About this Image

This VLA image of the x-ray and radio-emitting star SS 433 is in the Milky Way Galaxy. It is reasonably close to the Earth, hence we can study it in great detail.

    Technical Caption Galactic: Radio/X-Ray Star. This VLA image of the x-ray and radio-emitting star SS 433 is in the Milky Way Galaxy. It is reasonably close to the Earth, hence we can study it in great detail. In particular, we find that the regions of radio emission seen here are being expelled from the star at nearly one-third the speed of light. From month-to-month and even from day-to-day, the shape of the radio image changes as a result of these rapid motions. Since SS 433 looks like the bright radio galaxies with its relativistic jets of radio emission we presume that the physics of these objects is also similar. The changes we can see in SS 433 probably happen over centuries in the radio galaxies; this makes SS 433 a "Roseta Stone" for the physics of radio sources.
