundrum: Estimates based on measurements within our local universe don’t agree with extrapolations from the era shortly after the Big Bang 13.8 billion years ago....Read more about How fast is the universe expanding?
