Astronomers have caught the fleeting explosion of a Type Ia supernova in detail. Understanding how they form could have implications for dark energy measurements.
"Synthetic observations" simulating nascent planetary systems could help explain a puzzle — how planets form — that has vexed astronomers for a long time.
UA astronomer Kate Su talks about her experience aboard the "jetliner observatory" SOFIA. Su and her team confirmed that a nearby star system resembles our solar system in its youth.
From a pool of eight proposed missions competing for funding in NASA's Explorer category, the space agency has chosen to fund the UA-led GUSTO mission. The goal of the $40 million endeavor is to send a balloon to near-space, carrying a telescope that will study the interstellar medium.
The appointment of Robert Shelton is further evidence of the UA's central role in the Giant Magellan Telescope — the first of a new crop of extremely large observatories tasked with studying the first stars and galaxies in the universe and the exploration of planets orbiting other stars.
A team led by UA astronomer Vishnu Reddy has characterized the smallest known asteroid using Earth-based telescopes. Asteroid 2015 TC25 measures just 6 feet across.
Research by two UA planetary scientists reveals fascinating clues about Pluto, suggesting that the small world at the solar system's fringe is much more active than anyone imagined.
Research led by UA professor Renu Malhotra provides additional support for the possible existence of such a world and narrows the range of its parameters and location.
UA professor Bill Boynton has contributed to 10 NASA missions in his lifetime, including OSIRIS-REx, which began its journey to the asteroid Bennu last month. But this month, Boynton can’t help but think about Mars and the Odyssey mission, celebrating its 15th anniversary.
The conference is the largest international civil-military conference dedicated to space surveillance. The UA's prominence reinforces its lead in the emerging space surveillance industry.
