About any sentence that you can make like: " the astronaut works for Nasa." Notice the "the" at the start? That is the mostly used word for "astronaut".
"An astronaut" is the correct form, not "a astronaut." "an" is used instead of "a" whenever the word it modifies begins with a vowel.
Gold is used in astronauts' helmets because it is an excellent conductor of heat and reflects infrared radiation. This helps to regulate the temperature inside the helmet, protecting the astronaut from extreme temperature fluctuations in space.
An astronaut on the moon would use a spacesuit for protection, a helmet for oxygen supply and communication, gloves for handling equipment, and boots for walking on the lunar surface. Additionally, they would use tools and scientific instruments to conduct experiments and collect samples.

Visors and sunglasses are typically used to block out the sun. You can usually wear either or both even while wearing a helmet. Sunglasses and visors come in a variety of tints and colors.
Carbon fiber is a lighter and stronger material to use and would theoretically be an ideal material to use for a football helmet. The problem is that carbon fiber has poor impact resistance. The University and Oregon University worked on a project to make a complete uniform out of carbon fiber. Article below. http://www.carbonfiberguru.com/2010/01/23/oregons-carbon-fiber-footbal-helmets/

Goliath's helmet, as described in the biblical account in 1 Samuel 17, was made of bronze. While the text does not specify a color for the helmet, bronze typically has a metallic, golden-brown appearance. Therefore, one can infer that Goliath's helmet would have had a bronze-like color, reflecting the properties of the material used.

Velour material is material used to make tracksuits etc.
It’s unlikely that real hair would be hanging from a helmet, as most helmets are designed for safety and practicality. If you see hair-like material, it could be synthetic fibers or decorative elements. In some cultures or events, real hair might be used for traditional or ceremonial purposes, but this is not common in standard helmet designs. Always check the context to determine what the material might be.

The pith helmet was first used in the 19th century. The helmet was made of cork or pith and was worn by many Europeans in the tropics. The pith helmet is also known a Safari helmet or sun hat.
The benefits of a Protec helmet are many. This helmet has been called the 'classic bike helmet'. It protects your head when you are participating in sports that can cause damage if a helmet is not used.
