Radio Astronomy in the News
VLBA images detect orbital motion of two supermassive black holes as they circle each other at the center of a distant galaxy.
New evidence from the VLA suggests that a jet of material ejected by a young star may have triggered the formation of a second, younger star.
To make a star, the conditions inside interstellar gas clouds have to be “just right.” When it comes to a cloud’s magnetic fields, however, those conditions may range from powerful and orderly to weak and chaotic, new ALMA observations suggest.
Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.

Starless Cloud CoresThis image shows the ALMA data overlaid on an artist’s impression background. The ALMA data show two main cores as imaged by emission from the molecular ion N2D+ (two nitrogen and one deuterium atom). The core on the right is particularly bright and rounded, suggesting it is self-gravitating and poised to form a massive, single star – a very rare occurrence in star formation. The other core appears more distorted and fragmented, potentially leading to the formation of multiple lower-mass stars. This fragmentation is a normal process in star-forming clouds.
