Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Very Large Array, astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies.

Astronomers using a world-wide collection of telescopes have discovered the most prolific star factory in the Universe, surprisingly in a galaxy so distant that they see as it was when the Universe was only six percent of its current age.

The record-setting close approach of an asteroid on February 15 is an exciting opportunity for scientists, and a research team will use National Radio Astronomy Observatory and NASA telescopes to gain a key clue that will help them predict the future path of this nearby cosmic neighbor.

A new view of a 20,000-year old supernova remnant demonstrates the upgraded imaging power of the National Science Foundation’s Very Large Array and provides more clues to the history of this giant cloud that resembles a beloved endangered species, the Florida Manatee.

For the first time, astronomers have found a microquasar — a black hole devouring material from a companion star — in a galaxy beyond our own Milky Way.

Spectacular jets powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A illustrate the combined imaging power of two of astronomy’s cutting-edge tools, the Hubble Space Telescope’s Wide Field Camera 3, and the recently upgraded Very Large Array radio telescope in west-central New Mexico.

An unexpected discovery by astronomers using the National Science Foundation’s Very Large Array is forcing scientists to rethink their understanding of the environment in globular star clusters, tight-knit collections containing hundreds of thousands of stars.

Astronomers and officials from around the globe gathered on the high desert of New Mexico Saturday to officially bestow a new name on the world’s most famous radio telescope and to mark its transformation into a new and vastly more powerful tool for science.

Two new and powerful research tools are helping astronomers gain key insights needed to transform our understanding of important processes across the breadth of astrophysics.

The world’s most famous radio telescope will become the Karl G Jansky Very Large Array to honor the founder of radio astronomy, the study of the Universe via radio waves naturally emitted by objects in space.
