An international team has captured an unprecedented image of a cosmic filament connecting two galaxies. This discovery sheds light on the structure of the cosmic web and its role in galaxy formation.

The filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it and produces light as a result.

Of course, for best results it makes sense to purchase a factory-made spool, but for light experimenting, it’s entirely possible to 3D print your own bi-color filament. Back when [Turbo_SunShine ...

The filament in this lightbulb is a conductor. Some materials let electricity pass through them easily. These materials are known as electrical conductors. Metal is used in plugs to allow ...

It’s easy to forget that these efficient sources of light come in a variety of form ... A custom PCB acts as a hub for all the LED filament spokes. The onboard brains come in the form of an ...
