An astronomer studying small irregular galaxies discovered a remarkable feature in one galaxy that may provide key clues to understanding how galaxies form and the relationship between the gas and the stars within galaxies.

Astronomers have discovered three brown dwarfs — enigmatic objects that are neither stars nor planets — emitting radio waves that scientists cannot explain. The three newly-discovered radio-emitting brown dwarfs were found as part of a systematic study of nearby brown dwarfs using the National Science Foundation’s Very Large Array radio telescope.

When the European Space Agency’s Huygens spacecraft makes its plunge into the atmosphere of Saturn’s moon Titan on January 14, radio telescopes of the National Science Foundation’s National Radio Astronomy Observatory will help international teams of scientists extract the maximum possible amount of irreplaceable information from an experiment unique in human history.

Astronomers using the National Science Foundation’s Very Large Array radio telescope to study the most distant known quasar have found a tantalizing clue that may answer a longstanding cosmic chicken-and-egg question.

Making an extra effort to image a faint, gigantic corkscrew traced by fast protons and electrons shot out from a mysterious microquasar paid off for a pair of astrophysicists who gained new insights into the beast’s inner workings and also resolved a longstanding dispute over the object’s distance.

Astronomers using the National Science Foundation’s Very Large Array have overcome longstanding technical hurdles to map the sky at little-explored radio frequencies that may provide a tantalizing look deep into the early Universe.
