- Astronomers have discovered the most distant quasar yet found — a cosmic monster more than 13 billion light-years from Earth powered by a supermassive black hole more than 1.6 billion times more massive than the Sun and more than 1,000 times brighter than our entire Milky Way Galaxy. https://public.nrao.edu/news/quasar-new-distance-record/ 19 comments science
- Astronomers have spotted a massive disk galaxy, not unlike our own, that formed 12.5 billion years ago when our 13.8 billion-year-old universe was only a tenth of its current age. The galaxy's disk has a mass of 70 billion times that of our sun. It's also rotating at 170 miles per second https://public.nrao.edu/news/alma-discovers-massive-rotating-disk-in-early-universe/ 9 comments science
- Astronomers have made the first-ever observations of a circumplanetary disk, the planet-girding belt of dust and gas that astronomers strongly theorize controls the formation of planets and gives rise to an entire system of moons. https://public.nrao.edu/news/2019-alma-circumplanetary/ 12 comments science

- Astronomers may be close to solving a 30-year-old mystery: identifying the source of a faint infrared glow that permeates the Milky Way and other galaxies. The molecule responsible may be benzonitrile, an intriguing organic molecule that helps to chemically link carbon-based molecules. https://public.nrao.edu/news/2018-gbt-chemistry/ 4 comments science
- Astronomers have detected traces of methyl chloride, or Freon-40, surrounding infant stars and the comet 67P/Churyumov-Gerasimenko, suggesting it forms naturally in interstellar clouds. The findings quash the hope that some researchers had that the compound might signal the presence of life. https://public.nrao.edu/news/2017-alma-stars-comet/ 15 comments science
