A pair of images of a young star, made 18 years apart, has revealed a dramatic difference that is providing astronomers with a unique, ‘real-time’ look at how massive stars develop in the earliest stages of their formation.

Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety of mysterious phenomena visible only to radio telescopes.

For the first time, astronomers have caught a multiple-star system in the beginning stages of its formation, and their direct observations of this process give strong support to one of several suggested pathways to producing such systems.

Astronomers using the National Science Foundation’s Very Large Array (VLA) found surprisingly energetic activity in what they otherwise considered a ‘boring’ galaxy, and their discovery provides important insight on how supermassive black holes can have a catastrophic effect on the galaxies in which they reside.

 Looking back at the science news released by NRAO in 2014, the staff scientists at NRAO selected what they believed were the top 10 stories based on both scientific impact and public interest.

A new system that makes the Karl G Jansky Very Large Array two telescopes in one has been completed and its scientific operations are underway.

With the help of citizen scientists, a team of astronomers has found an important new example of a very rare type of galaxy that may yield valuable insight on how galaxies developed in the early Universe.

The VLA visitor center film, Beyond the Visible: The Story of the Very Large Array, received a prestigious Interpretive Media Award from the National Association for Interpretation (NAI).

Highly-detailed radio-telescope images have pinpointed the locations where a stellar explosion called a nova emitted gamma rays, the most energetic form of electromagnetic waves. The discovery revealed a probable mechanism for the gamma-ray emissions, which mystified astronomers when first observed in 2012.
