A growing baby planet photographed for first time in a ring of darkness
Using a cutting-edge optics system developed at the University of Arizona, researchers have gotten a glimpse of what our solar system likely looked like during its infancy.
Alpha Centauri, sun's closest stellar neighbor, likely harbors giant planet
New observations that U of A astronomers helped make with the James Webb Space Telescope solidify previous hints of a giant planet orbiting the sun's closest neighbor.
U of A astronomers celebrate first look at the universe from the Vera C. Rubin Observatory
The first images from the Vera C. Rubin Observatory mark a proud milestone for the University of Arizona, whose Richard F. Caris Mirror Lab is the only facility in the world capable of crafting the telescope's unique mirror.
Giant Magellan Telescope advances to National Science Foundation final design phase
Built with mirrors manufactured by the University of Arizona, one of the world's largest optical telescopes clears key milestone toward U.S. federal construction support.
Revealing the lives of planet-forming disks
New observations of 30 planet-forming disks – the birthplaces of planets around stars – reveal in greater detail than ever how gas and dust behave over time and shape the evolution of exoplanet systems.
In the belly of the beast: Massive clumps reveal star factories from a bygone era of the cosmos
Astronomers have identified massive, dense star factories, unlike any found in the Milky Way, providing a rare glimpse into processes shaping galaxies in the very early universe.
NASA selects rocket for U of A-led Aspera mission
NASA has selected Rocket Lab USA Inc. to launch the agency's Aspera mission early next year. Led and managed by the U of A, Aspera will study galaxy evolution through observation of ultraviolet light.
A vast molecular cloud, long invisible, is discovered near solar system
Astronomers have discovered an enormous cloud of gas and dust, containing the fundamental building block of stars and planets. Dubbed Eos, the molecular cloud is one of the largest single structures in the sky.
Study sheds light on ancient solar activity using radiocarbon locked in tree-rings
Analyzing radiocarbon in tree-ring samples, scientists have created the most detailed record yet of solar activity during the first millennium B.C.E.
