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.
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.
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.
The Joseph Weber Award for Astronomical Instrumentation is given for outstanding design, invention or significant improvement of instrumentation leading to advances in astronomy.
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.
UCLA professor Henry Kelly examines historical canonical legal procedures to correct the popular myths around the Italian astronomer’s belief in a sun-centered solar system.
The new observations confirm a long-standing theory that stars are copious producers of heavy elements.
The cutting-edge project that includes renowned scientists will tackle major challenges in the physical sciences, life sciences and engineering.
The team, led by a UCLA researcher, used NASA’s Hubble Space Telescope to gather data on Comet 332P as it broke apart 67 million miles from Earth.
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.
Viewers will have the rare opportunity to watch Mercury glide slowly across the sun.
Jura played a major role in advancing scholarship in his field and in shaping UCLA’s Division of Astronomy and Astrophysics over the course of four decades.
The violent impact with a “planetary embryo” called Theia occurred approximately 100 million years after the Earth formed, UCLA geochemists and colleagues report.
Jean-Luc Margot described a straightforward method that can be used to distinguish planets from other bodies like dwarf planets and minor planets.
A planet 100 light-years away that resembles a young Jupiter has been discovered by an international team of astronomers that includes six UCLA scientists.
Two UCLA astronomy professors are playing an important role in an international initiative to build the Cherenkov Telescope Array.
The astrophysicist is being honored by the UK academy for her 'acclaimed discoveries ... on the motions and nature of the stars orbiting the black hole in the centre of our Galaxy.'
The finding is a major advance because the high-energy particles can be harmful for satellites and humans in space.
NASA’s Dawn mission is observing the dwarf planet Ceres from 2,700 miles above its surface; the space agency has released new images and a video animation.
One of the new meteorites, found in Namibia and weighing in at 811 pounds, is now the largest meteorite in Los Angeles.
Cloud of newly forming stars has one billion times the luminosity of our sun, but is invisible in ordinary light
Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry puzzled scientists for many years.
