An artist’s impression of what a massive galaxy in the early universe might look like. The galaxy is undergoing an explosion of star formation, lighting up the gas surrounding the galaxy. Thick clouds of dust obscure most of the light, causing the galaxy to look dim and disorganized, very different from galaxies seen today. (Image: James Josephides/Christina Williams/Ivo Labbe)
The early universe is filled with monsters, a new study revealed. Researchers led by astronomer Christina Williams discovered a previously invisible galaxy, and perhaps a new galaxy population waiting to be discovered.

The University of Arizona Insect Collection is collaborating with Pima Community College students and the Arizona-Sonora Desert Museum to catalog every native species of bee in Tucson and the surrounding Sonoran Desert.
Artist’s impression of the quasar 3C 279, based on observations that included the Submillimeter Telescope, or SMT, in Arizona. Powered by supermassive black holes, quasars are among the brightest objects known. With a mass about one billion times that of the sun, this quasar is so far from Earth that its light has taken more than 5 billion years to reach us. (Image: ESO/M. Kornmesser)

Astronomy Prof Peter Behroozi was awarded a Packard Fellowship to get to the bottom of a long-standing mystery: How could supermassive black holes grow so big so quickly after the Big Bang?

A University of Arizona researcher and a UA alumnus are part of the team that is the first to sequence the genome of the Florida panther, and they’ve found evidence of increased genetic variation in the population.
In the semi-arid forests of the western U.S., increases in rainfall extremes – wetter wet years and drier dry years – can lead to long-term declines in tree growth, even with no change in average precipitation. (Deborah Lee Soltesz/CC 1.0 Universal)

Extreme rainfall variability may cause long-term declines in tree growth for many trees in the western U.S., including the ponderosa pine, Douglas-fir, piñon pine and bur oak.
