The sharp radio “vision” of the VLBA gives astronomers a detailed look at a galaxy as it appeared when the Universe was a small fraction of its current age, giving clues about conditions at that early time.
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.
