UCLA Ph.D. student Andy Tay writes about a crucial a challenge to long-distance space travel — overcoming the long-term effects of microgravity on our bodies.

An international team of astronomers has observed a striking spiral pattern in the gas surrounding a red giant star called LL Pegasi and its companion star 3,400 light-years from Earth.

A “baby” solar system 300 light-years away has given astrophysicists from UCLA and the Carnegie Institution for Science a rare peek at the formation of a planet.

The UCLA Department of Earth, Planetary, and Space Sciences presents a talk by from William Borucki, principal investigator of NASA's Kepler mission.

A UCLA-led team of scientists discovered a white dwarf star in the constellation Boötes whose atmosphere is rich in carbon, nitrogen, oxygen and hydrogen.

UCLA’s Jonathan Aurnou and collaborators in Marseille, France, demonstrated that the planet’s jets likely extend thousands of miles below its visible atmosphere.

A UCLA-led research team reports that the moon is at least 4.51 billion years old and probably formed only about 60 million years after the birth of the solar system — 40 million to 140 million years earlier than had been thought.

The new observations confirm a long-standing theory that stars are copious producers of heavy elements.

Scientists from the Institute for Planets and Exoplanets will offer free views of the moon from the roof of the Mathematical Sciences Building.

New findings by a UCLA-led team of researchers answer a question about our space environment and will help scientists protect telecommunication and navigation satellites.

COSMOS-1908 is 12 billion light years away, which is “by far” the most distant galaxy scientists have accurately measured oxygen abundance in.

Kepler-62f could have atmospheric compositions that allow it to be warm enough to have surface liquid water, which would make it possible for the planet to support life.

The researchers made the discovery using an effect called gravitational lensing to see the incredibly faint object, which was born just after the Big Bang.

The August 2017 expedition to Swan Valley Idaho is presented by UCLA Alumni Travel, which was launched 75 years ago for sojourners who share a passion for learning.
