UArizona astronomers use DESI, which has observed more galaxies than any previous 3-D survey, to hunt for intermediate-mass black holes in small galaxies.
Since the arrival of NASA's James Webb Space Telescope at its orbital destination Jan. 24, the mission operations team has successfully powered on all of the telescope's science instruments, including its primary camera, UArizona's Near Infrared Camera. NIRCam will be used to align the telescope's 18 mirror segments so they work together as one.
Using observations of the nearby elliptical galaxy Centaurus A, a team of astronomers found an unprecedented number of possible globular clusters – old, dense groups of thousands of stars that all formed at the same time.
University of Arizona astronomers will help NASA's James Webb Space Telescope peer deeper into the universe than any telescope in history. Webb successfully launched on Christmas Day.
Researchers have identified the first signature of a magnetic field surrounding a planet outside of our solar system. Earth's magnetic field acts as a shield against energetic particles from the sun known as the solar wind. Magnetic fields could play similar roles on other planets.
The brightest comet of the year, named after the UArizona researcher who discovered it, is paying one last visit to Earth's neighborhood before leaving the solar system forever.
A team led by UArizona astronomers will use NASA's James Webb Space Telescope to examine three of the most distant active supermassive black holes known, as well as their host galaxies.
