It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.

The MicroBooNE detector – a so-called time projection chamber filled with 170 tons of liquid argon – spotted neutrinos that were generated when proton beams from Fermilab’s accelerator complex slammed into a target a few hundred yards away from the detector.

Researchers from Department of Energy’s SLAC National Accelerator Laboratory are developing tools for the acquisition of the experiment’s data and for the reconstruction of...

Researchers have reported the detection of the farthest object yet, galaxy EGS8p7. At >13.2 billion years old, it provides a fascinating glimpse of the very early universe, just 600,000 years after the Big Bang.

Earlier this year, EGS8p7 had been identified as a candidate for investigation based on Hubble and Spitzer data. Using the multi-object spectrometer for infrared exploration (MOSFIRE) at the W.M...
