The association, which is the world’s largest scientific society, honored the UCLA faculty members for their efforts to advance science or its applications.

The director of the Keck Observatory writes about how the UCLA astrophysicist overcame the doubters en route to her Nobel Prize.

Ghez, who received the prize for her research into black holes, is the eighth UCLA faculty member to be named a Nobel laureate.

Previous simulations suggested that astronauts on the surface would be safe during a full moon while it resides within the magnetosphere.

Margaret Kivelson has been recognized by the Royal Society, Harvard University and University of Leicester.

Images of C/2019 Y4 breaking into more than two dozen fragments in recent days were captured by the Hubble Space Telescope.

Co-author Andrea Ghez says the objects look like gas and behave like stars.

The object is a magnetic structure that covers an enormous region of some 160 light-years.

UCLA’s David Jewitt said the data provides the best measure of the size of the comet's nucleus, “which is the really important part.”

A new method used to study planets’ geochemistry implies that Earth is not unique.

Comet 2I/Borisov is the first interstellar comet to be observed by astronomers.

“We have never seen anything like this in the 24 years we have studied the supermassive black hole,” said UCLA professor Andrea Ghez.

Does the physicist’s theory tell the full story? A detailed analysis of a star’s orbit near supermassive black hole gives a look into how gravity behaves.

UCLA astronomer Mark Morris and an international team of collaborators found that the two plumes extend over 500 light-years.

At the heart of the dispute is the Hubble constant, a number that relates distances to the redshifts of galaxies — the amount that light is stretched as it travels to Earth.

A team of scientists that includes two UCLA College researchers published a study in Nature Communications that sheds light on the phenomenon.

“It was a rare case in astronomy where two competing models ... offered precisely opposite predictions,” said UCLA professor Steven Furlanetto.

Scientists have long been interested in Europa because evidence suggests that a vast ocean lies beneath its icy outer shell.

“I’ve been studying young stars near Earth for 20 years and I’ve never seen anything like this one,” said UCLA astronomer Benjamin Zuckerman.

Titan’s liquid methane rain appears to play a major role in shaping its icy surface, and the downpours are much more common than researchers expected.

The astronomers identified a “special comet” called K2 traveling from beyond Saturn’s orbit — the farthest active inbound comet ever seen.

Andrea Ghez is an astronomy professor and pre-eminent scholar on the role of black holes in the evolution of galaxies.

The new hypothesis doesn’t rely on the “unlikely coincidences” that underpin other theories explaining primordial black holes.

More than 1,000 people filled the Court of Sciences on Monday to view the partial eclipse of the sun.

Scientists had assumed the core was rotating at about the same speed as the surface, but this surprising observation might reveal what the sun was like when it formed.
