The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.

Dino Hunt 2, a simple 3D game in which the user attempts to kill a set number of dinosaurs before the dinosaur(s) can kill them. Connection , a line puzzle game. Tiny Moonsters , a game where the objective is to slice different shapes apart without coming into contact with any of the bouncing "Moonsters".
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius.The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars.
NGC 6914 is a reflection nebula located approximately 6,000 light-years away in the constellation of Cygnus, and was discovered by Édouard Stephan on August 29, 1881. [3] Ultraviolet radiation from stars in the Cygnus OB2 association ionize the nebula's hydrogen.
A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon, which directs focused energy toward a target using atomic scale particles.
The superbubble Henize 70, also known as N70 or DEM301, in the Large Magellanic Cloud [1]. In astronomy a superbubble or supershell is a cavity which is hundreds of light years across and is populated with hot (10 6 K) gas atoms, less dense than the surrounding interstellar medium, blown against that medium and carved out by multiple supernovae and stellar winds.
These glass filters can crack unexpectedly from overheating when the telescope is pointed at the Sun, and retinal damage can occur faster than the observer can move the eye from the eyepiece." [ 3 ] Solar filters are used to safely observe and photograph the Sun , which despite being white, may appear as a yellow-orange disk.
