The Dark Energy Survey has released a massive, public collection of astronomical data and calibrated images from six years of work. Containing data on nearly 700 million astronomical objects, this second data release in the Survey s seven-year history is the topic of sessions today and tomorrow at the 237th Meeting of the American Astronomical Society.[1]
Building a Giant 2D Map of the Universe to Prepare for the Largest 3D Map
Nearly 200 researchers pitched in to gather, process, and stitch together images for half of the sky to prepare for the start of the Dark Energy Spectroscopic Instrument’s observations

This video describes the monumental effort that went into constructing a 2D map of the universe to prepare for the Dark Energy Spectroscopic Instrument, which will produce the largest-ever 3D map of the universe. The final data release for the preparation of this 2D map, known as Data Release 9 or DR9, was distributed Jan. 13. (Credit: Marilyn Sargent/Lawrence Berkeley National Laboratory)

When I became director of the U.S. National Science Foundation (NSF) in June 2020, the world was in the midst of a pandemic that continues to reshape daily lives, work, education, and the research enterprise. As we enter 2021 with the promise of suppressing COVID-19, the world looks to the science and engineering community for solutions to speed global recovery. To generate the solutions needed from all sectors of science and engineering, the United States must create a vigorous culture of innovation nationwide, leverage public-private partnerships to tackle complex research questions, and align exploratory research with societal impacts.
New Semiconductor Detector can Identify Radioactive Isotopes with High Resolution
Written by AZoOpticsDec 8 2020
In groundbreaking new research, an international team of researchers led by the University of Minnesota Twin Cities has developed a unique process for producing a quantum state that is part light and part matter.
The discovery provides fundamental new insights for more efficiently developing the next generation of quantum-based optical and electronic devices. The research could also have an impact on increasing efficiency of nanoscale chemical reactions.
The research is published in
Nature Photonics, a high-impact, peer-reviewed scientific journal published by the Springer Nature Publishing Group.
Quantum science studies natural phenomena of light and matter at the smallest scales. In this study, the researchers developed a unique process in which they achieved ultrastrong coupling between infrared light (photons) and matter (atomic vibrations) by trapping light i
