The spiral of the Southern Pinwheel

    From NOIRLab, Feb. 8, 2021: The Dark Energy Camera, originally used to complete the Dark Energy Survey, has taken the most detailed photo of Messier 83, also known as the Southern Pinwheel galaxy. (In DECam’s second act, scientists can apply for time to use it to collect data that is then made publicly available.) In all, 163 DECam exposures went into creating this image.

    Why astronomers are interested in this mysterious signal

      From CNN, Feb. 4, 2021: Fermilab scientist Don Lincoln contextualizes a recent signal that some think may be a sign of extraterrestrial intelligence, explaining the hubbub around the recent a transmission originating from Proxima Centauri. With hope for hearing such a signal one day and pride for humanity’s legacy of looking skyward, Lincoln cautions against reading too much into this transmission, which hasn’t yet been vetted with scientific review.

      UK scientists build core components of global neutrino experiment

      Engineers and technicians in the UK have started production of key piece of equipment for a major international science experiment. The UK government has invested $89 million in the international Deep Underground Neutrino Experiment. As part of the investment, the UK is delivering a series of vital detector components built at the Science and Technology Facilities Council’s Daresbury Laboratory.

      By measuring light from individual stars between galaxy clusters, astronomers find clues about dark matter

        From Universe Today, Feb. 3, 2021: Recent published results from the Dark Energy Survey point to intracluster light — feeble light from rogue stars that don’t belong to a galaxy — as a potential pathway to measure dark matter. Fermilab scientist Yuanyuan Zhang contextualizes the findings.

        Astronomers explore ‘cosmic balance’ to weigh clusters of galaxies

          From Super Interessante, Jan. 31, 2021: A team of researchers from Fermilab and the National Observatory in Brazil used the light of solitary stars to calculate the mass of some of the largest structures in the cosmos — galaxy clusters. In addition to taking the most detailed measurement ever published of intracluster light, the team’s new method of measurement can help further investigate dark matter.

          Exploring the unanswered questions of our universe with quantum technologies

            From University of Birmingham, Jan. 13, 2021: Fermilab will take part in an international collaboration, led by Cardiff University, on quantum-enhanced interferometry for new physics. The project’s four table-top experiments may help explore new parameter spaces of photon-dark matter interaction, and seek answers to the long-standing question at the heart of modern science: How can gravity be united with the other fundamental forces?
