Astronomers Spot Double-Helix Structure in Messier 87

VLA image of the Messier 87 radio jet, made at multiple radio frequencies. The jet seen in this image is about 8,000 light-years long. This image clearly shows the corkscrew-like helical structure in the inner part of the jet, which originates at the bright spot at the left, at the core of the galaxy, where a supermassive black hole resides.

This artist’s illustration depicts what Chu et al. think is happening in the binary system KPD 0005+5106. The data suggest the white dwarf (blue sphere) is blasting a companion object (brown and red object on right), which is either a low-mass star or planet, with waves of heat and radiation. The white dwarf is also pulling material from the companion into a disk around itself, which the artist shows in orange, before it slams into its north and south poles. This process is contributing to the destruction of the companion through powerful gravitational forces. Image credit: NASA / CXC / M. Weiss / ASIAA / Chu et al.
