Nova Events and Characteristics

A sudden increase in brightness, causing a star to shine much brighter for a period, usually visible with a telescope but sometimes even with the naked eye.

A system of two stars orbiting each other, where one star is a large red giant and the other is a small, dense white dwarf.

A star that has exhausted its nuclear fuel and collapsed into a very small, dense object, often the remains of a larger star.

The process of shedding material from a dying star, which then gathers and explodes in a nova outburst.

A large, cool, and red star at the end of its life, characterized by a significant expansion in size.

The Pacific Ring of Fire is a horseshoe-shaped area around the Pacific Ocean known for frequent seismic activity like earthquakes and volcanic eruptions.

Taiwan is located on the 'Ring of Fire' and experiences regular earthquakes due to its position on the edge of the Pacific plate.

A strong earthquake in Taiwan in 1999 caused significant damage and loss of life, highlighting the importance of preparedness.

Advanced warning systems, regular earthquake drills, and strict building codes all contribute to minimizing casualties during earthquakes in Taiwan.

Landslides caused the majority of the casualties in the recent Taiwan earthquake, highlighting the importance of mountain area safety measures.

A drastic reduction in the amount of plastic manufactured, aiming to reach 60% less production by the year 2040.

Single-use plastics are disposable items made from plastic, such as bags, straws, and food containers, intended for a single use before being discarded.

The fast fashion industry is characterized by rapidly changing trends and low-cost clothing production, leading to a high volume of clothing disposal and plastic waste.

Microplastics are tiny plastic particles less than 5 millimeters in size that can be found in various environments, from oceans to our bodies, posing potential health risks.

Sustainable plastic substitutes are materials developed as alternatives to traditional plastics, offering reduced environmental impact and potential for recycling or biodegradability.
