A five-year quest to map the universe and unravel the mysteries of dark energy began officially on May 17, 2021, at Kitt Peak National Observatory near Tucson, Arizona. The Dark Energy Spectroscopic Instrument (DESI) will capture and study the light from more than 30 million galaxies and other distant objects, allowing scientists to construct a 3-D map of the universe with unprecedented detail.
DESI is an international science collaboration that includes physicists from the University of Utah and is managed by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) with primary funding from DOE’s Office of Science.
A new map of dark matter in the local universe reveals several previously undiscovered filamentary structures connecting galaxies. The map could enable studies about the nature of dark matter as well as about the history and future of our local universe.

The cause of Earth s deepest earthquakes has been a mystery to science for more than a century, but a team of Carnegie scientists may have cracked the case. New research published in AGU Advances provides evidence that fluids play a key role in deep-focus earthquakes which occur between 300 and 700 kilometers below the planet s surface.
Fossil seed-bearing structures preserved in a newly discovered Early Cretaceous silicified peat in Inner Mongolia, China, provide a partial answer to the origin of flowering plants, according to a study led by Prof. SHI Gongle from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS).
