About this Image

VLBA image of the star TX Cam, showing regions ("spots") of maser emission from Silicon Monoxide (SiO) molecules forming a shell around the star. Approximate size of the star is indicated by red circle (artifically added to image). The maser spots are where the SiO molecules are amplifying radio emission at a frequency of 43 GHz. In separate images made at different times, these maser spots are seen to move.

Investigator(s):  Athol Kemball and Philip Diamond
