Quasars may answer how starburst galaxies were extinguished

Observations suggest quasars may starve galaxies of energy needed to form stars
University of Iowa astronomers have located quasars inside four dusty starburst galaxies. The discovery may explain why this type of galaxy, where huge numbers of stars were once created, ceased making stars.

UI graduate student in physics and astronomy builds instrument to study how northern lights are produced
Jim Schroeder, a graduate student in physics and astronomy, has built an instrument to study the physical principles that produce the northern lights. Schroeder will use his $126,000 fellowship from the National Science Foundation to test his instrument this month at UCLA.

CNBC The health risks of spending a year in outer space

A new report commissioned by NASA highlights many risks connected with putting more humans in space for longer periods of time. Those risks include muscle and bone loss, psychological health, and nutrition, Dr. Carol Scott-Conner, professor of surgery at the University of Iowa Carver College of Medicine, told CNBC.

What happened to the water on Mars?

UI researcher has instrument to test whether solar wind blew water out of ancient Martian atmosphere
With its empty channels and ghostly gullies, Mars resembles a planet once teeming with streams and flowing rivers. That begs the question: Where did all the water go? A University of Iowa space scientist aims to find out through an instrument on the Mars orbiter MAVEN.
