Fusion target implosion on Nova. The green coloring of the target holder is due to the leftover laser light that was upconverted only "halfway" to UV, stopping at green. The optics are arranged to focus this light "short" of the target, and here it strikes the holder. A small amount of IR light is also left over, but this cannot be seen in this visible-light photograph. An estimate of the size of the implosion can be made by comparing the size of the target holder here with the image above.

…in this goal, the data it generated clearly defined the problem as being mostly a result of Rayleigh–Taylor instability, leading to the design of the National Ignition Facility, Nova's successor. Nova also generated considerable amounts of data on high-density matter physics, regardless of the lack of ignition, which is useful…

The target assembly for NIF's first integrated ignition experiment is mounted in the cryogenic target positioning system, or cryoTARPOS. The two triangle-shaped arms form a shroud around the cold target to protect it until they open five seconds before a shot.
