As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. In this image, planetary nebula NGC 7027 resembles a jewel bug, an insect with a brilliantly colorful metallic shell.
Recently, NGC 7027's central star was identified in a new wavelength of light — near-ultraviolet — for the first time by using Hubble's unique capabilities. The near-ultraviolet observations will help reveal how much dust obscures the star and how hot the star really is.
This object is a visibly diffuse region of gas and dust that may be the result of ejections by closely orbiting binary stars that were first slowly sloughing off material over thousands of years, and then entered a phase of more violent and highly directed mass ejections.
Hubble first looked at this planetary nebula in 1998. By comparing the old and new Hubble observations, researchers now have additional opportunities to study the object as it changes over time.
Planetary nebulas are expanding shells of gas created by dying stars that are shedding their outer layers. When new ejections encounter older ejections, the resulting energetic collisions shape the nebula. The mechanisms underlying such sequences of stellar mass expulsion are far from fully understood, but researchers theorize that binary companions to the central, dying stars play essential roles in shaping them.

This bug is being bugged (by me). I'm trying to hold the camera still but I guess my hands were shaking bad, thus, it's not that good of a macro shot.
It’s that time of year when stink bugs think they should be living inside the house. This one was on my office window back in April 2016. The ones that enter get gently picked up with a tissue and escorted back outside.

Ambush bugs

I think ambush bugs are fascinating. They're like tiny armored vehicles or mini-dinosaurs.

This is my favorite macro pic. I don't know what this guy is called but he's cool! He's sitting on my son's finger.
Ever been bitten by a love bug? 3 Harlequin Beetles on a Hibiscus leaf shaped like a heart. These beetles are sap-suckers and you can see the damage they've done to this leaf.

Shot taken with a drone, a DJI Spark. Hanging around 20 meters above ground level, it maybe shows what a bug can see when he hovers above us.....
Common Assassin Bugs (Pristhesancus plagipennis) have the long head with powerful proboscis. They use the powerful proboscis to puncture their prey. Their legs are long so that they have long attack distance. Adult bugs are brown in colour with transparent wings. Nymphs are dark brown to black with brightly orange abdomens.
