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.

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.

Astronomers using a global combination of radio telescopes to study a stellar explosion some 30 million light-years from Earth have likely discovered either the youngest black hole or the youngest neutron star known in the Universe.

Twenty years ago, astronomers discovered a number of enigmatic radio-emitting filaments concentrated near the center of the Milky Way Galaxy.

Astronomers have discovered a key signpost of rapid star formation in a galaxy 11 billion light-years from Earth, seen as it was when the Universe was only 20 percent of its current age.

A Fourth of July fireworks display features bright explosions that light the sky with different colors, yet all have the same cause.

Astronomers studying the most distant quasar yet found in the Universe have discovered a massive reservoir of gas containing atoms made in the cores of some of the first stars ever formed.

An international team of astronomers has discovered that a young galaxy had a central disk of gas in which hundreds of new stars were being born every year — at a time when the Universe was only a fraction of its current age.
