Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Evaporating gaseous globule?Approximately 100 astronomical units (AU) in diameter
2. What is the composition?Primarily dense molecular hydrogen gas and dust
3. What is the shielding mechanism?Protects internal material from ionizing ultraviolet radiation from nearby massive stars
4. What is an evaporating gaseous globule (EGG)?An EGG is a dense clump of gas about 100 astronomical units wide that hides baby stars inside a giant space cloud.
5. Why do EGGs protect baby stars from UV light?The dense gas inside an EGG blocks the harsh ultraviolet light from nearby hot stars, keeping the material cool so gravity can pull it together.

Photoevaporation: The process where intense radiation from stars erodes and disperses surrounding gas and dust.
Gravitational Collapse: The inward movement of matter under its own gravity, leading to increased density and temperature.
Protostar: An embryonic star in the process of formation, prior to the onset of nuclear fusion.
Nuclear Fusion: The process powering stars, where atomic nuclei combine to form heavier nuclei, releasing energy.
