Images of C/2019 Y4 breaking into more than two dozen fragments in recent days were captured by the Hubble Space Telescope.
UCLA is tied for fifth in the number of professors honored this year as early-career scientists and scholars who are rising stars of science.
Co-author Andrea Ghez says the objects look like gas and behave like stars.
Magnetic storms originate closer to Earth than previously thought, threatening satellites.
UCLA astrophysicist Smadar Naoz’s research indicates that if there is a second black hole, it would have a mass at least 100,000 times that of the sun.
UCLA began observing its 100th birthday and delivered new advances in research, health care, the arts, community service and teaching.
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.
UCLA astronomer Bradley Hansen on how a giant exomoon hundreds of times the size of Earth might help astronomers find planets where life may thrive.
If skies are clear, viewers will be able to see the moon — approximately 240,000 miles from Earth — and its many craters in great detail.
“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.
The research addresses a longstanding question: Why does the moon have so much less ice than Mercury, despite their similar surface conditions?
The UCLA-developed sensors work at room temperature, unlike current technology that needs extreme cold.
High pressure deep inside the young Earth may have driven vast stores of carbon into the planet’s core while also setting the stage for diamonds to form.
Magnetic pump built by Bruin Space launches on Blue Origin reusable rocket.
UCLA astronomer Mark Morris and an international team of collaborators found that the two plumes extend over 500 light-years.
Vladimir Vassiliev, professor of physics and astronomy, has served as principal investigator on project that could help address questions in very-high-energy astrophysics.
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.
The free event will include moon dust, meteorites and lunar experts. The viewing is part of International Observe the Moon Night, an annual worldwide celebration that encourages appreciation of the moon.
With the successful launch of their ELFIN satellites, UCLA students’ work studying space weather is just beginning.
For the past five years, more than 250 UCLA undergraduates have designed and built a small satellite that will launch into orbit to study space weather.
A team of scientists that includes two UCLA College researchers published a study in Nature Communications that sheds light on the phenomenon.
