Observations with the National Science Foundation’s Very Large Array (VLA) have given scientists an unprecedented look into the atmosphere of Jupiter, revealing that features seen in visible light at the planet’s cloud surfaces have effects tens of kilometers downward.

Astronomers have used new capabilities of the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) to open a whole new realm of research into how galaxies evolve and interact with their surroundings over cosmic time.

Astronomers using an orbiting radio telescope in conjunction with four ground-based radio telescopes have achieved the highest resolution, or ability to discern fine detail, of any astronomical observation ever made.

New images of a young star made with the Karl G. Jansky Very Large Array (VLA) reveal what scientists think may be the very earliest stages in the formation of planets.

Astronomers have used some of the world’s most powerful telescopes to learn new details about collisions between massive clusters of galaxies.

A detailed study of young stars and their surroundings has produced dramatic new evidence about how multiple-star systems form and how the dusty disks that are the raw material for planets grow around young stars.

Using new images that show unprecedented detail, scientists have found that material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star.

Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light.

A study of spiral galaxies seen edge-on has revealed that “halos” of cosmic rays and magnetic fields above and below the galaxies’ disks are much more common than previously thought.

There may be fewer pairs of supermassive black holes orbiting each other at the cores of giant galaxies than previously thought.
