Five thousand eyes on the skies: Scientists choreograph robots to observe distant galaxies

July 6, 2020 sarah Jonas ASTROPHYSICS, Cosmology, Dark Energy, dark energy spectroscopic instrument, DESI

Scientists have begun operating the Dark Energy Spectroscopic Instrument, or DESI, to create a 3-D map of over 30 million galaxies and quasars that will help them understand the nature of dark energy. The new instrument is the most advanced of its kind, with 5,000 robotic positioners that will enable scientists to gather more than 20 times more data than previous surveys. Researchers at Fermilab helped develop the software that will direct these positioners to focus on galaxies several billion light-years away and are currently in the process of fine-tuning the programs used before the last round of testing later this year.

Drones Help Calibrate Radio Telescope at Brookhaven Lab

June 25, 2020 sarah Jonas Brookhaven National Laboratory, Cosmology, Dark Energy, dark matter, Drone, Prototype

Cosmologists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are experimenting with a prototype radio telescope, called the Baryon Mapping Experiment (BMX). Built at the Lab in 2017, the prototype serves as a testbed for managing radio interference and developing calibration techniques. Lessons learned from the prototype could pave the way for Brookhaven to develop a much larger radio telescope in collaboration with other national Labs, universities, and international partners.

Meteorites lend clues to origins of earliest history of solar system

December 16, 2019 sarah Jonas 0 Comments Astronomy, Cosmology, Planets, Solar system, Space, SUN, Universe

Lawrence Livermore National Laboratory (LLNL) scientists and a collaborator from the University of Münster reviewed recent work that shows how meteorites exhibit a fundamental isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC – rocks or sediments containing carbon or its compounds) groups, which most likely represent material from the inner and outer solar system.
