Colaprete did not offer definitive word as to why the visual camera apparently did not detect the event but added there were interesting changes in spectroscopic data taken by the spacecraft that might have been
produced by a debris cloud.

If sunlight must penetrate the dust covering a comet's water ice in order to warm it and
produce jets, Sunshine says the Deep Impact findings suggest the ices on such dormant comets may not have run out but merely become sealed —
by layers of
debris, for example.
Instead, physicists must search through the
debris of many different types of particle decay to find precise combinations of
by - products that the Higgs would
produce — and different chains of particle decays may well have the same signatures.
It consists of derelict satellites, rocket bodies and parts, and small fragments
produced by collisions between
debris.
The EUSO telescope, which will be used to find
debris, was originally planned to detect ultraviolet light emitted from air showers
produced by ultra-high energy cosmic rays entering the atmosphere at night.
The aftermath of the neutron star collision detected in August included the gravitational waves spotted
by LIGO and VIRGO (pale arcs); a near - light - speed jet that
produced gamma rays (magenta); expanding
debris from a kilonova — an explosion similar to a supernova, but smaller — that
produced ultraviolet (violet), optical and infrared (blue - white to red) emission; and X-rays (blue).
Instead, the two photons could represent part of the
debris produced by the decay of a potentially much more massive particle.
The smaller
debris / meteoroids
produced get spread around the orbit quite quickly (read: centuries or millennia)
by various physical effects (ejection speeds from the comet; radiation pressure; Poynting - Robertson effect; Yarkovsky effect).
Given that Tau Ceti does not appear to be a young star, the ring of dusty
debris is believed to be
produced by collisions between larger comets and asteroids that break them down into smaller and smaller pieces, and Tau Ceti's disk is similar in size and shape to the disk of comets and asteroids that orbits the Sun, Sol.
According to the researchers, this pattern is the result of stellar
debris colliding with itself (which
produces bursts of optical and UV light), and heating up just before being swallowed
by the black hole (which gives off X-ray flares).
Although it can not be excluded that these excesses are
produced by coincidental alignment of background galaxies, statistical arguments suggest that at least some of them are true
debris discs.
After these living cells feed off the nutrients delivered through the bloodstream, they
produce metabolic
debris that is then carried away
by the lymphatic fluid, also known as lymph.
The digestion of sebum also
produces bacterial
debris, metabolic
by - products, and fatty acids which are all inflammatory.
Infection usually
produces a characteristic dark discharge; in some cases, the ear canal can become entirely obstructed
by this coffee ground - like
debris.
This vast video work was created using scenery - generation software employed
by the film and gaming industries in combination with technical data from NASA's missions to Mars to
produce a faithful artist's rendering of Martian terrain, populated
by the
debris from centuries of exploration.
Enviva claims that it
produces wood pellets only from low - grade wood resources such as chips, bark, sawdust
by - products, treetops, branches, and other forestry
debris remaining after the tree trunks from commercial forests have been shipped for construction material.
