Solving a 30-year-old problem in high mass star formation

Some 30 years ago, astronomers found that regions of ionized gas around young high mass stars remain small (under a third of a light-year) for ten times longer than they should if they were to expand as expected in simple ...

New studies give strong boost to binary-star formation theory

(Phys.org) —Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery gives strong ...

Writing the history of the 'Cosmic Dark Ages'

For millions of years after the Big Bang, there were no stars, or even galaxies to contain stars. During these "Cosmic Dark Ages," neutral hydrogen gas dominated the universe. When clouds of primordial hydrogen gas started ...

Astronomers use precision pulsar positions to break record

An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from ...
