In 1969, UA scientists were the first to detect the optical flash from a pulsar — a stellar corpse thought to pack at least one-and-a-half times the mass of our sun into a neutron star.

The awards keep coming for Robert C. Kennicutt Jr., who was recently honored by both the National Academy of Sciences and the Royal Astronomical Society.

Astronauts who embarked on spaceflights lasting longer than six months experienced a decrease in the functionality of NK cells, which play an important role of the immune system by killing cancerous cells and preventing viruses from reactivating.

Two UA-managed telescopes have aided in the serendipitous discovery of the brightest quasar ever seen in the early universe, which suggests there could be more waiting to be discovered.

An international team led by Teddy Kareta, a doctoral student at the UA's Lunar and Planetary Laboratory, investigated (3200) Phaethon, a bizarre asteroid that sometimes behaves like a comet, and found it even more enigmatic than previously thought.

In a new study by UA planetary scientists, observations prove that ice volcanoes on the dwarf planet Ceres generate enough material to fill one movie theater each year.

Researchers in the UA Lunar and Planetary Lab are eagerly awaiting the launch of the Parker Solar Probe, the first attempt to get close to the sun and study the solar wind at its source.

Data obtained by a clever technique that can detect light echoes hint at why Eta Carinae, the most luminous and massive star in the Milky Way, erupted like a supernova, yet survived.

University of Arizona astronomy students searched 101 massive clouds of gas to find those that may be in the first phases of forming massive stars.

Scientists from around the world are working on the NASA Curiosity rover mission. What makes the UA's Mars Science Laboratory team unique is undergraduate student Gordon Downs.
