A new report that could make it simpler to send spacecraft to some areas of Mars while still protecting the planet from Earth-based contamination was presented today at a press conference at the 53rd annual meeting of the American Astronomical Society's Division for Planetary Sciences by Planetary Science Institute Senior Scientist Amanda Hendrix.

Earth's rapidly changing Arctic coastal regions have an outsized climatic effect that echoes around the globe. Tracking processes behind this evolution is a daunting task even for the best scientists.

An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research.

The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent papers involving scientists from the University of California, Davis, use data from meteorites derived from Vesta to resolve the "missing mantle problem" and push back our knowledge of the solar system to just a couple of million years after it began to form. The papers were published in Nature Communications Sept. 14 and Nature Astronomy Sept. 30.

UNLV researchers and colleagues may have identified the first known planet to orbit three stars.
