Death and Birth of Stars

Astronomers have used the National Science Foundation’s Very Long Baseline Array radio telescope to make the first-ever time-lapse movie showing details of gas motions around a star other than our Sun.

Astronomers have found evidence for the most powerful magnetic field ever seen in the universe. They found it by observing a long-sought, short-lived afterglow of subatomic particles ejected from a magnetar — a neutron star with a magnetic field billions of times stronger than any on Earth and 100 times stronger than any other previously known in the Universe.

Radio telescope studies of the fiery afterglow of a Gamma Ray Burst have provided astronomers with the best clues yet about the origins of these tremendous cosmic cataclysms since their discovery more than 30 years ago.

A team of astronomers says that observations with the National Science Foundation’s Very Large Array radio telescope show that a neighboring bloated star has giant convective plumes propelling gas from its surface up into the star’s atmosphere.

A team of astronomers using a pair of National Science Foundation radio telescopes has made the first measurements of the size and expansion of a mysterious, intense fireball resulting from a cosmic gamma ray burst last May.

Radio astronomers revealed that the first gamma-ray burster ever detected at radio wavelengths has surprised them by its erratic behavior.
