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.
Pulsar Bursts Coming From Beachball-Sized Structures
In a major breakthrough for understanding what one of them calls ‘the most exotic environment in the Universe,’ a team of astronomers has discovered that powerful radio bursts in pulsars are generated by structures as small as a beach ball.
Astronomers Trace Microquasar’s Path Back in Time
Astronomers have traced the orbit through our Milky Way Galaxy of a voracious neutron star and a companion star it is cannibalizing, and conclude that the pair joined more than 30 million years ago and probably were catapulted out of a cluster of stars far from the Galaxy’s center.
Surprising Image Revises Understanding Of Dwarf Galaxies
An intensive study of a neighboring dwarf galaxy has surprised astronomers by showing that most of its molecular gas — the raw material for new stars — is scattered among clumps in the galaxy’s outskirts, not near its center as they expected.
Young Star Probably Ejected From Triple System
Astronomers analyzing nearly 20 years of data from the National Science Foundation’s Very Large Array radio telescope have discovered that a small star in a multiple-star system in the constellation Taurus probably has been ejected from the system after a close encounter with one of the system’s more-massive components, presumed to be a compact double star. This is the first time any such event has been observed.
Giant Radio Jet Coming From Wrong Kind of Galaxy
Giant jets of subatomic particles moving at nearly the speed of light have been found coming from thousands of galaxies across the Universe, but always from elliptical galaxies or galaxies in the process of merging — until now.
