Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the Universe. These ‘newborns’ – observed as they appeared nearly 13 billion years ago – spun like a whirlpool, similar to our own Milky Way.

VLA observations have pointed to the most likely explanation for the phenomena that followed the violent collision of a pair of neutron stars in a galaxy 130 million light-years from Earth.

New ALMA observations push back the epoch of massive-galaxy formation even further by identifying two giant galaxies seen when the universe was only 780 million years old, or about 5 percent its current age.

ALMA discovers remarkably early signs of low-mass star formation near the supermassive black hole at the center the Milky Way.

New book tells the stories of four radio-astronomy pioneers who paved the way for today’s advanced observatories and also for some technologies that transformed our daily lives.

Dr. Ir. Omid Noroozian, an associate scientist and senior research engineer with NRAO’s Central Development Laboratory, was honored with NASA’s prestigious Nancy Grace Roman Technology Fellowship in Astrophysics. 

Astronomers using ALMA have discovered two rarely seen, distant galaxies spiraling in toward each other.
