Hubble Ultra Deep Field 2014
The Hubble Ultra Deep Field displays nearly 10,000 galaxies across the observable Universe in both visible and near-infrared light. The smallest, reddest galaxies are among the youngest known, existing when the Universe was just 800 million years old.
To get this image, the Hubble Telescope focused its camera for 10 days on a very tiny, apparently empty region of sky. The area it focused on was about the size of the head of a pin, if a pin was held at arms-length.
They chose the direction due to the lack of foreground stars in our own galaxy; in that way they were able to observe out into the inter-galactic medium with minimal interference and view up to 13.2 billion light years away in time and space. Really they were looking into the large-scale structure of the universe which resembles something like this:

L-3 Warrior Systems Ground Panoramic Night Vision Goggle (GPNVG)
L-3 Warrior Systems, the night vision division of L-3, has developed and fielded one of the biggest innovations in night vision technology with the Ground Panoramic Night Vision Goggle (GPNVG-18). The purpose of the GPNVG-18 is to provide the operator more information under goggles, allowing him to more quickly move through the OODA Loop (Observe, Orient, Decide, Act).
The most striking feature of the GPNVG-18 is the presence of four separate image intensifier tubes with four separate objective lenses arrayed in a panoramic orientation. The center two lenses point forward like traditional dual-tube goggles, giving the operator more depth perception, while two more tubes point slightly outward from the center to increase peripheral view. The two tubes on the right and the two on the left are spliced at the eyepieces. The operator sees the two center tubes somewhat overlapping the two outer tubes to produce an unprecedented 97° FOV. This is an absolute game-changer for the SOF community.
The two right and two left tubes are housed in merged assemblies and are hung from a bridge similar to ANVIS goggles, giving operators interpuplliary adjustment options. They can also be easily removed and operated as independent handheld viewers. The Bridge assembly features fore/aft adjustment on a ratchet system and can come configured from the factory in two different variants for different helmet mount setups: Ball Detent (ANVIS) or Dovetail (BNVS).

30mm AHEAD Shrapnel Shell
AHEAD stands for Advanced Hit Efficiency And Destruction
This round is filled with 152 tungsten cylinders weighing 3.3 grams each.
This round, like most shrapnel rounds, is designed to explode just before reaching it’s target, thereby scattering the tungsten cylinders in a cone pattern. The tungsten shrapnel continues forward at extreme speed and impacts the target over a much broader area than a regular round would effect. Because it causes moderate damage over a wide area this round is particularly well suited for point defense, ie, shooting down incoming missiles and aircraft that get too close.
The fuse (which is located just behind the tungsten cylinders) is essentially just a really accurate timer. The timer is set wirelessly via coils built into the gun immediately before each individual round is fired. Although I wasn’t able to find a very comprehensive guide on this round, I image they also adjust the timer to control the spread of shrapnel for different targets. Detonating the round sooner, further from the target, would cause a wider spread of shrapnel but do less damage per area. Whereas detonating the round later, closer to the target, would cause a tighter spread of shrapnel and do more damage per target area.
