Jordan Bretzfelder, a UCLA doctoral student, proposed the idea while completing a summer internship at the Lunar and Planetary Institute in Houston.

Could the very timing of a mission help shield astronauts from dangerous radiation?

Fifteen years of radar measurements by a UCLA-led team have provided critical data for understanding many of the planet’s fundamental properties.

How the fourth woman to win the prize in physics found the answer to a mystery in the stars.

The UCLA planetary scientist is deputy principal investigator for one of the NASA rover’s experiments.

In her talk, the UCLA astrophysicist answers the question, “How do you observe something you can’t see?” among many others.

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.

Stories on women in STEM, dentistry and Henry Samueli.

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.
