Study Notes

Nova Explosion

A nova only occurs in binary star systems consisting of a "dying" star, typically a large red giant, and a "dead" star, also known as a white dwarf
Material shed by the red giant accumulates on the surface of the white dwarf, resulting in the gathered material exploding in a burst of energy known as a nova
The nova eruption, T Coronae Borealis, will be visible with the unaided eye
NASA expects the nova explosion to occur sometime before September 2024
T Coronae Borealis is a binary star system located approximately 3,000 light-years away from Earth
It is known for its periodic nova outbursts that occur roughly every 80 years
The last outburst was in 1946

Earthquakes in Taiwan

A 7.4 magnitude earthquake struck Taiwan’s east coast in April 2024
The quake was felt across the country and as far away as Hong Kong and Shanghai, China
At least 13 people were killed and over a thousand were injured.
Taiwan’s earthquake preparedness is considered among the most advanced in the world
Taiwan has implemented strict building codes, a world-class seismological network, and widespread public education campaigns on earthquake safety
Taiwan is located along the "Ring of Fire," the largest and most active of the nine tectonic plates covering the Earth's surface

Plastic Pollution

Earth Day, celebrated every April 22nd, is an annual reminder of the urgent need to protect our planet
The Earth Day Network (EDN) now has over 50,000 partners in more than 190 countries
The 2024 theme is "Planet vs. Plastics"

Cole Brauer's Sailing Achievement

Cole Brauer has made history as the first American woman to sail alone around the world without stopping
Brauer completed the 30,000-mile (48,280 km) Global Solo Challenge on March 7, 2024, in just 130 days
Brauer's journey aboard her 40-foot (12-meter) racing vessel, First Light, began from A Coruña, Spain, on October 29, 2023
She sailed down the west coast of Africa, then over to Australia, and around the southern tip of South America before returning to Spain
The Global Solo Challenge is a difficult sailing race around three "great capes:" Africa's Cape of Good Hope, Australia's Cape Leeuwin, and South America's Cape Horn

Chimpanzee Warfare Tactics

Chimpanzees employ human-like military tactics to assess risks and expand their territories
Researchers used GPS trackers to follow the chimps for 8-12 hours daily from 2013 to 2016
Both groups regularly patrolled the edges of their territories, forming small, coordinated groups
Chimpanzees also sought higher ground along the borders, likely to listen for noises from rival groups
Chimpanzees climb to higher ground to watch for predators, but also use elevation to assess the risks of conflict with other groups
