Harnessing the exquisite sensitivity of the GBT, astronomers have given one of Einstein’s predictions on gravity its most stringent test yet. By precisely tracking the meanderings of three stars in a single system – two white dwarf stars and one ultra-dense neutron star – the researchers determined that even the most massive of objects “fall” in the same manner as their less-dense counterparts.
Years-long observation program surprises astronomers with evidence of a star’s violent death near the core of a distant galaxy.
Two independent teams of astronomers have uncovered convincing evidence that three young planets are in orbit around an infant star known as HD 163296. Using a new planet-finding strategy, the astronomers identified three discrete disturbances in a young star’s gas-filled disk: the strongest evidence yet that newly formed planets are in orbit there.
ALMA detects signature of oxygen from galaxy 13.28 billion light-years away
An important milestone was reached with the publication of the 1000th peer-reviewed paper using ALMA data.
NRAO’s CDL led the development of a new and improved version of a Phased Array Feed.
