of more than 200 scientists, researchers know it's not extraterrestrials, but
space dust that's
causing the erratic and extreme dips in brightness around Tabby's star.
- The giant radio telescopes
of NASA's Deep
Space Network — which perform radio and radar astronomy research in addition to their communications functions — were tasked with observing radio emissions from Jupiter's radiation belt, looking for disturbances
caused by comet
dust.
Even larger objects, known as moonlets, were suspected to be disrupting the ring in such a way as to
cause periodic jets
of dust to shoot hundreds
of kilometers into
space.
The process could be driving vast amounts
of gas and
dust toward the coalescing black hole, in turn
causing intense energy to billow out from the object, says Neil Gehrels, a physicist at NASA's Goddard
Space Flight Center in Greenbelt, Maryland, and a member
of the research team.
Or said differently the amount
dust per cubic

cause it to vacuum clean a different part
