It took three sky surveys to prepare for a new project that will create the largest 3-D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion. This Dark Energy Spectroscopic Instrument project will explore this expansion, driven by a mysterious property known as dark energy, in great detail. The surveys, which wrapped up in March, have amassed images of more than 1 billion galaxies and are essential in selecting celestial objects to target with DESI, now under construction in Arizona.

A lot of people say they would like to travel to Mars, but Zoe Townsend doesn’t just talk the talk. As a mechanical engineer at CERN, she knows the importance of putting ideas to the test. To see if she could actually handle the unique challenges posed by living and doing science on another planet, Townsend spent 12 days on a simulated Mars mission in the deserts of Utah.

From CNN, June 21, 2019: Fermilab scientist Don Lincoln talks about the recent UFO sightings in the news. It’s plausible that what pilots have been seeing is something with an ordinary explanation, whether it be an instrumental glitch or some other unexplained artifact.

Particle accelerators are some of the most complicated machines in science. In today’s more autonomous era of self-driving cars and vacuuming robots, efforts are going strong to automate different aspects of the operation of accelerators, and the next generation of particle accelerators promises to be more automated than ever. Scientists are working on ways to run them with a diminishing amount of direction from humans.

For over two decades, Spanish institutions have been collaborating with Fermilab. From the Tevatron era to the lab’s current neutrino experiments, Spain has made important contributions.

Scientists at SLAC National Accelerator Laboratory are building the world’s largest digital camera for astronomy and astrophysics — a minivan-sized 3200-megapixel “eye” of the future Large Synoptic Survey Telescope that will see light in 2022. In the meantime, the lab has completed its work on a miniature version that will soon be used for testing the telescope and taking LSST’s first images of the night sky. ComCam will help test the observatory once it is installed in Chile later this year.

From Science News, June 17, 2019: The particles could be spotted when they slam into electrons or atomic nuclei in the crystals, says Fermilab scientist Noah Kurinsky.

From Physics World, June 14, 2019: Symmetry magazine’s physics slang roundup is mentioned in this piece.

What do particle accelerators and craggy outcrops have in common? Both have Tor Raubenheimer trotting the globe. Thanks to both his work at SLAC National Accelerator Laboratory and his passion for rock climbing, he has gotten to know people and places on several continents.

From University of Cincinnati News, June 13, 2019: University of Cincinnati researchers search for subatomic particles called ‘sterile neutrinos,’ which could redefine the Standard Model.
